I have a Mod Rex and a Super Pulsar which I have been struggling to synch with a Zoom R24 for a couple of years (there is another thread about that but mainly related to the Super Pulsar).
Recently, I found a device which converts a metronome audio signal to a clock pulse and all was well until I tried to synch to a 40bpm (the slowest rate the Zoom R24 will go) pulse in order to create a whole note sweeping phase effect but the Mod-Rex doesn’t seem to be able to synch at such a slow rate. It can be manually set at 30bpm, so it isn’t outside technical specifications but the rate is erratic when the clock in is lower than about 80bpm. Super Pulsar synchs without problem and I have tried swapping the synch connections and the Super Pulsar synchs but the Mod-Rex does not.
Is there a technical treason for this?

I will also pass this on to the designer.May 16, 2022 at 11:12 am #190863OkuloParticipantSorry, they haven’t answered mine.
I have checked my spam folder. Maybe they should check theirs.

There is a minimum BPM for the tap-tempo and that minimum is technically the same for an external pulse (which can also be an external tap). This minimum is about 2 seconds, as in if more than 2 seconds go by after a tap it just forgets about it and expects the next tap to be the first of a new tap-tempo set. This limit is done to allow people to tap in new tempos without it getting caught up on the last tap if it was “too long ago”. But also the way the debounce works it becomes increasingly unreliable at very low tempos. MIDI Clock may work with the Mod Rex at lower tempos like that. Also, depending on what they’re trying to do, they could double the tempo (so 80bpm instead of 40) and cut the division for each modulation their going for in half.
