1.
TRIG / GATE / RESET JACK INPUT:
multifunctional
pulse input.
Typically expected 0...+5V or 0…+10V with 0.65V threshold. Use external
triggers to start the envelope in
AD
mode when (8) set in the middle. To have an
additional
sustain
stage, set the envelope mode to
ASR
with (8) to the right and
send a gate signal to this input: gate’s duration will now control the duration of
the sustain stage. When the AIRSTREAMER 4 is set to looping / cycle mode with
(8) to the left, this input will act as a
HARD SYNC
input for the looping envelope,
which works as an oscillator. Additionally, this input acts as a trigger for the
S&H
/ T&H
, allowing you to sample external CV / audio fed to the 1v/oct jack input (2)
see
SPECIAL OPERATION MODES
below.
2.
1V/OCT JACK INPUT
used for controlling the time of both envelope’s
slopes or pitch of the oscillator using external CV, typically 1v/oct signals
coming from a sequencer, but not limited to only that. Additionally, you can feed
it CV or audio source that will be sampled when a trigger / gate goes high on the
TRIG / GATE INPUT
(1). When no trigger / gate is present on the
TRIG / GATE
INPUT
, an envelope follower is extracted from the audio sources fed to the
1V/OCT INPUT
(2).
3.
AMP KNOB:
polarizer / attenuverter controlling the level / polarity of the
envelope / oscillator at the outputs or the result of processing external CV /
audio sources. Sums with bipolar
VCA IN
jack (10).
4.
EXP / LOG TRIMMER
continuously defines the shape of the envelope’s
slopes without stretching them in time: from exponential – to linear – to
logarithmic shapes. So far, generated envelope looks like:
when trimmer is
at full CCW
EXP
position,
in the middle noon position and
at full CW
LOG
position.
5.
RISE KNOB
controls the length of the
RISE / ATTACK
stage of the envelope
or the oscillator in the range from one millisecond to 10 seconds.
6.
FALL KNOB
controls the
FALL / DECAY OR RELEASE
of the envelope in the
range from one millisecond to 10 seconds. Acts as attenuator when a patch
cable is inserted to the
FALL CV
jack input (7).
7.
FALL CV JACK INPUT:
external voltage control for the
FALL / DECAY OR
RELEASE
of the envelope, expects a voltage in the range of 0…5V. Normalled to
+5V when no patch cable is inserted.
