I have been entranced by Berlin School music for years. I love those evolving and interwoven arpeggios. Latching an arp is often my favorite way to noodle on a synth, and yes it’s because I can’t play to save my life.Last month I got tired of waiting for someone else to build my dream arp machine, so I built my own in the form of a web synth. It is purpose-built for sculpting and performing with melodies. I call it the AM-1 Arpeggio Machine.My next goal is to port the web engine into hardware format (using the Daisy Seed). But in the meantime, since the web app is perfectly usable, I figured why not make it free and open source. It can be used as a fun and interactive patch tool for the eventual hardware version.App: https://crux.garden/zacos/am-1 Source: https://github.com/zacos-techThanks, Will
