ASR-10 Envelopes
Each ASR-10 WaveSample has three envelopes. These envelopes are hard-wired to the pitch,
filter cutoff frequency, and amplitude of the WaveSample. Env 1 and Env 2 can also be assigned
elsewhere, wherever a modulator is selectable. Each of the three envelope buttons is directly
above the page button for the function it’s associated with:
• Env 1 is routed to WaveSample pitch.
• Env 2 is routed to WaveSample filter cutoff frequency.
• Env 3 is routed to WaveSample amplitude (volume).
The indicator lights in the display tell you which one of the three Envelope pages you are on. For
example when you are on the Edit/Env 2 page, the FILTER and ENV indicators are lit.
About ENV 3
In the ASR-10, the response of the WaveSample volume, ENV 3, and the Instrument mix level all
use the same (non linear) response curve. As shown below, setting any of these volume controls
to 50 will attenuate a sound by 16 dB.

The ASR-10 envelope is a descendant of the venerable ADSR (attack, decay, sustain, release)
envelope, with a number of refinements. While the ADSR envelope gives you control over three
times segments and one level, the ASR-10 envelopes have six times and six levels.
What’s more, the envelope parameters allow you to describe two entirely different shapes; one
for maximum velocity (HARD VEL) and one for minimum velocity (SOFT VEL). When a key is
struck, the envelope generator actually interpolates between the two, creating a curve that is a
combination of the two based on the incoming velocity.
