[music-dsp] Fw: A little question about DSP performance

quite difficult to isolate (in listening conditions) a particular phase 
shifted harmonic as the difference between two saw-waves (which are 
harmonicly rich waveforms)
here is the same method didier described but with phase inversion in the end 
between the two (1,3)

note: sorry, but my generator is a bit noisy (around -80dbfs)
- sytrus seems like a nice synth btw. good work there.

i'd suggest the above hosting service - dropbox. it has shell integration 
and can be used for sharing files between developers in the lines of copy 
pasting in folders and direct linking. i don't have the shell version but 
the web interface is also quite good.
