When I design my drum kit, I use 12 tracks, say 6 instruments and 6 notemapper plugins. I use midi keyboard when sound design, but I like to play drums on my edrum kit. I don't want to change input on 12 channels, that's why I never use my edrum kit. One solution would be to select MIDI input on the folder track in order to change input settings on all 12 drum tracks.
