PCtask haven't any sound emulation
but
PCX have pc speaker emulation.....I remember I tried the game lure of the tempest and worked with sound at real speed
also it seems PCX have soundblaster emulation but I tried and never worked...maybe need to install soundblaster dos drivers
PCX also emulates up to a Pentium and PC-TASK only up to a 486. And PCX could use different bios.
On paper PCX can be seen as better, but PC-task is far better than PCX in practice IMHO
