eowave portail: midi to cv interface price : $229.00

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 synthesiser, it provides a direct and versatile bridge for controlilng 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.

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.

features:
8x 16bit cv and 8 x 12bit cv
8 preset configurable via the app (or by sending sysex)
usb c and midi trs input
assigneable midi parameters to control with cc
a lot of output modes ( notes , cc , random , arpeggiator, lfo , envelope...)
