User reviews

Most beautiful of programs

I scan images of art I love, and then “play” those interactively. It’s gorgeous.

Amazing app

Very very cool, thank you sir.

Camera issues

i want to use my camera on my mac, but it says that my camera is not vailable. Are there any ways to make it work / am I doing something wrong? But in general, Vosis is a remarkable sound design tool! Thank u

Future updates I am wishing for

I love this app, my current update wishes are the following:

Ability to scan the whole screen - I prepare and draw out images to be scanned. I feel restricted with the max size of the scanning cube. I wish this could be expanded.

I wish for chromatic and if possible customizable scales.

Option to save just the audio. I use another program to extract the audio off the saved video to place in my DAW.

AUv3 connectivity with tempo sync. This would be a game changer and a lot of people would get a hold of this app.

Midi out would be a nice to have. Even though audio to midi tend to never be perfect. It’s nice to have the raw track to use as a starter to arrange parts with other synths.

niice 👌

love this app its supercool i can spend hrs creating drones w this thing, seing what my face sounds like etc. it has a low growl that i really like. for me iphone xr 16.5.1 no issues w crashing. only slight downside is i can’t record and export to audioshare i have to go thru LumaFX and export the audio only, no biggie but kind of a pain. ps. i cant get it to work in audiobus or aum i load it up but when i add effects apps to it the vosis stops making sound, even tho its recording. maybe im doing something wrong i dunno. anyway, drone on
