below<\/a>).<\/p>\n\n\n\nExport via the software<\/h3>\n\n\n\n A simple example is already provided with AT3: it is the Digitest<\/em> song in songs\/ArkosTracker3\/digidrums\/Digitest<\/em> (you can also use the Sarkboteur<\/em> song in the ArkosTracker2 folder). It is a simple song with two digidrums (Bassdrum (02) and Snare (03)).<\/p>\n\n\n\nBoth samples are 8 kHz, and triggered via the event tracks:<\/p>\n\n\n\nFollowing the three steps mentioned above:<\/p>\n\n\n\n
Export to AKY<\/h3>\n\n\n\n This is simple and there is nothing to configure, except export as source without<\/strong> encoding an address. Also tick the “generate a configuration file”, though this is optional:<\/p>\n\n\n\nExport events<\/h3>\n\n\n\n Use the “export events” option, with these values:<\/p>\n\n\n\nThe “export only sample-related events” is important because events can also be used to synchronize events to your productions. You don’t want these in your digidrum player! By keeping only the “sample-related events”, only events which has the same number as a sample will be taken in account.<\/p>\n\n\n\n
Export samples<\/h3>\n\n\n\n Finally, export the samples:<\/p>\n\n\n\nBesides the usual “export as” at the bottom, the top section is important. You must follow the values stated in this screenshot:<\/p>\n\n\n\n
\nIgnored unused samples: ticked, to remove the useless data (why waste memory?).<\/li>\n\n\n\n Generate index table: so that the player knows all the sample addresses.<\/li>\n\n\n\n Amplitude: 16, because the samples are on all 4 bits (0-15), maximizing their quality.<\/li>\n\n\n\n Offset: 128, the player relies on an optimization when addressing the PSG. By setting the bit 7 to 1, we save a few cycles.<\/li>\n\n\n\n Padding length: as explained in the digidrum source, extra-bytes must be added, because the player does not stop the sound accurately (checking it would be too slow), so we add a padding at the end to make sure that no “crappy” values are sent to the PSG. The value depends on how fast the player reads the bytes. 160 is OK for the digidrums player.<\/li>\n\n\n\n Fade-out length: 20, to prevent “clicks” at the end of sample.<\/li>\n\n\n\n Padding\/fade to min value: ticked, so that the “zero” is the same zero as the PSG, once again to prevent clicks and various volume problems.<\/li>\n\n\n\n Export only used length: ticked, as an optimization.<\/li>\n<\/ul>\n\n\n\nListening to the result<\/h3>\n\n\n\n You should have 4 files (or 3 if you didn’t export the “player configuration” in the AKY export). Feed them to the digidrum tester, replacing the currently used files:<\/p>\n\n\n\nCompile it with Rasm, and enjoy the result!<\/p>\n\n\n\n
Export via command-line tools<\/h3>\n\n\n\n More streamlined than clicking on various buttons in AT3, the CLI tools are powerful and allow you to create a build chain, reusable at will. They are in the “tools” folder.<\/p>\n\n\n\n
