Crash-Headroom: I thought I'd come on here to clear this up a little as the O.P. hasn't got all his facts strait XD
They are not for sale, it's just the problem is i am on a free bandcamp account, that only gives 200 free downloads a month, after that it reverts by itself to payment. I made sure to put it at the minimum 50p when this happens, and I also make sure to leave a message telling people when I have free credits left, and when I dont. If people after that point donate me a 50p to help me remaster old soundtracks, I thank them, but lets just make this clear. Im not purposfully selling anything and warn people when those free downloads have run out. I hope that clears this up.
There are actually a few people who have done what I have done on bandcamp with these unreal soundtracks, its just they didn't take the time to mix them.
Some lovely posts here truely without getting in contact with me to get the full facts, people are very judgemental without the single bit of research :/.
It doesn't matter if you are selling them or not. If you do not have distribution rights, you are committing copyright infringement.
Further, you haven't remixed or remastered anything. For the MIDI-based soundtracks you are simply recording them with the use of a different sound bank, which you also do not appear to have commercial use licences for. For example you are using the Arachno soundfont for the System Shock soundtrack and the licencing information for the Arachno soundfont states:
"You're free to use Arachno SoundFont in any of your projects. But, please be aware that this bank is primarily distributed for private, non-commercial purposes only, as it uses portions from other authors. If you want to use it for commercial purposes, please obtain a written consent from the original authors credited in the Preset list and Copyright information and credits sections."
For the module based formats (which you erroneously refer to as "glorified MIDI files") such as the Unreal soundtrack, I hear no difference from the originals. All you appear to have done is played them back with some kind of resampler and/or filter, which is a feature that many audio players have built-in. You haven't even replaced the samples in the UMX files and yet you're trying to tack a credit for yourself on to them for simply recording them into PCM audio.
That is irrelevant however, as you don't have the rights to these pieces anyways. In addition you are trying to profit from them, which is going to give the rights holders more ammunition if they decide to file lawsuits against you.
