There is a new heavy steam file for LM-1 modules, which have limited storage compared to the LM-2s modules. The previous version takes up a lot of room in the module, leaving little room, if any, for other sound files. I had mentioned this to Tim last year. The new file sounds pretty good- similar to the previous one, and includes the compressor, but not the turbo. I was able to add coal and water sounds. There is still not enough room for the blowdown, but it's an improvement.
