General
MFB SYNTH PRO is a synthesizer with eight voice polyphony. Its
analog sound engine is based on circuits and techniques which
have been used in synthesizers of the 70s and 80s and have been
updated and expanded by useful functions. Among the special
features of SYNTH PRO are the oscillators which can seamlessly blend
between waveforms. The VCOs can alternatively being used in a
DCO-mode. The filter section offers two separate VCFs (per voice)
with different characteristics which can be coupled to be controlled
simultaneously. In addition, SYNTH PRO offers 240 storage locations, a
polyphonic sequencer, an arpeggiator, extensive controllability via
MIDI-controllers and a digital effects processor.
Starting up
SYNTH PRO is powered by an external power supply which is
connected to the
6V/1,5A
jack on the unit’s rear panel. Find the
POWER ON/OFF
located alongside. Prior to switching on the device,
connect the
AUDIO OUT
jack to a mixing console, an audio-
interface or an amplifier. Switch SYNTH PRO on or off using the
corresponding switch.
SYNTH PRO can be played by a keyboard or an external sequencer
using the MIDI protocol. To do so, connect the
MIDI IN
input or
USB
KEYS
to the MIDI-output of a keyboard or to a MIDI-interface of a
computer running a DAW.
Hint
: Since SYNTH PRO is an analog synthesizer, you should always
allow a warm-up-period of approx. five to ten minutes to achieve
tuning stability.
Presets that have been programmed using the VCO-mode may
sound detuned or “strange” compared to the stored version during
this period. For this period, but not only for that, SYNTH PRO offers the
option to switch to DCO-mode which is always stable in tune.
In case, FM has been used in a preset, make sure the operating
temperature for the circuit has been reached since FM is not
available in DCO-mode.
