15.0

Controls the pitch envelope level.
Tune
Tunes the instrument.
Oscillator shape (osc shape)
The shaper adds additional frequency shares to the basic sound of the oscillator by artificially reshaping
the wave shape. A sine wave (shape = 0) can be reshaped up to a square curve (shape = max).
Oscillator waveform
The fundamental waveform of the oscillators is selected here. You can choose from
sine/triangle/sawtooth/sample. If "Sample" is selected, you can use the controller to select a sample, i.e. a
previously recorded drum sound. These samples are saved in the folder /Synth/robota/samples/. If you
select custom samples, they will appear in the selection list. If you are playing your own samples, they will
appear in the selection list.
Noise
Adjust the ratio between the oscillator sound and the noise generator.
Attack
Adjusts the attack time. The greater the set value, the softer the attack of the sound. The attack rate is
also applied to the lo-fi and filter envelope curves.
Decay
Adjusts the decay curve. The greater the value, the slower the instrument will decay.
FM/Ring modulation frequency (Fm/rng frq)
The fundamental frequency of the frequency or ring modulation.
FM level (fm lvl)
At a low frequency FM first adds vibration to the sound, at high frequencies and low levels it creates
bell-like sounds, as the level increases metal sounds, and finally noise.
Ring modulation level (rng lvl)
Ring modulation creates typical auxiliary frequencies.
FM/Ring modulation decay (Fm/rng dcy)
Time constant of FM/ring modulation by-product. Only the beginning of the drum sound is affected by
the modulation.
Rectify
Distorts the audio signal.
Crush
Bit rate reduction. Digital artifacts become audible with higher settings.
Down sample (dwnsmple)
Sample rate reduction. Ideal for creating the "old school sound" of older digital drum machines. As it is
increased, the result becomes darker.
Lo-fi decay (lofi dcy)
Time constant of the by-product of the three lo-fi effects which makes the sound "dirty". Only the
beginning of the drum sound of the lo-fi effects is affected if the decay is low. For instance, this makes the
kick of a kick drum sound more interesting.
Filter modes (flt mode)
Filter mode: High cut – sound portions above the cut-off frequency are filtered out. Band pass (BP) –
Sound portions above and below the cut-off frequency are filtered out. Low cut - All sound portions
below the cut-off frequency are filtered out. This mode is set as a preset and can not be changed.
Filter frequency (flt freq)
The cut-off frequency of the filter.
Filter resonance (flt reso)
Filter resonance which increases the sound portions at the cut-off frequency of the filter. If the resonance
is high, the filter itself can also be used as an oscillator.
Filter modulation -/+ (flt mod -+)
Regulates how much and in which direction the filter envelope curve moves the filter frequency in which
