The River description
The River = The RiverKey + The River + The Triko
Let's start with the built-in keyboard: a Fatar TP8S, one of the best keyboards to date. Supported by The Riverkey, the keyboard transmits the velocity of attack but also release velocity and a channel aftertouch with a pseudo polyphonic mode.
The Riverkey handles internal keyboard information 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) - Mode A (polyphonic, paraphonic, monophonic) - A transposition (octave / half tone) - An automaton (arpeggio or sequencer) with transposition, fast activation, but no mode chain / music etc ... - A division of the global tempo - Bend, Wheel and channel aftertouch management: standard, last touch, highest key, lowest key ...
The layers can be played simultaneously or individually. Thus, you can create four layers that play simultaneously on The River, on external MIDI jacks and via CV Gates drive a Minimoog, plus a modular paraphonic synthesizer, each layer can receive an arpeggio or sequencer.
The Riverkey manages 10 profiles of 4 layers. Each profile is configurable in a dedicated software and then injected into The River.
The River is an analog polyphonic 8 full multitimbral voice! VCO, VCF, LFO and Envelopes are 100% discrete components, CMS and Through Hole combinations. The River has eight independent analog voices, LFOs and envelopes are also analog. The voice shematic is basically that of a Moog Source that I have modernized and completed: adding VCO2 FM 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. So we can define up to 8 different sounds, each on a voice and trigger the 8 voices individually or simultaneously. If multiple voices are assigned to a channel, you can select a unison mode, and then set the detune to magnify that mono sound.
Eight independent LFos, it's wonderful for the PWM, but less convenient for a vibrato. The River incorporates a DLFO, which is a digital LFO common to all voices of a channel. It has traditional waveforms, plus S & H, Rand, wailing of an RE150, AR. Dosing and / or speed of the digital LFO may be affected by a mixture of keyboard velocity, dial, expression pedal, and aftertouch.
On the front panel, functions preceded by an S indicate that the Shift key must be pressed to access this function. Example: shift + analog LFO rate = analog LFO delay. The River's keyboard manages two speeds: attack and exit. With Shift + Attack and Shift + Release, you can adjust the influence of velocity on the attack and release velocity on the envelope release.
The River can memorize 160 sounds (Singles), 40 Effects alone, but also 40 Multis. A Multi is a complete picture of The River's settings: setting each voice, assigning voice, The RiverKey settings, and The Triko settings.
An audio input is used to insert a mono or stereo line level signal in The Triko.
An integral part of sound sculpture, The Triko is a sum for the independent adjustment of the eight voices: level and panoramic. It is followed by a Triple Analog Chorus (BBD) and an Echo or Digital Reverb with an analog routing. The parameters of The Triko are included in the sound. The dosage and / or the amplitude of certain parameters can be affected by playing informations: velocity, wheel or expression pedal.
I'm Happy ;) Audiofanzine has done a complete test of The River much richer, talkative and sound that these few words. Follow the link;)
