Skippy is a matrix and non-matrix polyrhythmic sequencer (linear and logarithmic) which offers four completely independent tracks with a very simple interface: one button per track, one function per screen, no sub-menus.

• Possible saving of 64 configurations.

• Internal connection with expander module (coming soon) and with Zazou, generative composition module (coming end of 2023).

Functions per track
– BPM (10 to 400)
– Number of steps (1 to 64)
– Linear or log
– Random function
– Chaotic function
– Direction: clockwise, counterclockwise, ping-pong, pause
– Number of steps before the start of the sequence
– Number of steps before the end of the sequence
– Gate duration

Specific algorithms
– Euclidean (Bjorklund)
– Matrix Patterns
– microtiming patterns
– matrix rotation

– External clock input or Reset
– Clock output
– 1/1, 1/4, etc.

– SYS: save, load, new, clk/rst, clk

Mûmack is built from a temperature-stabilized analog source producing the three classic waveforms: triangle, saw, rectangle. This basic signal can be altered or enriched in several ways, which can be combined with each other, and associated with one VCA per mode.

Peak Compressor
In the central position the signal is not modified. Turning the potentiometer to the right or to the left will compress the signal positively or negatively. It is this signal that will then feed Usual, Mûm and Hack. An LFO is dedicated to the compressor, controllable in speed and amplitude. A CV input with attenuator can also control the compressor.

The three waveforms are freely mixable, a CV input and a potentiometer can change the shape of the rectangle wave (PWM). The compressor intervening upstream, it can strongly influence the final form and the amplitude of USUAL. This produces complex analog waveforms, moving in time with the LFO or the CV input. The linear potentiometer makes it possible to mix the signal with the others, and to dose the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

The Waveform potentiometer move the waveform of Mûm continuously from a attenuated triangle to a more pronounced triangle, then to a sinusoid and finally to a square wave. An LFO allows you to add a vibrato adjustable in speed and amplitude. The linear potentiometer makes it possible to mix the signal with the others, and to dose the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

Mûm's signal is taken up in a Wavefolder + compressor. Depending on the settings of the Peak compressor, and the three LFOs, we obtain complex, moving, organic waveforms. Again the linear potentiometer allows to mix the signal with the others, and to adjust the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

The three channel (Usual, Mûm, Hack) are mixed and brought together in a single output. The output volume is adjustable and a CV input with attenuator works like a VCA.

The voltages produced by Mûmack, as is the case with many analog VCOs, can be high. The mixer allows them to be attenuated if necessary. Each of the three channels, and the product of the three, can be controlled by the VCA, with attenuator. The VCA is designed to add distortion at high values. The mixer is exponential for more subtle adjustments in low values.

Switchy is a module that allows you to turn on or off up to three modules (or busboard) independently of each other.
No need to turn off the whole case: All three voltages (+12V, -12V, 5V) are interrupted at the same time.
Used to reduce the background noise of certain "noisy" digital modules when not in use, to initialize certain modules or change their function, to change an SD card, to relieve the power supply with energy-consuming modules, etc.

Tech Specs

Width: 6HP
Depth: 30 mm

Current Draw per ON switch:
+12 V 20 mA
–12 V 20 mA
+5 V 20 mA

Transpos lets you transpose three CV channel with a single source.


The voltage of each CV input can be varied by plus or minus two octaves depending on the switch and the potentiometer of each channel. Transpos uses precision regulators: for example if we increase by a fifth with the switch on "+" we reduce it by a fifth when we pass on "–".


The 1V/o CV input will influence each of the three channels. By turning the CV potentiometer you can globally increase or decrease the transposition of the three channels at the same time.

It is quite possible to combine adder and transposer.

Tech Specs

Width: 8 HP
Depth: 40 mm

Current Draw:
+12 V 70 mA
–12 V 70 mA
+5 V 0 mA
