Audio integrated circuit maker Sound Semiconductor let us know that the new Dave Smith Instruments Prophet X features their SSI2144 Fatkeys Four-Pole Voltage Controlled Filter – an updated version of the classic SSM filter that was used in many classic analog synths.
The SSI2144 is an updated and improved re-issue of the SSM2044, which many believe to be the best-sounding filter IC ever produced. The original version of the filter was used in many classic instrument designs, including instruments made by Crumar, E-Mu, Korg & PPG.
Both the original SSM2044 and the updated SSI2144 were designed by electronic music instrument pioneer Dave Rossum.
“SSM chips were at the core of Rev One and Two Prophet 5’s,” stated Dan Parks, President of Sound Semiconductor. “So it feels great to be back in a Prophet our the new SSI2144.”
Here’s an interview with Parks from earlier in the year, when he debuted Sound Semiconductors and their new chips at the 2018 NAMM Show:
Sound Semiconductor was founded in 2016 by original SSM staffers, to develop high performance ICs for professional audio and electronic music. More information is available at their site.
