        Nic,

                I tried this, on a programmable synth, and it don't work. 
             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.
