Today I present my newest iOS/Mac creation: MIDI FX, an app to control all your MIDI devices and process MIDI notes to accomplish a great variety of effects such as creating harmonies, delays, etc… or filter notes to send to different synths or effect chains. It works with MIDI compatible external gear if you connect a MIDI interface but also internally with other apps that support virtual MIDI.
I plan on releasing MIDI FX soon, so if you’re a musician, especially using multiple synths to play live, keep an eye on this page!
