Strange! Did you try to upgrade it again? Or switch it off/on ?
You can also load the 8 factory presets by default if you press "VCA" + "SEQ" when you switch Der OTO on.
Yes, I did reload it once before I posted (by going back to Biscuit v1.2 first). I updated a third time and now the parameters are editable, but when I push the corresponding button there is no white LED (all buttons stay "off" when pushed). According to the manual, it looks as though these should turn white...
The 8 rectangular switches
The different synth parameters are selected by these switches.
When the “SEQ” switch is off, you can select the parameters you want to modify in Der OTO.
Press once to select the parameters written in white (the switch lights up white).
Press twice to select the parameters written in red (the switch lights up red).
When the “SEQ” switch lights up blue, you can select the step you want to modify in your sequence.
Press once to select the steps 1 to 8 written in white (the switch lights up white).
Press twice to select the steps 9 to 16 written in red (the switch lights up red).
In both above instructions, the switches never turn white. Their "red" state is a flashing red LED.
And I also notice that the SEQ switch alternates colors from a blue to a blue-green randomly when turned on (i.e: it's not always the same blue).
Just FYI - these switches and LED colors do stay constant and of normal color when the Biscuit firmware is loaded.
Additionally, turning the unit on will sometimes result in a mode where there seems to be no functionality (described in first post). The green Filter/Run switch is on, but no other buttons are responsive - sometimes I
can press the SEQ switch and it will turn blue, but there seems to be about 10 seconds of delay between when I press the switch and when the LED becomes active.
If it would help, I can make a video and upload it to show the behavior - though it's probably premature until I update to the correct firmware.
