  Here's a DIY hacked Cynthcart, which is connected to the NES, making this a synthesizer with the power of both the C64 SID and the NES audio chip.

This is for the SID fans out there: a freeware SID-emulating VSTi for Windows.

This piece of software allows you to make songs by emulating a Commodore 64 sound chip. Great stuff, and it's free to download!
