The OT and Ableton are quite different eco-systems. There are some similarities, sure, but also many differences. Both compare badly.
For me the workflow on the OT is completely different compared to Ableton. The operation of all Elektron instruments using their sonic options together with the built-in sequencers is, after some training, much more like playing an instrument live. But if I’m using a DAW, I tend to construct clips, arrangements, tracks piece by piece. This said, I use both, but enjoy the different approaches to generate ideas and entire tracks … with different outcomes, of course.
With the integrated Ableton sound and midi tools and some plug-ins, it should be possible, to get very close to results, which could be generated by an OT sonically and track-wise. But if we watch how great artists like Project Dataline (aka Jenk) are performing on those Elektron machines in a live situation, I would say, not really possible with Ableton even combined with Push. Why …
The accessability of almost all parameters of a complex sound engine via p-locks is unrivaled, AFAIK. Just think about more then 200 parameters of the OT. Just move one of the encoders to change something, hold down one of the trig-keys in step-record mode and make a change. Without doing more, it’s accepted and stored directly to the track. Imagine doing this with a similar complex sound-plug-in or an instrument/effect rack in Ableton using so many different CC-parameters in a live situation. I would say … a nightmare
I would say:
- If your goal is something like creative creation of clips and launching or working in a MPC like style, Ableton with Push could be the solution.
- If you would like to play a flexible instrument with many sound-mangling options at your fingertips without the need of much thinking and planning ahead, go for the OT.
