Just tested (again) all PPQN settings with various midi clock speeds.
Which program are you using to send the midi clock?
How did you test for the correctness of the settings? oscilloscope? Or do you verify with a drum machine? In the latter case I can imagine a drum machine might skip clock pulses in certain conditions..
I am sending MIDI clock from Cubase AI 6 and looking at the uniPulse outputs on an oscilloscope. On oscilloscope ch 1 I’m monitoring and triggering on D1 and on ch2 I’m monitoring P1. Neither output is loaded (except for the scope probe). D1 is configured as Sync Clock and P1 as Sync Pulse. I select the same PPQN for both, upload it, start the MIDI clock, and compare upper and lower traces. D1 is correct for all the PPQN I’ve tested, but P1 is behaving as I documented above.
And here is my scope snapshot of the uniPulse outputs D1 and P1 when driven by Cubase running at 60 bpm. The upper trace is D1 and the lower is P1. 1/12 ~= 0.083 and that’s what the upper trace shows as the period, but the lower trace shows pulses on every D1 transition, i.e. 24 PPQN.
Hello Tubbutec, I see that some more development is currently going, great thing ! Any chance that you could also fix the 66 arp issue in up/down mode that has been reported a few months ago ? The 66 community will thank you !
I could test this if needed
