Is there anyone who knows a good way to realize an incremental controller?

Basically what I want is a knob and every time I turn it one tick clockwise I get some sort of tick or signal that it has moved one step clockwise and if I move it counter-clockwise I get another signal for that.

For example if I would get one note-on message for clockwise movement and another note-on message for counter clockwise movement.

How does endless MIDI rotary encoders work?

Do they just count up to 127 and then continue to 0 and start counting up again?

In that case I could maybe make it work with something like that.

Basically what I want to do is to start a program (MAX Patch), but I don't know the positions of the physical knobs, so when someone turns a knob I just want the value to change from where it is, not jump to the MIDI value of the knob.

Anyone knows a good example both of a patch for this and also suitable physical controllers?

So the issue you're going to hit is that at a hardware level a rotary encoder and a potentiometer are different. The pot has a limit at the bottom and the top and the rotary doesn't. You can't really make a pot behave like a rotary unless it is sends messages after you get to the limit, but a true pot doesn't. The max coding is not that hard, you can use the 'change' object, or a counter with and inc and dec message, and so on. But I'd check out what you get from your hardware first with a midi monitor to see whether it will be possible.

in fact it doesnt matter much what they do - it is not too complicated to interpret steps up as + 1 and steps down as - 1

as long as the physical controller is endless in a way, you can translate its output to + and - later in max.

One trick you can use to fake it with non-endless ones is to use a button to disengage it, so if you bang it to the top, you turn off the input, move it, return on the input.

I want to build a small custom MIDI interface for a test setup.

Are there any kits that support endless encoders?

I have heard that some controllers can be set to just output the delta rotation as a message instead of an absolute value. Anyone know if there are some customizable controller available that can do this?
