I have the Greg Macmillan board, works the last firmware of midibox 64 with it?, or it only works with the MBHP.
Hi Amando,
i think there is no problem with the v1.00 MB64 Firmware and your Greg Macmillan board.
have a look @ http://www.ucapps.de/midibox/midibox64_v100.zip
…The archive contains two firmwares for MIDIbox64:
 o midibox64_v100_mbhp.hex
  Firmware for the MIDIbox Hardware Platform
 o midibox64_v100_comp.hex
  Firmware compatible with the old hardware design
The only difference between these two variantes is the addressing of the pots. It has been changed for the MBHP to simplify the wiring… (TK)
In this matter the Greg Macmillan board is the old hardware design - and the MBHP is the new hardware design.
