Hi, I am seeing some glitches in the CV output of my uTune. It does not happen all the time, but it does happen many times during any run.
Here is what I mean: I will hear a pitch “yodel” between two adjacent values, and when this happens, I can see it changing rapidly on the status page. For example, one of the channel will rapidly switch back and forth between 5 and 6. I am in free-running mode (CV in only, no gate input).
I am getting the CV input from the CV output of a Make Noise Rene. If I take the CV output from the Rene and bypass the uTune so that I’m using the un-quantized values, I do not observe this glitching, which is why I believe that it is happening in the uTune.
Is this perhaps a calibration issue? What is the procedure to calibrate the uTune with firmware 1.11 and HW 18?
Some further evidence. I compared the Rene output CV to the uTune output CV on the corresponding channel by running them both through a scope (O’Toole+). I observed that when the uTune output glitched, the Rene output remained steady.
Woo-hoo!!! FW 1.12 has solved the MIDI problems I was having — the module no longer locks up, and I’m finally getting proper MIDI output! Very happy about this, as now I can ditch the Doepfer A-192-2 and free up space for another module.
The glitching also seems to be gone, but I’m not 100% sure yet because it’s intermittent. So I will continue to let things run and keep an eye on it.
