From: Chris Holt <amiga2k_at_cox.net>
Date: Mon, 20 Jan 2003 23:13:58 -0500 From the manual: Auto Volume (Recorder only) Auto volume is a feature that automaticly lowers the volume on loud parts, and then slowly restores the volume to the previous level during N seconds. That N time is configurable here. This would not help me with overly quiet tracks.
