One simple but useful modification I did to mine was to hack external 
jack inputs into the mod panel. I have two jacks on the back that 
replace the Filter Envelope and Osc B modulations when you stick 
something in.

I'd also recommend being able to clock the sequencer independently of 
the LFO (The Gate In will do this, but maybe add a dedicated square 
wave clock for the job), and perhaps if you have MIDI, you might want 
to be able to sync the sequencer to the MIDI clock, or use the hard 
sync input on the LFO chip to sync that to the MIDI clock.

Finally, a Pro-One is about 24" wide, so you've got to get rid of 5" to 
fit it in a rack. Given that the main PCB also has all the controls, 
I'm not clear how you're going to pull this stunt off. You're a braver 
man than I if you go for it.
