A hard-coded counter (line 140) will stop the BASIC program at the end of the tune. RUN the BASIC program to play the dual-SID tune. d64 image file, then click the Open button. In VICE, select ‘Settings’->’Settings…’, ‘Audio Settings’->’SID Settings’, and (assuming you didn’t change the SID base addresses in gt2stereo.cfg) choose SID #2 address to be $d500.įinally, in VICE, select ‘File’->’Attach disk image’ to navigate to the. Line 50 of the driver program sets the end of basic to be $1000 (minus one), which stops the BASIC code, and any normal vars, indexed vars, and strings from encroaching into the music routine (which lives at $1000). When tokenized (made C64-native), the BASIC program is 317 bytes long and lives at $0801. Note: If you plan to script the creation of these kinds of BASIC programs, you can use the provided gen_prg.py module to created C64-native PRG files. confirm that the paste worked with the LIST command.

.

In VICE, select ‘Edit’->’Paste’ (Note: The lowercase text will be converted to uppercase when pasting).

If you plan to script some of the steps of creating disk images and placing generated files into them, you can use the python subprocess module to automate calls to the c1541(.exe) command line utility.Ĭopy-and-paste the following BASIC music driver program into a running C64 VICE instance:.

On windows, we recommend using DirMaster for.

The file should now appear in the image without the “.prg” filename extension, and should be a file of type PRG. Best to change the filename to all lower case before adding to the image. d64 floppy disk image and write the lechuck.prg export to that image. This appends a two-byte load address of $1000 to the binary before exporting. So RAM at $1000 is a common default for music routines.Īccept the default format “PRG - C64 native format”. 4KLang VSTi, Goat Tracker, Jeskola Buzz Tracker, Plogue Chipsound DEMO, Renoise DEMO.

Note: The VIC-II chip cannot “see” the 4K of RAM that starts at $1000 or $9000 (the PLA maps the character ROM to those ranges). KVR Audio Forum - Plogue OPS7 (bit-accurate DX7 emulation).

ChiptuneSAK supports both versions, automatically selecting the version based on the number of voices. GoatTracker comes in two versions: the original, which can play 3 voices with one SID, and a stereo version, which can play 6 voices using 2 SIDs.

To make the notes play at the desired pitch, the song must be encoded in PAL mode. Note: GoatTracker does not have separate frequency tables for PAL and NTSC, which means that the notes played back in NTSC mode will not be tuned to the standard A440 tuning used by ChiptuneSAK. As a result, to take advantage of either, music should be exported to the sng file, opened in GoatTracker, and any adjustments made there. The GoatTracker sng file format does not contain information about the target architecture or whether the song requires multispeed. The GoatTracker class is designed to convert between the GoatTracker sng format and the RChirp Representation. sng format to the various native Chirp representations.

ChiptuneSAK can import and export GoatTracker song files in the.
