[sdiy] DIY Moog 960 Sequencer

[Stewart Pye]

I'm building a sequencer based on the operation of the Moog 960, but 
using an AVR microcontroller to do all the shifting and control, with a 
precision DAC for a quantised CV output.

 From the Moog schematic it looks like the IN socket and the SET switch 
for each step cause the sequencer to jump to that step immediately.

I don't have all the switches or the DAC hooked up yet, but I thought it 
would be better to have the SET switch action wait until it got the next 
trigger pulse. That way as the sequence is playing you can manually 
select a step without screwing up the timing. From my understanding of 
the circuit that would have added a bit of complexity to the Moog 
design, but with a micro it will be easy.

Can anyone confirm that the Moog circuit does perform the way I assumed 
above, and does the method I plan to use make sense from an operation 
point of view? I've just got a few pots and switches hanging off my AVR 
development board at the moment so it's a bit hard to tell!

Regards,
Stewart.
