how do you filter (frequency) samples in realtime

Postby j58 » Wed Dec 03, 2003 3:42 am



I need to figure out how to activate the frequency filtering in real time.
(like the filtering used in d'n'b tracks)

What parameters are needed to be set on the sampler
and how are they activated in the sequencer? (cubase sx)

I know its a noob thing to ask! but help... :P

Well, you're going to have to read the manual, and read it well. Especially the part about Preset Editing and cords.

But, here's a quick guide:

-Get a nice long sample sample, put in in a preset. Assign that preset to a MIDI channel
-In Preset Edit, select the voice, and hit Edit Voice.
-Go into Amp/Filt and hit right twice.
-You'll be in the filters page, and see 2-pole Low Pass, with cutoff set at 20000 and Resonance set to 0.
-Turn the Cutoff to 0.
-Hit right again, you'll see the filter envelope. Change Atk2 to, say, 50.
-Now, go to Cords. You'll see six entries. CO5 will say FEnv+ -> 0% -> FilFreq (or something like that - I can't believe I forgot!)
-Play the note.

You should hear the Filter open up over time.

What you've done is turned the cutoff all the way down, then chosen to have the Filter Envelope modulate it fully (that's waht the 100% means). The Cords allow you to do much crazier modulations than this.

This is really basic, and you do have to read the manual, but this is a good example (I hope) of the way the Filters and cords interact.

Hmm, I typed all that, then realized you may have meant actual real-time, like twisting knobs real-time.

For that, you have to know the MIDI CC# of the knob you're twisting.

Then, in the Emu, hit Master - Setup - MIDI - next - next (again, I think this is right - my sampler's not in front of me). You should be in a screen called Controllers. Set MIDI A to whatever the CC# is of the knob you want to twist.

Now go the Cords in Preset Edit, and select Source as MIDI A, amount 100%, and destination as FilFreq.

Play, and twist away!

(I've had way too much coffee and need to shut up now).
