Vortex Sound Research

Hi all,

I have to travel next month and looking for a small keyboard with onboard sounds that runs on batteries or has an internal battery that can be charged.

So far the only thing that I've found is the Akai MPK mini MK III. It has onboard GM sounds which I know won't be great but I haven't seen anything else this small with sounds.

I don't have a laptop or tablet or even a very good phone so midi keyboard to a device like that won't work for me.

FWIW I have a Yamaha Reface CP and love it but it's a little too big for this trip.

Would appreciate any other suggestions! Thank you!
