an interactive grid-based music sequencer for creating evolving, generative compositions
More details on my website: https://aronrocco.at/gemupg.html
gemupg is a visual music creation tool that lets you build generative compositions using a flexible grid system. place generator blocks to create sounds, sequencer blocks to control patterns, and areas to group and sequence your musical elements. perfect for experimental music, ambient soundscapes, and algorithmic composition.
requirements:
- CMake >= 3.25
- gcc >= 13 (or compatible c++23 compiler)
- sdl3 build dependencies (see sdl3 docs)

- create areas - define regions on the grid where your sequences will play
- add generators - place generator blocks with different waveforms
- add sequencers - place sequencer blocks of four types around the sides of the areaas, control timing and pitch
- fine-tune - adjust parameters of blocks and areas in real-time
