> and likely soon ZRythm
For now it seems the gratis version of ZRythm has "Save/load disabled" (!) and doesn't even include access to the PDF manual (!?); do you have information about their plans in the near future?
(That said, the paid versions of ZRythm are really inexpensive.)
Hi I'm the Zrythm author. No plans to change the current price model because it's reasonable (based on user feedback) and seems to be working. Haven't seen any good arguments against the current model other than people wanting everything to be gratis, but I'm all ears if you have recommendations
Bespoke, an innovative, idiosyncractic modular music making environment, is also gratis and libre.
The LV2 plugin API has on the order of a thousand gratis and libre plugins that do almost anything you can imagine, and a bunch of stuff you probably cannot, and there are also many VST and AU plugins that are gratis (but frequently not libre).
