Hi at all,
 
	I'm newbie for this forum. I'm guitarist and stompboxes DIYers from long time.
 
	My last project (builded, see images) was a programmable MIDI looper 16channels, for switch (via relays) analog audio signal (send/return from stompboxes) from guitar to amplifier. The goal was to change the mix of the guitar effects sequence.
 
	Now I want to build a box (similar at the BOME box product, but with more simple functions) that:
 
	- has a MIDI input program change (1-128), via MIDI pedalboard (or other device);
 
	- stores internally a routing path, via "translation matrix";
 
	- has a MIDI output changed (in according with a translation matrix).
 
	For exeple: if I send the MIDI PC n.4 into the box, from output the box put  the MIDI PC n.30.
 
	The matrix is simple (for sample):
 
	IN | OUT
 
	1 | 25
 
	2 | 25
 
	3 | 25
 
	4 | 30
 
	... | ...
 
	This type of project was discussed in this forum? Is similar at the "MIDi mapper" project?
 
	Thanks for your patience.
