FeatureReq - Offset for MIDI notes (aka "shift octave") #59

Closed 1000tongues closed 6 years ago

Hello, and thanks for both this library and the thorough explanations of how to flash on an Uno (works perfectly)!

Feature request: I've tried a 5x5 ButtonMatrix on my Uno, which works fine. Planning to hack together a two-octave keyboard controller. However, I'd like to be able to step the octave up and down - meaning, press a button, subsequently add 12 to all note values. Press another, subsequently subtract 12.

Is this possible?

Arduino UNO MIDI Controller library: ? 3.1.0 ?
Arduino IDE: ? 1.8.5 ?
Operating System: ? Windows ?
Operating System version: ? 10 ?

This feature is implemented in the next big release of my Control Surface library.

That part is more or less finished, but the API has changed completely, and I haven't documented it yet. If you're brave, you can look through the new examples (there aren't many yet) and the source code.

The same can be achieved using banks of width 12 and bankselectors. However, keep in mind that the MIDI_Controller library does not fully support banking of button matrices (IIRC) because you run into trouble when trying to change the bank while a button is pressed.
This issue has been resolved in the Control Surface library.

Good news! Thank you for the reply, and for pointing me to the control surface library which I'd missed.

At this point I think what I want to do is far enough off of your plans that it's unreasonable to expect a ready-to-use library such as yours to solve it. I should roll my own, since i probably want to drive some multiplexers and have each note-on event remember its note number so the correct note-off can be sent.

But I'll be following your projects with interest, it's super inspiring!
