I’ve recently built 4 of the 1222 modules, but unfortunately I’m finding them very difficult to use due to the tuning drifting constantly.
Here are the various issues I’ve got with them:
After playing them for just a few seconds, the tuning is often out by a semitone or more. I would play the same sequence of notes and you can hear it shift rapidly.
The general tuning seem to drift over time as well, over the course of one hour, it would gradually go up in pitch, maybe a semi tone every 5min or so up to 4 semi-tones.
I’m not sure how accurate the in-built tuner is but it can not stay stable, the leds would go from red to green to red multiple times per second. Which I’m guessing would have something to do with the overall tuning being unstable
I find that I have to re-calibrate the center note every time i use them.
I’ve changed R42 for 1k, and the problem seem to occur regardless of the waveform. All of them have the same problem too
I’m wondering if anyone has had similar issues and if they have managed to fix them?
