Triple Attack Release Generator
You can never have enough modulation sources so that's why EMW created the AR 3X: a versatile module that can produce up to three independent linear Attack-Release envelopes.
Each envelope generator has its own Attack and Release controls and a LED indication that lights according to the envelope intensity.
Like all EMW modules, the AR 3X works with 2.5 to 15V Gates or Triggers signals.
