MIDI/CV Interface

Portail is a powerful compact and highly configurable digital interface designed to connect your MIDI instruments with your eurorack rig in a versatile way.

Multiple Connections: Connect seamlessly via TRS MIDI or USB-C.

Configurable Outputs: Offers up to 16 assignable CV/Gate outputs (8 x 16 bit outputs labeled CV and 8 x 12 bit outputs labeled GATE) . You can configure them as classic V/Oct and Gate pairs, polyphonic voice outputs with various modes, dedicated drum triggers , dynamic gates sensitive to note velocity , lfo, envelopes, clock. Control the conversion: Parameters can be controlled directly via incoming MIDI CC messages( you can midi learn the modulation) for example control the ADSR parameters or the range of a random generator with midi CC messages.

Dynamic Response: Create patches with expressive control using dynamic gates that translate MIDI velocity into varying gate levels ( perfect for analog modules).

Deep Customization: Use the web configurator to define the precise behavior and assignment of each of the 16 outputs. You can check the (still in developement) configurator here : https://www.eowave.app/portail/

Integrated Modifiers: Enhance your control signals with midi effect like gate probability and scale quantization, adding variation and musical structure directly at the output stage.

Available modes:

Note out: Convert the midi not to a cv 1 V/oct output. you can set the pitch bend range, the amount of vibrator on the CV and the glide time between notes. You set a polyphonic stack.

Gate out: output a gate when a midi note is played. you can set the range of the gate, create small attack and decay Set the gate amplitude is velocity sensitive and if the gate retrig if a new note is played while a previous one still pressed(legato).

Trig out: Output a trig when a specific midi note is played. you can set the length of the trig, if the amplitude is velocity sensitive. The minimum value and the range.

CC/Pitch bend: Convert a cc to a cv. you can set if there is afilter to smooth you output.

Velocity: Output a cv coresponding to a note velocity

Aftertouch: Output a cv coresponding to an aftertouch signal

Poly Aftertouch: Output a cv coresponding to a specific note aftertouch signal

Clock: convert the midi clock to gate clock. you can set the type ( clock, start/stop, rest) the division,and the length

LFO: Output a cv lfo. you can set the waveform and the clock division

Envelope: Output a cv envelope. you can set the type( AD,AR,ADSR,Loop) and set the attack, decay, sustain, release.

Sequencer: A simple sequencer who output notes.

Arpeggiator: arpegiate your midi notes. you can set the type , time divisions and the latch mode.

Euclidean: an euclidean sequencer who output gates

Random: Output a random value synced to a clock or each time a note is played. you can filter it.

Available effects:

Scale: add a classical tonal scale to a cv output.

Microtonal: Add a microtonal scale to an output( you can have 8 tables of microtonal scales on your portail)

Random: randomise the probability of note change

Delay: delay a midi event note

Probability: modify the probability of a gate to be outputed

Note filter: limits the maximum value that a sort will take into account.

Velocity VCA: use an output to modify the amplitude of another output

Random Octave: randomise the octave of a note output

Math: binary operation on midi notes

Portail provides a direct, flexible, and deeply configurable link between your MIDI gear and your modular system.
