When I render to a wav file I also get a song_render_drums.wav, a song_render_bass.wav, a song_render_piano.wav. I get these besides the regular song_render.wav that I need. Is there anyway to not save each of these other files? The main issue is that BIAB demands to put the rendered files in the same directory as the SGU file, which is getting really clogged up with these non essential files.
