I recently fired up my old Alesis QS6.2 synth after a long hiatus, only to discover the user bank was hosed. Not only did I want those sounds to play with, but they have special significance to me, since I worked on them while I was an engineer at Alesis!
Opening up the unit, I found out sure enough that the battery was dead. It was pretty easy to find a source online at Syntaur, so I ordered a replacement.
Replacing the Battery
Doing battery swap requires de-soldering the existing battery from the PC board, which is not trivial. Ideally, you’d have a good soldering gun and a “solder-sucker” or a good solder wick. I had neither but I got it off, albeit sloppily.
Then, I had to solder the new battery on. Again, if you have a solder-sucker or wick, you can clear the holes of solder and simply drop the battery in. If you don’t, it’s more difficult. Here are the official instructions from Syntaur.
If you’ve never done anything like this before, I recommend taking your unit in to an authorized repair center get the battery professionally replaced.
Finding the QS User Bank
I figured it would then be easy to find the QS6.2 User Bank sysex file online, but it’s not.
Searching through my old computer files, I found it on my computer from when I worked on it!
Here They Are!!
So, as a public service, here are the QS Synth User Bank Sysex files:

To load these into your QS synth, you’ll need a MIDI interface for your computer and some MIDI software. On Windows, I use Cakewalk or MIDI-OX (free). Enjoy!!

p.s., this is the NAMM show display where we introduced the QS6.2 synth back in 2002. I was the engineer in charge of the update from the QS6.1 to QS6.2. I upgraded the D/A converters, improved the analog PCB layout to eliminate hum in the outputs, improved the button layout ergonomics, and updated the colors (from black to silver). Oh, and I re-programmed the user bank!
For Alesis Service
Lots of people have asked me where to get service for their Alesis synths! In the Los Angeles area, we used to work closely with Audio Design & Service in Burbank, CA, and I recommend them for music instrument repair.
