Does anybody know whether a DirectX plug-in exists which
acts like a LPF/HPF filter, possibly controlled via the
envelopes in ACID Pro. If not, is there any way you can
emulate filter sweeps with Hyperprism or DSP plug-ins, etc.?

Get the Waves Native Powerpack. It's a set of DirectX plugins that
not only contains 10 different EQ filters (for excellent
lowpass/highpass effects) but a lot of other useful pluggies as well.
You can read more at

www.waves.com

I've been using it for a while now and it still rocks!

Thanx 4 the tip ATP, i'll surely give it a try. Not before you guys
out there try 2 answer this one though...
I would like to emulate those wild filter sweeps so beloved of
producers such as DJ Sneak and other House producers of his ilk. Now
how do i get to make the envelopes in say, FX1, to work like i'm
sweeping the filter thru 8 bars from 0 to 127 (cutoff)? The envelopes
in ACID seem 2 b more at home emulating the equivalent of FX gain
pots than TB303 cutoff/resonance knobs. Get my drift? I hope you do,
as this query is bugging the hell out of me....

Well, I hope I understand you correctly, but the envelope for an
effect (i.e. FX1) should in operation be the same as a normal volume
envelope.
Just click on the event you wish edited and press F (for FX1). An
envelope will appear. (You can also right-click on the event and
select an envelope). Remember that you can add points anywhere in the
envelope line.

Now you could, for example, drag the first point of FX1 all the way
down and make another one at the end, which stays at 0 db. Then, in
the same event, create a volume envelope (or another FX env.) Now do
the opposite, i.e. dragging the LAST one all the way down and leave
the first one up.

This will create a nice crossfade from the normal sound to the sound
as it goes through FX1.

Again, I don't exactly know if this is what you mean...but if it
isn't, then I suggest you just freak around with ACID. Click on
something and watch what it does. ACID is easy and very intuitive,
and I'm sure you'll get the hang of it in no time!

Well ATP, thanx again 4 your help, but i'm afraid that what i feared
is actually true, i.e. the FX1/FX2 envelopes are simply effects gain
pots, thus leaving the frequency of the plug-in fixed and not
variable. The only way i can seem to achieve this filter sweeping
thang is to go to my mate's place, download the particular loop on
his sampler, pass it thru the filter and record it back as a .wav
loop, then use it in ACID...a real pity, as so far ACID has been
nothing short of revolutionary. I shall try what you suggested,
though.

Thanxalott!

Nope, can't do this. What you basically want is automation control
over fx parameters.

This is not a limitation of ACID but rather a limitation of the
plugins. There is currently no way for an application to get at the
individual parameters of a plugin. The internal configuration of any
given plugin is opaque to the application.

Sonic Foundry has proposed a standard to allow for this and Microsoft
has indicated that this will be addressed in an update to the
filter/plugin model. As soon as there is a standard, we will adopt it.

Ok Jason, I finally understand what you'd want with ACID ;-)
And indeed, to change the frequency of the FX filter is not possible
the way you want it to do.

You could (although this is very inefficient and it needs a powerful
computer) create multiple FX effects that and change the frequency of
each a bit. Then, crossfade the loops as I described before and
you'll have some sort of a filtersweep.

But, once again, this is not the best way to do this. I think using
your friend's sampler is faster and less demanding of your PC.

Good luck!
