I was recently contracted by Guitar Player Magazine to review the new IK Multimedia Stomp I/O (look for the review in GP in the next couple of months). It lets you send audio and MIDI to an iPad, so I took the opportunity to set up a quick rig employing three of my favorite apps: iDensity, Aum, and Borderlands
AmpliTube remains my favorite amp and effect modeling software. I even wrote a book about it. They have offered an iOS version for a while now, along with iRig, an elegant mobile guitar interface. This month sees the release of new versions of both: iRig HD and AmpliTube 3.0, featuring AmpliTube Studio.
