The Envelopes 
 
If you hit a note on a piano, you’ll hear a burst of sound energy as 
the hammer strikes the string, followed by lower level of loudness 
as you hold down the note and let the string ring out, which fades 
quickly as soon as you release the note and the damper is applied.  
Synthesizer designers model this behavior using ADSR envelopes.  
ADSR stands for “attack, decay, sustain, release”, and represents 
the different stages that the sound goes through over the life of the 
note.  Since the most important application of the envelope is to 
control the loudness of the sound, the Micron provides one 
envelope that is specifically designed for this purpose.  This is the 
amp envelope.  However, envelopes are useful in all sorts of mod 
routes, which is why you can hook up any of the Micron’s 
envelopes to any modulatable program parameter.   
 
Each of the Micron’s voices contains three envelopes.  “Env1” is 
the amp envelope.  “Env2” is the filter envelope.  “Env3” is the 
pitch/modulation envelope.  
 
 
 
 
Playing Programs 
 
 
Press the [programs] button to enter programs mode. Release the 
[programs] button and spin the control knob to cycle through 
the programs first by category and then–after you have reached 
the last program within the last category–again in alphabetical 
order. 
 
You can also quickly switch to any category by holding down 
[programs] and then pressing the white key on the Micron’s 
keyboard labeled with that category.   
 
Note that the “recent” category is generated automatically.  The 
“faves” category is controlled by you, as detailed in the next 
discussion. 
 
Envelope assignments 
Envelopes can affect different 
parameters depending on the 
modulation routes you assign.
