Rusty Pipes is a digital organ instrument compatible with GrandOrgue sample sets. It features both graphical and text-based user interface, can be controlled via MIDI and play back MIDI files. Rusty Pipes can stream samples from disk instead of load them into RAM, though a RAM precache mode similar to GrandOrgue and Hauptwerk is available too.
A web-synthesizer that generates sound from the binary code of any files. It can synthesize sound directly in the browser, or be a generator of MIDI messages to external devices or DAWs, turning any file into a score. All the application code is written in Javascript and along with everything you need is packed into a single .html file of about 750kb. The synthesizer doesn’t need internet, it can be downloaded and run locally on any device with a browser.
The application reads the file sequentially, and due to the high speed of reading and random deviation of reading duration, we can get quite unpredictable generation of timbre nuances, and at certain settings we can switch to granular synthesis.
