Synthtopia reader monomod sent us word that he’s published a Korg Monotribe mod that lets you add individual outs for the drum sounds:
The main intention on this was to get the most flexibility.
So you can just get the drums mix separated form the synth, if you maybe have only two channels free on a mixing desk or your recording equipment, or you can have all four parts of the monotribe separated from each other and go ahead with an advanced mix.
Korg seems to be very open to Monotribe mods, labeling the PCB clearly to make things easier for DIYers.
See monomod’s site for details.
