exactly how the midi controller works here depends on the controller, and how it
is set up
I was wondering which is the best way to avoid this problem.
is it possible to upload my data (preset) to my midi controller?
assuming the controller you are talking about is rotary knobs or sliders,
then some of them have sliders with motors which will move the slider to match a
value sent to that channel, but without motors obviously the position of the
slider IS the memory of the last setting and you can't change that without using
your fingers!
BUT with some controllers you can set them to not send data until you have moved
the slider to match the last value you sent to that channel. Clumsy, but much
better than jumping back to the old value as soon as you move the slider.
If you are a little careful the pd gui sliders and hardware motor sliders can be
set to reflect each other and avoid fighting each other in a feedback loop.
With rotary encoders, if they are the type which can rotate endlessly then
usually they just work easily, and if your controller has leds around the knob
to indicate the channel's current value then these are updated when you send to
that channel.
Rotary encoders with a fixed start and end point are like the sliders without
motors, see above, they are fine when they are the only thing controlling a
single channel, or when any new preset sent or channel switching is always to
the fully up or down setting.
If you are talking about buttons, often the controller has options regarding
what the send, if they act as toggles or send set values etc.
