John,
Great information. I am using BIAB with the conductor. No Tranzporter hardware. I only use the Laptop "hotkeys." Actually, I use conductor shortcut keys so that I do not need to bring up the conductor window. Songs are BIAB songs, not recorded MP3 songs. This way I can play with midi songs and loop back when ever and where ever I need. I do this often as a real band would do.
