Eowave Portail Eurorack MIDI-to-CV Converter Module

Manufacturer's description

Portail is a powerful, compact and highly configurable digital interface designed to connect your MIDI instruments with the Eurorack environment. Created to fit with the flexibility and interconnectivity of modular synthesisers, it provides a direct and versatile bridge for controlling your rig.

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.

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 note 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 a filter to smooth your output.
• Velocity: Output a CV corresponding to a note velocity
• Aftertouch: Output a CV corresponding to an aftertouch signal
• Poly Aftertouch: Output a CV corresponding 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 that outputs notes.
• Arpeggiator: Arpegiate your MIDI notes. You can set the type, time divisions and the latch mode.
• Euclidean: A Euclidean sequencer that outputs 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 outputted.
• 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.

Main features

• 8 preset configurable via the app (or by sending sysex)
• USB-C and MIDI TRS input
• Assignable MIDI parameters to control with CC
• A lot of output modes (notes, CC, random, arpeggiator, LFO, envelope…)
