Hello, everyone! I released CS-16 last year in July (man, time flies!) but I never made a forum post. So, here we are!
CS-16 is a simple 16 track synthesizer. It has an up to 128 step sequencer (but this may change 
), a sampler, sample editor, and has many customization options.
Here's the introduction video, and a couple screenshots:
And once again, it's free and open source on GitHub. Have fun!
