DMP.DOC Documentation for the Dual Module Player v2.72 Copyright (C) 1992,1993 Otto Chrons DMP.EXE is a program demonstrating the capabilities of the DSMI programming interface (DSMI stands for Digital Sound & Music Interface). It's a standalone module player with which you can play STM (also S3M,669) files as well as Amiga modules (MOD or NST). DMP is cardware so you can freely distribute it and I hope you did, as long as you include this help file with the executable. If you like the product, please send me a postcard to the address shown on the endscreen of DMP!! Here is the command line syntax: DMP [options] [modulename] [@listfile] [options] Where: ------ modulename : name of a module (wildcards *,? allowed) listfile : name of a file containing list of module names options : -Sxxxx set sampling rate 4000-44100 alternatively 4-44 -H or -? show help screen -Ix interrupt number -Pxxx port address (use 42 for PC speaker) -Dx DMA channel -O Scramble module order -L Inhibit looping -M Mono mode (SB16 & PAS) -Q Quality mode (on 8-bit cards only) -Cx Desired card where x is: 1 for Sound Blaster 2 for Sound Blaster Pro 3 for PAS+ 4 for PAS16 5 for SB16 6 for general DAC (Covox) 7 for Aria cards 8 for Windows Sound System & compat. 9 for Gravis Ultrasound 10 for PC Speaker 11 for Stereo DAC (LPT1 & 2) 12 for Stereo-on-1 DAC -Txxx Buffer size xxx (0-32000) -E Disable extended tempos (MOD only) -Axxx Amplify by xxx, 31 is normal volume -B Disable EMS usage -8 Force an 16-bit card into 8-bit mode (works with Aria, PAS16 and WSS) -Nxx Set default panning to xx (0-63,100) 100 = Surround channel -W[command] Automatic DOS shell, executes optional 'command'. If you use some options all the time, you can put them into an environment variable DMP: Example: You always want to use quality mode and sampleing rate of 22kHz and mono mode, put following line into your AUTOEXEC.BAT SET DMP=-q -s22 -m NOTE! You cannot override single letter options (-l,-o,-m,-q) with command line parameters. All other options can be overriden. You may have to give your soundcard's IRQ number and/or port address if DMP fails to find them. If you don't provide both values then DMP will assume 220h for port address, and 7 for interrupt number. Giving wrong address will hang your machine, but wrong interrupt number only stops the playing after a second. The "/C" option is useful if you want to use some other card, than the one DMP automatically detects. You don't have to add any extension to the name, because the program will try extensions AMF, STM, 669, S3M, MOD and NST if it doesn't find the file. Note that you can supply many modulenames and list files, up to the internal limit of 1024 modulenames. Example: DMP beyond -s20 *.NST @goodmods goodmods is a text file containing following lines: occ-san stars intro3 DMP will use the sampling rate of 20KHz and play following modules: BEYOND.MOD, OCC-SAN.STM, STARS.MOD, INTRO3.MOD and all .NST-files in the current directory. Using stereo DACs If you have two DACs on LPT1 and LPT2 you can use them as one stereo source with following command line: DMP -c11 ... Note that you don't have to specify port address. If you have a Stereo-on-1 DAC you can use it with following options: DMP -c12 -pXXX ... where XXX is the address of the DAC (LPT1 = 378) How to use DMP After DMP has loaded the first module, it starts to play it and shows some information about it. DMP displays module's name, its file size, the amount of memory used for module and sampling rate. Because of the AMP's Intelligent Module Loader (IML) modules usually take 10-30% less space. I've seen a 244Kb module shrink into 151Kb when I loaded it with DMP. While playing, DMP updates fields showing current pattern, row, elapsed time, volume and sampling rate. Under these fields are four lines showing the current status of the corresponding tracks. Here is an example: ������������������������������������������������������������������������� bassdrum � F#2 � 64 � � ��������������������� strings7 � D-3 � 20 � ARPEGGIO � ��������������� guitar42 � E-2 � 12 � PORT.NOTE � ����������� guitar44 � G-2 � 57 � FINE VOL � ������������������ ������������������������������������������������������������������������� The first field shows the instrument currently playing on that track. Second is the note value, third its volume and fourth indicates what special command is running. The bar simulates a VU meter on music equipment, but you shouldn't take it as an exact representation of the music level, it's there because it looks nice! The rest of the screen is filled with instrument names. The numbers before an instrument name indicate the channels that instrument is playing on. Pressing 'H' brings up a quick-help showing command line options and keys used to control the program. Keys : �������� P pause module, any key resumes 1-9 turn track xx on/off 0 turn selected track on/off D DOS shell (write EXIT to get back) N load next module (if you have supplied more than one) S stereo mode on/off (SB Pro), default is on F filter on/off (SB Pro), default is off left/right Jump to next/previous pattern up/down select track F1-F10,+,- set volume [,] Set new speed {,} Set new tempo V Real/fake volume bars L,M,R,U Panning full left/mid/right/surround , . Panning left/right H Help screen ESC exit Try this module player with all the modules you have, and if you encounter problems with any modules, inform the author.

See DMP.REV for revision history. ���������������������� For programmers only ���������������������� DMP was created with Borland C++ 3.1 and it is based on DSMI's routines, so by ordering DSMI interface you could write programs with similar capabilities. DSMI is a collection of routines (for C and Turbo Pascal) that allows programmers to play modules in the background, but unlike any other module player it also allows simultaneous sound effects!! Up to 32 channels can be used which means that you can have a module and sound effects playing in full stereo (on cards which support stereo sound)! DSMI is available and the price is 270FMK ($70). Packet includes full documentation (printed), OBJ files & libraries for C version, TPUs for Turbo Pascal and also most of the source code so you can modify the behaviour of DSMI.
