FEATURES OVERVIEW
At its core, AIRSTREAMER 4 is an AD / ASR envelope with a VCA control and
looping functionality, capable of processing external CV sources by acting as a slew
limiter , S&H and T&H .
Onboard AMP – polarizer knob lets you attenuate and invert the envelope on the fly,
feeding negative voltages to the VCA input will offset the envelope up by +5V and
invert it, allowing for a compact sidechain envelope solution without the need for
external mixers, inverters and offset generators.
The
DECAY / RELEASE time can be modulated with external CV sources and END
OF CYCLE output can be utilized to trigger additional envelopes / sequencers /
voices in your system, extending the interconnectedness of your patches.
Looping mode allows the envelope to cycle from slow
LFO rates up to audio rates.
Coupled with 1V/OCT INPUT the envelope turns into an oscillator, level of which
can also be adjusted using the built in VCA – either controlled manually or with
external CV, which can be very handy when using AIRSTREAMER 4 as a
modulator
oscillator for FM patches.
Continuously variable shape over both slopes adjusts the curve / tonal content of
the envelope / oscillator without stretching slope’s duration in time, making the
module easier to use in a variety of musical applications.
SPECIAL OPERATION MODES
T&H: TRACK AND HOLD
The following mode is selected by setting the MODE SWITCH (8) to the middle
position. Feed external audio or CV source to the 1V/OCT/slew* input jack (2) and
freeze them by applying the positive gate input into TRIG/GATE jack (1).
TRACK & HOLD mode continuously samples the external signal and once a trigger /
gate goes high on the TRIG / GATE input (1), it will freeze / hold its momentary
voltage level until the trigger / gate goes low again.
S&H: SAMPLE AND HOLD
The following mode is selected by flipping the MODE SWITCH (8) to the right. Feed
external audio or CV source to the 1V/OCT/slew* input (2) and ‘sample’ their
momentary voltage levels by applying the positive trigger or gate into TRIG/GATE
jack (1).
Unlike
T&H mode, SAMPLE AND HOLD does not continuously sample the external
CV / audio source, but only starts to sample the signal once a first trigger or gate
