Lazer Storm Preset - What Osc is Sound Source?

Post by mylkoa » Tue Sep 27, 2016 8:16 am

Hello!
I am looking at the preset "Laser Storm"... it is a factory preset, in the "Single Zone>FX" section of the presets, when browsing.

I am looking at the synthesis view, and all the faders in the Source Mixer are turned down for all four oscillator types (square, sawtooth, sub, and noise)...so where is the sound coming from? I must be missing something...

I'm loving these presets, and studying them is very helpful to my understanding of synthesis

Thanks :)

Hi,

This is a trick involving filter's self-oscillation. If resonance is high enough the filter is capable of generating sound alone (without any external sound source fed into it). Then sound's pitch is controlled by a filter's cutoff.

In the preset you mention try to decrease Resonance parameter and you'll hear the sound will be gone.

Kind regards,
Sebastian
