WAV2Evolver Waveform Generator for the DSI Evolver Line

I was chatting with Brian Comnes about waveform editors for the DSI Evolver. There are the SoundTower and Vyzor editors that give you access to the full parameters of the Evolvers, but if you just want to create and upload waveforms, Brian let me know about WAV2Evolver, a free online editor that does just that. Thank you Brian!

See if you can make out my lame attempt at a waveform to the left. Note you can have only one point along the horizontal plane. I actually never thought about that before.

Update: the output is a .wav file so this could be useful for other synths and applications.

Some details from

"WAV2Evolver is an online waveform conversion application for users of the Dave Smith Instruments Evolver family of synthesizers.

It allows you to upload WAV files containing single-cycle waveforms, and then download them as system exclusive files that the Evolver can understand. You may also download waveforms as RAW PCM files or new WAV files. The RAW and WAV files downloaded from this application use Evolver-friendly 128-sample, 16-bit PCM.

WAV2Evolver is also a waveform sharing application. You may view and download waveforms that others have generated, and you may share waveforms that you have generated. I encourage you to share your waveforms, although this is completely optional.

WAV2Evolver is an HTML5 application. If it's not working for you, please try using an up-to-date web browser. WAV2Evolver was written with the following technologies: jQuery and Bootstrap were used to construct the interface; PHP was used for the web services that transfer data to and from the application; the waveform conversion tools are written in C. The icons are by Glyphicons.

All of the code for this project is open-source, and can be found on GitHub.

Special thanks to forum user Razmo for his invaluable help in proving out the conversion code, long before I had an Evolver of my own."
