I know a lot of devices which have mounted smooth rotating encoders with button. Even very old devices.
So I can't understand why it is so hard for me to find such encoder.
Maybe you could recommend any model of incremental encoder for DAW mixer controlling?
So I think it should have as many impulses as possible per revolution.
I can imagine it is the best if it rotating smoothly, without jumping.
But due to fact I want one knob to be responsible for many sliders in my DAW it should be with automation built in (I mean motorized slider) but it's too expensive.
Just had a thought. Why do you want a push switch on the encoder that controls the parameter value? Think about how you want it it operate, you want the parameter to track the rotation. You don't even need one on the encoder that selects what channel the controller is going to alter.
d) get initial (current) value of fader and set the same value on my encoder;
Could you give me link to any explanation of using those external MSP functions in Ableton?
