Title: pwm
Post by: lokki on January 29, 2018, 12:35:11 AM

hi there,

i thought about extending the 2048 point square wave to add another 1024 points of "low" so that i could then change the onset (first value to be read from the array when used in an oscillator) via a matrix source. this would allow a pwm effect when square wave is selected, which can be a VERY interesting sound. it is like a speaking synth :-) (at least when i try this on the blofeld, but maybe it only works in pm synths, not true fm)

looking at the square table it is no strict 1 and 0 based square wave, it is somewhat antialiased i think.

could this be feasible?

i would love PWM feature, because i'd rather order more PreenFM2 kits than conventional subtractive synths )

Just off the top of my head, I imagine this approach would cause a lot of aliasing but don't let that stop you trying! I'd love to hear how it turns out.

I used this technique and it gave me a sudo pwm that works really well!
