If you have an old gameboy lying around (you can find em cheap too!) you could look into
nanoloop. It has a strange interface that forces you to think outside the box, the synths are also really rough, and can sound kinda glitchy. There's a ton of weird synths you can get on a gameboy as well
here's a list!If you wanna throw down some serious scratch get a tenori on

very cool interface, very organic, but very expensive (close to a grand I think)
Otherwise, I'd suggest step sequencers for beginning beat making. It's more fluid, it makes more sense usually. You could always pick up some old drum machine and try to bend it. Usually when I try to get more ambient I use a lot of echoes on more standard drum patterns, also LFO based effects work wonders if you time the sweep just so to the pattern playing. Mostly the problems I run into when programming and sequencing is that I want the live performance, and when I try and record the live performance, I want the precision of the programming.
And from my perspective I'd steer clear of the Monome thing, because it's so software based, you have to use the computer just as much, but I'm a very hardware oriented guy, it's always made more sense to me.
