Small external effect devices (mainly for Rolands AIRA MX-1)?

[Tomac Barin]

I received Rolands new AIRA MX-1 the other day, and been having a lot of fun with it ever since.
However, I want an external effect device for it. I have an old Zoom Studio 1204, which is kind of cool (gotta love that vocoder), but it is too big and clumsy for my setup. I was thinking of something more compact, yet still versatile.

I really like Korg mini Kaoss Pad 2S (and will probably go for it), but I thought I'd ask you guys if you have any more tips on similar devices. (They don't have to be that pocket small, but preferably not bigger than an, let's say, Roland TB-3 either.)

Bonne journée !
