A new open source modular additive polyphonic software synthesizer by Sean Luke.
"It's called Flow, and we've been working on it at George Mason University for a year or so. Download it at github.com/eclab/flow/. It's still got some wires hanging out here and there, and could use some polishing and improvement, but it's ready to go.
Flow is a fully modular polyphonic additive synthesizer. It supports up to 16 voices, up to 256 partials, and has about 50 modules right now. It also supports macro modules: you can save patches and load them as modules to be used in later patches (including parameterizing them). It comes with an extensive manual too. And it supports MPE.
Flow is useful as a music synthesizer and as a teaching and research tool. As you might suspect this is computationally expensive: it's a standalone, not a VST, and with typically about 30 threads running it'll keep your computer nice and warm. :-) Typically uses about 2.5 cores on my Macbook.
Flow is meant to be easy to extend with new modules of your own design: and indeed the back half of the manual is dedicated to software developer walk-throughs.
The software runs on MacOS, Linux, and Windows.
Flow Version 0 is in prerelease, meaning that changes we make are likely to not be backward compatible and could well break your patches (we'll try not to). But try it out, let me know what you think. Write some patches! Design some new modules! We'd love some feedback and contribution."
