The MFB-POLYLITE is a MIDI-controlled four-voice desktop synthesizer. Each of its four voices offers three flexible digital oscillators, analogue 24 dB low-pass filtering (VCF) as well as an analogue amplifier (VCA). The MFB-POLYLITE offers 100 memory locations for total recall (except Tune). Editing is done by standard MIDI controllers, a free Editor software or, ideally, a MFB-SYNTH LITE II since the MFB-POLYLITE has no controls by itself.
Both main oscillators offer switchable square and saw tooth waveforms (the saw tooth was improved), as well as ring modulation for OSC 1 and an impulse waveform for OSC 2. In addition OSC 2 can be hard synced to OSC 1, too.
The octave range is switchable between 4’, 8’ and 16’ with an additional detuning range of plus minus one octave for OSC 2. The sub oscillator is fixed to 32’ and uses a square wave that can be controlled in level and fine tuning. The filter is an approved 24 dB low-pass design with resonance up to self-oscillation – its cutoff frequency can be modulated by different sources. VCF and VCA offer individual envelope generators with Attack, Decay, Sustain and Release parameters. Decay and Release either share a single control or, alternatively, Release may be switched off. Further modulations are performed by an LFO with One-Shot function. The LFO addresses oscillator pitch, pulse width or cutoff frequency.
Glides between legato played notes can be performed in three speeds.
MIDI-data processed are Note-On/Off, Pitch Wheel (plus minus 2 semitones), Mod-Wheel and additional Controller Data; Note Velocity can control the VCF as well as the VCA.
Preset programming is ideally performed from a MFB-SYNTH LITE II. A free Windows Editor software is ready for download here:
