Architecture
The
Mono/Fury
features four band-limited oscillators (
VCO
), each with four selectable
waveforms (triangle, sawtooth, pulse with modulated and fixed width), four octave
ranges (16' to 2'), 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-synchronized as
well as frequency-modulated by the VCF EG or the first modulation generator (
MG1
).
MG1 features four waveforms (triangle, falling and rising sawtooth, 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.
Key Assignment Modes
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.

Mono/Fury
are not
voltage-controlled in the same way as in analog synthesizers, but I will stick to this neat
old-fashioned acronyms.
