Hey DjC, you got a good one
, you probably would have needed to do the battery anyway. So just to prove it's definitely the battery (and it sure sounds like it), Turn it on, program 2 patches, change between them (all should be good and work fine). Power off then on again, oops patches now lost... then definitely battery
. I assume you are chatting with MJMP to remedy this ? Again, unless the battery had been changed recently, you would have had to do this anyway. From what you say re the sound, I'd keep those tubes
, sure play around with some others but not all tubes blow you over like you've described.
The error messages are described in the manual, but it's usual IIRC for the preamp to do a full startup check (including file checksums (C1,2,3 etc)) when the power to the ram has been off/too low. This also seems to happen when you remove the Z80 CPU and re-insert it. And also when you change EPROMS
. This part of the MP-1 is just a computer after all.
BTW how's the boogie poweramp sounding ?? it should kick some but, they are not shabby amps.
