I did not have too, I relied mostly on your really bad advice to suggest dBpowerAMP to convert MPC SND to WAV. Probably expected from someone that does not own anything that saves in MPC SND format and then attempts to give advice on it.
Note:
MPC SND is not the same SND format that most commercial convertors consider it.
From

"On Sun MicroSystem NeXT hardware this digital audio format is known as SND. SND can also contain FM and Wave table synthesis data. The SND format also appeared on early Apple computers. The Type 2 SND is the format for actual digitized data."
There are only a handful for convertors that correctly recognize MPC SND format: Awave, Translator (pending?), CDxtract and WavSnd to name most of them. Only one of them is freeware.
