For manual control there are: - 7 rotary encoders - 2 switches with 3 positions - a trigger button For CV control there are: - one input per manual control (incl. trigger of course) - one output The encoder parameters are not what the label suggests in their functionality. But they’re extremely musical and a lot of fun. I would describe the knob lay out as a 4-column layout. For example, the most left column features 3 parameters + 3 CV inputs. Knobs, switches and inputs are not exactly aligned with each other like on a grid Let me tell you about the specific parameters in each column (from top to bottom). The descriptions are from the non-accessible manual: First column: 1 The pitch knob and CV input adjusts the pitch of the fundamental oscillator. This is a 1v/8va standard input. The knob sums with the CV input. 2 The spread knob and CV control the frequency spacing of the oscillators. This allows the overtone series to vary from a purely harmonic to very inharmonic. 3 The harmonic knob and CV control the harmonic decay of the oscillators. When fully le, only one oscillator is audible. This simulates many simple analog bass drums. As the parameter is increased more harmonics blend in lasting longer periods of time. The knob offsets the CV input. Fully le the tone produced is a single harmonic tone. From there to the rst quarter a second tone fades in. The remaining turning extends rst the decays then the amplitudes of the other four harmonics. 4 Pitch CV input 5 Spread CV input 6 Harmonic CV input Second column: 1 The morph knob and CV control the waveform of all oscillators. This blends through sine, triangle, saw, and square continuously. The knob offsets the CV input 2 The fold knob and CV control the innifold section. For the rst 3/4 of the range this sets the threshold of the folder. This folder will dynamically add multiple fold stages to maximize the amount of folding based on the fold threshold and signal amplitude. When the control is in the top quarter of its range, a pulse train based on the signal is mixed in to give even more harmonic content. The knob offsets the CV input. 3 trigger button with LED 4 Morph CV input 5 Fold CV input Third column are only cv inputs for Attack & Decay at the bottom of the module: 1 Attack CV input 2 Decay CV input Fourth column: 1 The attack knob and CV input adjust the attack for all oscillators. When le of center, noise is added. When dead center, a classic analog-style pop is produced. When right of center, the knob slows the attack. The knob offsets the CV input. 2 The decay knob and CV input adjust the decay for all oscillators. The knob offsets the CV input. 3 The spread knob and CV control the frequency spacing of the oscillators. This allows the overtone series to vary from a purely harmonic to very inharmonic. 4 Skin/Liquid/Metal switch + LED: The mode switch selects between the three modes. Skin is a six-operator additive synth for tonal sounds. Liquid is a six-operator additive synth with a pitch envelope to add extra kick. Metal is a six operator FM synth for producing noisy and alien sounds. This setting can be controlled by CV into the S/L/M jack. 5 Basso/Alto/Treble switch + LED: The range switch offsets the pitch by two octaves in Alto mode and four octaves in Treble mode relative to Bass mode. This setting can be controlled by CV in the B/A/T jack. 6 Skin/Liquid/Metal switch CV input 7 Basso/Alto/Treble switch CV input 8 Out: The output is a low-impedance audio source. The output varies signicantly based on the parameterization as compensation for loudness occurs
