MFB | Synth Lite II


The SYNTH LITE II is the programable successor of MFB´s popular SYNTH LITE. This monophonic synthesizer offers three digital oscillators, external audio input, analogue lowpass filtering with 24dB/oct and an analogue voltage controlled amplifier. 

The SYNTH LITE II is equipped with MIDI and offers 83 memory locations. MFB has even integrated a programable step sequencer. Here are the details: two main oscillators each offer sawtooth and square. In addition, OSC 2 can be set to generate an impulse waveform. Ring modulation is possible, as well as syncing OSC 2 to OSC 1. Each oscillator´s octave range can be set to 4', 8' or 16'. OSC 2 can be further detuned over a range of plus or minus one octave. 

The voltage controlled filter (VCF) offers 24 dB/oct lowpass filtering. EMPHASIS (resonance) can be set up to self-oscillation. An external audio input is also routed directly to the filter. Both the voltage controlled filter and the following voltage controlled amplifier have dedicated envelope generators with Attack, Decay, Release and Sustain parameters. Decay and Release share a control and are selected by a switch. 

The SYNTH LITE II´s LFO can modulate the oscillators´ pitch or the filter cutoff frequency. Pulse width modulation for OSC 2 is also possible by setting its waveform to Impulse. A glide function can be activated with different speeds to achieve popular portamento effects.

MIDI data is received as note on/off, pitch wheel (+/- 2 semitones) and mod wheel. Velocity can be routed to VCF and/or VCA, alternately it can be disabled. The sequencer is programed from a MIDI-keyboard. Its resolution is 16th notes with up to 32 steps. Pause notes can be set as well as external synchronization.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
