I always thought it would be fun to have a 4 channel looper that could loop the VCO CV, 
wave CV, filter CV and VCA CV. That way when you play a neat little lick, you could hit 
"loop" and then have you hands free to twiddle the knobs.

For Tangerine Dream kind of days (they did a lot of knob twiddling over sequences that 
sound real good).

The old ARP 1603 would do 4 bars of 4/4 (16) so only 16 to 32 actual notes need to be 
stored. I saw pictures of them using 1603s and 2600s at some point.

Just a thought.
