|NOTES FROM THE UNDERGROUND|
Analog percussion module
The synthesis board is an analog circuit with two VCOs, two envelopes, AM, FM, high-pass filters, and a two-channel mixer.
Triangle core VCOs with V/oct inputs and Fine and Coarse controls.
VCO 1 waves: Sine, Triangle, Sawtooth, and Square.
VCO 2 waves: Sine, Triangle, Sawtooth, Square, Double Sine, and White Noise.
VCO2 has two separate wave outputs, one for the AM and the other for the FM and the Mixer-Channel 2.
Two AHR (Attack, Hold, Release) envelopes.
The hold time can be set internally or externally (Gate ON) for each envelope.
Envelopes can be faded from logarithmic to linear responses.
Each envelope can control the Pitch/Tone of the VCOs (Pitch Envelope), the amount of AM or FM (Envelope 1), the VCA for both channels (Envelope 2).
The amplitude modulation goes from VCO2 to VCO1.
It can be set in two ways: straight to VCO1 or through a VCA controlled by Envelope 1.
The frequency modulation goes from VCO2 to VCO1 and from VCO1 to VCO2 (XFM).
FM can be set in two ways: straight to VCO1, or through a VCA controlled by Envelope 1.
Two-channel mixer for the two VCOs.
There are two HPFs. HPF1 filters the mixer output. HPF2 filters the white noise.
Each project contains twelve banks; each bank contains twelve slots; each slot contains a sound.
All projects are stored on an SD card.
Randomize values on a per trigger basis
Independent random control for each synth parameter
Set ranges to any random value for controlled randomness
Relatively attenuate all parameter-random amounts with a single global random fader
Populate slots or banks with randomly generated sounds
Take a snapshot of the whole project, modify it and go back to the original state.
Parameter interpolation between two slots on a per trigger basis.
Control the balance between the two slots with one fader — crossfade style!
Any of the six CV-connectors can be configurable as both inputs or outputs and set to different ranges (0/10V, 0/8V, -5/5V, 0/5V).
CV-inputs can be internally attenuated
Control almost any synth parameter, value, or setting on a per trigger basis. For example, Accent, Slot Selection, Morph assignments, Next/Prev Slot, Random Slot, Oscillator-Wave Selection, any of the synth parameters (Pitch, Release, AM, FM, Global Random…) or any of the random parameters (Random Pitch, Random Filter, Random Hold…)
Output any parameter-CV values through any of the assignable I/Os
Alt-fader-CV output for controlling external parameters, like Send-FX for each slot.
CV-slot/Gate out — Useful for externally recording finger drumming!
Add dynamics by assigning the accent input to control any one of the synth parameters
Copy Slots (also between banks)
Take a snapshot of the last sound heard (flatten the values for further editing), including the effects of CV-in, Morph, and Random. Very useful for easily creating banks from scratch!
Action over faders has an effect on the twelve Slots. Use hints: Live tweaking, homogenize, “tame” a Sound Bank, or modify all Slot parameters while sequencing the Slots via CV-input.
Save, Load, Name, and Rename projects, banks, sounds and sort them into folders.
