Slow attack/release (AMP_ENV use)

▸What it is

A slow attack and slow release on the amplitude envelope turn an oscillator into something that breathes — fading in over hundreds of milliseconds or seconds, holding, then fading back out. It is the same envelope shape used everywhere else, just with the time knobs cranked. Pads are almost defined by this setting: the slow attack means notes do not stab in on the beat, they emerge. The slow release means notes overlap with whatever comes next, creating a continuous wash of sound. The trade-off is rhythm: slow envelopes are deliberately bad at being percussive. Anything that needs to land on a beat needs a fast attack instead.

▸Questions

• How slow is "slow" for a pad attack?

  300 ms to 2 seconds is normal pad territory. Past 2 seconds and the note may not be fully audible before it ends, depending on the phrase.

• Will a slow release cause notes to clash?

  Yes — that is part of the sound. Pad releases of 1–4 seconds blur consecutive notes into a continuous chord wash, which is usually the goal.

• Can I use slow attack on a bass?

  Generally no. Bass needs to land on the beat; a slow attack pushes the apparent timing late.
