Output calibration?

Bug Reports and Fixes
1

I have noticed that the Meta Module output drifts a bit with 1 v/oct input. Using the Keystep Pro pitch cv out gets the following:
Input (V)____ Output from MM (V):
0 ___________ 0.01
1 ___________ 1.02
2 ___________ 2.05
3 ___________ 3.07
4 ___________ 4.10
5 ___________ 5.12

I patched the cable in directly to the out and measured both in and out. Did the same using a quantizer in between (in MM) and got the same outcome. Checked the calibration, but cant seem to find calibration of outputs…

I also have trouble with the audio expander. No matter what I connect to the inputs it has different (static) values. Tried to calibrated it to no avail. Next step is to check the connection… The static values are:
Input 7. 0.016 V
Input 8. -0.007 V
Input 9. 0.021 V
Input 10. 0.004 V
Input 11. -0.001 V
Input 12. -0.012 V

I detached the cables for the audio expander and retached them - seems like there was a glitch and now it is working as intended… The output calibration persists though…

That definitely can be fixed with calibration, as the response is very linear (I’m eyeballing that at ~1.025V/oct).
I recommend re-calibrating using the KeyStep Pro. The output calibration step happens after the inputs (you just have to go through the whole process until it says it saved the results).

For checking the output calibration, while the inputs display their values on screen the outputs are just outputting integer voltages. Turn Knob A to set a new voltage. E.g. measure the voltage on Out 1, and you should get 1.00V, 2.00V, 3.00V, etc as you turn Knob A up.

And it’s important to let the MetaModule warm up before calibrating. Make sure it’s been on for at least 5 minutes before performing or checking calibration.
