S/H; Env1 And Env2 - Lexicon MPX 1 - REV 2 User Manual

The sample and hold controller is similar to functions found in many synthesiz-
ers. Its output is derived by "sampling" the value of an input signal.The MPX 1
version allows you to select any controller as the input signal, and also allows
you to select any controller to trigger the sample.
A typical use would be to use LFO1 Sine as the input signal and LFO2 Pulse as
the sampling clock. With both LFOs set to different rates, the output will be a
constantly changing staircase pattern. Before you decide that this is too techno
for you – be sure to listen to the presets 50's Sci Fi and Synthis Izer!

Env1 and Env2 are two identical envelope followers which create an output that
varies with the level of the Src parameter. For each envelope follower you can
choose any two audio level as sources. To follow the levels on both main inputs,
set Src1 to Left Input and Src 2 to Right Input. Use Resp and ATrim to customize
the response to level changes. Note that these controls are logarithmic. Resp
values below 50 take many seconds to "catch up" with audio level changes. For
most situations, you'll find values above 50 to be the most useful.
