FMonsta by DirtBoxSynth is a custom FM oscillator pack for the KORG Prologue Synthesizer that lets awake its powerful customizable multi-engine.
At the NAMM 2018, the new KORG Prologue hardware analog poly Synthesizer was introduced with big anticipation. Many were disappointed because the instrument has only one LFO or no sequencer on board. For me personal, the most exciting point of it is the user-definable digital multi-engine with which you can do a lot.
Now after a few months on the market, the first third-party company has developed a new oscillator section for the multi-engine using the SDK. FMonsta is an oscillator pack that is based around wavetable and phase/frequency modulation techniques. Each pack features a selection of parameters that gives you freedom to play around with the new engine.
Per example: the FMonst has a loopable envelope while FMonst 2 includes an internal LFO and distortion. With these packs, you can easily expand the sound range of the Prologue Synthesizer. Hopefully it’s just the beginning of several new oscillator and effects engine.
Beside this the developer also released a free ModFX expansion for all KORG Prologue Synthesizer user. The DirtBoxSynth Classic Panner is a basic autopan effect for the custom Mod Effect user slot.
The FMonsta Pack (1 & 2) is available now for £20 on the DirtBoxSynth website. The developer will require the Prologue serial number to enable to deliver the customer oscillator engine. The AutoPanner for the ModFX is available for free for all Prologue customer.
