Of course you can. But if you can only make music with a grid - in fact if you can only imagine music with a grid - that's not necessarily ideal.

Ableton is actually textbook modernism - mechanised regular repeating patterns, both in the GUI and in the kind of music it encourages.

Which is fine as far as it goes - as long as you realise there are other possibilities, and that that kind of modernism is more than a century old now.
