I'm noticing some strangeness when clocking the ARP externally.
Setup:
Clock in from Cirklon 2 via USB port - always running, whether MIDI start/stop has been sent or not.
ARP - slaved to clock, shows correct tempo flickering slightly +/- 1 (I assume USB jitter here).
ARP has 4 patterns unmuted.
When I hit "play" on the Cirklon, everything works perfectly. All arps play the expected tempo/notes in synch at correct speed.
However, when I hit "stop" on the Cirklon (sends MIDI STOP message to ARP, ARP stops) and then hit "play" on the ARP to test the arpeggios while I'm tweaking them (remember, the MIDI clock itself hasn't stopped here), the ARP does one of the following, somewhat randomly (though most often the first example), and switches between them randomly when I pause and play again:
Plays only the first "arp" sequence, at what feels like twice the speed, but rather "jerkily" and drops a lot of note messages so I get a sort of funky randomly fading / phasing pattern based on dropped notes and odd durations.
Plays all four sequences at double-or-more speed like a drunken madman (somewhat jittery and not all in sync - or so it feels, at least, it's too fast to note what's actually going on)
Plays nothing, but has the play button green and enabled, and acts like it's playing something (measure bar indicator in OLED advances "normally")
Bit odd, this. I'm on firmware 1.5.5.3972.
Any update on this? I'm not sure if it's the same issue, but I'm getting lots of clock jitter when I'm trying to connect with ableton. My preferred setup is Ableton -> MRC (Midi Router) -> CAKE but it is also reproducible if I go direct Ableton -> CAKE, I would also prefer to stick with just usb, but in my search I also tested via midi-in with similar results
Normally it's a decimal or two, but on ableton sometimes it gets into a scenario where it predictably jumps something like 30 or more bpm. It appears to do this relatively consistently and maybe appears more when ableton sends notes out alongside the clock. It's possible these notes aren't perfectly timed to a downbeat if that's relevant 120 - this bpm tends to work jitter free in most scenarios, 90 as well. Others are almost all some level of jitter Is there any sort of recommended method to handle this stuff? Or a most optimum setup that would help the arp really lock in?
Cheers for that Chris, I'll leave it in your capable hands!
I'll note too that this also happens before I send any MIDI commands. If clock is just running and the ARP boots up, for instance, it'll right away be in this weird mode too. Likely the same internal state situation, if I understand what you're describing properly.
Cheers for reporting this.
I wonder if this is due to ARP thinking it doesn't have an external clock, after stop is sent, it is then enabling its own internal clock. It would explain the random because the tick will be running at irregular intervals. This is not by design.
I did a load of work around this back last summer so was pretty confident, but there were some tweaks made during beta for v5.
Leave it with me and I'll try to replicate the issue.
