Hi everyone,

I have a Motif XS7 that has been my reliable workhorse for many years. Tonight I sat down to play and I have noticed a bank of keys not working… From the lowest G on the keyboard up to the C. All keys in between do not work either, but those above and below do. the fact it’s a group of keys scares me that it might be something electronic. Any advice on how to proceed would be most appreciated.

update, After reading some other posts I have blasted the keys with some compressed air, which didn’t do anything, then randomly a few minutes later they started to work again. I can’t gig with this board if i lose these notes again. Anyone have any recommendations on what i should proactively check?

Many thanks.

Keys G0 through C1 share key matrix line BK01. A bad connection anywhere between where that line originates and where it connects to the key decoding circuit could cause those keys to be inoperative. BK01 begins on the MK76L board, passes through the MKC and MKH-D boards, and arrives at the EMKS-FD board. A flat cable connection problem between any of those boards could result in the problem you described. So could an intermittent failure in the key decoding circuit, although that’s less likely.

The Motif XS Service Manual can be downloaded from Elektrotanya. Unless you have good electronic skills and experience, I suggest that you do not attempt to repair the XS7 yourself, but find a qualified technician.
