Hello,
You may use Tempo Sync for the preset to sync to the H90’s Tempo (or MIDI clock).
If Tempo Sync is OFF, you can use the “Tap” perform parameter to tap the tempo in for your preset, while not following the H90’s tempo/MIDI clock.
This is explained in the section of the user manual below, but let me know if you need further explanation or help setting this up:
