Mocante

Interrogajoke touch controller

The Mocante module is a crossover from the Tocante series of touch-instruments, geared for Eurorack by
Mobenthey. It features a twenty-four operator array of oscillators- in this case phase analysis units- tuned by
capacitor series in the Tocante scale. As a touch controller, it outputs a control voltage representing the unique
tunings of this scale, a gate signal, as well as a host of witches-tones and square-drones that derive from the
Phase Lock Loop (PLL) machineries within.
Mocante is the first of Mobenthey's ultra-raftable modules series, featuring all circuitry and the front panel on
one circuit board. The final module thickness is only as deep as the 3.5mm jacks and potentiometers- not more
than about a centimeter, so it can fit in a thin wooden case similar to those used for the Tocante instruments
proper.
Mocante is a 56HP Eurorack module that runs on +12 and -12 volts. Actually it completely shuns the negative
twelve volts, and thus it can run from a unipolar, plus twelve supply. This helps make it raftable, as it only
requires a branch power line from the increasingly common 12V trunk. Thus, when ordered with a wooden
case, it has a 2.1mm, tip positive, 12 V jack to power it. Also, it can be powered by 9 volt battery. If ordered
without a case, for Eurorack mounting, it will come with a power connector traditional to that format.

Mocante has three main areas of touch:
• Triangle Touch is the traditional touch controller, associated with the CV and Gate outputs. When
untouched, the CV outputs an undefined voltage, and Gate outputs a logic low (about 0.4 volts). When
touched, the CV outputs a voltage proportional to the frequency of the operator, and Gate goes high
(between 4 and 7 volts).
• Squares Touch takes the ultrasound machinery of each operator and octave shifts it into audible and subaudible
ranges. When touched, they manifest an output at “Square Drones.” That jack is unbuffered so it
can potentially act as input, to insert a signal into the toucher traces.
• Circular Touch is the most ephemeral, associated with the hard and soft witches-tones outputs. It enables
the ultrasound signals at each operator to heterodyne with others, creating audible whistling sounds and
other noises... Soft witches-tones use heterodyne phase comparison to generate sweeter, sine-like
sounds, whereas hard witches-tones use phase-lock pulses to make sawtooth forms.
