Re: Sequencer (gate, maybe)

2007-07-09 by synthwick

I was going to build one gate seq. and have two switch boards on it (4
rows), but have now decided to build 2 complete gate sequencers (w/
the gates and CV's on each) and that way I can run each off a
different division of the clock if I want.

It was tough to decide between the seq. switch or the gate seq. I may
have to eventually build the seq. switch, because I would like the
ability to.. well.. sequentially switch things :).

There's one thing I want to do and I don't know the best way to go
about it. Say I have the VCO being fed from a sample/hold and it's
playing it's little tune. I want to be able to change the octave for
say 4 measures, then back down for four, then up again.
I was thinking about the analog switch (cgs55), but Im not sure how
the switch works. Does it switch on w/ a pulse, then back off w/
another pulse, or does it switch on while it has a gate, then back off
when the gate is removed? (I'd feed 1v into the input of the switch,
send a division of the clock to the switch to turn it on and off....
if the switch works in that way)

If that doesn't work, my next idea was to use the sequential switch,
but that would be much less efficient. (as far as parts needed, and
patching complexity)

Am I on the right track with that? I'd also like to use it to switch
on and off triggers going to percussion at different times, but still
in time with the clock, etc.
As soon as I found Ken's work and began to understand it, my interest
in my synth quickly changed from the sounds it can make, to the ways I
can automate it.
