smoother keygroup looping

I made a 17 keygroup organ with some samples and I am trying to figure out how to best make the looping of the key when i hold it. I have loop lock on as well as zero snap. I have tried all 3 forward, alternating and reverse, with alternating sounding best. However, I still hear the pops and clicks and its not a smooth continous sound. I tried zooming in to the waveform and trying my best to match up the start and end point loop, but its just not sounding right. Am I missing a crossfade feature or something on the akai force to make this smoother?

If you haven't tried yet - chop the samples so the start an end is exactly on the zero crossing of the Waveform.
That should usually do the trick

Thanks, i forgot to mention also that i autosampled this in stereo. This would mean that the waveforms are a bit different between the two. Is it best practice to do all autosampled instruments in mono?

Mono certainly makes things easier, but you can also use a very tight fade in/out on the ends of your sample to reduce clicks.
