g. Rotate the rotary switch and its knob to an
angle that you like. Then remove knob, tighten
switch to enclosure top, and reapply knob

Tuning
For the OKAY 1, the notes are arranged C to C, from left to
right: C, C#, D, D#, E, F, F#, G, G#, A, A#, B, C. The OKAY 2 has
two octaves: C, C#, D, D#, E, F, F#, G, G#, A, A#, B, C, C#, D,
D#, E, F, F#, G, G#, A, A#, B, C
1. Turn on your chromatic tuner and place it by the
speaker. Find a volume and octave setting that the
tuner can hear and responds to.
2. Starting with the
rightmost
potentiometer, hold its
button and adjust its pot until the note registers as a
high C. The pot will have a two or three octave range,
so just choose the highest C you can accurately get to.
If you reach the end of the pot’s range, it will make a
small clicking sound but won’t be damaged.
3. Once that C is set, move to the next note on its left.
This will be B.
4. Repeat until you’re at the end on the far left
You’re done!! Take a selfie with your brand new and very
incredible OKAY synthesizer. Feel good!
Care
●
The trim potentiometers will hold their positions and
the 555 chip is similarly resilient, but the OKAY is an
analog instrument and may still lose tune over time.
When that happens, re-tune normally.
●
Like arcade console buttons, the pushbuttons are
mechanical and will eventually wear out over time and
