MFB - Synth Pro

The Synth Pro is an eight-voice polyphonic analog synthesizer reminiscent of classic vintage instruments. The synthesis structure consists of three VCOs / DCOs plus sub-oscillators, a -24 dB lowpass and a -12 dB multimode filter, two VCAs and a multi-effects section. Furthermore, there are three envelopes and two LFOs. An arpeggiator and a polyphonic step sequencer are included as well.

The Synth Pro is a subtractive poly synthesizer with eight voices. The instrument offers the following core features:

• Three oscillators, switchable between VCO and DCO operation
• Waveforms: Sawtooth, triangle, sqaure / pulse
• Ringmodulator and noise
• Sync and FM functionality (VCO mode only)
• Three sub-oscillators
• SSI-2144 low-pass filter with a slope of -24 dB per octave
• -12 dB OTA multi-mode filter with low-pass, high-pass and band-pass modes
• The filters can be used in parallel or in serial
• Two OTA-based VCAs
• Two LFOs with sawtooth, square, triangle and random waveforms
• Both LFOs have a one-shot mode
• Two ADSR envelopes with loop function
• One ADS(R) envelope with loop function
• Effect section with several algorithms including reverb, delay and chorus
• All parameters can be saved in presets
• Arpeggiator
• Polyphonic step sequencer
• Sends and receives MIDI CC commands
