Full Bucket Music: Mono/Fury

German programmer and software engineer Björn Arlt began building VST plugins under the name Full Bucket Effects in 2010. Being a musician, and a synth enthusiast from a young age, he was drawn to analysing and building software synths. He now offers both synth emulations and effects as freeware through his website.

The Mono/Fury is a software synth plugin that simulates the classic KORG Mono/Poly analog synthesizer of the early 1980s. The Mono/Fury features four band-limited oscillators (VCO1), each with four selectable waveforms (triangle, sawtooth, pulse with modulated width, and pulse with fixed width), four octave ranges (16′ to 2′), and individual tuning and volume controls. The VCOs and an optional white noise generator feed a classic four-pole low-pass filter (VCF) with resonance up to self-oscillation. Two envelope generators (EG) control the contour of the filter cutoff and the amplifier (VCA) respectively.

In the Effects section, the VCOs can be cross-modulated and/or hard-synchronised as well as frequency-modulated by the VCF EG or the first modulation generator (MG1). MG1 features four waveforms (triangle, falling and rising sawtooth, and square) and is also capable of modulating the overall pitch, the pulse width of the VCOs, and the VCF cutoff frequency. Modulation generator 2 (MG2) produces a triangle waveform used to modulate the VCOs’ pulse width. Additionally, it is used to control the speed of the built-in arpeggiator. The latter offers three modes (up, down, and up & down), three key ranges (1, 2 or 4 octaves), and can be latched.

Although the Mono/Fury is a monophonic instrument, it offers two ‘polyphonic’ keyboard modes where the VCOs can be played individually (resulting in a four-voice ‘pseudo-polyphony’; mind that there still is only one VCF and only one VCA). Furthermore, the Chord Memory mode allows to play a chord of up to four notes (one per VCO) by a single key. This function compensates the lack of a dedicated control for interval-tuning of the VCOs.
