Vinicius m'a envoyé les modes d'emploi (en cours d'amélioration) concernant le "Lizard" et le "Multi-LFO".
Je copie/colle (le PDF d'origine contient quelques photos des formes d'ondes. Je l'upload d'ici quelques temps) : LIZARD

You could say that the Lizard is composed of several modules integrated into one. It has a high performance hybrid VCO with multiple operational modes plus 8 VCLFO's (Voltage Controlled Oscillators Low Frequence) totally analog.
The Lizard has 8 VCLFO's totally independent. Each LFO has an output signal and a control input CV of frequency. It has a pot of frequency control and a control group of symmetry of the wave, allowing a range from-tooth saw (saw) to a decreasing or increasing negative or positive through the Triangle. See the photos below:
The frequency of VCLFO ranges from 0.01 Hz (100 seconds) to 10Hz (0.1 seconds), when controlled only by the frequency potentiometer.
The sweep oscillator VCO is a hybrid of high performance and stability, ie, analog / digital. He commands an analog selector that "chooses" what to be “displayed” in the output signal OUTPUT.
He has several modes / operating configurations. The first setting determines the number of steps (selections) it has. It may be 4 or 8.
The second configuration determines which font to be selected: If LEVEL or LFO.
LEVEL Mode can "draw" the waveform of the VCO through the pots LEVEL, above each LFO. This way you have 4 or 8 segments according to the configuration of STEPS. Depending on the shape drawn, harmonic distribution varies dramatically, allowing for literally infinite number of tones. The waveforms below were created with 8 STEPS.
In LFO mode, each LFO becomes "sampled" in real time on their respective STEP, creating a "wave morphing" extremely rich, whose cycle is the result of sound frequencies and symmetries setting the LFO's, lasting hours to return the same way! In this configuration, the pots LEVEL control the grade of participation of each LFO in the "wave morphing". If set to 8 steps, all LFO's will be "sampled", and 4 steps, only the LFO's 1 to 4 will be sampled by releasing the LFO's 5 to 8 for other applications within the modular! What does not negate the possibility to also use the individual outputs from LFO's 1 to 4 for other applications.
The key SEQ/VCO changes the frequency range of the principal VCO, allowing use as VCO (from 5Hz to 10kHz) or as an analog sequencer 4 / 8 steps (from 20 seconds to 120Hz). If set LEVEL Mode, the CV's of each step will be scheduled by LEVEL pots, using as an example look up the waveforms. If set to LFO, the LFO signal at the output will be present at each step. See photo below:
In the WAVE Mode, the first 4 steps will sample signals present in Wave 1 to 4 entries ... If the Lizard is in mode VCO, and if in each input is entering a external Wave VCO (eg Aether Oscillators) the sound becomes infinite.
If the SEQ mode, you can "switch", for example, four external sequencers.
The controls (pots) of this VCO are:
- FREQ - Frequency Adjustment
- Fine - Fine frequency
- FM - Depth of operation of the input FM (Frequency Modulation)
- FM - Frequency Modulation (1V/Oitava)
- CV - Control 1V/Octave default frequency (0 ~ 10Volts)
- HSYNC - Hardsync
- Wave1 to 4 - Signal inputs
- OUTPUT - Output of the analog signal selector
- SQUARE - square Output frequency of the VCO
Module Consumption: 120mA @ +12 Volts /-60mA @ 12Volts
Dimensions: EURORACK 57 HP (128.5 mm x 289mm)

The MultiLFO is a module composed of three VCLFO's (Voltage Controlled Oscillators Low Frequence).
The LFO2 and LFO3 are equal, fully analog LFO's, each with a CV input for frequency control and local control (potentiometer). The input has a CV Width pot to control the depth of CV action. With this, we can modulate each other (and a multitude of other things ...). This two LFO's each one also have, a pot controlling the symmetry of the waveform, ie, the output waveform varies from saw negative to positive, passing through the triangle. In addition, these two oscillators have an square output, influenced also by control of symmetry, ranging from an extremely narrow positive pulse to a negative pulse. Very handy to use as a sync signal ...
The LFO1 is a hybrid (digital / analog) LFO extremely powerful with 8 selectable waveforms: six controls (potentiometers), CV input, input HardSync (with special characteristics), the main output and an output LFO1 NOISE (with a peculiar frequence distribution ...).
The controls are:
FREQ – Frequency of the LFO
WAVEFORM – Select one of eight waveforms, namely Positive Saw, Negative Saw, Square, Triangle, Sine, Exponential, Spike and Noise (with a different distribution frequency from the independent output NOISE).
PHASE – The phase control distorts each of the waves above (minus the noise), the "speed" with which each carry 50% of the wave! Thus, for example, if the wave selected is Triangle, you can do the same as LFO's 2 and 3!
See the drawings below to understand this phase distortion (in the first line was selected waveform Sine, Negative Saw in the second and third triangular):
S&H RATE – Besides all this, LFO1 has its own Sample & Hold. This pot controls the frequency of S & H. When he is at zero (all left), the S & H is disabled. When used in the waveform Noise generates a random sequence. In other waveforms, generates "stepped forms". See photos:
CV WIDTH - Control the depth action of CV.
SYNC MODE – This control is subtle use. It determines if the input HSYNC (hard sync) is ignored, it acts only on the LFO or the S & H or on both! If you want to synchronize the S & H with an external clock, simply place the frequency of the S & H (RATE) much slower than the external clock and voila! Sync to external S & H!
