I have a hammond organ pedal board with "reed relays". I am fairly new to the midibox technology. What I am trying to do is convert it to a midi pedalboard that I can connect to a synth module. I understand that I can use the midibox as the midi controller. I have no clue where to start however as far as what midibox, peripherals etc. I am versed with building analog circuits etc. but the midi is new. Any help you guys could provide on where to start and how to progress would be appreciated
