No zero value from mod wheel

[bluebell]

Hi all,

I have a Alesis Q49 USB-MIDI master keyboard. I noticed that my mod wheel doesn't go back to zero what keeps some synth sounds slightly vibrating. I didn't find a way to recalibrate it.

Code: Select all

hm@regen:~$ aseqdump -l
 Port    Client name                      Port name
  0:0    System                           Timer
  0:1    System                           Announce
 14:0    Midi Through                     Midi Through Port-0
 20:0    Q49                              Q49 MIDI 1
hm@regen:~$ aseqdump -p 20:0

Are your keyboards better?

I am trying to subtract 2 or 3 and have Midifilter.lv2 ("Scale CC Value") correct it.
