a 16 steps sequencer (maybe 32 steps).<br>
So far I'd have 2 choices for the final number of steps CV adjustments.<br>
<br>
- Standard CV pots sequenced with gates<br>
pros: cost is cheap, the note value is physicaly kept by each pots<br>
cons: bad note precision on large span (I'd like a 61 notes span on each<br>
CV adj),<br>
span must be kept not too large..<br>
<br>
- Rotary encoders<br>
pros: Very large CV span can be achieved on each steps (beyond 61 notes), <br>
quantization easy to be achieved on each steps adjustments. <br>
cons: expensive (are they all ?), need for data memory to keep every note<br>
values (micro-processor needed)<br>
<br>
All the gates could be generated by the same micro or<br>
from a precise adjustable master clock<br>
<br>
What do you think from your past experiences ?<br>
