Like with the rest of the Volca family, to add a midi out connection to the Sample is an easy mod. The PCB has the solder points identified (thx Korg) and they are easy to access, as soon as you open its case you can clearly read MIDI OUT printed in small letters.
It`s not necessary to connect the ground on this one and it will work correctly without it but if you want to you obviously can.
I do believe that the hardest part of this mod is actually to drill the faceplate and to find the perfect space to fit the plug. There`s a metal plate on top of the plastic case and you have to drill both of them…obviously..
Since i`m on the move i can`t afford to carry tools with me but i believe that with the right one this is a breeze to do and with the wrong one it`s neither impossible, since i just used a swiss army knife to drill a hole on it i am sure about it!
It`s a bummer that it can only send one note on each channels so you can`t send 10 midi note messages in one channel, you can only send C2 note messages in each channel from 1 to 10.
I use it as a simple sequencer for my Yamaha FB-01 and it works well. For instance if you want to sequence a drum rack in ableton you have to create different instruments on different channels, which is not that handy, but if you want to get creative you can always design a software patch to convert the MIDI messages sent by the Volca, or maybe create a max4live patch for this. In case you do let me know!
