ten fingers ten toes Posted October 24, 2007 Report Share Posted October 24, 2007 Niiiiiiice! How difficult a project was this? I couldn't hear the mp3 either....

Guest iep Posted October 24, 2007 Report Share Posted October 24, 2007 right the mp3 works now, it is two bits, first a soft wet bit then harsher crunch it wasn't that complex, it is polyphonic but the voices are simple and, for example, instead of proper envelopes i used this system of auxillary lfo-like oscillators that can modulate the amplitude of the voices. total cost of this was about 60 euro's Quote Link to comment https://forum.watmm.com/topic/27506-homemade-polysynth/#findComment-580777 Share on other sites More sharing options...
Hoodie Posted October 24, 2007 Report Share Posted October 24, 2007 The soft wet bit sounds excellent. Good job on making this, it's very nice.

Braintree Posted October 24, 2007 Report Share Posted October 24, 2007 You're missing the flux capacitor and the teltonic simulator.

Guest iep Posted October 24, 2007 Report Share Posted October 24, 2007 there are actually a few lateral-flux capacitors in there... still, nothing that would make you travel through time when accelerated to 88mph!

Bubba69 Posted October 26, 2007 Report Share Posted October 26, 2007 awesome. But im not sure this qualifies as polyphonic, seems more like multi-voiced.
