Just finished putting new membrane panels on my original CP that I bought in 1984, WOW, it's back!, (thanks Paul). Honestly, changing those was pretty easy.

1. Have a couple of other issues that I could use some help on. It appears that one channel is out. When doing the channel check, number six doesn't light up. Any suggestions on how to start down that road? I simply turned it off so that I don't get the every sixth key with no sound, but that's not a long-term solution.

2. So far, I've not been successful in getting factory patches loaded. Tried sysex via midiquest and MidiOX and .wav via the MidiOX. The CP just doesn't respond at all. Am thinking of trying to find a cassette player (haven't had one in years) and trying that. Should it be possible to recored the .wav onto a cassette and then load it that way, or...?

That's about it, thanks in advance for any suggestions.
