I am trying to layer 3 sound modules and giga and can't do this as i'm playing such that all devices are playing layer form. I have connected my controller to a midisport usb 4x4, and outputs from the midisport are going to teh various external modules. My sequencer will not let me PLAY in real time muliple tracks simultaneously, except during recording play back. So when I want to just play my keyboard and layer sounds from other devices, not using sequencer software, I have to disconnect all my cables and connect my ext modules to my controller directly, then I can layer sounds again. I guess Sonar does this through what they call "echoing" tracks (play in one track, and have that input drive other tracks at the same time). Does FruityLoops?
