Yes, it was a midi issue and here i was thinking choosing omni meant choosing ALL the midi channels.
Reason i was really stumped was because i use other plugins and they just play without me changing midi channels etc. Now i know i'll have to change the channel at least for the triton.
I guess this is the price i have to pay for migrating from logic pro x which has minimal midi application.
In any case, i'd like to thank you for your time. I greatly appreciate it.
