Thanks. The gui conflicts were one of my latent hunches.
Regarding the examples' playability, the Lesli 'setup' button does not work, but I did not hoookup a keyboard.
I took for granted, all examples that can be used with MIDImetadata would have the internal keyboard as an alternative controller. Was I wrong? I'll go again with a MIDI keyboard connected.
I tried running the B6.csd from the command line, but got the usual text readout.
One thing, though. There was an error message:
"WARNING: could not open library 'C:\Programs Dump\Csound6_x64\plugins64\py.dll' (-1)"
I thought an error may have occurred when I installed Csound in a non-standard directory.
I think my primary goal, now, is getting all the old examples from Mikelson, Comajuncosas, Pinkston, and others, that worked in older versions, including Maldonado's CsoundAV, to work in the current version. That depends, I think, on finding a workable front end. I thought QT was the best choice. I can still get Maldonado's version up and running with a minor change in the boot switches, but think an update would be better. Granted, I was using these instruments in 2001 and earlier, but I still think they are viable, especially from performance, and academic points of view.
