Good news for all VIC music composers! Pekka Väänänen aka cce has published a python utility that converts standard 4ch MODs to VIC-20 format. So, if you've always dreaded VICtracker and VDI, this is for you.
The utility requires Python 3.3 or higher to run. It also requires the win2c64 assembler, which is included in the download package.
Download mod2vic for Windows here, and check out the source and documentation here.
There's also a fork by Linde, which uses Kickassembler instead of win2c64, making mod2vic platform independant.
