that's ok varice, looking forward to hear what you can do with it Very Happy

In the meantime Blue Hell was so kind of playing the patch, somehow controlled by the chatroom,
and stream it so I could listen and record. which to me sounded like:

drifting on a cosmic river
alien voices from afar
timelords of the 4th dimension
the rebirth of a dying star

bells of light, refracting photons
mirrors made of mercury
soundwaves trapped inside a diamond
fractalized geometry

so now I have ± 6.5 hours of recordings which I'll probably use in some music. Razz

Your description of the sounds of this patch are very good Exclamation

I agree. They pretty much describe what I hear…

And that Blue Hell guy, he sure seems to be a pretty good and helpful fellow… Wink

That is exactly what I was thinking. With such a complex patch, it is easy to miss something... and that is where other G2 patchers can help. Smile

No way -file this under "Tim is an idiot."! doh

Ummm... no, I won't, Tim Exclamation

It was just a very simple mistake in an otherwise complex and brilliant patch...

Tim this is AMAZING! I haven't had much time to play with it yet (too much work and procastination to do) but I foresee hours of delight and entertainment thanks to this patch _________________ Cheers, Albert

Well the darn thing did keep me busy for a month. Embarassed

Funny though how the most complex part of the design (the offline waveform rendering and the RAM array transfer/multiplexing circuits, and the way they communicate which each other) worked right off the bat. It's the only part of the patch which I would probably have to trace down cable by cable again to remember in detail how it works. Laughing

The hardest part for me was getting the waveform playback 100% glitch-less. Static waveforms are trivial (once everything is sample-accurately calibrated, that is Laughing

), but as soon as you modulate stuff, you're opening up a big can of worms, since waveform-generation and waveform-playback are out of sync in a band-limited re-sampling scenario -something that I hadn't anticipated, or more honestly: hadn't thought through well enough. Embarassed

Suddenly you have generation speed, playback speed, buffer size and modulation update rate interacting with each other. The artifact-free solution, which cross-fades updated waveforms while it also asynchronously conjoins them into a continuous stream at the desired pitch, cost me a sub-oscillator (originally there were two). Sad
