Only useful guitar MIDI app in the AppStore – Jam Synth Review

This is the only one worth getting. Maybe it works better because it uses its own sounds, but I deleted the others. Suggested setup for maximum usage-iRig into your device and Fiio adapter(used to go straight from D/A converter-bypasses headphone amp which your guitar is plugged into anyways, so that's the only way to do this) into a stereo female to male cable, and then into a splitter to go into 2 line inputs of your interface(panned left and right to keep it in stereo). The Apple converters are very high quality, so the sound is outstanding and very professional. You'll find the adapter works with all your apps, the sound quality is stunning even considering you're using a phone or whatever.
