ADSR Envelope Generator
The ADSR (attack, decay, sustain, release) Enve-
lope Generator controls Bruno’s amplitude en-
velope. This amplitude envelope is applied to a
sound each time a note is struck.
The four envelope elements can be adjusted by
dragging the appropriate breakpoint, or by typ-
ing in a numeric value.
Attack
Controls the amount of time in millisec-
onds that the sound takes to rise from zero am-
plitude to its full level. The longer the attack, the
more time it takes for the sound to reach maxi-
mum volume after the a note is struck. This con-
trol is adjustable from 0.0 to 5000 milliseconds.
Decay
Controls the amount of time in millisec-
onds that the sound takes to fall from its peak
Attack level to the Sustain level. This control is
adjustable from 0.0 ms to 5000 ms.
Sustain Level
Controls the amplitude level in dB
that is reached after the decay time has elapsed.
The amplitude level stays constant as long as a
MIDI note remains depressed. This control is
adjustable from –96 dB (no sustain) to 0.0 dB
(maximum sustain).
Release
Controls the amount of time in milli-
seconds that the sound takes to fall from the
Sustain level to zero amplitude after a note is re-
leased. This control is adjustable from 0.0 ms to
5000 ms.
Bruno Pitch Controls
Glide
Glide, also known as portamento, determines
the amount of time it takes for a pitch to glide
from the current note to the next note played.
This effect is commonly found on synthesizers.
Glide is adjustable from a low of 0.0% (no glide)
to a high of 100% (maximum glide). A setting of
100% will take the longest time to travel from
the current note to the next note played. The ef-
fect is also dependent on the interval (distance
of pitch) between the two notes: The larger the
interval, the more noticeable the effect.
Bend Range
Bend Range sets the maximum interval of pitch
bend that can be applied to Bruno with a MIDI
controller’s pitch bend wheel. This control is ad-
justable from 0 semitones (no bend) to 12 semi-
tones (1 octave).
Master Tune
Master Tune can be used to tune the pitch of
Bruno’s output to another instrument. By de-
fault, this control is set to 440.0 Hz It can be ad-
justed from a low of 430.0 Hz to a high of
450.0 Hz.
