Der OTO is the new Biscuit firmware (revision 2) and turns your Biscuit into a monophonic synth.
You can play Der OTO with a standard MIDI keyboard, a computer with a MIDI interface or the internal sequencer.
Der OTO has 2 main modes: Synth and Sequencer.
You can access to the Synth parameters when the central round switch (SEQ) is off.
When SEQ switch is on (lit up blue), you have access to the Sequencer parameters.
The Synth has 2 oscillators: OSC A & OSC B with several waveforms.
OUT L corresponds to the OSC A output and OUT R corresponds to the OSC B output.
However you can use an adaptor (2 mono jacks to 1 stereo jacks) if you want to.
The L & R inputs are inactive.
Thereʼs 1 LFO and 1 envelope generator (EG) to modulate the pitch and VCF.
The Sequencer can play up to 16 steps.
Several parameters (OCT, NOTE, LENGTH, GLIDE, ACCENT) can be memorized in each step.
Der OTO accepts the following MIDI messages:
- Note On & Note Off
- Continuous Controller (for all knobs and parameters)
- Pitch Bend
- Beat Clock, Start and Stop (for synchronisation of the sequencer)
- Program Change
How to select between “DER OTO” and “BISCUIT”
With this firmware revision, you can use your Biscuit as a standard one (Revision 1.2) or as Der OTO.
If you press the “SEQ” (or “BRAIN”), “4” & “5” switches simultaneously while you switch Biscuit on, Biscuit becomes Der OTO and the other way around. This selection is kept into memory.
The color of the startup animation indicates if you are in Biscuit mode (the animation is in red) or in Der OTO mode (the animation is in white). When youʼre in Der OTO , your Biscuit is no longer active.
