The idea was to add Free Env 2 as an oscillator source for an easy way to get a triangle wave. The oscillator starts and ends at -1. The total length of the wave is 2.56 and the sample array is 1024. If the 3 stages are less than 2.56 then a flat top is added. If the stages are over 2.56 then stages get chopped.
While I was at it, I also added Free Env 1. The envelope is positive and rotated 180 degrees for the negative half. I added the 2 step sequences as oscillators. At 128 samples they are pretty lofi. I'm not sure how useful they are but they are there. :)
Lastly, I added a wave folder to the FX section. Probably, only useful in mono sounds.
As the envelope / step seq stages are only set by the encoders except the 'silence', I thought this would be a cool way to get a changeable triangle type oscillator. Though, I might try to add Free Env 2 attack and decay destinations to see if I really can break something. :)

cheers will try it out tonight :)

Oh yeah :)
Very good idea to use the modulators as oscillator.
Congrats to dig in the code... I knew your sound design skills but didn't know you were a developer. 8)
I cannot try it tonight...
What is a wave folder FX ?

funkyfli awesome idea for using the envelopes as oscillators! I like the idea of doing a wave folder FX.
-
:) A wave folder, instead of clipping the wave at a limit, folds it back on its self. The one I wrote amplifies around zero and folds back at -1, 1 and 0. So the positive and negative parts stay on their respective sides. Fun for simpler patches...
Enjoy... hopefully :)

Thats interesting, thanks for sharing the info! :)
