Buchla/TTA 245t Pulser Sync and 257t RM/AM

Modwiggler member "luketeaford" posted regarding 245t Pulser sync (using the "ref out" to ping the Optomix) method:
"Syncing Pulser
This works by starting and stopping the pulser. Use your sync signal to start the pulser-- let's say it's a pulse out from another pulser. Patch the pulse out also to trig in on a 281t. Use the end of cycle pulse output from the 281t to stop the sequence. I set attack and decay to 0. Tune the pulser you're syncing so that during the brief ON period one cycle happens. Faster will give you clock multiples, slower will give you clock divisions. Modulating the 281t function time will give you ratcheting. This is easiest to do with trigs only and 0 length pulsers and then tune to use sustained function and variable length pulses."

If you want to reset the 245t you can send a reset to which ever Stage Select Input you want to reset from.

Patch for RM/AM is simply inverting the waveform of the top 258t VCO using the top half of the 257t and adding that output to one side of the crossfader circuit on the bottom 257t, whereas the input of the other side is the non inverted version of the top 258t VCO waveform.

The bottom 258t VCO is the crossfader CV input.
When the crossfader knob is at noon, the result is crossfading from the inverted to the non inverted waveform at audio rate the fundamental is cancelled out yielding ring modulation.
When the crossfader knob is at either CCW or CW position, the fundamental is present yielding amplitude modulation.

FX are Clouds (Granular mode) and Z-DSP (Halls of Valhalla).
