The S950 is a rack-mountable 12-bit sampler with 8-note polyphony, a 48 KHz sampling rate and up to 2.25 MB of RAM. The S950 was the first Akai sampler to implement time stretching which enabled the user to alter sampling length without altering pitch. This along with standard features like crossfade looping and pretrigger recording made the S950 a superior sampler for it's time.
