clocking S2400 via analog in (clock speed set to 16ths) via Ableton using an ERM multiclock which outputs analog clock, everything works solid. I change bpm on Ableton, S2400 syncs to same tempo.
but as soon as I plug a usb cable out from S2400 USB B port to enable audio over usb on my Mac, clock triples in speed and not an exact multiplication. goes from 100 bpm to 410 bpm.
I had this exact set up working a few days ago, clock speed was set to 16ths on the Isla and was locking no problem and using usb over audio to record.
I’ve since tried every clock setting but nothing syncs correctly when usb lead is plugged in. I’ve unchecked all the boxes on the USB sync settings, but still no joy.
if I use the ERM to sync via midi with USB cable plugged in, Isla again, syncs no problem.
Ok. Can you remember if Ableton was set to send MIDI Clock to the S2400? S2400 shouldn’t be able to sync to two clocks at the same time, but I’m wondering if somehow it was.
I’m unable to check as it was so long ago, but my working method is to never sync using midi from Ableton. I always use an audio signal from my DAW into the analog clock-in of my ERM Multiclock and clock out or midi out form the multi clock. I can try and sync tomorrow.
I have a similar problem. Although my clock goes from set BPM to logarithmic crash into infinity. I have posts about the details on this forum. But here’s the short version and latest news.
I first encountered the problem when allowing the Moog Subharmonicon to control the S2400 clock. Thank god for backups as it somehow permanently stains itself into the SD Card where I need to wipe the whole thing to stop it from happening. Granted it only happens when I set the S2400 back to internal clock, everything can run smoothly by using the shift+play option, but I don’t like a 99% functional instrument.
Second device that I ran into to cause this was messing with every iteration of MIDI control and clock settings with Logic, this didn’t bother me too badly.
Until yesterday when experimenting with every iteration of daisy chaining to have the S2400 be the brain of everything. I have a Vermona drm1, prophet rev2, Korg Minilogue XD, Moog Minitaur, Synthstrom deluge (which I use as a sequencer mostly), and a 280HP modular set up with the Subharmonicon in it (amongst other devices which need CV control from the deluge).
Well I figured why not plug the deluge into the USB-Host jack, and it worked wonders. Until I went to power off the S2400 and it only KIND OF powered off, dimmed lights, flashed an error message. So I unplugged the deluge and powered off and it didn’t happen again. So I figured it must be the messages being sent back and forth, then checked PPQN, and the original BPM speed up into infinity happened again, but this time wasn’t permanent.
I’m getting a midi thru box. And that’s just gonna solve everything.
