In addition to the 35 General MIDI patches (out of 128) covered by the No Budget Orchestra, I'm now adding the 8 Piano patches (ie, Grand Piano, Honky Tonk, Electric Grand, Clavinet, Harpsichord, Fender Rhodes, Wurlitzer Electric Piano). I've got another 40 on the way soon. Plus all the solo orchestral instruments are going to drop soon.
The Grand Piano here is Little Lizard, now further compressed in RAM. This is about 100 times smaller than the original Salamander piano, and should be quite usable even on limited computers.
I made some improvements to the installer. (Alex, download the orchestra_plugins and piano_plugins to see if this solves the resizing problem in qtractor. Also, in reaper, if the window is blank, try resizing it to see if it "wakes up" and draws).
The piano plugins are in pianos_plugins.zip. For 44KHz, the piano waves are in 2 zips -- grand_pianos44khz.zip and other_pianos44khz.zip. For 48KHz, they are in 3 zips -- part1_pianos48khz, part2_pianos48khz, and other_pianos48khz. These will unzip to a single directory named NoBudgetPianos. There is a utility install_pianos.sh you need to make executable, and run with sudo.
