Korg Minilogue-XD

Additive synthesis on a CPU and memory constrained ARM platform

Additive synthesis on a CPU and memory constrained ARM platform

The Korg Prologue and Minilogue-XD feature the ability to load digital user-oscillators that extend the range of possible sounds. Good candidates for these are emulations of oscillators from early digital/analogue hybrid synthesisers, replicating waveforms and wavetables from instruments such as the Korg DW-8000 , the Kawai K3 , the Ensoniq ESQ-1 and PPG Wave . But, there is a catch. Logue plugins run on a relatively slow processor, an ARM Cortex M4, with only 32KiB of shared code and data space.

fusion: a user-oscillator for Prologue and Minilogue XD

The new fusion plugin for Korg Prologue and Minilogue XD has been released. This uses a newly developed virtual-analogue synth engine, which runs on the Logue’s Cortex M4 oscillator CPU. The engine combines high-quality anti-aliased oscillators with true 2x oversampling for the best possible audio quality. fusion attempts to answer the question: can I put a 24dB/octave filter in my Logue? Changing the VCF is not viable, so fusion aims to be the next best thing: a user-oscillator that provides virtual analogue models of the Minilogue XD VCOs combined with a multi-mode digital filter.
