Type a tempo, from 20 to 300 BPM, or click Tap in time.
The dot next to BPM flashes on each beat.
Under Clock from, you can follow a MIDI clock. Modulate then uses the clock’s tempo, start, stop and position. By default it listens on its own MIDI input, called “WaveStack Modulate”. When the clock stops, Modulate goes back to its own tempo.
You can also follow a clock on an interface input. See Clock in.
Restart starts every source from the beginning of its cycle, all at once.
