I would really love it if the neighbor machine became more like a Bus machine where you would have a number of options on the playback page for how it functions. it would be nice to be able to switch it from an "insert" type processor or a "send" type processor.
+ 1 for amp settings on master track and +1 for neighbor machine improvements. I already shot Elektron a suggestion outlining an alternative use for the neighbor track as a bus track that could receive audio from up to six other tracks. As it stands I only use the neighbor machine temporarily until I bounce the audio to free up the track.
