If you are using waveLab to create the instrument bank and wave files, it is able to import binary files into a waveform. The steps would be something like this... - Use a sound editor program (such as AudioZap or USE) to extract a raw waveform from a file. If possible, edit it to be close to 256, 512, 1K, 2K, 4K, 16K, or 32K in length since those are the sizes of the "slots" of DOC memory that the waveform will occupy. (If the waveform is 1025 bytes in length, it will have to go into a 2K slot and will waste 1023 bytes.) - Save just the waveform as a binary file. Exit the sound editor program. - Run waveLAB and import the binary file into DOC memory. You can check DOC status to see how many pages it takes. - Create a new instrument that uses the waveform. Now the fun begins: you'll have to tweak the various parameters to get a good sounding instrument, and also tune it so it is on pitch with other instruments. Hope that this is enough to get you started. -- Dave Tribby
