Hey all, sorry for being away, I'm waiting with uploading the wad to idgames till Avactor 2 will come out.
Avactor 2 will be released with extra map for Avactor 1 which this map is connecting between the two wads.
Thank you for your patience !
You can export the Midi files using Slade3 and just convert it to mp3 online for free. I assume it will change the quality of the soundtrack so you can also use FL-STUDIO like I'm using to keep the original quality and still turn it to a mp3 file.
If you dont have FL-STUDIO You can find the demo version on their site for free, you can't save projects but exporting Midi files you can freely.
As long as credits will be given you can use the soundtrack for everything you want.
If you have troubles converting the midis contact me on private and I'll help you with that.
