Okay, sorry for the delay first. The app still doesn't notify me that there was a reply. Secondly, Impact can have multiple stereo and mono outputs. Sixteen mono and sixteen stereo, giving a total of thirty-two outputs. There are two buttons next to the patch dropdown, one with an arrow point away from a bar which is your outputs. Click it and then tick the boxes you want to have as your ouputs. On the pads, click the double cirlce to bring up the output selections. Now you are assigning your ouputs as you desire. ##### Impact has the look and feel of and MPC controller and can be controlled by the Atom or Atom SQ controllers, or amy Akai or similar. (I used both Atoms b.t.w. and they are fun to use). But you can drop any drum samples as you see fit. I gave gigabytes of kits that can be built from any of my samples i have collected over the past decade. Plus the kits I have for Impact. Also Impact may sit on one instrument track but it can output to 32 audio tracks - due to the way Studio One handles tracks and channels. ####### Studio One controlling your drum module? Depends on your module. On a technical level, Studio One sends and receives standard midi data. Again it depends on how you are set up. Do you connect via usb or Midi 5 pin din? What kit are you using?
