MS-20 Mini tune and scale adjustment

I sometimes have to re-tune my MS-20 Mini. The pitch scaling is incorrect, and has to be adjusted. Sometimes on both oscillators. To do this I set up a tuner next to the speaker and start playing octaves. I turn the scale trim pot until the octaves are clean, and then I move it to the correct base pitch with the tune trim pot.

Usually I just poke at the trimpots until I find the correct ones but the last time I did this I wrote the numbers down:

PT3 - tune osc1
PT1 - scale osc1
PT5 - tune osc2
PT4 - scale osc2

The trim pots are located on the back of the board that sits under the panel and are easily accessible by just removing the back panel.
