Modifying ADSR parameters of all MIDI notes at once?

Hello everyone,

I use a VST that doesn’t support ADSR modification out of the box (Spitfires Symphonic Discover), is there a way to use a VST as Insert effect or something to still modify the MIDI ADSR curve? (to give e.g. all MIDI notes a slow attack, and a sudden release)

Or could you adjust the MIDI note ADSR curve afterwards somehow?

MIDI Notes don’t contain any ADSR information at all. ADSR is entirely under the control of the Instrument.
