VC-Swing (was: sequencer meanderings)

[List, Christopher]

The 909 implements swing by delaying every _even_ step by some amount
(proportional to the swing setting). - That's all there is to it. 909-style
swing could be implemented in an analog sequencer with some sort of VC-able
clock delay type circuit. If the sequencer has an internal clock, you could
use a triangle osc. for the clock (as opposed to the usual saw wave) and
have knobs for setting the "on" trigger level for the step logic. Using an
external clock gets a little trickier, as you need to be able to vary the
number of clock ticks per step - both for the start and the stop of the
note. It would also be up to you whether you'd want to be able to set the
delay for each step, or have one big rotary switch that sets it for all even
steps, while all odd steps are fixed (like the 909). It could be a fun
project to work it out in hardware.
