New: version 1.1 update adds velocity modulation of the Filter EG . ds80 has been added to the Korg Logue software. This is a wavetable-based user-oscillator with sounds from the Digisound DS-80-21 VCDO , a 1980’s vintage rack module. The oscillator is based on the viper engine, using additive synthesis to generate high quality output without aliasing. Features include wavetable modulation from the Shape control and Filter EG, adjustable table interpolation for smooth or stepped sweeps, a bandwidth limiter, and simulation of analogue control voltage drift.
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.
After ten years running on Wordpress, this site has now been migrated to static HTML using Hugo along with a customisation of the Mainroad theme. The motivation for this was to substantially improve site responsiveness and security, while also simplifying maintenance. Wordpress has become a maintenance headache with constant updates needed for both the core application and plugins. Editing posts and pages has also become more painful than necessary. In contrast, the Hugo static site generator runs locally and generates fixed HTML content.
The phase7 user-oscillator has been released for the Minilogue XD and Prologue. This is a successor to unity, and the oscillator can emulate the Roland JP8000 super-saw as well as a range of other waveforms. The plugin’s architecture is that of a classic super-saw emulator, with seven free-running waveform generators for each of the two oscillators. In a standard super-saw emulation each wave generator will produce a naive sawtooth with a sharp transition that will generate obvious aliasing at the 48KHz sample rate used by the Logue synthesisers.
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.
