Introduction
MIDI files don't actually contain any audio, they are simply instructions describing how audio is to be played. In order to have the MIDI instructions translated into sounds, you need to use them to control a virtual instrument. Generally speaking, virtual instruments fall into two categories: those that generate their own sounds and those which use audio samples.
Audio Evolution Mobile Studio gives you both types of virtual instrument. Evolution One is a sophisticated virtual analog synthesizer based on Synth One by Audiokit and Audio Evolution Mobile's built in sampler allows you to use Soundfont and SFZ sample-based instruments and create your own SFZ instruments.On iOS, you can also use any instrument Audio Unit (AU) or IAA that is installed on your device. Additionally, Audio Evolution Mobile offers the stunning Flowtones synthesizer by Toneboosters as an in-app purchase .
In order to use a virtual instrument you first need to add a MIDI Instrument or Drum Pattern track to your project. For information on how to do this, and how to select your virtual instrument, please see here.
