OK, I was able to do that... but it took me a fair number of modules.
Maybe there's a simpler way?
The first problem is, except for the TKB, you don't have stage-select
outputs, so you have to arrange to get that signal somehow. I chained
my TKB to a 4-stage programmer. I used the stage select output (#16)
from the TKB, and I used row B of the programmer to get the equivalent:
set all the B knobs but stage 4 full left, and stage 4 full right. Then
the B output is effectively the stage select out.
Now, hooking them together... start with the ASR toggle flip-flop patch
from my last post. That's going to control which sequencer is running.
Now patch:
--------
ASR output 1 -> ACPR vc xfade
seq. 1 A output -> ACPR in 1
seq. 2 A output -> ACPR in 2
ACPR out -> output signal
ASR output 1 -> seq. 1 hold
ASR output 2 -> seq. 2 hold
seq. 1 stage-select out -> DTG #1 trig in (set rise full right, fall
almost full-right)
seq. 2 stage-select out -> DTG #2 trig in (set rise full right, fall
almost full-right)
DTG #1 output -> OR in A
DTG #2 output -> OR in B
OR out -> ASR pulse in
overall clock -> seq. 1 clock & seq. 2 clock
--------
The DTGs (or DSGs) are used to turn the stage-select out gates into
pulses. (Otherwise one is always on, and the OR output stays high, and
doesn't generate pulses.) Any other way you want to turn gates into
pulses will also work fine. Also, you could just use a processor
instead of the OR to add the pulse signals.
Cheers,
Bob

morning it came to me that this might be a way to get that "set, reset"
thing going on. But i didn't know how to go about it even though i
spent some time working on it in my head. I won't have time to get to
the machine till next wee 'cause of daughters school activities this
weekend.But it would seem to me the ASR approach would be the simplest.
Along these same lines, instead of , or along with useing Row A and Row
B to double the length of the sequencer, how about running two in
serial? Last stage "gate out" of first Seq starts the second
sequencer. But how to "hold" the first while the second runs, and then
"reset" and "hold"the second while the first one is "reset" and started
again. I'v been thinking on this for months and haven't been able to
execute the procedure. Anyone?
