Incremental mode

[Nat]

I don't know where to post this but i'll post it here anyways.

I'm my ever growing quest to gain the ultimate amount of knowledge, I have the following question.

I'd like to know what message a midi controller sends when it is set to send relative messages (+1, -1).  From a coding stand point, is it easy to implement ?

Thanks,

Nat

Hi Nat,

there are different formats for sending relative values, they are documented under http://www.ucapps.de/midibox64e_tutorial_en.html (search for "encoder mode").

You need a coding example? Then tell me for which type of message (or for which host application)...

Best Regards, Thorsten.

Thanks, the tutorials answered most of my questions, the only thing I wonder is what is the complete string to send, from the tutorial I can assume the ending is

40 41 Increment

40 3F Decrement

00 01 Increment

00 7F Decrement

And what is the advantage of those modes over the one described at the end that is in the midi specs ?

Thanks,

Nat

Hi Nat,

yes, your assumptions are correct. Most software can also handle with the "+/- <speed>" setting which should be more prefered, it "feels" more natural (hard to describe if you never tweaked a MIDIbox64E ;-))

The last mode, which is based on the MIDI spec, doesn't include a speed value, therefore most software manufacturers prefer the other (non-standard) modes.

Best Regards, Thorsten.

Thanks, so the full midi string would be liek a normal cc but instead of usual 1-127 digit I replace it with 41 or 3F ?

example :

176 7 41

40 is a hexadecimal number. So: "176 7 65" for increments. Or better write "0xb0 0x07 0x41", which is the same, but looks better.

You never wrote what you plan to do with this knowledge...? ;-)

Best Regards, Thorsten.
