"This is the best of the 3 different Cat's made. It has the super thick -24 db low pass filter. It has the coolest Sample and hold features. You can S&H osc 1,osc 2, & the filter or any combo of the 3. I really like how the sine waves are on sliders so you don't have to change between them, you can use all of them if you like at the same time. You can even control the the glide with a foot switch. and/or Cv the filter, osc 1 ,lfo. Polyphony - Mono/Duo-phonic Oscillators - 2 VCO's (2 sawtooth, 2 square wave, and 1 triangle) plus 2 sub-oscillators LFO - 1 with sample-and-hold Filter - 1 with sample -and-hold VCA - 1 VCA, 2 EGs- AR and ASDR Keyboard - 37 keys Memory - None Control - CV/Gate Date Produced - 1980-81"

Update via microtonal in the comments:
"There are a few inaccuracies in the description. You can APPLY S&H to VCO1, VCO2 or the VCF. You cannot S&H VCO1, VCO2 or VCF, only Noise or VCO1. Also, there are no sine waves on the Octave CAT.

Note the missing knob caps in the photo. These white knobs are impossible to find today."

"version 1.0. The unit comes with a 160gb hard drive and 256mb of RAM. You can easily upgrade the specs through MUSE. For those of you who do not know what the Receptor is, here is a brief overview.

The Muse Receptor Rev C is a 2U rack-mountable module that runs standard Windows VST instruments and effects. Receptor can process and play back 16 simultaneous audio sources, which can be either internal VSTi instruments or external analog/digital inputs. It can also run up to 57 VST effects at one time. But that barely hints at what you can do with Receptor!

* Play, edit and store VST plug-in effects and instruments on a hardware device
* Incredibly powerful and versatile
* Intuitive mixer-style interface handles up to 16 audio sources at once
* Connects to your Windows or Mac computer for downloading and editing presets
* Comes with free VST plug-ins!

This is the perfect tool for either live performance or in the studio. You can now use all you virtual instruments without the limitations of your CPU."
