I’m on my 2nd OT and I don’t think I’ll ever sell it, but it definitely isn’t all it’s cracked up to be. The whole “live with the limitations” thing is harder and harder to do as technology advances. Unfortunately, there really isn’t anything else out there that is quite like the OT in terms of the combination of features and physical form, so it’s hard to find something to replace it. Drambo, on the iPad, COULD be a pretty good replacement if you had a dedicated controller and template setup, but that then requires you to have multiple pieces of gear (soundcard, MIDI controller, etc.).
Some of the “limitations” like monophonic sampling, individual outs/USB audio, track muting also muting tail FX, FX quality and no reverb/delay on the same track, and FLEX RAM limit make it hard to utilize in certain ways. I used to think that the OT was the “build an entire song in a box” type machine, but once I stopped using it like that and started using it more like an instrument, it became a bit more inspirational. I still struggle with it sometimes, though. I tend to use it more to make parts for songs as opposed to making whole tracks on it (unless I’m just jamming out).
I tend to suggest to people to buy a MKI used if they’re not sure if they’ll dig it. It definitely isn’t for everyone, but if you can find a way to play it that you enjoy, it’s definitely a cool machine.
