MOTM

I've just finished an experiment of using two Frequency Shifters to turn a
Fixed Filter Bank
into something animated, modulated.

 A drone sound from the OB-8 is sent to a first Frequency Shifter, which
shifts the audio signal up by a variable amount of Hz.

This upshifted signal is sent thru a filter bank (MAM vocoder, with a rather
thin-sounding setting with all even channels up and all odd channels down.

This filtered signal is shifted back down with a second Frequency Shifter,
by the same amount of Hz that the original signal was shifted up.

First you hear the very thin sounding unshifted signal - just the OB-8 drone
processd by the vocoder filter bank.

Then we start to modulate the Frequency Shifter with the Joystick.

mp3, but it was no good)

Please note that there is no filter modulation! The filter is fixed all the
time (static formant filter) - it's the signal that is modulated!

Sorry for the rather low quality of the unmodulated sound - I just made this
experiment at 1 am after
finishing the hardware. :)

Let me know if you have ideas what else could be processed with this. I'll
certainly try reverb, and all
kinds of fixed filters.
