Behringer PROTON - 8 ADSR Envelope Generators; Attack; Decay; Sustain

22 PROTON User Manual
8. ADSR Envelope Generators
The Proton has two entirely independent ADSR envelope generators, which are individually triggered via the In patchbay. ADSR 1 is
normally used to modulate the lters, while ADSR 2 is connected to the VCAs, although this connection can be broken using the In
patchbay; and the ADSR curves are also available to patch into other destinations on the Out patchbay.
8.1 Attack
Each ADSR envelope has an attack time from around 300 µs when the control is fully CCW to 7 s when the control is fully CW, in fast mode.
In slow mode the maximum time increases to 42 s.
8.2 Decay
Each ADSR envelope has a decay time from 2.4 ms when the control is fully CCW to 20 s when the control is fully CW, in fast mode. In slow
mode the maximum time increases to 1 m 56 s.
8.3 Sustain
The sustain level can be adjusted to give no sustain at all when the control is fully CCW to full sustain at whatever level decay falls to when
the control is fully CW, until the key is released.
8.4 Release
Each ADSR envelope has a release time from 1.5 ms when the control is fully CCW to 24 s when the control is fully CW, in fast mode.
Inslow mode the maximum time increases to 2 m. Please note that is sustain is fully CCW then release will not function.
8.5 Fast/Slow
The F/S button allows the ADSR envelope generators to be switched from their normal (fast) mode to slow mode, where times are
extended signicantly. The associated LEDs light to indicate whether either, neither or both ADSRs are in slow mode.
8.6 Retrigger
When retrig is o, which is its default state, any new notes played while a note is held will not cause the envelope generator(s) to break
their cycle. Switching retrig on will cause any new note played to start a new envelope cycle, regardless of whether another note is being
held. Please note that retrigger only works when the Proton is under MIDI control.
