Nudges is a monthly musical effort started by Scott Harper from his Knobs Patreon page. Every month there’s a new challenge to compose a musical piece with certain rules/limits/boundaries which promotes and enhances creativity and community.
All financial support goes to charity
The first one was called Synthesized loops and, as the name implies, it was using a looper to made a musical piece that sounded fluid and natural
The second one´s called Using it Wrong. It was about using an instrument in an unconventional way to create a short or long audio track.
There´s lots of good material there and the discord channel (Accesed as a patreon subscriber) is very friendly and chatty.
