Btw, this software is not NTSC only. If you run the file "setup" and select Joystick on a PAL machine, the PAL version is installed.

The following message appears when running setup:
"Ah, I see you're not in the States.
Installing PAL version....
Digimaster setup complete."

If you then run the program, the version number on the screen will display: "1.0jp".

I will therefore remove the NTSC only flag that was set.

I've checked the DigiMaster routine and it makes use of the same behaviour of the SID than the player of SounDemoN and THCM. It uses the $00 waveform and the test bit in almost the same way.

The routine from DigiMaster is:

LDA ($2B),Y
BEQ $22A8
STX $D404 ; X = $11 here
STA $D401
LDA #$09
STA $D404
LDX #$01
STX $D404
LDX #$05
-
DEX
BNE -
LDX #$11
LDA #$00
STA $D401

The routine from THCM (based on Voice 1):

LDA #$11
STA $D404
LDA #$09
STA $D404
LDA $B800
STA $D401
INC $4B
LDA #$01
STA $D404

The difference is that DigiMaster writes the frequency data before the test bit is set and zeroes the frequency after the test bit is cleared.

Thanks Moloch, I was also under the same impression as Groepaz that this wasnt a scene release, that the author had released this himself to PD. I changed this to an uncredited crack/spread.

This software was sold by CMD for years, and yes, it was for the NTSC market

Does it also make use of waveform $00, like SounDemoN did?

the disk i/o seems very unstable - my guess is that the requirements include some kernal that allows sprites enabled when loading (like speeddos)

Added a d64 with recovered 3 deleted files
43 "DM"                *DEL  24;02
 2 "64PLAYER"          *DEL  10;05
 3 "128PLAYER"         *DEL  10;06

else it didn't even load. Anyway I can't seem to be able to use it, after trying to load a sample with File/Load, pushing "MORE" to scroll dir and selecting a sample name, for example "MONKEY", it hangs after displaying a waveform.
Side 2 contains 3 SDA files but 2 are broken due to bad t/s links.

Interesting digi playback routine for playing 8-bit samples which is described in the below description as "revolutionary method". It toggles the test bit of the control register and changes the hi-byte of the frequency of one of the voices to play 8-bit samples. Similar kind of technique like discovered by SounDemoN in 2006 (New waveforms...) but this was done in DigiMaster in 1993.

Product description:

-------------
Digimaster is a unique software product which allows you to process digital audio on your Commodore 64.

This advanced software utilizes a fully graphical interface with pull-down menus. Incorporated into its operation are many powerful features, such as Cut, Copy, and Paste, which makes editing sound as easy as editing text in a word processor. Using an optional audio digitizer [like the Sound Ultimate Xpander 6400], live sound can be grabbed into the computer, edited, and then saved to disk. There is even a utility included which will convert Amiga sound samples, giving you access to a vast library of sounds.

Probably the most impressive feature of this software is its ability to replay sounds in true eight-bit digital audio on your Commodore 64 without the need for extra hardware. This is made possible by a revolutionary method of controlling the sound chip inside the Commodore 64. The result is crystal clear audio reproduction.

Digimaster Features:

Fully graphical interface

Many powerful editing functions

Ability to replay sounds in true eight-bit digital audio without the need for extra hardware

Included software which allows replaying sounds from your own programs

Requirements:

Commodore 64 or Commodore 128 computer
Commodore 1541, 1571, or compatible disk drive
Joystick or mouse (mouse highly recommended)
