Hey gang
Selling my old Impulse49 MIDI controller as I just upgreaded, and it’s got some jumpy/glitchy knobs n such. Is this just a job for a gentle touch of compressed air, some light brushing and contact cleaner?
Thanks in advance

how long have you been using it for? could simply need some basic cleaning or be the encoders worn out over time and might need to be replaced
a long time. 7 years or so i guess. can’t remember exactly. Gonna try some compressed air and then step up to contact cleaner if necessary.
