The situation is a setup for live playing, I want to sync my VCV Rack patch with other things running at the same tempo. In the studio I can use midi pulses in various ways to do that, tweaking to account for latency but playing live that’s a bit fiddly and likely to go wrong.
In the patch, I’ve got run and reset buttons triggered from midi pads or clicking with the mouse. That’s OK and gets it roughly right. I’m a drummer so I’d hope my time isn’t so bad, but hitting a rubbery pad isn’t the same as hitting a drum and it’s hard to get spot on. Also as a drummer, I know that ‘spot on’ isn’t always ‘right’, musically you sometimes want a bit of advance / drag of the beat depending on the musical style.
The obvious method of turning the tempo knob directly doesn’t work well in practice as it’s too sensitive.
My workaround is in the screenshot below, I can momentarily connect tweaked CVs to the BPM input of Impromptu’s Clcoked, to slightly speed up or slow down the clock tempo and feel into into place, then disconnect the cable when it’s good. I’ve use a sample-and-hold to pick up the original tempo CV and attenuverters to offset the voltage slightly, so I can use it at any tempo without getting the calculator out.
It works, but seems a bit overkill - is there some more elegant way to advance/retard the clock or even better keep it at the same tempo but nudge it forward/backward?
