Board (DIY) updated today,
my goal was to keep it as small as possible.
The modified Dunlop mini is serving as a midi controller (2 Midi switches, the 2 on the black board at the right, for Preset + and Preset -), expression pedal via midi external 1, Midi In via original TRS, Midi OUT/THRU via original OUT TRS, and AUX is a TRS for the 2 external switches.
Midi brain is a Midi CPU I still had in stock, but could be done with an Arduino as Midi CPU is not available anymore.
The 4 switches on left on the board are standing switches with layout link, so when pressed the FM3 mini LCD change to the corresponding layout of the scenes, so I see where I am in.
M Vave has 4 switches with tap and hold functions, currently used for looper control, direct tap tempo and tuner access but can do anything else as desired (FM3 has midi learn, so no need to change CC number in the midi CPU).
M VAVE Is Battery powered and is also sending CC of my choice by bluetooth to Logic (seat recording, play stop..)
I used the space in the dunlop to add a 12V to 9V converter so I power everything from the FAS link (up to 500mA)
The Dunlop has 12V plug In, and 9V out to power the SONY wireless.
Zenrigs for protection, and it has exactly the space for the M Vave (just attached with soft magnets, but few ones to keep it strongly sticked)
I can still operate the A-E Knobs on the FM3 if I need to.
More than I need but was fun project and love it.
