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

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. 

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.
