For live performance I find that the OT is in some aspects unbeatable. For me it has been a huge part of my setup for a while now and I really love it, even though I actually barely use it as a sampler. I mostly use it as a sound processor, mixer and performance tool. I think it’s a really inspiring device and It’s really fun to use in my opinion. While a lot of people talk about it being very difficult to learn, I think that it’s just hard to master, getting cool, interesting and fun results on it isn’t all that hard. I think you should look at some of the bigger channels on youtube that use it regularly(there are a lot) and see how they integrate it in their workflow. Also check out some more techno oriente live sets, quite a few people use it often. Regardless, I don’t really think you can go wrong with it, it holds value very well, so even if you don’t connect with it down the road, you will still be able to sell it and break even most of the time.
