UniSyn
Universal Audio to Synth Interface User’s Manual
Congratulations for purchasing a Second Sound UniSyn Audio to
Synth Interface! Here is a summary of what your UniSyn can do:
•
Convert audio from any monophonic source into sine and
low-pass-filtered square or sawtooth waves, optionally pitch-
shifted over a ±2 octave range and with semitone resolution
•
Apply envelope modulation of the built-in Voltage-Controlled
Filter (VCF) with three modulation depth settings: no
modulation, full modulation, and half depth modulation
•
Convert audio to pitch, envelope, and gate control voltages
(CVs) for controlling analog synths
• Convert audio to MIDI for controlling digital synths
•
“Hold” the pitch and envelope of both the internal synth
voices, CV and MIDI using an optional sustain pedal (not
included)
•
Provide a 1v/oct FM CV input for modulating the pitch of the
internal synth voices as well as the CV and MIDI outs
•
Provide capability to blend the internal synth mix of sine and
square/sawtooth waves with the dry preamp output
•
P24v phantom power according to the IEC 61938
Standard for powering condenser mics
•
Provide automatic gain control (AGC) over a 50dB range,
yielding optimal preamp gain independent of source signal
level
•
Provide an audio preamp output at 4dBu or -20dBu
•
Optionally configure the AGC/preamp as an upward
compressor with 3:1 compression ratio and threshold of
-12dBFS, with attack time approaching zero and release time
approaching 2 audio cycles
•
Track the fundamental frequency of audio sources as diverse
as voice, guitar, bass guitar, violin, trumpet, saxophone with
minimal configuration required
