hi guys,

Ijust bought an old 707 to try and mod it myself....... now i have
some problems with it, that probebly why ot was so cheap, the high and
low tom don't work, there is no sound at al from these 2 the mid tom
does work, there is no sound at all anyone any sugestionson this.

Then there is this, the memory from my 707 does not work properly.
When it is turned of the internal memory gets scrambeld and when i
turn it on the notes are everywhere in every pattern, the strange
thing is when i leave it off for a short time after i reset it the
preset patches are still there, anyone any idears on this one
.......
