This app has been under constant development since early 2016, continually growing and improving. Despite being in Early Access, the app is polished, stable, and packed full of features. Here’s a look at the basics of making music with EXA in VR:
RINGERS & THEIR SOUNDS
EXA’s musical shapes are called. They make sound when you hit or interact with them using one of the various(like a mallet, violin bow, or proximity tool). The ringers in EXA react to the velocity and angle that you play them, and they provide an extremely responsive, zero-latency playing experience.
You can change the sound that a ringer produces (like a drum, piano, guitar, synth, etc.) by choosing a different(SF2) or(WAV, AIFF, OGG) as its audio source. EXA ships with 1,000+ built-in sounds, and encourages you to import your own! You can change a ringer’s pitch by setting it to a specific note, shifting it up or down, or by applying a particular scale/interval across several selected ringers.
CREATING INSTRUMENTS
Ringers are the main building-block for creating your own. There are four available ringer shapes, and you can move and resize them however you want. Sketch new ringers out of thin air using the, and use theandfeatures to assist your instrument-creation process.
EXA’s virtual space gives you incredible flexibility for designing entirely new and “impossible” musical instruments. You’re free to break away from traditional instrument structures, and instead create instruments that are perfectly suited to the way you want to move, the notes you want to play, and the musical performance you want to compose.
