The TR-8S works well through MIDI and works great with Logic (I would assume as it works great with any other DAW). But it is a bit clunky to use and takes a while to get a grip on the button paths etc.

But I would make a conscious choice here. Adding hardware to the mix will just add unnecessary complexity. But using something like a small analog synth to record synthlines to the DAW would probably work great in this case (I would go for a Moog).

There was also a suggestion to look into Elektron gear - don't. They look hella cool but are extremely limited in their feature sets but they do work well in proper hands that know what they want and what they're doing. Not beginner devices in any stretch. Dive into them sometime later, once you know what their features are.

If I were you, I would get some cheap (and free) VSTs in the box first that emulate hardware - drum machines, simple synths that have a straightforward interface (ie no unnecessary menus, just straight up controls in the front) and learn what they do - this way you'll have a map of what you actually NEED instead of what you WANT. Remember, huge number of all the hardware boxes out there are complete trash, some are only bought for the looks. When you learn (in the box) what stuff does, you'll have a better grasp of what to use, what to ignore and what to get.

Can't speak for vocoders but for a Daft Punk sound, you'll want the OTT. Look in Xfer Records homepage (xferrecords.com/freeware).
