The VProm was originally based on THE killer drum machine in town back in the early 80s, this expensive drum computer was also the first to include real drum samples back in the days!
Early sample based drum machines used samples of acoustic drum sounds recorded on the fly through some basic hardware. The way they were recorded without any kind of anti-aliasing makes them cut better in a mix than anything available at the time, they sounded so great that they became an alternative to the analog drum sounds of that era. To this day, the unique sound of this vintage machine is highly regarded because only using samples of the analog output is not enough to reproduce the wide range of sound and character of this beast. One DAC(converter)and clock per voice and yummy filters! Yes it is a historical piece of gear that take a huge place in the 80s sound picture. Only around 500 of these things are out there so don’t count on finding a working one easily and forget for cheap.
It has been used by major acts like: Prince, Phil Collins, Thompson Twins, Stevie Wonder, Gary Numan, Depeche Mode, The Human League, Jean-Michel Jarre, Vangelis, John Carpenter, Todd Rundgren,The Art of Noise…
VPROM accurately reproduces the internal circuitry and filtering of the first legendary Drum Machine but is also perfectly able to read and import original, custom or vintage EPROMs from other Drum Machines of that era, legendary 80s machines such as the Linndrum, DMX, DrumTraks etc.(.bin files that you can find on the net) An EPROM is an integrated circuit that was used to store short audio sample data in a compressed format. VPROM is the closest thing to the real deal – reading and decoding original EPROM data images in real time using the exact decode table from the AM6070 DAC at a variable sample rate. VPROM also allow experimenting with your own sample database. You can convert samples with external tools and load compatible ULaw companded images (see manual for more info).
