* My FH-2 is using the USB-C to my Mac, which is running Ableton (or Bitwig). I have the DAW send the MIDI clock + start/stop.
* My FH-2 port 1 output is set to to Clock and 24ppm and port 2 is "Start only". These go into the clock/reset on the Circadian Rhythms.
* From the Circadian I got a trigger pulse on 1/8th that I sample straight back into the DAW to see how the clock aligns up with the bars in the DAW.
What I observe is that _sometimes_ the clock works out fine, and the sampled pulse aligns with the beat, but most times it doesn't and the Circadian ends up ~21ms behind at 120bpm, and roughly 16ms at 150bpm. The timings seem to indicate that it's behind exactly one PPM (60/120/24=21ms and 60/150/24=16).
I've tried using 16th clock instead of 24ppm, and the circadian "DIN" option, which is some support mode for old Roland gear. I've fiddled with the midi clock delay timings in the DAW, and nothing fixes it.
I also had similar problems in the past, and the one reliable combo I found was using the ES-9 + TMB and then TRS MIDI to uQMCV, which in turn provided a 16th clock + run signal.
Obviously the reset needs to be sent some microseconds before the clock pulse, and the only thing I can think of is that the offset FH-2 uses between the reset and clock is either too big or too small for Circadian Rhythms.
Is there a way I can change this offset?
Anything else I should try?
(Yeah, I know about using a WAV clock pulse and/or Silent Way, I'm more interested in the MIDI clock route)
