I believe the amps are additive.....if you have an eg at max amplitude
and add velocity or aftertouch ...they increase over the top sustain
level.....As I remember,.if your eg is set all the way down
(shortest)the velocity seems to increase the initial level that the
envelope starts at ...thus the bump from the fastest attack/decay times
would be the full range of the fastest envelope with 0 sustain
superimposed on top the initial level set by velocity......
With respect to the filters.... is it the filters which stop at 12k or
is it the oscillators....
We would need to run some external sources into a m card to really see,
however I do recall hearing some really high pitched frequencys as I was
poking around with the trim pots ov which I collected no samples.....
