Morse is a gate sequencer that uses the Morse code encoding of a word to generate the high/low pattern.
The user uses the buttons and knobs to enter a word of up to 16 letters. The output is the encoded word.

Normal gate outputs go low on the falling edge of the clock signal
on DIN. Latched gate outputs stay high across multiple pulses if
adjacent signals would be high.
Because Morse outputs a binary on/off sequence instead of
long/short gates, it doesn't naturally sound like morse code.
But with some clever patching you can create audible morse code!
Patch the output from CV1 into an envelope with a short
decay and the output from CV4 into an envelope with a long
decay. Connect these two envelopes into your VCA (or if your
VCA only has 1 CV input, use a mixer).
If your envelope generator has CV over the decay, you can patch
CV1 into the envelope's trigger, and CV5 into the decay CV.
You may need to attenuate the CV control to get the durations right,
but this will let you generate long and short pulses with a
single envelope.
