Low Pass Gate?

[expermusic]

Does anyone know of a way, or perhaps an patch that enables low pass gate-like functions?

Thx!

It is obviously morethat just CVing a low pass filter and amp at the same time. How can I emulate the vactrol responses?

I'd try a lag/smooth module for vactrol response, or maybe two to get a faster on response and a slower off response.

Hmm .. just tried that - too complicated ;-)

Here is another idea :



seems to work sorta nice.

Jan,

Interesting patching.

I notice the keyquant turns the audio rate signal to a control one, I didn't know that it did that.

So if I get this right, the gate signal gets low passed, effectively smoothed and then sampled at the lower control rate (as you don't need it audio rate). Then acts as a envelope signal for the osc and the low pass filter? So presumably increasing the resonance on the first filter would increase the release? How could you control the sustain level or is this not usually possible with a lpg?

Also why is the constant used to pull the cutoff below minimum? Does that work?

Cheers

I now wonder why I didnt just pick an envelope module ..

Yes, the quantizers can be used as blueifiers, and yes most modules will modulate below the minimum value set by knobs.

A vactrol is an LED that shines on an LDR, light = low resistance, no light is high resistance. LDRs tend to be slow, and tend to go to low resistance faster than going to high resistance. The pitch modulation from the gate (to the very low frequency filter) does this in the example above.

Well, anyway, at least it had some novelty to some

hehe.. had a play around with this last night and I really couldn't tell the difference between using your lovely vactrol emulation (Jan) and a normal envelope. Could well be my ears though, they are crap.

Set the filter Q a bit higher, it'll then overshoot and undershoot.
