Antimateria: I have a decent PC well in CPU-wise but I don't have any programs to do anything.
chevkoch: There are lots of resources for creating music. One starting point might be
this thread on the Reaper forums (and Reaper is a great, basically free-to-use digital audio workstation - no need to buy Ableton I guess) plus maybe
this list of tutorials, and - specific to Synthwave - the
outrun subreddit. There is so much out there, info and tools, it's just a matter of starting, I suppose :)
I have midi-keyboard but I don't really use it.. I'm not that good with piano. I'l read those things tomorrow. Could be good thing to do.
I know that there are some free programs but I just never learned musical sheets or what not.. I did something in my feeling and with a hearing. Do I actually know stuff and make a sheet of it. No.
Edit: sheets are made for wiping arse! =)
