ASRs
Late and slow
The two ASRs of a layer: delay, attack and release, the Norm, Hold and Rept modes, what triggers them, per voice or global, and what they drive.
An ASR is the simplest envelope: once triggered it waits, rises to 1 and falls back to 0. Each VAST layer has two, ASR1 and ASR2, and they bring things in late or slowly: a vibrato, a filter, a dip in the level.
Five lessons: the three times, the three modes, what starts an ASR (each note, pressure, the wheel, a pedal, the key's release), the global ASR2 a whole program shares, and where ASRs go.
From the three times to where they go.
Each lesson animates ASRs taken from the factory programs: watch them on the scope, move their times and triggers, and hear what they drive.
An ASR is the simplest envelope: once triggered it waits for its Delay, rises from 0 to 1 in its Attack time, and falls back to 0 in its Release time.
1566 ASRs in 435 factory programsLESSON 2Norm, Hold, ReptModeThe mode decides what happens at the top.
Norm 842, Hold 574, Rept 150LESSON 3What starts itTriggerAn ASR starts when its trigger switches on: ON starts it with every note; a controller starts it when it passes halfway, pressure, the mod wheel, a button or a pedal; Rel State starts it when the key is let go.
1245 ASRs on ON, 321 on a controlLESSON 4ASR1 and a global ASR2ScopeASR1 belongs to each voice: every note runs its own.
68 programs with a global ASR2LESSON 5Where it goesDestinationAn ASR does nothing until a field reads it.
