tsoniq fusion pro

fusion is a user oscillator for the Korg Minilogue XD and Prologue synthesisers.

fusion provides a complete virtual-analogue synthesiser, with extensive control from the Prologue or Minilogue XD front panel.

Layer fusion with the standard VCOs to thicken sounds and add sub-oscillators, or use it standalone to provide a complete virtual-analogue emulation of the Logue VCOs but backed with a 24dB/octave filter - all controlled from the main synthesiser panel by mirroring the VCO and VCF controls along with their modulation sources.

fusion provides:

resonant 12/24dB low-pass, high-pass and band-pass filters with key-tracking and EG and LFO modulation from the front panel
accurate emulations of the Minilogue XD VCOs, including shape, sync, ring and cross-modulation
dual oscillators that shadow the corresponding VCO panel controls
a dedicated high-pass trim filter controlled via the multi-engine 'shape' control
an adjustable analogue 'age' controlled via the multi-engine 'shift-shape' control
the ability to use the VCO mixer levels to cross-fade between VCO and the paired digital oscillator

fusion uses a newly developed high-quality audio engine, using 2x oversampling and anti-aliased virtual analogue oscillators, which include:

emulation of the Minilogue XD's VCOs, with all three waveforms, shape modulation, sync and ring modulation
emulation of the Alpha Juno PWM Saw waveform (“hoover” sound)
emulation of the JP8000 super-saw and super-square oscillators
emulation of the JP-4 sawtooth and sawtooth + sub oscillator
pulse and pulse + sub waveforms
phase modulation waveform generators

architecture

Extensive use is made of the synthesiser's front panel controls, making fusion intuitive to use while also providing greater control than is possible with conventional user-oscillator plugins:

fusion provides models of the Minilogue XD VCOs, but with the ability to route the audio through both the VCF and a flexible digital filter – as close as you can get to dropping a 24dB/octave, high-pass or band-pass filter in to your existing instrument.

Demos
