Is having an analog drum engine important to you? Do you own any other drum synths?
If having the analog synthesis engine Of the RYTM isn’t a must for you, I’d second the voice that suggested a Digitakt.
Ease-of-use is phenomenal, sound quality is among the best, it’s got plenty functionality to play with, it samples in mono with two line inputs available, it’s FAST & IMMEDIATE to use and the form factor is compact. In a nutshell, it’s a flexible, great sounding sampler and cheaper than the RYTM.
To me, the Digitakt and the RYTM are first cousins, with the RYTM (Mk2 mind you) covering many of the features of the Digitakt PLUS extras such as the synthesis engine, song mode etc.
The OT is its own creature. Whereas the other Elektron devices sort of come with a clear respective purpose in a setup, the OT is so flexible, it takes your decision making to choose how and for what you want to use it. So this is the setting up time needed people mentioned here (eg you have eight audio tracks, but what role should each track occupy? Should one play back longer samples as backing track? Or should it function as a live looper? Or should it record samples on the fly so that you can mangle them in real time? Or should you “surrender“ one track as “Neighbour” track to increase the FX available to another track? Or should one track direct monitor your inputs so that you can mangle & fx your live input? etc etc).
Once you find a good workflow for yourself though, that can be it with the setup of the OT and it becomes as immediate as any other Elektron big box.
There’s nothing like the OT out there for sample mangling in the hardware world. For me I’d always recommend it if I know a sampler/sample mangler for all sorts of content (drum, melodic, harmonic, sfx) is needed AND the person is ready and willing to embrace the learning curve.
If you are looking for an analog drum machine with sampling capabilities, the RYTM is it.
If you don’t need analog drum synthesis and are instead looking for a one-shot sampler that makes a GREAT sample-based drum machine and is fast and easy to use, I’d recommend the Digitakt.
