For the last year or so I’ve been cranking out tunes on the (limiting but fun) Super Nintendo.
My demoscene buddy Ferris (coder / lead-dev) and myself (tester / breaker / pleb-dev) are working on a SNES music tool that outputs cartridge ready binary ROM images. The end game (ideally) is that it runs a live mode for you to perform pre-written tracks with. But y’ know… these things are easy to announce – making stable and working tools takes time. We’ve been plucking away at it for a year, and it’ll probably take another to get it super stable.
The music tool runs on a PC. (and mac / linux eventually) – The ROM this tool generates plays on a real SNES.
So far it’s working, but there are still milestones to reach before we can release a public beta. The project should get finished one of these days… start of 2016 maybe? So hang in there and start collecting short samples 
You can show Ferris some love by supporting his music
– Full ADSR control with INS import from SPC (working)
– Realistic emulated preview: WYHIWYG (working)
– Visual DSP Programmer for custom efx (in dev)
– Standard interface with copy + paste + transpose features (in dev)
– ONE CLICK “compile ROM” from file menu for fast play (works, with a few issues)
– Pattern optimization / compression in play routine (working)
– Live mode interface with on-the-fly sequencer / part muting (interface built)
– Advanced ROM compiler for making live mode (partially working)

Here are some tests / SNES demos!
