I have been using midi interfaces for guitar rigs for years. They are often complex, massive, and limited in functionality. For example the FBV only lets you change led colors when used with factory devices but the user can’t decide color. My previous Meloaudio Midi device could only send cc#69 with a value of 0-3 after a complex firmware upgrade leaving 4-7 orphaned on my device with no option to deep dive program to fix. It was semi-flexible. Others have no usb or midi din5 connection or won’t power with pedalboard standard 9volt input or even battery. This device with latest 3.0 Geek mode allows any cc with any value on button press and depress independently. It will even allow a chain of 6 commands to each press/depress if you like for more complex activity! This device can act as a 16x8 x12 command sending any combination of continuous control, program change, and or midi notes!!!! It literally replaces my big guitar midi pedal, page turner pedal, midi foot note keyboard, and control pad for SampleTank at the simultaneously in a footprint less than 1/2 of my previous guitar foot pedals. Pictures are custom colors (beyond basic rgb as you can see) on this device programmed by me with the great new onscreen interface. Getting the new firmware on the device was as easy as using a usb flash drive!!! Quality is superb all around. Only complaint is the spring on the battery compartment makes it a little awkward when removing/installing batteries but certainly not a deal breaker! I’m definitely going to upgrade to wireless module for 40$ asap!
