I've just installed GrandOrgue on (freshly installed) 32 bit Lubuntu on a Dell Optiplex 330 with 4GB RAM. When I run htop after booting it shows 128M used (of 3968M). I then start GrandOrgue and load the Melcer Chamber Music Hall organ. It comes up with 'Out of memory'. The Organ Properties screen shows allocated sample memory 2094M of 3768M. Looking at htop again it shows that GrandOrgue is using 2188M, or 55.2% of available RAM. There don't seem to be any other processes using significant amounts of memory but the integrated graphics may be using 256M (per lspci output, though not 100% sure of how to interpret this). I don't understand why I would get the out of memory error with only 55% usage. Any ideas on why this might be happening? Would I be better installing the 64bit OS?
