" I've received some more info from Laurent over email, I hope he doesn't mind sharing this with you:
The River = The RiverKey + The River + The Triko. The built-in keyboard is a Fatar TP 8S, one of the best keyboards to date.
The Riverkey handles information from the internal keyboard and midi / USB drivers. A profile is a combination of 4 layers. Each layer defines:
- A range of keys* (start note and end note)
- A source (internal keyboard, midi, USB)
- A destination (The River, Midi Out or USB Out, CV + Gates)
- A mode (polyphonic, paraphonic, monophonic)
- A transposition (octave / semitone)
- An automaton (arpeggio or sequencer) with transpose,* fast activation, but* no chain / song mode etc...
- A division from the global tempo
- A bend effect
- mode of aftertouch chanel : standard, last key, highest key, lowest key...
The layers can be played simultaneously or individually. So you can create 4 layers that plays on The River, the external midi jacks and via CV Gates pilot a Minimoog, plus a paraphonic modular synthesizer and have an arpeggio or sequencer on each layer ....
The River manages 10 profiles of 4 layers.
The River is eight independent analog voices, even the LFO. The schema is basically that of the moog Source that I modernized and completed. Adding FM from VCO2 to filter, PWM, inverted envelopes etc ...
The River is multitimbral, the matrix of buttons on the left allows to assign from 1 to 8 voices to 1 to 8 channels. We can therefore go up to 8 different sounds of 1 voice. If several voices are assigned to a channel, you can select a unison mode and then set the detune to magnify the monaural sound.
8 Independent LFos is wonderful for the PWM , but less practical for a vibrato. DLFO is a digital LFO that is common to every voice in a channel. It has traditional waveforms, plus S & H, Rand, RE150 crying , AR etc ... This digital LFO can be affected by a mix between velocity, modulation case and aftertouch channel.
On the front panel, the functions preceded by an S indicate that the Shift key must be pressed to access this function. Example: shift + rate of analog LFO = analog LFO delay. The River's keyboard handles two velocities: attack and release. With Shift + Attack and Shift + Release, you can adjust the influence of velocity on attack and release of envelopes.
The Triko is a summator for the 8 voices independent tuning of the level and pan for each voice. It is followed by an Analog Triple Chorus (BBD) and an Echo or Digital Reverb with analog routing. The parameters of The Triko are included in the Sound.
The River allows you to memorize 200 sounds but also 40 performances. A performance is a complete picture of The River's settings: setting of each voice, voices assignments, RiverKey settings and Triko settings.
*
Each voice has its own panoramic and level. The summation is then made in stereo to pass in the Tri Chorus (each chorus also having its panoramic and level) then the effect reverb /echo which also has its panoramic and level
Each voice has an individual output. If a plug is inserted into the output, it is removed from the mix.
The Gates CV outputs can emit 1 digital LFO, attack and release velocity, bend, wheel and aftertouch channel. CV is compatible with V / Octave and Hertz / Volt, Gates is compatible with STrig VTrig. Sequencer and arpeggiator can be sent to CVs Gates and CV Gates supports mono, paraphonic and polyphonic modes.
Today there is no synchronisation of the River via CLOCK inputs. Only midi clocks are managed (in and out) and No CV In, just a LFO Out

> Can you tell me how much of the audio path is discrete, and where it becomes digital?
The Audio Path is full analog. I Use digipot for pan and level. The Tri Chorus is full analog, The Echo/Reverb is digital but just the Wet. Routing is analog for Dry and mix wet/dray , feedback.
-
> Is it possibly to bypass/skip the Triko and stay discrete until the outputs?*
Yes, with ouput for each voice.
-
> On the screenshot I do see a CV input, what is this for?
Ruban (pressur control) or CV Pedal "
