# Vital
Vital is a spectral warping wavetable synthesizer. This is the source.
This repository is updated on a delay after binary releases.
## Code Licensing
If you are making a proprietary or closed source app and would like to use Vital's source code, contact licensing@vital.audio for non GPLv3 licensing options.
## Installing
Create an account and download Vital at [vital.audio](https://vital.audio)
## Issues
Report bugs (e.g.non-code and non-compiling issues) to https://forum.vital.audio
Feel free to report issues on building/compiling here but note that I'm not prioritizing them.
## Pull requests
I will not take any pull requests.
## What can you do with the source
The source code is licensed under the GPLv3. If you download the source or create builds you must comply with that license.
### Things you can't do with this source
- Do not create an app and distribute it on the iOS app store. The app store is not comptabile with GPLv3 and you'll only get an exception for this if you're paying for a GPLv3 exception for Vital's source (see Code Licensing above).
- Do not use the name "Vital", "Vital Audio", "Tytel" or "Matt Tytel" for marketing or to name any distribution of binaries built with this source. This source code does not give you rights to infringe on trademarks.
- Do not connect to any web service at https://vital.audio, https://account.vital.audio or https://store.vital.audio from your own builds. This is against the terms of using those sites.
- Do not distribute the presets that come with the free version of Vital. They're under a separate license that does not allow redistribution.

Important Note!!
================
The purpose of this folder is to contain files that are auto-generated by the Projucer,
and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
the Projucer saves your project.
Therefore, it's a bad idea to make any manual changes to the files in here, or to
put any of your own files in here if you don't want to lose them. (Of course you may choose
to add the folder's contents to your version-control system so that you can re-merge your own
modifications after the Projucer has saved its changes).
