it took a bit of fiddling around to see what was meant about 'digital cross-modulation'-i'll have to check again- but it's mainly a bonus on that synth, to have the extras. (it's quite an impressive little thing)
is 'blep' a term for bandlimiting? i've tried generating saws and squares as 'naive' waveforms, and it was ok but you do get aliasing on high notes in some situations. (is not too much of a problem?) supposedly you'd have progressive bandlimiting as pitch rises, is that it? i was suprised and a bit disappointed that DSP oscillators are often wavetables with (?look-up tables? i'm not a programmer)
