Hey HN, I’m an ex-Google engineer trying to get back into music production. I needed a way to sequence my hardware synths using AI contexts without constantly switching windows, so I built this. It runs entirely in the browser using WebMIDI. No login required. It connects to your local MIDI devices (if you're on Chrome/Edge) and lets you generate patterns. Tech stack: [React / WebMIDI API / etc]. Link: www.simplychris.ai/droplets Code is a bit messy, but it works. Feedback welcome.

Originally started as a project to restore patterns from now defunct website 808.pixll.de just for myself, but eventually i decided to share it with others. I've seen this website mentioned a couple of times on HN:) Currently it only supports Roland TR-808, but there will be more.

In 2020, Magenta released DDSP [1], a machine learning algorithm / python library which made it possible to generate good sounding instrument synthesizers from about 6-10 minutes of data. While working with DDSP for a project, we realised how it was actually quite hard to find 6-10 minute of clean recordings of monophonic instruments. In this project, we have combined the DDSP architecture with a domain adaptation technique from speech synthesis [2]. This domain adaptation technique works by pre-training our model on many different recordings from the Solos dataset [3] first and then…

Hi HN! We're a small team in Lille (France) who make synthesizers and MIDI controllers. We've just released a virtual plugin version of our hardware synth Anyma Phi, which offers a semi-modular environment with a focus on physical models, although there are several other kinds of synthesis. Here's a video: https://www.youtube.com/watch?v=6efDQ9GmRpg We're not pivoting to VSTs, it's just that it was a practical way of investigating several issues and helping us with the ongoing development of our upcoming Kickstarter-backed synth (Anyma Omega) and MPE controller (Loom), and a…
