I don’t understand. Do you expect the Octatrack to read your mind and begin sampling when you think it should? Or do you want a sort of “begin sampling after x” kinda thing?
First things first, are you trying to sample external gear that is synced to the Octatrack? Or random recordings that won’t be in time with whatever you got going on?
For the former situation, you’ll want a track ready to record the inputs for a set length of time. So if your pattern is two bars long, you’ll want its recording length to be 32 and for the sake of your sanity you’ll probably want quantized rec to be PLEN (pattern length) or 32. Then all you do is press REC1 (if you want to record AB) and it will start recording in time and end recording in time. Make sure this track is a flex machine set to its rec buffer, and bam lay down a trig and now it’s playing back your recording.
I find this video really helpful.
The OT definitely requires a lot of front end brainpower to get it to do what you want. But you do it enough times and then it’ll become muscle memory. It really does require some serious thinking at first though, no two ways about it
It’s also the only instrument that does what it does so well and this is partly due to the fact that the sampling isn’t super easy. Once the recording is inside the machine there are so many things you can do with it all without stopping playback. You can slice it up and lay down some random trigs, then p lock any of those trigs to be different pitches, different FX settings, different rates…You can resample whatever that is if you want and do it all over again and never press the stop button.
That’s not easy to do–but it’s possible and just takes practice. Make no mistake–what that guy does in the above video is a lot of muscle memory. Going that fast takes time and effort. I still have to consciously think about those sorts of decisions he makes and still second guess myself sometimes.
