Addition:
If you use the A-140 to "pitch shift" the oscillators there will be a
drop when the sustain level is reached. you won´t notice if you use
the eg for other things but it is rather dominant when used with
pitch. (The 141 doesn´t do this -Dieter says). The work-around is to
use the slew limiter as an Eg - if you do not have the 141
