The audiowerkstatt midi-clock-multiplier multiplies the MIDI-clock of the MIDI-master, whereby the MIDI-slave runs correspondingly faster. The multipliers are 1x, 2x, 3x, ..., 8x, 9x.
If the multiplier 1 is selected, the MIDI-clock is simply passed through. With the multiplier of e.g. 2 the MIDI-slave runs at double speed. So 16ths-notes will be 32th-notes.
Very useful if you have a very slow song and want to add a new fast track to it, which is faster than the master-clock.
And good for polyrhythmik - especially for experimental musicians - if an odd division-factor is selected and MIDI-master and slave seem to be not in sync, but from time to time come together in perfect sync.
You can also set whether only the newly created MIDI-clock and mmc commands (start, stop, continue) are sent or the, at the MIDI-in incoming data, will be mixed with that.
