MOTM

This MOTM-650 MkII have at least one arppegiator in it, right?

I started thinking this weekend about a nice arp hold feature to have. Fully
featured it would need an On-Off-(On) toggle switch and a jack.

Switch up = Hold Off 
Switch middle = Hold On
Switch down = Hold Reset

Jack accepts standard +5 gate and trigger signals etc

When switch is up, a positive voltage into the jack will hold onto any notes
present. Drop the voltage and they are released.

When switch is center, any notes present will be held onto. A positive
voltage into the jack will release all notes and not hold again until the
voltage drops to zero (or whatever threshold is common) My thinking is that
a trigger would be used in this instance to clear all the held notes and
continue to hold any current ones.

The momentary down position of the switch does the same thing as above,
clears all the held notes and doesn't hold anymore until released.

I'm not sure if it would be a simple matter of sending "fake" MIDI pedal
hold signals into the MIDI stream or to just do some direct programming into
the processor etc.

PS - if you want to get really fancy, the level of the voltage into the jack
could hold notes based on a time period or???:

+5 = held indefinitely/none held
+4 = held for 4 seconds/cleared if older than 4 seconds
+3 = held for 3 seconds/cleared if older than 3 seconds
+2 = held for 2 seconds/cleared if older than 2 seconds
+1 = held for 1 second/cleared if older than 1 seconds
+0 = none held/held indefinitely 
(switch up/switch center)
