Wrong pitch information shown for steps without PTC lock

[unekinn]

Steps to reproduce

1. Use a tonal sound, set pitch to 0 on the Machinedrum
2. In an empty pattern, enter "Step edit" on MCL
3. Place two trigs
4. Parameter lock PTC on the first trig to C0
5. Press play and hear two different pitches for the two trigs
6. Hold the second trig, but don't parameter lock anything. Notice that the PTC still says C0, even though the second trig's pitch hasn't changed
7. Place a third trig. Notice that PTC still says C0 on the MCL, even if the sounding pitch is not C0.
8. Parameter lock the second trig to e.g. E0
9. Hold the third trig, but don't parameter lock. PTC now erroneously says E0
10. Hold the first trig, PTC correctly says C0
11. Hold the third trig, PTC now erroneously says E0

This seems to happen whether or not you've placed locks on other parameters than PTC.

(Maybe related: When placing a new trig, the PTC from the previously locked step will show up and stay on screen even after releasing the trig. You can turn the encoder to change the PTC value, but nothing will actually change.)

Actual result

If there's no PTC lock for a trig, it will show the pitch info for the previously "held" trig with an actual PTC lock.

Expected result

Trigs without at PTC lock should show --, or possibly the note value corresponding to the non-locked pitch for the sound on the Machinedrum.

Placing a new trig should not cause PTC to stay on-screen and be editable (with no actual result) after releasing the trig

Thanks will chase this down.
