Introduction - Lexicon PCM 80 User Manual

Thank you for your purchase of the PCM 80 Vocal Fix Algorithm Card. The card
contains a Pitch Correct algorithm which is specifically designed to help fix pitch
problems on previously recorded solo vocal tracks. The presets provide a variety
of easy to use tools, many of which are designed for MIDI keyboard control of
pitch correction.
The algorithm combines an intelligent pitch shifter with a PCM 80 Chamber
reverb. While this is a true stereo algorithm, it is designed to work with
monophonic (one note at a time) vocal sources.
Controls for the algorithm are arranged in a PCM 80-type matrix. The audio
parameters are identical to those in the PCM 80. New control parameters are
found in the Control row and a new Pitch row.
As in the PCM 80, some of the 10 presets have one or more parameters patched
to the front panel ADJUST knob, giving you instant control over the primary
aspect of the effect — without going into Edit mode.
We hope you will find the Vocal Fix card easy to use, and a great extension of
the power of your PCM 80. To get the most out of the card, we suggest that you
invest the time to explore this manual. We think you'll agree that the time spent
investigating will reward you with enjoyment of the full capabilities of the card.

Introduction

Note: The reverb mix or level is
turned down or off in all of the Vocal
Fix presets, as the amount of reverb
appropriate for a given application is
very dependent on what else is go-
ing on in the mix. We've already set
the reverb parameters to values that
will work well with the pitch effect -–
all you need to do is turn up the
appropriate reverb parameter (Rvb
Mix or RvbOutLvl in row 1 of any
edit matrix).
