I'm uctumi, an active music composer for C64 and PC platforms.
I enjoy the sound of the SID chip and the possibilities it has within its limitations, you can still give it your personal touch!
Though my fist platform has been the PC in which I composed several Fasttracker 2 modules.
Currently I use openMPT for tracked PC modules. Also for creating streaming music I use renoise.
For C64 music I like to compose in CheeseCutter, SidWizard and Goattracker.
You can find most if not all my PC modules at modarchive
For my tracked SID music executables go to my CSDB profile
If you're too lazy for all of the above, I have a soundcloud page and a youtube channel.

I specially enjoy composing melodic tunes, though I love well-done rhythmic stuff as well.
