I had one for awhile and used it with the Octatrack. The Electribe Sampler is very capable and a great companion to the Octatrack, as long as you’re aware of its somewhat odd limitations. It’s taken a lot of heat, mostly because people expected it to be something it’s not. But approach it with no preconceptions and just learn what it can and can’t do, and it’ll be a great companion to the Octatrack.
I found it worked best when I had one pattern going on the Tribe, no matter what I did on the Octatrack. While Korg has adjusted the glitches that occur when you switch patterns on the Tribe, they’re not entirely gone and you will eventually run into situations where it’ll just annoy the hell out of you. I believe Korg’s intention was to build a rich and extensive live-oriented set within one dedicated pattern, and then switch to the next one as you switch songs in a deck. To use five-ten patterns to build a song, will frustrate you. But one pattern with sixteen tracks within the Tribe sampler, will get you very, very far.
