Robota
The Robota is a four-part drum computer with virtual analog and sample-based sound production.
Virtual analog sound production means that the sounds are synthesized in real-time, i.e. produced with a
synthesizer to recreate the typical analog sounds of classical drum computers, such as the Roland Tr-808
and Tr-909, or more recent devices such as the Korg Electribe or the Jomox x-cousin. Sample sound
production uses drum sound recordings (or even other recordings) as the basis for sound production.
After selecting the elementary sound production technique, the sounds of each of the 4 parts (or
instruments) can be edited using modulators.
The step sequencer programmed with incident lighting helps Robota to play. 4 beats in sixteenths (or 2
beats in thirty-seconds) are processed as a loop. At each beat position, the playing positions can be set
by clicking a button. In "Event" mode, the instruments are distributed within the beat pattern. In
"Snapshot" mode you can adjust additional instrument sound settings.
Sound synthesis
The four instruments of the Robota are built identically. Each instrument can create all kinds of drum
sounds – from hissing hi-hats to phat bass drums.
During elementary sound production, you can choose between an oscillator with selectable wave shapes
(sine, triangle or saw tooth) or a sample. In addition, you can add a noise generator can be added. The
oscillator has a pitch envelope (pitch env.) and a volume envelope (attack/decay). It can also be
frequency and ring-modulated. The depth of the modulation can be controlled via an envelope parameter
(Fm/rng dcy). There's also a "Lo-fi" section consisting of distortion (Rectify), bit rate reduction (Crush)
and sampling rate reduction (down sample).
Temporal control via an envelope (lofi dcy) will get the best out of the lo-fi effects. A multi-mode filter
(low-pass/band-pass filter/high-pass) with 12/24 dB steep-side. A comb filter can be inserted. The filter
frequency can be likewise modulated via an envelope. For extra pressure, an adjustable compressor
(compressor, comp resp) is included, as well as tube amplifier simulation (tube).
Parameter (1)
To simplify matters, not all parameters
can be changed on a sound - only those
that are meaningful for the selected drum
sound may be changed (snare, kick, high
etc.). There are four selected variable
parameters coordinated exactly with the
selected preset sound.
Oscillator waveform (2):
The fundamental waveform of the
Oscillators is selected here. You can
choose from
sinus/triangle/sawtooth/sample. If you
have selected "Smpl" you can use the
rotary knob to select a sample, i.e. a
previously recorded drum sound. These
samples are saved in the folder
/synth/robota/samples/. If select custom
samples, they will appear in the selection
list.
