Close the enclosure and adjust the key action
7 steps
Inspect the internal alignment
With power off, check that the PCB, keys and key-mount rail are correctly seated. Confirm loose wires stay out of the case joint.
Check: No key is held against its switch before the enclosure closes.

Join the case halves
Align the enclosure top and bottom and snap them together while keeping the rail and keys in position.
Check: The joint closes evenly and the keys remain aligned.
Run the first key check
Switch on at a modest volume and press each key. Listen for any note that sounds without a deliberate key press.
Check: No note is continuously triggered at rest.
Fit the volume knob
Switch off while positioning the knob. Match the knob dimple to the marker on the potentiometer shaft and press the knob into place.
Check: The knob sits securely and rotates without scraping the case.
Insert the two screws
Pass the machine screws upward through the enclosure bottom. If they do not enter cleanly, reopen and correct the PCB, rail and key alignment.
Check: Both screws engage without forcing misaligned internal parts.
Balance the key action
With the synth on and silent at rest, tighten the screws gradually. If a note begins sounding, back off that screw until it stops.
Check: The screws hold the case while leaving all keys released at rest.
Play the full keyboard
Press each key again and compare the force required across the keyboard. Make small screw adjustments until the action is reasonably even.
Check: All 17 keys sound when pressed and stop when released.
