[LAU] starting Bristol with scala

Hello, All! I'm running UbuntuStudio 18.04 and am using this command to start bristol: startBristol -b3 -scala ji_12.scl I got bristol from the repos, which is completely up to date.. The scala file is in .bristol/memory/profiles. The problem is that I hear no difference in the chords. That's the just intonation that Robert Rich used for Geometry, and the A-flat and G-flat chords should be particularly spicy. I've pointed the command line to the specific file in my scala folder, but the output tells me that bristol can't load the file ji_12.scl.scl. I'm not sure why it adds the suffix. What am I missing? Also, if anyone knows of a Hammond emulator that is compatible with scala, I'd love to hear about it. That's the real goal. Bill
