- 4Hacker News·9/25/2026open_sourceCZP-1 Adds Casio CZ-101 Patch Sharing
The CZP-1 web-based synthesizer can now load patch banks from JSON files and share sounds through encoded URLs. The post describes importing Casio CZ-101 patch data and recreating it closely in the browser-based instrument, with the main difference coming from missing post-processing effects. It also notes that bank data persists locally in the browser and can be managed across tabs.
- 6Hugging Face Blog·9/23/2026framework_updateHow NVIDIA Warp and MJWarp Speed Up Robotics Simulation
The article explains how MuJoCo Warp (MJWarp), built on NVIDIA Warp, moves compatible MuJoCo robotics simulations from CPU execution to large-batch GPU execution. It highlights a workflow that scales an SO-101 arm simulation to up to 2,048 parallel environments and describes validation and integration steps, without training a policy.
- 4Hacker News·9/5/2026open_sourceHN user explores AI-generated PianoDisc MIDI encoder and decoder
A Hacker News post describes experimenting with AI assistants to analyze and reproduce PianoDisc Prodigy piano-file formats, including encoding MIDI into MP3 right-channel data. The user reports that the system can also generate decoy notes and asks whether releasing the encoder or decoder would be allowed.
- 6Hacker News·8/20/2026researchOn-device piano autocomplete model runs in real time on iPhone
A developer trained a 125M-parameter transformer to autocomplete piano performances in real time on-device, reportedly reaching about 108 notes per second on an iPhone 15. The work highlights the importance of MIDI representation, aggressive data cleaning, and DPO post-training for improving musical continuation quality.
- 3Hacker News·7/19/2026product_launchLessons from Selling 2,500 MIDI Recorders
The author reflects on launching Jamcorder, a piano recording device that has sold 2,500 units and become a viable business. The main takeaway is that hardware was easier than expected, while software development remained the hardest part, and the post includes practical advice for shipping hardware at medium scale.
