Hello MidiBox folks,
I have been working on reviving an SL990 keyboard. So far I have Fatar TP40GH -> DF adapter -> DIO_Matrix -> Core_STM32F4 with MidiBox KB.
The issue is that while some keys work and are mapped correctly, there are many keys that do register at all. Non-working keys include F0 through G#3 and everything above A5.
As a test, I loaded NG to the core and found that previously dead keys on KB did register as in the MIDI in section of MIOS Studio. Does anyone have any insight into what the issue could be? Much appreciation for any help. Thanks!
