I am using Linux Mint 17.3, 64 bit -- and have gotten G O to work very well on it, and without all the hazards of Microsoft.
I've a computer engineer friend in Seattle who re-compiled the whole shebang to work on LM - and I like it quite well.
Which is the reason I have given up on my copy of Hauptwerk.
Right now, I am attempting to learn the procedure for making organ sets, in order to put the samples of the organ I play each Sunday, a 4m AEolian-Skinner, into an organ set which I may install in my 4 manual console for my home.
This is quite an uphill struggle, and I am searching all the info on doing this. Any suggestions are welcome.
