Adr1 And Adr2; Random Generator - Lexicon MPX 1 - REV 2 User Manual

These ADSR-type envelope generators can be gated on and off via any MPX 1
patch source. Aside from the usual attack, decay, sustain and release param-
eters. The MPX 1 ADRs include additional controls that allow you to further
customize their behavior.
Note that the rate parameters (attack, decay and release) are logarithmic. The
highest value, 100, is very fast (less than a millisecond). The lowest value, 0,
is very slow (more than two minutes). Values above 50 are generally the most
useful unless you are creating effects with control changes that take place over
several tens of seconds.
ADR (1 or 2)
Parameter Range
Mode Off, Once, RTrig, Loop
OnDly 0-100
ARate 0-100
DRate 0-100
S Lvl 0-127
STime 0-100
RRate 0-100

OnSrc Off, On, any internal
or MIDI controller
This controller produces a random stream of numbers whose maximum range
is 0-127. You can limit both the lowest and highest values and control the rate
at which the numbers are generated.

ADR1 and ADR2

ADR Modes
Off: ADR is disabled (OnSrc and
OnLvl are ignored)
Once: ADR completes a full attack,
decay, sustain, release cycle
when OnSrc value rises
above OnLvl. (During the
cycle, further changes of
OnSrc value are ignored.)
RTrig: ADR restarts its attack, de-
cay, sustain, release cycle
whenever OnSrc value rises
above OnLvl.
Loop: ADR repeats its attack, de-
cay, sustain, release cycle
endlessly
