These are both patches I put together in response to a question that Michael Eidt asked in the Facebook group about recreating the Zoom trigger hold delay. The idea of the delay is that when the delay is triggered by incoming audio, it will capture incoming sound for a period determined by tap tempo and hold it in its buffer until triggered again.
One — ‘trig loop’ — uses a looper, the other — ‘trig delay’ — a delay line to achieve (hopefully) similar results. The delay line is more reliable (rock solid stuff); the looper is more flexible but occasionally does ****ing looper **** that makes you want to tear your ****ing hair out.
The first page of each is the triggering device (onset detector w/ sensitivity enabled; look here if you want to adjust the sensitivity of the circuit) and timing device (an AHD envelope — the middle one, to be precise; the other two are there to improve the performance by cleaning up the signal from the onset detector and providing redundancies to discourage retriggers). The length of the hold stage — the actual time-keeper of the patch — is set by tap (left stompswitch), via a tap-to-CV converter. (These patches require firmware 1.13 to function properly.)
The second page is the audio engine; for trig loop, the loopers, for trig delay the delay lines and VCAs. They are controlled by modules on the first page.
The third page is the tap tempo and tap-to-CV conversion. There is also a clock divider because I have trouble tapping in the really short glitchy bursts, personally, so setting this to 2x or 3x helps me.
Tap tempo is set by the left stompswitch.
On the ‘trig loop’ patch, the middle stompswitch (latching) will double the speed/pitch of the loop, raising it an octave, and the right stompswitch (latching) will drop the speed to half, lowering it an octave and reverse the loop (and the combination of the two stompswitches will result in the loop playing at normal speed but in reverse). The stompswitch controls are on the same page as the loopers.
The patches are stereo throughout, but they could easily be made mono, and they will work in mono. The onset detector is triggered from the left input.
No demo. We’ll see where this goes.
