IO Board Mods

Because of the relative simplicity of this section, there isn’t much in the way of mods to be done here.

Change Midi Out to Another Midi Thru

VerifyMe: Someone competent with electronics needs to look over this to make sure it is correct.

Cut the trace to pin 5, and wire it up a 220 Ohm resistor to the Collector of Q50

Alternatively, this could be done in the FirmWare

Double Duty for the Jacks

The ring of Mix In and Mix Out are disconnected, and can be used as inputs (or outputs) for some of the VcoMods, VcfMods, EnvelopeMods or VcaMods.

The headphone out is split at the IO Board with the two resistors R164 and R186. You could disconnect one of them to also make it double as an input or an output.
