Well, it's certainly getting there (it is essentially a Solina signal path). The biggest problem is the high pass filtering - it really needs to track the fundamental pitch and that is difficult with a standalone system, especially with a guitar input. With a fixed filter you have to find the sweet spot which barely covers 2 octaves. Outside of that it sounds either like a fuzz pedal or a Kazoo! In a string machine, the filter is fixed, but there's one for every note and its pitch is known. The exception was the Logan that had fixed filtering per voice - but each voice only covers 2 octaves so it got away with that.

I think playing with appropriate articulation is very important. With a fretted guitar I could only impose vibrato which also helps in getting the required sustain, but no proper glide. In a synth, I'd want something that demands the same and similar effort to the finger on a string experience. I know there's so much hate for them, but I always thought ARP's PPC pads were really good for getting a more natural vibrato (the # one for strings of course). Maybe its because I'm left-handed and a guitar player, but I really got on well with them. I have no idea why a keyboard controller couldn't have pressure pads in addition to wheel or stick.

I did this a few months ago, more as an exercise in expression and dynamics than trying to achieve a specific sound....
Very impressive!

That’s are the threads that got me to sign up to muffwiggler.
Thanks so much for this! It’s nice to see a thread I don’t have to “worry about”.
I have to worry about this one. Seems I'm about to waste hundreds of hours on this. :-)

Would it be off topic to suggest a triangle wave?

I did this a few months ago, more as an exercise in expression and dynamics than trying to achieve a specific sound. I can't remember the exact signal path, but the main idea was using the difference patch to control modulation depth. You can hear that higher harmonics come in with louder and higher notes.

Fantastic. Was that with just a static keyboard controlling?

Thank you, and thank you jorg.

No keyboard - it's entirely self-playing. I'll often start with a Krell-ish base. Rather, a function's EOC triggering a sample and hold determines the time of the next cycle. The S&H's input needn't be random. It's such a simple and versatile idea that I keep coming back to it. So the whole patch revolves around that idea and as is often the case I'm trying to get as much movement as I can from as few sources as possible. Case in point - the second "cello" is just the first through a long delay.
