Zytrax
ZyTrax is an easy to use music sequencer with an interface heavily inspired by 90's "tracker" software (most specifically Impulse Tracker).
While contemporary software that uses this approach exists, it usually has a high entry barrier because it maintains compatibility with old formats.
In contrast to this, ZyTrax starts afresh with an user friendly approach (no hex numbers, pure plugin-based architecture, inlined automation envelopes, smart automations, zoomable patterns and a simple pattern/orderlist layout).
Usage
Currently, ZyTrax runs only on Windows and Linux/X11. It supports VST2 plugins via Vestige. It should compile on MacOS but no plugin code exists (If anyone wants to contribute LV2 support, that would be awesome! I just don't have the time).
