This megapack of instruments for Aly James Lab's VPROM (formerly VLinn) includes preset kits and banks in FXP and FXB format that can be loaded into VPROM.The eproms are the instruments that are loaded under "PROM" on the VPROM VST, and they are .bin format, which is the file type the VSTs read for eprom loading. There are over 150, hats, kicks, snares, fx the works. These are drum sounds I've created and tweaked over 2 years of producing. There are about 4 banks that include a few combos of these various eproms, and 4 presets that match them. The eproms can be loaded and tweaked to create and save thousands of kit combinations.PLEASE REFER TO THE OFFICIAL MANUAL VIA THIS LINK FOR INSTRUCTIONS ON USING VPROM'S EPROM FEATURE.PLEASE NOTE: although the bin files can also be loaded into VSDS-X, there is only ONE eprom slot available on the VSDS-X in which to load a custom instrument bin file. DO NOT load VPROM presets into the VSDS-X.
