A dated but interesting look at some of this guys audio-mulch set ups.
Now that VSTs are supported, I like using multiple loop or file players, with VSTs. Sort of like turntables.
I've finally figured out how to hook up the VSTi soft synths to my ancient Korg.
You can map the VSTs as well to external controlers, but so far as that goes I have only gotten the pitch bend or joystick to control any parameters.
But young people who are into this buy dedicated midi controllers with knobs of all sorts on a small box. I guess. I'm not part of your scene.
I just dabble.
I just learned that joystick trick today, but I want to know how to use keys on the keyboard of my ancient synth to control effect parameters.
