Deluge MIDI Manager

I created a YouTube search-optimised demo video showing how to use the app and started selling the app through my website.

I shared it in the Deluge forum, the subreddit and the fan Discord server, tweeted, and that was about the extent of my marketing.

I went live and streamed the initial development of the app.

There were some technical people in the audience which helped me get everything on the right track.

This was probably the longest development session, after which I privately polished things up and added a licensing system.
