Simple midi recorder for iphone?

Bought iRig midi - the original one - just to be able to record improvisation on my piano onto my phone. Recorded no problem, but when trying to send the midi-file as email, the midi recorder-app froze. Talked to the iRig-people and they said the software is out of date, and they may not update it.

Ergo - anyone know of a simple midi recorder app for iphone, where I can just hit record and not think about it, and when I´m finished recording, I can easily send as email etc.?

Cheers!
