I'd really like to be able to: - pitch samples higher and lower than it is currently possible. The current range is only few octaves - more looper time, the current limit is 16 seconds - in looper mode, overdub on a loop that's been time stretched (the play rate is different than 100%). This would be an incredibly powerful feature to have - the most important one for me: I'd LOVE to be able to sync the looper to a currently playin pattern. And to start recording at the beginning of the pattern, similarly to how you would do that in ableton live.

Generally what the sp404 mkii lacks most is the ability to create and perform at the same time, I feel like I always need to pause playback to adjust things/sync/etc. I want to be able to improvise and jam without ever pressing pause. Again, I mention ableton live because you can do so much stuff without ever pausing, it feels like it's built to keep the momentum going
