I'm interested in using cycle~ to play back basic synthesis waveform shapes (saw, triangle, etc), but I don't have the chops to generate 16k sample sound files to use as a buffer in cycle~. Are these files floating around out there?
Also you can use poly~ to wrap the appropriate oscillators and call them on demand, which will give superior sound quality, especially for waves like sawtooth, which have tons of high partials. If you do it with a wavetable, your wave will either be way too dark, or super-aliased...
Check the poly~ helpfile under the "dynamic polyphony" tab for more details.
