QSI firmware/sound File ProgrammingOverview:Note well: there are different files for different versions of hardware. When you get the loco info from the decoder using Q2 / Quantum upgrade, the decoder hardware number is shown. It is important to only install files that are compatible with your hardware. Don't try to load a Titan sound file on a Revolution. Don't try to put an HO file on a LS (Large Scale) decoder.There are various versions of software, check CV7 to be sure:v1 through v6 is the Q1 decoder, usually OEMv7 is the Q1a decoder often OEMv8 is the Q2/Quantum 2 / Revolutionv9 is the Q3/Titan. This is the only decoder that runs the ET / "emulation technology" Where to download files:QSI Solutions is out of business, but the web site was still up as of late 2020: You can explore with the Internet Wayback Machine, and use the following url: https://shedaker.wixsite.com/shedaker. Unfortunately most of the downloads are gone. Very little can be retrieved.The QS Industries site is: http://qsindustries.com/ but no G Scale downloads, nor even the Upgrade program or the CV Manager program. Very weird.There is a groups.io forum with some files: https://groups.io/g/QSIndustries/files but still not all the programming software, and not all the sound files.I have created a groups.io forum, not to compete with the QSIndustries forum, but to provide a place for files to be downloaded, and also to investigate some of the latest features that very few people know about. The forum is open to everyone to join: https://groups.io/g/QSI-SolutionsIf you get stuck, email me (please try the links above before deluging me with emails)Getting and loading firmware/sound files:First, install CV Upgrade, so you can download the sound files. (see the page here )CV Upgrade allows you to load a sound file, play some of the sounds, hear the prime mover, and tweak a few things, notably and importantly base volume for sounds. I am not going to make a tutorial here. (but I do intend to do a tips page on this)Note you can install this software and check out sounds without the USB programmer and/or it's driver installed.Note that sound files contain both the firmware for the decoder and the sound file, they are not separately loadable.Revolution Sound Files:These files end in .Q2Here is the page for the Revolution sound files, both HO and LS, note the file numbers.QSI Revolution sound file listing and settingsTitan Sound Files: Titans can use what are called Q2FX files, these are the original Q2 / Revolution files converted for the Titan, and the new .Q3 files, that use the "emulator technology" features of the Titan.QSI Titan sound file listing and settings
