I'm experiencing timing issues on the HXFX 3.15; Tempo of Tremolo doesn't match the midi clock. in Helix Posted June 3 On 6/2/2022 at 9:53 PM, Klydelovell said: Was it via a midi cable? It may be jitter, which I hope not, but the other device listening to the source (which is a Circuit Tracks) is an MC101, and it seems to be fine. That said, maybe the 101 is really accepting, I'll have to do some experiments, because my RC202 can't take jitter from the Circuit Tracks. That said, I've asked people more knowledgeable than me if the Tracks has jitter, and I've gotten that *if* it does, it's .1, maybe .2 off. The test I did between zoia and stomp was via two WIDI master, and really worked. I even tried with no subdivisions (1/1), and tremolo was pulsing in sync with blue flashing. Also tried setting a delay in the zoia clocked togheter with the Stomp tremolo, and they were locked properly. Of course this wont help you much as your setup is different, but imho that is how it should behave. As for the jitter, I remember getting problems with some hardware that I tried to use as clock source (via midi cable this time), and that Helix didnt manage to follow...but in that case I remember the blue flashing was clearly off and erratic (sometimes even flashing red in between blue, which means disconnections from the clock).
