That machine is the Emu SP-1200. If you're not familiar, it's a legendary sampler with a very particular sound and a cult following even to this day.
It was designed by Dave Rossum which some of you in the synth & eurorack world may know for other things.
It has been used on a lot of music, from the first Daft Punk album (they actually had 7 chained in midi for their live performance at the time I believe) to Phil Collins, to most of the big hip-hop producers of the 90's like Pete Rock, DJ Premier, Lord Finesse, J Dilla...
Here it is along with my shoebox prototype and breadboard:
As a fairly long-time user, the two most appealing things to me are the ease of use and intuitiveness of its interface, and its very specific sound and character. Some of which is due to the way it interpolates samples when tuning them up/down, and some due to its analog filter (SSM2044), 12bit AD/DA (AD7541) and output stage.
Most of the original components are now discontinued, except for the SSM2044 VCF which has been reissued and slightly updated in the form of the SSI2144, in partnership with Dave Rossum. I'd like to try and include this filter in my project.
The datasheet for the filter is available here (under Products > SSI2144 VCF)
The service manual for the SP-1200 is available here, it includes all the schematics from page 67 to 88
I have quite a few questions, but I'll start with a couple:
- Would it even be possible to implement this filter in my circuit considering the Arduino & RPi take 5v power but the filter requires 12v? If not can you suggest a good alternative?
- How do I figure out how to wire the pins of the filter?
Any help and feedback will be much appreciated.
