3J, Pipeline beat me to this one. I am not sure what part of world he lives in, but he is quick on these types of questions. grin

The Omni midi input in Kontakt can simplify a workflow. Keep in mind, a single instance of Kontakt on a single track can service multiple midi instruments across multiple Reaper tracks all at the same time. This minimizes CPU usage. In the early days I took advantage of this using templates which configured each midi channel to a specific Kontakt instrument. In this way you need to specify the individual midi channels (0, 1, 2 ...) for each midi track. But it does get to be complicated! So in more recent times I tend to simply put a different instance of Kontakt on multiple tracks, one for each instrument. With this no need to know or care what midi channel is being used, so Omni work great.

So if you don't want to use Omni and do want to use a single Kontakt you need to remember the BIAB midi channel map:
Bass - ch2
Piano - ch3
Drums - ch10
Guitar - ch6
Strings - ch7
Melody - ch4
Soloist - ch8


The other thing you need to be aware of is the octave of the midi data. Different Kontakt instruments utilize different areas of the keyboard for playing their instruments. BAIB tends to import its MIDI data at the low end (C1 - C2) and you need to transpose the notes up 1 or 2 octaves (C3 - C4). You can do this in Reaper with a click of the button.

Glad to see you are getting on with this stuff... grin
