1) If an .ins with drums and sfx banks exists, I haven't seen it, and am too lazy to program it myself. If you find one or do it yourself, please send it to me.
2) Push the "Performance" button before recording or playback (to take the N1 out of Multi) and you'll get your f/x. Unfortunately, there doesn't seem to be a sysex message you can send to the N1 to set the native f/x.
