Yeah, $08 on the first frame before you set the gate will give you a solid start.  Have the gate set for two frames to give it a really solid start before switching it off. (eg: $08,$41,$41,$40)

Converting a playing sid tune to midi data and outputting to Windows general midi through a Sequential cart.

It stopped being a niche and people use it in all kinds of music now... whether that was through the retro games revival or through the chiptune scene, either way it's good right?

I wrote a tutorial on how to play your own SID tunes with FMX which you can read here , it only covers single SID tunes but the docs show how to expand on this.

Oh, if I ever finish this there'll be a cross-platform one that supports Viznuts's wave effects.  Or you can use the source code right now.

So we should start a bounty for this +VICMIDI support?

I don't think there's enough of a fanbase for the Vic tbh.

Currently going on over at CSDB until the 17th March.  Only triangle wave, test bit and filter allowed, lot of interesting entries from lft, Jammer, Jellica, LMan and Jeroen Tel so far among others.

Ah, yeah could be, I'm not sure how it works with other devices.  Most of a frame it's not using the SID chip, but at the end it writes to all 25 SID registers in one go.   I wrote a quick 'behind the scenes' on it which you can find here.   It has a few things about playback in there.

The only problem is, many SID files don't load even though they are below 8kb. I don't know of a way to check in Windows, where the tune tries to load, and often Patchwork crashes after trying to load a SID that would occupy an invalid memory range. The error message is:"outside ram si"

Thanks I'll take a listen to your soundcloud upload.  Yes SID files have to be in that $1000-$2fff range, Most sid players should have an info window that tells you the load address.  (Vice comes with VSid for example)  The other thing you can try is relocating them using SidReloc (there's a link in the readme) which can get most tracks into the correct memory space.   Patchwork will also refuse any files that are multispeed or use timing other than the standard vblank.

The GUI is absolutely insane. Specialy the "SMPL" window.

Yes it does look a bit weird, what you're seeing there is what waveforms are playing on each channel: 1/2/3 and then the filter cut-off at the bottom of each vertical strip.  Each step horizontally is a frame of music, kind of like a sample display.  Whatever the vertical line is over is what's playing right now.

Thanks.  Here's a video of some example tracks with their source material, and the liveplay mode being used.

Patchwork is a small sound sequencer that uses parts of recorded sid songs for instruments. It is mostly a proof-of-concept, just to see if this kind of player would work. Though it can be used to make grooves, small remixes or loops.

Thanks, I'll keep the HerMIDI one in mind too.

Just out of interest, which of the midi interfaces/protocols are people using on the c64?   Looking at the specs they all have a similar setup though the addresses spaces change a bit.   There appear to be 4 I've found info on:

Sequential Circuits
Passport
Datel
Namesoft

Lost for 25 years until an archive team found it.

Lets you record sounds/loops from sid files and resequence them into new things.
