for the first time i wanted to input cv signals into the aleph. i had inconsistent results : sometimes i could read from dac0 and dac4, sometimes only from dac0 or dac4, and never from dac2 and 3. i thought something went wrong with the dsp processor. i tried to reboot and this is what happened, quoting @instantjuggler from this thread
my sd card suddenly became corrupt.
for whatever reason my SD literally fell apart, as in the plastic abandoned ship and started to peel and flake off in layers on the end that gets inserted!!?!? it was the card which shipped with the unit, and i never had problems with it before. no idea why in the world it would have done that, have never seen that before.
now i’m stuck : i’m not able to launch the bootloader when i power up the unit.
(since i couldn’t see the application, i thought the sd card was corrupted, but i’ve tried 5 different cards, 2 different readers, and copying or reformating 100 times at least. each time very carefully, as described here : http://www.monome.org/docs/aleph/updates/).
if i launch the aleph while holding down the mode switch, the screen looks like this :
i can use encoder 2, and get this :
the switches and the other encoder doesn’t work.
if i launch the aleph to load a scene, the screen is black and after using the mode switch, it looks like this :
and i can navigate with encoders 2 and 3 :
there’s also a grey line in the screen (which is not there when the screen is black after powering up the unit) :
i tried to launch the prgm app, but it didn’t work. i get the same screens.
i absolutely don’t know what to do now. (this is OSX 10.10.5).
thank you for your help.
