The A2M tool is designed for real-time Audio to MIDI conversion.
Convert your audio source directly to MIDI.
Connect your guitar to the line input or a different analogue instrument via a microphone, play it, and hear any instrument selected from a range of samplers and synthesizers.
A2M itself does not have any built-in samples, but it allows you to use thousands of excellent third-party virtual instruments.
Any instrument which receives MIDI (both physical instruments as well as virtual plug-ins) will work with the application.
