noob need help

See this post for free tools that allow you to transfer files to audio tape using any tape deck. (WAV-PRG is the one you need just for transferring files)  In my experience a lot of c64 editors are expecting a disk drive for storage (the good ones are usually written by demosceners and sceners always have disks) but older '80s tools like Ubik's Musik, Electrosound etc. had tape options.

Yeah afaik it's a good device, lot of people in the scene have them.  Though if you want to use Mssiah doesn't that come in a custom cartridge with midi ports on it?

If you're looking for software the big scene resource is CSDB.  I linked a few things in that tape link earlier, but some other trackers are SDI, JCH Music editor, Odin Tracker, Sound Monitor, Rock Monitor....  there are literally 100s of c64 music editors out there.

If you don't find a flashdrive a cheaper way is to buy an old 1541 drive, stick the files you want on tape (using WAV-PRG) and then transfer them onto real disks on hardware.  There are various c64 tools to do that. Sure it's laborious but you only need do it once.  When the tools are over you can forget tapes and stick with the disk drive.  I've used that method for years.

you could also build a serial/parallel transfer cable:

and use it to transfer files between a real 1541 (or other C= ) drives and your PC and vice versa with the following tool:

do note if you have a parallel printer (you prob dont) you will need to 'unlock' the printer port before you print once you have installed this tool...

hope that helps \o_
