The Sample Vision SMP file format.


Sample Vision is a program used by professional musicians to send and receive samples via a MIDI interface to the PC. While on the PC, you can edit several parameters including loop points, pitch, time compression, normalize, sample rate, ect. The list of supported samplers include: AKAI {S700,X700,S900, S950,S612,S1000/1100}, Casio{FZ1,FZ10M,FZ20M}, Ensoniq{EPS,EPS16,ASR10,Mirage}, Emu{Emax,EmaxII}, Korg{DSS1,DSM1,T workstation}, Oberheim DPX-1, Peavey DPM-3, Roland {S10,MKS100,S220,S50,S330,S550}, Sequential Circuits Prophet 2000/2002, Sample Dump Standard devices, Yamaha TX16W.
