Title: Translate CC into relative values
Post by MidiKinga on Apr 24^th, 2015, 2:27am

Hi!

I saw a similar question on another forum, but I guess here are all the experts so let me try here.

So, basically, I need to translate following input:

Code:

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
001B4E8C 15 -- B0 63 78 1 --- CC: NRPN MSB
001B4E8C 15 -- B0 62 19 1 --- CC: NRPN LSB
001B4E8C 15 -- B0 06 3F 1 --- CC: Data Entry MSB

into midi CC relative value: -1

In other words, the CC input above shall decrease output CC value by 1.

Then, I need to translate following input:

Code:

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
001D238C 15 -- B0 63 78 1 --- CC: NRPN MSB
001D238C 15 -- B0 62 19 1 --- CC: NRPN LSB
001D238C 15 -- B0 06 41 1 --- CC: Data Entry MSB

into midi CC relative value: +1

In other words, the CC input above shall increase output CC value by 1.

I hope someone can help me with this one. ;D

Thanks.

Strange this is the second question like this in such a short time.

To output an incremented value (CC value +1 or -1) you need to have the current value stored somewhere .

MidiOx's data mapping doesn't have provision to store values. It really just changes one known message into another known message.
But you can program the scripting interface to do this.
Have a look in the Scripting Interface section of the manual.

An alternative to this is Bome's Midi Translator.
As I recall you can do this with the free classic version.

Otherwise there is the Translator Pro

All the best
