ENV2 and ENV3

ModulationENV2 · ENV3 · −100 to +100 %

ENV2 and ENV3 shape something other than the loudness: a filter's frequency, the pitch, a level, a FUN. They are bipolar, from −100 to +100 %, move in straight lines, and do nothing until a field reads them with a depth.

WHAT TO KNOW

THE FIELDS

The ENV2 and ENV3 pages, seven segments each like the AMPENV's; their Rel3 keeps a level of its own. A field reads them as Src1 or Src2, with a depth in its own units.

RANGE

−100 to +100 %: below 0 the destination moves the other way, a filter closing below where you set it, a pitch falling.

USE IT FOR

ENV2 on a lowpass filter's frequency, the classic filter envelope; on the pitch for a blip or a fall; on AMP as a second loudness contour; ENV3 on a second filter or an EQ.

WATCH OUT

The depth sets how far: an ENV2 at 100 % with a depth of 4800 cents opens a filter four octaves. In KOACH the envelope control and Impact act on the AMPENV only.

IN THE FACTORY PROGRAMS

ENV2 in 2491 layers, ENV3 in 912. 1097 ENV2s go below 0 somewhere. ENV2 on a 2POLE LOWPASS's frequency (Src2) has a median depth of +4500 cents.

HOW TO ON YOUR K2700 · 829 Cirque du Synth

Cirque du Synth's ENV2 opens and closes a lowpass filter. See its shape, then where it goes.

  1. In Program mode choose 829 Cirque du Synth (KEYPAD, 829, ENTER).

    Program mode with 829 Cirque du Synth
  2. Press EDIT, then MORE and ENV2. It jumps to 100 %, falls to 7 % in 0.34 s, swells to 83 % in 1.4 s and settles at 66 % in 3 s.

  3. Where it goes: MORE, DSP MOD. On the LP Frq row Source 2 is ENV2, its depth from 0 ct to 4800 ct as FUN1 rises: the filter follows the envelope.
