You need to enable one of these emulators

If you want to "solo" a voice/chip, hold down Shift while pressing the hotkey.

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.

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 WebSid, but it is not reflected on this page.)

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.

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.

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.

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 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.

If the playback is choppy, try increasing the buffer size. Smaller values mean faster and smoother updating (default is 1024 which is the lowest possible) but also require a fast computer with a nifty web browser.

This does not work in Compute's Gazette SID Collection as CSDb has almost no data for it.

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 release lists and pages from CSDb as you click SID files.

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).

If available, this tab will show information about the editor/player that made the song.

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're clicking a song in Compute's Gazette SID Collection that has lyrics, this will be shown here and in the box.

For more information about STIL, please refer to this FAQ .

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.

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.

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.

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 click a SID file that has been remixed into modern forms, this tab will show those entries from Remix64.

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 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.

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.

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 .

Frequently Asked Questions

How do I register?

The user name and password boxes are used for both registering and logging in. To register, just type the user name you want. If it is available (a status message tells you) then type a password and hit the button.

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 implemention was inadequate for DeepSID.

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 (in the top, not Disqus).

Start finding awesome SID tunes in the HVSC or CGSC folders. When you find one you like, right-click it. A context menu appears. Choose to add it to a new playlist. Browse to the root. Your new playlist should now be there in the bottom with the SID file name. Right-click your playlist folder and choose to rename it. Continue with other awesome SID tunes, only this time choose to add them to your existing playlist. Inside your playlist, you can right-click SID files to rename or remove them, or set a different default sub tune. If you later want to share your playlist, you can right-click the playlist folder and choose to publish it. Or, if you later hate your playlist, you can right-click the playlist folder and choose to delete it.

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?

It's where you choose a handler for the SID files. Some are JavaScript emulators, some are real C64 recordings played with a normal audio player, and one can use your favorite offline player.

Handler Description WebSid emulator This is the JS emulator originally used by the Tiny'R'Sid web site. It emulates standard SID as well as digi tunes, 2SID and 3SID, and even MUS files in Compute's Gazette SID Collection. This is the best quality version of WebSid with cycle-by-cycle processing. WebSid (Legacy) This is an older version of WebSid from before it was overhauled to cycle-by-cycle processing. It's faster and has clearer digi sound, but it doesn't emulate quite as faithfully. If your computer has trouble keeping up with the above WebSid version, try this one instead. Hermit's emulator Hermit's jsSID emulator is extremely compact and can play standard SID as well as 2SID and 3SID. Unfortunately it can't do digi tunes, but it makes up for that by being a steadfast emulator. Download SID file This makes the browser download the tunes. This is especially useful if an offline player has been associated with automatically playing it. Then it's like having an extra play option.

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.

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 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?

Hit p in desktop web browsers to pop up a tiny version of the player.

Hit s to toggle minimizing or restoring the sundry box.

You can hold down the key just below the ESC key to fast forward.

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?

See that blue bar just below the top box with the title, author and copyright lines? It's the C64 memory, from $0000 to $FFFF. The dark blue blob that appears there is the SID tune as it takes up space. If you hover your mouse pointer on it, the tooltip will tell you the memory boundaries in hex and the size in bytes.

If you want a box with this information and more, click the Visuals tab and then the MEMO button. And nifty shortcut to this is to just click the dark blue blob in that blue bar mentioned before.
