pyMPC2000xl
A Python reader/writer of Akai MPC2000XL *.PGM and *.SND files.
inspired by https://www.midicase.com/mpceditor/ (only I wanted a little more control).
Here's what I started with:
The MPC2000 and other related models use DOS formatted disks.
Samples are saved with a .SND extension and contain 16-bit signed data after a 42 byte header:
Length Format Description
----------------------------------------------------------------------
2 1,4
16 ASCII Filename (without extension, space padded)
1 0
1 unsigned char Level 0...200 (default 100)
1 unsigned char Tune -120...+120
1 unsigned char Channels: 0=Mono 1=Stereo
4 unsigned long Start
4 unsigned long Loop End
4 unsigned long End
4 unsigned long Loop Length
1 unsigned char Loop Mode: 0=Off 1=On
1 unsigned char Beats in loop 1...16 (default 1)
2 unsigned short Sampling frequency (default 44100)
MPC2000 programs have a .PRG extension and are partially described here:
Length Format Description
----------------------------------------------------------------------
2 7,4
2 unsigned short Number of samples 1...64
1 0
Repeat for 64 samples...
16 ASCII Sample Name
1 0
2 30,0
16 ASCII Program Name
15 0,136,120,12,45,0,20,206,50,0,35,64,0,25,0
Repeat for MIDI notes 35...98
1 unsigned char Sample 0...64 (255=none)
24 0,44,0,88,0,0,0,0,0,0,0,0,0,100,0,0,0,0,100,0,0,0,0,0
388 6,0,100,50,100,0,0...(see .PGM file)
Repeat for Pads A01...D12
1 unsigned char Note number 35...98
