Morse

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.

Inputs & Outputs

I/O	Notes
`DIN`	Input clock/gate source
`AIN`	Unused
`K1`	Unused
`K2`	Select the letter to edit
`B1`	Cycle the letter one position backwards
`B2`	Cycle the letter one position forwards
`CV1`	Gate output, treating `.` as high
`CV2`	Latched gate output, treating `.` as high
`CV3`	End-of-letter gate
`CV4`	Gate output, treating `.` as low
`CV5`	Latched gate output, treating `.` as low
`CV6`	End-of-word gate

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.

Patching Ideas

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!

Idea 1: Two envelopes

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).

Idea 2: CV-controlled envelope

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.
