i have a composer with the same problem - but i've
cured it (sort-of)... try holding down one of the
organ presets buttons(1-4 on mine)with your finger
(quite heavily).
does it work, does it stop working when you take your
finger off, and sound quiet again.
if that's the case, you can wedge the button under the
top lip of it's respective hole by pushing it down and
slightly away from you, and it should stay in place
-this only works with one button at a time... this
should make it work again.
this is only a stopgap measure though - best get the
lid up and have a look -although i've been using my
studio-bound composer like this for a few years
without any ill-effects.
hopefully someone with a soldering iron here, will be
able to help both of us!!!
