[LAD] Xsynth-DSSI experimental hack

Hi all, In keeping with the usual Xsynth-DSSI hackery I like to do (since it makes such an awesome experimental base) I'd like to present my latest horrible unlistenable noise generator: http://www.gjcp.net/~gordonjcp/xsynthhack.ogg Warning: only the voice generation code has been changed. This will overwrite or otherwise badly affect an existing install of Xsynth-DSSI. Be careful! http://www.gjcp.net/~gordonjcp/xsynth-dssi-0.9.4.tar.gz So what's different about it? Well, the minblep band-limited oscillators have been replaced by Tomisawa sine-feedback oscillators. These resemble "operator 4" in a DX21 or other four-op FM synth, in that by applying FM feedback around a sine function it starts to approximate a sawtooth wave. If you take two sawtooth waves, offset the phases, and subtract, you get a squarewave. By varying the offset, you vary the pulsewidth. Now here's the clever bit - I've modified things slightly so that the two Tomisawa generators can run at different speeds. So, by offsetting the frequencies you get either a deep PWM squarewave or a kind of "supersaw"-type sound. By varying the amount of modulation (beta) you can determine the "shape" of the waveform. So how are the oscillator controls affected? Pitch remains the same. Waveshapes are Sine (as you'd expect), Tri (saw with not much beta, really), Saw up and down are both just saw, Square (adjustable pulsewidth), Square with adjustable drift, and Saw with adjustable drift. Pitch mod and sync don't currently work. I don't know if sync can be made to work, without introducing aliasing. Have a play and let me know how you get on. Gordon MM0YEQ
