Understanding envelop time quick edits

2013-12-13 by <ricard2010@...>

There's something I've been wondering about for a while: When editing envelope time parameters, such as attack or decay, a value of 0 means 'instantaneous', whereas higher values result in longer times.

However, when setting up a patchcord in order to map a MIDI controller (i.e. quick edit knob) to an envelope time, the resulting 'amount' value is normally set to a negative number. This results in a knob position of far left giving a corresponding time of 0, and advancing the knob results in longer times, as would be expected. What I don't understand is why the patchcord amount in this case must be set to a negative number; that would tend to shorten the corresponding time parameter rather than lengthen it I would have thought.

Is there any explanation for this?
