Want to know more about this product, then read this review published on the Gear Slutz web site :

The Lexicon PCM70 is an effects rack with chorus, flange, reverb, multiband delays and resonate chords. With a mono feed in and stereo effect out, it’s heritage is from the Lexicon 224X and was one of the first effects processors to offer MIDI implementation. The Preset Programs are set up in Rows

Row 0 - Echo and Chorus Programs
Row 1 - Multiband Delay Programs
Row 2 - Resonant Chord Programs
Row 3 - Concert Hall Programs
Row 4 - Rich Chamber Programs
Row 5 - Rich Plate Programs
Row 6 - Inverse Room Programs

When I bought mine in 1986 it came with version 2.0 software. I found the presets in this version were what made thePCM70 such a classic. The names themselves are sort of what you would expect: Concert Hall, Long Hall, Gymnasium, Rich Chamber, Small Room, Tiled Room, Gated Chamber, Infinite Reverb, Rich Plate, Small Plate, Gated Plate Etc. But the sound is exquisite.

Later a version 3.0 software was released which added the Inverse Room Program and included 42 new presets as well as better MIDI implementation. But If you wanted to keep the presets from an earlier version they needed to be saved in a user register before installing the new chips. That's right the software update was on 3 chips that would replace existing chips. 

The PCM70 encourages user interaction and tweaking of parameters with the large soft knob, up, down keys and the 0 through 9 number keys. Each algorithm contains between 25 and 35 parameters that create a preset. Included in thePCM70 are 50 user register locations to store your own presets.

At the time the PCM70 was introduced it was unheard of for an effects processor to incorporate MIDI. Lexicon was looking ahead when they chose to add this feature. MIDI can be used for patch changes or real time changes like panning, feedback amount, reverb time etc. up to 10 parameters. With a computer MIDI can be used for patch editing using third party software and system exclusive messages.

The PCM70 is a great effects processor, well known for Its classic sound. Those rich, smooth Lexicon reverbs, and the multiband delays are just wonderful. In a time when plugins seem to dominate the effects we use there is still room for hardware processors like this.
