What you get is kind of a Barber-Pole scale, but I can definitly recognise the roots. I tried it both starting on the root and ending on the root, and starting on the root and ending on the 7th, in the Major, Minor, and Minor Harmonic Scales. What does seem to work is simply to use at least 4 seperate voices to gernerate independent, evenly spaced tones with increasing frequency. When a voice reaches an upper bound (the higher the better) set it back to something under 40hz. Also, non-linear (increasing) functions of freq. vs time seem to work better, but the programmablity of the synth hindered me from better exploration of possible functions. Both of these sounds are intersting. If I ever decide to learn to program the audio portion of the Amiga maybe I'll writeup a quicky demo of these effects. Thanks, Wade.
