Oxi Instruments Coral Synth Voice

With Coral, OxiInstruments presents the most complex synth voice module in the Eurorack world. Thanks to plenty of computing power, the purely digital module is capable of ten sound generation forms and can be played polyphonically in 8 voices. Each of the eight voices consists of the selected engine, a separately adjustable noise generator, followed by a lowpass filter, a VCA with panning and an insert chorus effect, which can also be an optional Highpass Filter. The filter and VCA are equipped with their own attack/decay envelope. Subsequently, all voices are summed and, if required, run through an incredibly deep and detailed-sounding master reverb effect.

A pure administrative act

If Coral is operated in a classic modular context, nine control voltage inputs control all sound-determining parameters. The CV input "Part" controls which voice or voice combination is currently addressed by the analogue inputs. Due to the complexity of Coral, it is advisable to play the module via MIDI. This is where the full potential of the Synth Voice unfolds: the eight voices can be distributed over a maximum of eight parts. With eg. two parts with four voices each or four times monophonic plus one 4-part, the polyphony is distributed in a matching way and "used up".

Further features

So that you don't have to start from scratch every time, there are ten memory locations for preset configurations. Each voice or grouped voices have their own MIDI channel and there is also an extensive MIDI implementation that enables control via MIDI CCs or a master sequencer such as the ONE. Coral is also MPE MIDI compatible and can be controlled with polyphonic Aftertouch.

10x sound generation

The core of Coral are of course the ten engines, which have very different sounds. What all engines have in common is the structure of the voices. Specific characteristics are set using the Harm, Timbre and Morph controls.

Virtual Analog - two tunable VA oscillators with variable waveforms. The second oscillator runs with hardsync
Waveshaper - an asymmetrical triangle processed by a Waveshaper and a Wavefolder.
FM - two sine wave oscillators that modulate each other in the Phase.
Wavetable - fades through waveforms in X/Y/Z manner
MDO - an 8-fold supersaw oscillator, can morph between saw, square and PWM
String - digital string/resonator modelling
HiHat Synth - two hi-hat models merge together
Snare Synth - two analogue snare drum models merge together
Kick Model - two digital kick/bass drum emulations merge together
WAV Player - contains 10 sets with 32 samples each, 1 sample per voice assignable; eg. 4 voices = 4 samples
