Hello,
I'm having some challenge with the 2S&H and the SEQ16. I like to use the S&H to sample pitch CV from the SEQ16, using the TRIQ164 as a trigger. However, it seems that the S&H is too fast, I often end up sampling the pitch from the step before. Is there an easy way of delaying the sampling of even just a couple of milliseconds ? I could use the 2ENV to delay the trigger, but they are often all taken.
Thanks !

I think you already thought about using one env for 2 things.
Maybe the divider could work somehow but needs always a second trigger?

seems like a good idea. i might try it tonight!
in my mind it would work like this:
seq cv out >>> s&h input
square lfo out >>> s&h trigger input
the lfo would set the rate.

whoops I see you want to use triq as your trigger. it could be that you have the repeat setting too high?

Some of this should get dealt with when Robert introduces the TRIP, which has some trigger delay functions. That should be useful for using the 2S&H as a two-position shift register, also.

If you have the logic module you could try to invert the TRIG164 pulse that triggers the S&H. Depending on the pulse width this may “shift” the triggers enough to come after the SEQ16 step.
Another possibility would be to use AND logic, if the TRIG164 pulse overlaps the SEQ16 pulse. By using AND a gate would only be generated when both sequencers are high, so only when the SEQ16 is at the next step (since it’s happening after the rising edge of the TRIG164).
Like this:
TRIG164: _____———____
SEQ16: ________———____
AND: __________——____
Edit:
Yet another way using the logic module:
Make the TRIG164 reset a square LFO. This should start it HIGH, so the first LFO HIGH aligns with the TRIG‘s pulse. Invert the LFO square wave then (making it start LOW) and then set the LFO speed to something just a little bit slower than the TRIG frequency and also use the LFO’s pulse width control to dial in the trigger delay precisely.

Ha actually I had the same idea with ANDing the TRIQ trigger and SEQ gate before I read your post, and it is working well enough ! Thanks for all the suggestions, lots of food for thought.
