&pajama, my WRJ project, aspires to be a "music sketchpad" - not a professional-level DAW, but a simple tool to let you play around with and capture musical ideas with as little friction as possible. Yesterday I took my basic draw-rectangles-on-the-screen base layer (odin+SDL3) and added audio support. Today I hooked up portmidi and created bindings for the tinysoundfont single-header library, and created a basic virtual piano that supports mouse, computer keyboard, and midi keyboard input. I'm pretty pleased with my progress, that should be the bulk of the library wrangling (at least for jam purposes) out of the way, so I can focus on wheel reinvention.
