hey everyone, greetings from detroit.
finally got the new BA6110 in the mail, as i had a bad datecode chip, it turns out.
now, when i power it up in keyboard mode, notes are constantly on, and when i press a key, it silences the note, and triggers that note upon release.
i've tried firmware v1.04 and the newest meow19 -- same results.
any ideas?

this is where it gets weird. i've got the boards out of the case, and jacked into headphones/power on the bench.Altitude wrote:sounds like you have something in backwards. Whats it do in random mode?
when it's in random mode, it'll play an occasional note, but mostly a bunch of clicking. when i touch my finger to a couple of random points next to and under the volume knob, it's almost like it drops a couple of octaves -- it plays random notes like it should, and like it does on the other one my friend built. the volume is also *seriously* attenuated, though when i touch those solder points to make it work right, the volume is as loud as it should be...
i've gone over the board a couple times, and i can't find any glaringly obvious errors like bad joints, or BANNED soldered in backwards. i was mad careful to solder in the transistors according to the silkscreening on the PCB, though i read in another thread somewhere that a couple of the 733p's might have been mislabeled with regard to the BCE/EBC pinouts.
any ideas?

you definitely have something 'backwards'. The symptoms you describe are an envelope that's firing in reverse, as it were.darkcube wrote:when it's in random mode, it'll play an occasional note, but mostly a bunch of clicking. when i touch my finger to a couple of random points next to and under the volume knob, it's almost like it drops a couple of octaves -- it plays random notes like it should, and like it does on the other one my friend built. the volume is also *seriously* attenuated, though when i touch those solder points to make it work right, the volume is as loud as it should be...
