Here’s another example of manually applying subharmonic frequencies to a musical phrase. I used the Bitstream 3X arpeggiator to drive the Roland MKS-80 then duplicated the track. On the second track I dropped the frequency by twelve semi-tones and ran it through a low-pass filter effectively eliminating upper harmonics and creating subharmonic frequencies based on the original piece. Although this technique sounds good, it’s not exactly practical, so soon I repeat the experiments with some processors that are designed specifically to do this.
