Calibration difficulties - overly sensitive trimmer? #196

Open someot opened 1 year ago

someot commented 1 year ago

I've been having significant difficulties with my Turing Machine Mk. 2, all around calibration. I built it myself and I would consider myself a DIY novice, so build error is possible.

When I calibrate, it feels as if my trimmer is incredibly sensitive. I can trim to a stable tone, but the act of simply letting go of the screwdriver (while it is still inserted into the trimmer) will change the calibration. Because of this, it's been near impossible to actually get full usage out of the lock/unlock knob. I've gotten close, but most of the time it's only able to be full locked or full unlocked, with nothing in between.

Sam I would consider dialling back a little bit from the 'perfect' calibration (assuming you are following the video guide).

A lot of the time this will still lock absolutely fine in a normal range of clock tempos and use cases. Don't get too hooked up on the perfect calibration and see where you get to in normal use, using your ears, that still locks on either side for all normal sequencer purposes and Is random at midnight and then with some mix of the two inbetween.
