Hello, maybe this isn't possible, but I wanted to post on here just in case. I have a MFB-522 Drumcomputer, it only has MIDI in and I'm trying to clock/trigger it with the DX looper (or even LFO if that could happen). I've updated firmware to 1.3. I've made sure both units are on the same MIDI channel. Usually I trigger the 522 with a sequencer or arpeggiator on another hardware synth I own. When the arp or sequence starts, the 522 starts it's sequence. I figured maybe when a quantized loop starts, it might trigger the 522, but nothing happens. So, if anyone has any ideas, I'd love to hear them.
Should work fine with the looper at least. I'd love to see BPM-sync and the ability to remove the key trigger on the LFO for this little guy... Maybe we can beg Yamaha to do another update.
Anyway, I just tested this with my Reface DX and Roland TR-626 and it works as expected.
Set the TR-626 to sync to MIDI clock, connected it's MIDI IN jack to the MIDI OUT jack on the Reface DX's break-out cable.
Set the BPM on the looper, and make sure you don't have anything hooked to it's MIDI IN that's transmitting a clock or it'll automatically switch to external sync.
Drums start and stop when I start/stop the looper. The only annoying thing is when you first record the loop, after you press stop, it will re-start playing the loop out of sync with the drums. Stop/start again solves that.
