Subject: Re: [korgpolyex] 7 Osc stacked voice - Seenthysizer

Thanks, glad you like it.

Right now I'm taking a break from working on it at the moment

hope to add another 7 osc voice to it soon so two notes can be played at one time.


I need to figure out how to do portamento and freq. modulation to the osc's.  Its a bit more tricky to do than modulating the filter or amp since there isnt support for it in the Audio Library yet.
I would have to deal with a ~2.5ms update delay for each freq. adjustment/change..  not sure how alaised that will sound for a long portamento or how fast a LFO could swing pitches.

The Library didnt really have a decent ADSR.  I had to figure out how to make one myself.. it still needs work.


This DSP power of these boards/chips is amazing though.  I have a feeling I have a lot more CPU power left to use up before it begins to peak out.  And if more power is needed, for $5 more the Teensy 3.6 can be had for 33% more CPU power and 2x more memory.

I post the code for anyone to see, it's at
