Is Reaper messing with me? (Routing problem)

[Aron-san]

Yoyoyo, what's up. I'm trying to set up some drum samples with ReaSamplOmatic. I started with jamester's template but I changed it around a bit and added samples and new tracks etc. Anyway, there seems to be something weird happening after the 9th track. The routing is fine for the samples carried in Tracks 3 to 9, but from Track 10, the routing gets messed up.

The ReaDrums I/O settings for Track 10 and the remaining tracks are just following the settings used for Track 3-9. So, the settings are: Track 10 (Audio 17/18), Track 11 (Audio 19/20), Track 12 (Audio 21/22) and Track 13 (Audio 23/24). However, when playing the samples on the MIDI Keyboard that are supposed to be sent to Track 10-13, they are only sent to the ReaDrums Track (Track 2). Haha what the hell is going? Have I missed something?

Thanks for the help!
