SMP
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.
The SMP format breaks down like this:
| Offset | Size | Description | |||
| 000 | 18 | 'SOUND SAMPLE DATA' ASCII FILE ID | |||
| 0018 | 04 | '2.1 ' ASCII FILE VERSION | |||
| 0022 | 60 | USER COMMENTS 60 ASCII CHARACTERS | |||
| 0082 | 30 | SAMPLE NAME LEFT JUSTIFIED 30 ASCII CHARACTERS | 0112 | 04 | SAMPLE SIZE SAMPLE DATA COUNT IN WORDS |
| 0116 | ?? | SAMPLE DATA 1 WORD PER SAMPLE, LEAST SIGNIFICANT BYTE |
FIRST, LSW FIRST; SIGNED 16 BIT INTEGERS
?? 02(DW) RESERVED
?? 04(DD) LOOP 1 START USE SAMPLE COUNT NOT BYTE COUNT
?? 04(DD) LOOP 1 END
?? 01(DB) LOOP 1 TYPE 0=LOOP OFF,1=FORWARD,2=FORWARD/BACKWARD
?? 02(DW) LOOP 1 COUNT TIMES TO EXECUTE LOOP BEFORE NEXT LOOP
THERE ARE SEVEN MORE IDENTICAL LOOP STRUCTURES FOR A TOTAL OF 8
?? 10 MARKER 1 NAME ASCII MARKER NAME ?? 04(DD) MARKER 1 POSITION FFFF MEANS UNUSED
THER ARE SEVEN MORE IDENTICAL MARKER STRUCTURES FOR A TOTAL OF 8
?? 01(DB) MIDI UNITY PLAYBACK NOTE MIDI NOTE TO PLAY
THE SAMPLE AT ITS
ORIGINAL PITCH
?? 04(DD) SAMPLE RATE IN HERTZ ?? 04(DD) SMPTE OFFSET IN SUBFRAMES ?? 04(DD) CYCLE SIZE SAMPLE COUNT IN ONE CYCLE OF
THE SAMPLED SOUND. -1 IF UNKNOWN
(DD) 4 BYTES, LS BYTE FIRST, LS WORD FIRST (DW) 2 BYTES, LS BYTE FIRST (DB) 1 BYTE
That's about it. One thing I have noticed is that Sample Vision only writes seven loop structures to file as opposed to the eight structures it claims are written.
