APC40 + Bome MT, Almost there!

[Semuta]

In Bome's, you define "default" connections in the midi patchbay, but in your rules, you can specify ports to listen on, and ports to output on. You can tell a bome's rule to listen on a particular midi port and output on another specific midi port that may not be connected in the patchbay. You could have a bome's rule that listens for a particular command, and will send a command right back to the APC to light a button or whatever.

Can you explain how the hex <-> dec conversion works a little?

[andyappleseed]

Rather in the context of Bome's MT "rules" and "variables".?

[Semuta]

Well, the conversion works more or less as follows. Midi messages are based on binary values for the most part. This means that you see numbers in ranges that reflect multiples of 2. 2 4 8 16 32 64 128

128 is a number you see often, though more often counting from 0 as in 0-127. Hex is another counting system, and it's a little complicated. Basically it uses numbers and letters to represent numbers.

0=0
1=1
2=2
3=3
4=4
5=5
6=6
7=7
8=8
9=9
10=A
11=B
12=C
13=D
14=E
15=F

As you see there are 16 "numbers" in hex, so it's a base 16 counting system. By contrast, binary is a base 2 counting system, and the only numbers you use are 0 and 1.

A wiki article on the hex counting system can be found at http://en.wikipedia.org/wiki/Hexadecimal

Midi is a weird mishmash of all of things, but generally, I think of midi in decimal terms, so a hex converter is usually necessary for me to do this stuff: http://www.easycalculation.com/decimal-converter.php

Just understand that Hex is a different counting system, but ultimately, it's representing regular values.
