Reply to "PS-1 vs. QSI Q2+"

QSI's system was first. MTH licensed a slightly dumbed-down version (to control cost) of Q2+. Interestingly, if you listen to early HO BLI steam locomotives, you will hear those same QSI sounds. The whistle clip is very distinctive. Pre-TMCC, QSI dominated the electronic reverse unit/sound market. Their systems could be found in MTH, Weaver and 3rd Rail locomotives.

And a few Lionel engines too. Recorded sounds are very much the same. The board software and firmware was different for different functional control. I do believe MTH had PS-2 in mind anyway and that was limiting what they wanted to do with PS-1. G
