hello Ingo,

Selon ingo haenlein superscalar@gmx.de:

I wrote a patch which parses incoming mididata from an external midi controller and routes them via contoller numbers to a ladspa plugin. Everything works. Controller A controlls cutoff B resonance. My problem is, that if i tweak controller A e.g. to a value = 0 and
then contoller B, which has e.g. a (former) value = 100, the value of B
jumps to the value of A for a short time. After this delay B has the
right (old) value.

it's not normal

you could check this (wild guesses):

• the MIDI control change numbers must be different
• mapping from physical control A to cutoff and from physical control B can be

done entirely in parallel (it's easier to program and you don't have to route :)

this setup works for me (copy paste in a txt editor if you have an html-only mail client):

outside world

 physical_A (set to midi cc number X) // in you MIDI controller/sliderbox
 |
 (MIDI cable transmission)

inside the computer (pd)

 [ctlin X] //routing is done here by writing "X"
  | 
  |                                [r interpolation_time_for_conversion]
  |                                |
  |                                |
 [pd value_scaling&convert_to_signal]
  |
[vcf~] // or another filter; here, center inlet~ = cutoff

(same for physical_B, with Y instead of X (X != Y) and using the right inlet of [vcf~] for controlling Q)

you should attach your patch maybe
