I made this basic polyphonic synth which, with some effects, makes nice sounds.
Use it with a midi keyboard and move the modulation wheel or your ctlin 1.
Thanks for feedback.

alistair_blunt,

Thank you for your patch! It is a lovely sounding synth. I am playing my guitar through it.

I wanted to know if there is an "easy" way to change the timber of the synth tone. I am pretty unknowledgeable when it comes to synthesizing sounds in PD.

What I am looking for is to use another peddle to change the quality/timbre of the tone - perhaps from the sinusoidal tone that you have already in your patch to a more brassy/buzzy/sawtooth tone.

Additionally, one of the things I am running into with you patch is that when I am on the fundamental/bass tone, the volume is very week so I roll in some of the partials and it begins to speak more. but then as I play higher notes, the partials follow and then begin to peak. Is there any way to bump up the gain of the lower partials.

Again, thank you for your patch. I really look forward to integrating it into my rig.

best and thanks for any help,
dkeller

I really like this synth. Good job! I don't really understand the theory behind it, though; I don't know what the cosine waveshapers do or what is going on in the big filter section. Do you know anywhere I can read up on some of the theory? I am only just starting to familiarize myself with some basic DSP mathematics. Maybe I just need to spend some time learning basics before I try to comprehend this.

Dkeller, I tried this synth with a midi keyboard, but I also tried it out with your guitar patch. Nice job with the patch; it does a good job of detecting the notes and turning them on and off. The only problem with using a guitar with a patch like this is that the guitar is obviously monophonic while the synth is polyphonic. I guess it would be nice in this situation to have one of those hexaphonic pickups

I agree that the lower partials are a little too quiet. If I play a lower note on the keyboard I can barely hear it but when I start rolling the mod wheel a bit the higher partials come in and they are a lot louder. It sounds great already but it would be nice to hear a bit more of the droning bass sound.

Hello mates,

Maybe you could solve the difference in volume adapting the abstraction(s) that I posted here:

You can give a single value of ADS and R for every midi note with it.

thank you guys for the kind comments and suggestions and thx to sumidero for the midi-range patch.
I'm very busy right now, I'll try to solve the differet volumes issue asap.
stay tuned
