MIDI keyboard fault
Is there a MIDI doctor in the house? I've been given a 90's Studiologic SL-880, an 88 note weighted keyboard with an odd fault. Utilising 'Midi Ox' software the k/b occasionally and momentarily switches MIDI channel by itself. If for instance I'm playing F# on ch 4, F# ch 1 appears in the Ox list?
Is this likely to be the microcontroller (ST9036C1) on the blink or something more insidious?
I should say I have reflowed the solder joints on the board and laboriously cleaned all the keyboard membrane switches
Many thanks
