DeepSID is an online SID player for the High Voltage SID Collection and
more. It plays music created for the Commodore 64 home computer. Click any of the folder items below to start browsing the collection.
If the playback is choppy, try increasing the buffer size. Smaller values mean faster and
smoother updating (1024 is the lowest possible) but also require a fast computer with a nifty web browser.
The piano is always updated as fast as possible when using the normal WebSid emulator, regardless of buffer
size. However, larger buffer sizes may introduce flickering notes. Decrease the buffer size to avoid this.
The top right waveform legend explains the colors of notes on the keyboards. Red is pulse,
green is triangle and blue is sawtooth. Gray is noise. Waveforms may be combined, but 31, 61
and 71 are only audible on the 8580 SID chip.
The numbers above the bars are hexadecimal.
Pulse width has 12 bits and goes from 0 to 4095.
The triangle indicates that it's most audible in the middle. The filter cutoff has 11 bits
and thus goes from 0 to 2047.
The small yellow bar is the filter resonance. It can go from 0 to 15 (maximum resonance).
Resonance is a peaking effect which emphasizes frequency components at the cutoff frequency
of the filter, causing a sharper sound.
RM is ring modulation (non-harmonic overtones) and HS is hard synchronization (complex
harmonic structures). Both effects require two voices – the previous voice as the
carrier and the current voice as the modulator.
Sometimes the use of gate bit (i.e. when the piano key is depressed then later released) make
notes too quick to sense, or it may in some cases even hide them. Turning it off with the
toggle button in top can amend this.
Click the green buttons to toggle voices ON or OFF. You can also type
1, 2 and 3 or alternatively q, w
and e. (You can also use 4 and r for digi if you are using
legacy WebSid, but it is not reflected on this page.)
2SID and 3SID tunes are supported. Each keyboard will automatically combine
to host an entire chip (i.e. 3 voices). The square voice buttons will toggle entire SID
chips ON or OFF when playing these types of tunes.
If you want to "solo" a voice/chip, hold down Shift while pressing the hotkey.
You need one of theseDecrease if too slow

Notes
Use the smallest buffer size (1024) for best effect. Especially the vibrato detector needs this.
Lines detecting repeated changes typically requires about four unique values to occur.
Using illegal waveform to lock noise, then unlock it with test bit, can be used to create unique sounds.

This tab will show release lists and pages from CSDb as you click SID files.
CSDb, short for The Commodore
64 Scene Database, is the largest and most comprehensive database about C64 releases
pertaining to the demo scene. It's where all the cool dudes go to hang out.
This tab will show links to game entries in GameBase64 as you click SID files that were
used in at least one C64 game, released or unreleased (these are listed as a preview).
GameBase64 is a large database
for C64 games with credits, details and screenshots.
This is a list of all the players/editors in the database. If you click to see
a page, the SID browser will automatically find all tunes related to it. Most CPU time measures you
see here were made with SIDDump and are approximate.
X-SID 2007 by Jeff Native / C64 emulator28-30 rasterlines
This tab will sometimes show one of two things depending on the SID collection you're browsing.
It will display the same contents as the first tab in the box just above the player controls.
STIL
If you're clicking a song in the High Voltage SID Collection that has a STIL entry, this will be
shown here as well as in the box. Any sub tunes mentioned have green buttons that you can click.
STIL stands for SID Tune Information List and contains information beyond the standard
TITLE, AUTHOR, and RELEASED fields. This includes cover information,
interesting facts, useless trivia, comments by the composers themselves, etc. The STIL, though,
is limited to factual data and does not try to provide an encyclopedia about every original artist.
For more information about STIL, please refer to this FAQ.
Lyrics
If you're clicking a song in Compute's Gazette SID Collection that has lyrics, this will
be shown here and in the box.
Technically, lyrics are always added in a separate WDS file that accompanies the MUS file that
contains the actual music data. However, not all MUS files have a WDS file. Roughly one third
of the MUS files in the collection have lyrics.
If you click a SID file that has been remixed into modern forms, this tab will show
those entries from Remix64.
Remix64 is a portal to the unified world
of Commodore 64 and Amiga music remixing, containing news, reviews, charts and chat. Remixes
can be uploaded and rated here. It's maintained by Markus Klein, also known as
LMan.
If you register and log in, you can adjust your settings here.
About
DeepSID is an online SID player that can play music originally composed for the
Commodore 64, a home computer
that was very popular back in the 80's and 90's. This computer had an amazing sound chip
called SID.
The SID chip was really ahead of its time. Although it only had 3 voices, it offered
oscillators of 8 octaves, ADSR, four waveforms, pulse width modulation, multi mode filtering,
ring modulation, and hard synchronization. It really was like a tiny synthesizer, and you
could even make it play digi samples along with the SID voices.

The images for composer profiles come from all over the internet. I have tried
to be fair and not use images that the composer did not already have available on a personal
web site, social media, interview, or another public place.
Most are publically available profile images from Facebook or LinkedIn.
A lot of older retro images (typically lo-res) are from the musicians photos download at GameBase64.
Some were originally taken by Andreas Wallström (C64.com).
And several other places I can't remember anymore.
If you feel you should be credited, let me know and I will add you to this section. Also, if
you don't like an image of you here, just let me know and I will of course remove it. You are
also welcome to send me a replacement image.
The previous method of registering has been reworked for clarity. Now just click the 'Register' link
above the user name and password boxes to begin the registration process.
The annex box also has information about what you can do when logged in: Registering
Can you please make an app or an offline version?
I wanted to make an awesome online web player for SID tunes and I believe I have accomplished
that. It was never my intention to make an app or an offline player. An online player gives me
immediate access to e.g. HVSC and CGSC without having to download anything first. Just
everything ready to play, search through and rate no matter if I'm on my desktop, on my iPhone
or on my iPad.
However, it's possible to use an offline player with DeepSID. Just select the
Download option in the top drop-down box and start clicking rows. Make sure you
associate your offline player with automatically playing the tunes.
Where did the audio handlers for SOASC go?
The audio handlers for Stone Oakvalley's Authentic SID Collection were removed in September 2020.
The connections to these real-time recordings were always spotty at best and later the reaction
times also became painfully slow.
I have repeatedly tried to fix the reaction times to no avail. It's a shame having to leave this
library behind as it would have been nice with real-time recordings to complement the emulations,
but I finally decided that the quality of the SOASC implementation was inadequate for DeepSID.
It was removed in late November 2020 together with all of its script code. It affected the performance
of DeepSID, especially when triggering new SID tunes. Because this comment system was already rarely
used by users, I decided to remove it altogether. The comments are still stored on their side and can
be exported.
How do I make my own playlists?
You need to be using a mouse to create and manage playlists. This cannot be done on a mobile
device (although you can enjoy your existing playlists there). Also, you must of course be
logged in.
The annex box has the basic instructions: Playlists
Published playlists appear further up in the root and can be seen by everyone (even those that
are not logged in) but you're still the only one that may edit it. When you enter a public
playlist, you can see who made it.
What are those options in the top left drop-down box?
Why can't I see the right text area on mobile devices?
That's by design, actually. Only the player pane is supposed to be visible on mobile devices
because of the limited screen space. This right text area is only really available for desktop
computers.
Can you add a playlist randomizer?
You can achieve the same thing by selecting the Shuffle option in the sort
drop-down box.
Can I search for a range of ratings?
Yes, if you type e.g. 3- for a search for ratings, you will get a list of all the
SID tunes and folders you have rated three stars or more. If you type 1-, you will
see all of your ratings.
The annex box can show you a list of all the search options: Searching
Can I turn voices on and off?
Yes. Use keys 1, 2, 3
and 4 or alternatively q, w, e and
r. The first three are for the normal SID voices and the fourth is for toggling any
digi stuff (WebSid (Legacy) emulator only).
If you want to "solo" a voice, hold down Shift while pressing the hotkey.
In the piano view, you can also click the green number buttons.
Any other hotkeys worth knowing about?
The annex box can show you a complete list: Hotkeys
If you hold down Shift while clicking rating stars, you will clear them. (However,
it's usually easier just to click the same star again if you want to clear the rating.)
Why doesn't this work in Internet Explorer?
The audio handlers all use an API called Web Audio which is
not supported by Internet Explorer.
You need a modern web browser to use this site.
Why can't I see the load/end addresses and size of the SID tune?
Actually, you can. The annex box has the answer: Memory bar
What URL parameters are available?
The annex box can show you a complete list: URL parameters
DeepSID's copy of Compute's Gazette SID Collection has now been upgraded to version 1.47.
You can now see the song length in the bottom right corner of SID rows (except in the SID Happens folder).
For songs with multiple subtunes, the song length for the default subtune is shown.
August 7, 2025
The tags can now be toggled on and off with the "y" hotkey.
August 4, 2025
The search limit has been increased from 1000 to 2000 results.
August 2, 2025
The STIL/Lyrics tab now also shows a cyan notification icon when it has contents.
Fixed a console log error when browsing Compute's Gazette SID collection.
The 'Noise Waveform' toggle in the 'PIANO' view has been fixed and should now work 100% correctly.
The 'Slow speed' toggle in the 'PIANO' view now remembers its slow state for Jürgen Wothke's SID emulators.
The composer avatar is no longer shown in the top-left info box when using the YouTube SID handler.
August 1, 2025
Folder rows now display a dollar icon for professional musicians who composed music for commercial games.
July 30, 2025
In the 'Edit Tags' dialog box, the 'Music', 'Collection', and magic wand buttons can now be
middle-clicked. Doing so will perform the action and automatically click the 'OK' button.
July 29, 2025
A new magic wand button has been added to the 'Edit tags' dialog box. When clicked, it presets the
two drop-down boxes with the most logical combination of an event and production tag.
July 28, 2025
The large-font text beneath SID rows for 2SID and 3SID tunes has been removed. Instead, a new blue or
red label is now shown at the end of the SID filename, just before the rating stars.
July 27, 2025
The "Music" and "Collection" tags now have their own toggle buttons in the 'Edit tags' dialog box.
July 26, 2025
Fixed a bug where clicking 'BACK' from a CSDb release page sometimes displayed a reduced list.
July 25, 2025
All images from CSDb are now cached after their first display to reduce the overall load on the CSDb server.
DeepSID now caches CSDb data, such as release and SID pages, to improve loading times and reduce reliance on the CSDb server. Fresh content is still fetched in real-time, while older pages are served from the cache since they rarely change. If CSDb is temporarily unavailable, DeepSID will automatically fall back to cached versions when possible. The cache builds gradually as users browse, so its benefits increase over time.
July 24, 2025
You can now click the composer avatar in the top-left info box to go to the composer's home folder. This also works while already in the home folder, allowing you to reset the view.
Fixed missing database information for Jungle.sid by Mixer.
Fixed missing database information for Medley.sid by Nordischsound.
Most collection folders now display the number of folders and files below the path line.
The composer avatar now also appears in the top-left info box when available.
July 21, 2025
The author highlighting previously only available in the CSDb list can now also be seen on CSDb release pages.
The new toggle button in CSDb lists is now only enabled when there are highlighted entries.
The stars around the "Winner" tag made it too wide. I removed them and turned the tag into gold instead.
July 20, 2025
You can now use Shift+Backspace to go back from any tab page with a 'BACK' button.
Added a toggle button to CSDb lists to show only highlighted entries, prioritizing those where the copyright line contains the group name, or where the composer's group, previous groups, real name, or handle matches.
You can now navigate the SID folders using keyboard controls — specifically, the arrow
keys (up/down), Home, End, Page Up, Page Down, and Enter to select a SID row. Press Backspace
to go back one folder. This new feature is currently in BETA and took quite a bit of tweaking
and testing to get right. I’ve done my best to iron out all major bugs, but there may still be
minor glitches. Note that in some browsers, such as Chrome and Edge, keyboard navigation is
throttled slightly to avoid stuttering. Firefox, on the other hand, has better keyboard handling
and moves at the maximum speed possible.
July 9, 2025
The "Coll." tag has been replaced with a double note icon followed by a list icon. It now
appears second among the blue production tags, just after the "Music" tag. You can still use
"Collection" to search for or add it.
July 8, 2025
Fixed an issue where pressing 'Space' to pause/play would also scroll down the song list.
You can now use the left and right arrow keys to skip to the previous or next SID row. The new
selection is centered, just like when using the control buttons. If you hold down 'Shift' while
skipping, the auto-progress setting from the setup is applied. If auto-progress is set to 'Off',
the selection won't be centered.
July 7, 2025
Added the CSDb music competitions related to HVSC #83.
In the CSDb tab, in addition to the usual rule where group names are highlighted in various colors,
a scener's real name or handle may now also be highlighted in red if it matches a release.
July 6, 2025
You can now edit the tags for the currently selected song by hitting the "t" key.
The "Collection" tag has been abbreviated to "Coll." in the blue tag, as it could be
quite visually dominant. However, you can still search for and select it using "Collection".
The cause of death for deceased composers has been replaced with their age at the time of death.
If a birth year is known, the current age is shown for composers who are still with us.
The "DL" download links have been removed from CSDb lists shown when there is more than one
release for a song. You now need to open a specific CSDb release page to find any download links.
Removed the double note icon in the "Compo" tags, as the new connection system for tags can make it
more obvious what the "Compo" tag and # ranking applies to.
2SID and 3SID tunes are now easier to spot thanks to large-font text displayed beneath the SID rows.
July 5, 2025
The 'Edit tags' dialog box now has two new drop-down boxes for optionally selecting a start and end tag.
Setting both creates a horizontal line below the tags in the SID row, showing the connection between them.
This can be used, for example, to show that a SID tune was released at a party where it was used in a demo.
I will gradually begin using this new feature by adding connections here and there.
July 1, 2025
All new files in HVSC #83 are now connected to CSDb entries.
June 30, 2025
Fixed missing database information for N0s_Intro_83.sid by Glenn Rune Gallefoss.
June 29, 2025
The blue "Music" tag (used for music releases) is now displayed as a double note icon without its name.
It also always appears first among the blue production tags. (To add the tag in the dialog box or search
for it in the bottom, just use the "Music" name as usual.)
Validated the look-up of all players with a player/editor page and fixed those that didn't work.
Added composer profiles for the new folders in HVSC #83.
June 27, 2025
In the CSDb tab, in addition to the usual rule where group names are highlighted in yellow or blue when they
match the group in the tune's copyright line, group names may now also be highlighted in green if they match
any other group the user has been a member of. This can sometimes make it easier to find the right entries.
June 26, 2025
Fixed FlexSID tunes not showing the relevant player/editor page.
June 25, 2025
The blue "Collection" tag now shows a double note icon too, since it's for music competitions.
June 23, 2025
The left and right arrow tag icons (introduced June 19) have been revoked, as they were too confusing.
The "Compo" tag now shows a double note icon to make it clear this tag is for music competitions only.
June 22, 2025
Headers on the CSDb and GB64 tabs now handle long titles without overflowing.
All page tabs now use the same sticky header bar as the CSDb and GB64 tabs.
The "No SID Handler" option has been added. It obviously plays no music, but can be handy when
you just want to browse for information. The auto-play overlay is not shown either.
June 21, 2025
The dialog box for editing tags now scrolls both lists to the top when opened.
After clicking a SID row in the folder list, you can now use standard navigation keys such as
Home, End, Page Up, Page Down, and the arrow keys.
Made the "Winner" tag a bit snazzier so it stands out more.
June 20, 2025
The scroll position is now remembered when refreshing the current folder with the "f" key.
June 19, 2025
Left and right arrow tag icons have been added. These always appear between event (green) and production (blue) tags.
A green event tag with a right-pointing arrow toward a blue production tag (e.g. a demo) indicates that the SID file was
created specifically for that production, which was released at the event.
If the arrow points to the left instead, it means the SID file was released at the event but not made for a particular
production and did not participate in a music competition.
You can now refresh the current folder by hitting the "f" key. This will also go back to the top of the list.
June 15, 2025
You can now click any screenshot (not just in the GB64 tab) to view it at three times its original size.
Fixed temporary emulating testing (hotkey "l") not showing the correct number of subtunes for a song.
The GB64 tab now uses the same sticky header bar as the CSDb tab.
June 14, 2025
The registration process has been reworked. There is now a 'Register' link above the user name and password fields that
you have to click in order to register a new user. The removal of the previously automatic registration should also mean that
automatic login on mobile devices should work properly.
Upgraded the JSIDPlay2 emulator. It now uses WASM_GC (Web Assembly Garbage Collector) and is estimated to be 10%
faster than the previous version.
June 13, 2025
The "Game" search type now searches the imported GB64 database directly. Note that you will only get results if the game
you're looking for actually uses a SID file in the High Voltage SID Collection.
You can now click a GB64 screenshot on a game page to view it at three times its original size.
Fixed scroll position not being restored when browsing back from a search state.
Fixed SID row not centering correctly when skipping to the previous or next tune.
June 9, 2025
The "Game" and "Game Prev" tags will automatically be removed if a "GameBase64" tag either
exists or is added when GB64 entries are detected. The tags will not be affected if the SID row does not have any GB64 entries.
June 8, 2025
Fixed an issue where the GB64 tab sometimes showed irrelevant screenshots for a game.
The remix tab is working again.
If you click a song and DeepSID detects that it has entries in the GB64 tab, a "GameBase64" tag
will automatically be added to it if it doesn't already have it.
June 7, 2025
The GB64 tab is back, showing game information from GameBase64 whenever a SID file is used in one or more games.
DeepSID now uses an imported database instead of scraping the site, which is both safer and faster.
Clicking a game in a list of multiple GB64 entries now shows the game page instead of jumping to the site.
June 6, 2025
Improved phrase searching. Now searching e.g. filenames for "the party" (including the quotes) only return
the entries where the words are truly consecutive.
Fixed a detection bug where the filter controls didn't show or hide correctly depending on whether the SID tune clicked was
made for 6581 or 8580.
May 24, 2025
The JSIDPlay2 SID handler now has its own unique time bar color.
March 15, 2025
Thomas Jansson (tubesockor) fixed a 6510 emulation issue in Hermit's driver causing incompatibility with some tunes.
Some instructions were push/popping the stack in a reverse order than expected on 6510.
Huge thanks to Anthony Bybell who discovered this anomaly.
February 2, 2025
Fixed too many bytes showing red colors in the MEMO view, when starting a tune.
Fixed the pace field in the MEMO view not always showing the correct information.
January 12, 2025
Added the CSDb music competitions related to HVSC #82.
January 11, 2025
All new files in HVSC #82 are now connected to CSDb entries.
JSIDPlay2 has been changed to WebAssembly and it should now be fast enough to play stereo tunes on mobile devices.
It should play at least 40% faster.
November 8, 2024
A new SID handler with WebUSB support for USBSID-Pico has been added to Hermit's emulator by LouD.
Note that WebUSB can be quite demanding resource wise.
October 19, 2024
Fixed sid model and clock speed info flags not always showing the correct information.
October 13, 2024
Ratings stars for a song are now shown in the info box too, so you can see and rate the song even when you have browsed away from it.
The collection version number has been moved down above the sundry box.
Fixed an UTF-8 issue due to an update on CSDb. All CSDb pages should display properly again.
September 28, 2024
A new tag group type for events has been created. These tags have a green color and are shown before all other tag types.
They are used for events such as demo parties. The event name always come first, then optionally "Compo"
which can then optionally be followed by the ranking such as "Winner" and "#1" to "#9" tags.
August 4, 2024
Fixed temporary emulating testing (hotkey "l") not playing the uploaded tune when clicked.
July 25, 2024
Added the CSDb music competitions related to HVSC #81.
July 21, 2024
The "Compo", "Winner" and "#1" to "#9" tags now always huddle together in a logical manner.
July 20, 2024
The sundry tab for stereo is now also available for JSIDPlay2. Here you can set sliders for balance and delay,
change the stereo mode, and toggle fake stereo along with the SID chip to read from.
You can now hit the BACKSPACE key to go back to the parent folder.
July 18, 2024
Fixed main volume not being remembered when refreshing the site.
July 17, 2024
Advanced settings has been added in the settings tab. Its contents will depend on the SID handler chosen. There
are only advanced settings for JSIDPlay2 to begin with.
Moved the buffer size in the settings tab into the new section for advanced settings.
Added some advanced settings for the JSIDPlay2 emulator – default emulation (reSID or reSIDfp) and
sampling method (Decimate or Resample), plus a ton of filter names for 6581 and 8580 chips.
Selecting a different SID handler now always refreshes the site, instead of just a select few. To make up for this, the tab
you're in is remembered every time you change the SID handler.
All new files in HVSC #81 are now connected to CSDb entries.
July 15, 2024
Fixed a bug when refreshing the site while using other SID handlers than WebSid HQ, Legacy or reSID.
July 14, 2024
Added a SID handler for another reSID emulator, this time 'WebSidPlay' by Jürgen Wothke (called 'reSID' here
to avoid confusion). It's a port of libsidplayfp
and is only 30% slower than WebSid HQ, making it a great choice for excellent emulation.
The new reSID handler is in BETA and still have the following issues:
Reading the digi type and rate is not supported yet.
Reading the SID registers is slow on big buffer sizes and only supports 1SID.
The oscilloscope is not supported yet.
Showing the PAL/NTSC and 6581/8580 flags is not ready yet.
Advanced reSID settings are not available.
For 2SID and 3SID tunes, the visuals only show the first SID chip.
Exotic SID tunes (4SID and more) are not supported.
Another emulator button for the new reSID emulator has been added in the visuals tab.
Added logic for disabling view buttons (piano, graph, etc.) when a SID handler doesn't support it.
All three emulators by Jürgen Wothke (WebSid HQ, WebSid Legacy and reSID) now share a new and streamlined script player.
DeepSID has been overhauled accordingly to support this.
The scopes for WebSid HQ and WebSid Legacy have been significantly improved, using a new channel streamer script.
Setting a specific buffer size for the scope to work is no longer necessary.
A bug has been fixed in a player script for WebSid HQ. Now the visuals are perfectly synchronized.
July 6, 2024
Upgraded the JSIDPlay2 emulator. An "open" method has been renamed to fix a bug in DeepSID that prevented
certain links to PlayMOD and CShellDB from working, as well as the "p" hotkey for opening a tiny DeepSID.
Fixed the tune timer not keeping up when using fast forward in JSIDPlay2.
Fixed when the tags line for a SID row was not reappearing after showing a loading spinner.
Added composer profiles for the new folders in HVSC #81.
June 29, 2024
Fixed a bug where the piano visuals would appear in the other tabs.
June 28, 2024
Upgraded the JSIDPlay2 emulator. It now has tune length events.
Stopping a tune with JSIDPlay2 now kills the worker thread to save on mobile battery power.
Changed the logic for the loading spinner when using JSIDPlay2. It now clears earlier than before.
The visuals tab is now turned off as default for JSIDPlay2, to save on CPU time.
June 22, 2024
Added a SID handler for JSIDPlay2.
This uses the renowned reSID engine and offers excellent emulation, but it's also considerably
more demanding. You need a powerful CPU to run this one. Only the playback and visuals are supported in this "BETA" update.
Support for stereo and filter presets are coming in a later update.
Because of the new SID handler, an ON/OFF toggle button has been added in the visuals tab. If your CPU is having trouble making the
playback sound coherent, try turning the visuals off. This may especially be helpful with digi, 2SID and 3SID tunes. Turning the visuals
off not only saves time on having to update this, it also turns off SID register output in the JSIDPlay2 emulator.
Fixed tags not being removed too when a loading spinner is shown in a SID row.
Buffer size is now unique for each of the emulators supported by the visuals tab.
May 16, 2024
Hermit's emulator is now capable of playing back SID+FM files. These are SID files combined with
FM emulation and have been accomplished by using either the SFX Sound Expander or the FM-YAM
cartridge. Thank you to Thomas Jansson (tubesockor) for this update.
A new SID+FM subfolder has been created in the SID Happens folder.
You can only enter this subfolder when you have selected the Hermit's (+FM) SID handler in the top left drop-down box.
It's possible to upload new files to this subfolder, but they must of course be of the SID+FM type or they will be deleted.
January 6, 2024
Added the CSDb music competitions related to HVSC #80.

Tips
Warning tags
There are a few tags that indicate some kind of warning.
One or more voices has been copied to play the exact same notes on top of each other. This is usually a lazy editing technique that just makes everything louder.
The tune was originally made by someone else, then stolen and edited to change or add something. Like if someone merely added an extra digi track on top of a tune.
