i just bought a radium,how do i choose which jey each sample goes to, like so i ca play piano on the hole thing or put many different drum noises on different keys?
Add whatever vsti you are using. Click on the left hand corner of the vsti that you added. (The window that has the vsti User Interface after you click on a channel in the step sequencer)
Then go to "link to controller", pick a function, move the fader/knob on your midi controller and you're set.
