About this video

Several Aztech Sound Galaxy NX Pro 16 ISA sound cards get repair attempts and are then tested with MPU-401 and Roland MT-32 emulation through SoftMPU.

Good to know: Repair work may involve soldering: burns and fumes, and old solder contains lead.

Why watch it

SoftMPU and MT-32 emulation are as much the subject as the repairs, with MPU-401 mode tested as well, all on the same Aztech card model.
