I wonder if someone recommends a VST that emulates those old MIDI sounds of the old sound cards?
I want to make a track in the old style video games, but I like those poor sounds of trumpet, strings, etc.
In time, it has to be worse than the sounds of the TTS-1 

Maybe not exactly what you asked for, but one option might be to actually use TTS-1 and then also insert an effect such as Cakewalk AliasFactor. Perhaps some of the presets such as "Cheap Toy" or "Cheaper Toy" might make the TTS-1 sound poor enough for you? The result sounds at least pretty poor to me!

Check out some of the presets in Z3TA
 
I'm 99% sure there's a bank of patches in there that do this.

You could use an SF2 player (e.g. sforzando) and download a nice low quality GM soundfont (something about 1 or 2MBs should be suitably bad).

Check out Plogue - they make some interesting (and VERY FUN) stuff with old chip sounds that emulate early vocal and video game sounds.
 

I think what it was called was 8 bit. 
Not sure about newer windows but it was called the MS wavetable in XP and Sonar can only use it in MME mode.

I tried to use the native Sonar SFZ vst but it's not loading SF2 files... and this topic is telling this... 
 
But reading some posts I discovered that Kontakt can read SF2 files.

I tried to use AliasFactor (Insert FX Chain Present, right?), but for some reason, the only button that is responding is Volume. The other buttons (mode, cut, bit, etc.) do not change anything in the sound ...

Hm, did you insert AliasFactor into the FX bin and then select one of "Cheap Toy" or "Cheaper Toy" from the list of presets? Otherwise, right click in the FX bin and from the menu select "Insert Audio FX" > "LoFi" > "Alias Factor". Finally select your preset from the drop-down list.
 

 

I'm using Platinum, I've never used this plugin, but watching your image, I can conclude that my plugin is corrupted, is this?
