I don't believe it! I left my Crumar Spirit standing on it's side near the
window for a day or two - the afternoon sun beaming down upon it's black
underbelly. But this isn't exactly the tropics, it's south west England.
Not really that hot (even at this time of year).

Yet, on completing tidying the studio up, returning the Spirit to it's
usual slot on the desk, the keyboard scanning doesn't seem to be doing
very much any more.

Sometimes when I power up there's a note there already (that you can't
change using the keyboard) and sometimes there is nothing until I hit a
key - and then you get a note that you can't subsequently change using the
keyboard.

Putting the arpeggiator in "ripple" mode, the Spirit just plays up its
entire range and then starts at the bottom again.

Any ideas where to start?

I have checked the basics like jumper cable connections, made sure no key
is shorting, etc. But, I don't really have much more than a multimeter to
probe around with. Any suggestions for homing in on the fault would be
great, before I resort to professional servicing.


Thanks and regards,
Matt Nolan.
