The OT is not meant to be a portable Daw replacement. It’s an idiosyncratic instrument with some very specific design choices. Most notably, the ability to live record and manipulate audio on multiple channels. Almost all samplers have a standalone function to record, assign a sample and then playback. Where the OT differs is it’s ability to simultaneously mess with recorded audio AS IT’S RECORDING.
For example you could set up conditional trigs to create a recording chain, having a random chance of recording a recording from multiple channels. As another example, you can record a track playing back, assign it to another channel, randomly slice audio live and have playback trigs with random LFO slice. Live record spamming a bunch of tweaks to the sequence, and set up crossfader to go between regular loop and the jumbled one. You could then record your crossfader tweaks between the jumbled track and regular on the master channel, loop as it’s still playing, switch to the looped audio run a new pattern behind that and crossfade into the new sequence with Beatmatch. That’s not really the kind of think an Akai or Maschine is set up to do.
Also, while I do agree that the reverb and effects don’t sound great, they aren’t really there to be studio grade effects. They are there to do quirky live sequencer and scene manipulations. The FX quality of which I promise you nobody cares about when you are performing. If I really need good reverbs etc I just record in or sample from something that has good reverb instead of adding in with the OT.
