Hi guys,
I just received my new AK and super excited. I own an MD and OT and I followed the setup as described in p68 of the manual (to use all 3 together).
I plug in headphones into the AK with Left In panned hard left and Right In panned hard right. The volumes are at 100 on both. Only sound coming from the Right In.
I switched cables and even used the same cables from the MD into the OT to test them and I got sound from both channels.
Is there setting I am missing on the AK? Have installed 1.12B from the elektron website. Really bummed 
Setup is as follows:
OT midi Out into AK midi In.
AK midi Thru into MD midi In.
MD Main Outs into AK Inputs.
AK Outs into OT C/D.
Can hear MD only on Right Input Channel and hence headphone can only hear from my right ear, (unless I pan channel to center). Moving the panning on Left Input Channel has no effect.
I really really REALLY hope this is not a hardware faulty input from the factory!
Any help appreciated!
Niko

Pressing Clear Kit solved the problem. Looks like there must have been some weird funky settings on the default pattern when switching on for the first time. THANK YOU CENK !!!
