Unpacking and Inspection

After unpacking the Vocal Fix Algorithm Card, save all packing materials in case you ever need to ship the card. Thoroughly inspect the card and packing materials for signs of damage. Report any shipment damage to the carrier at once; report equipment malfunction to your dealer.

Precautions

This is a read only card. Use only with the Lexicon PCM 80, software version 1.10 or higher. To avoid damage to the card, do not expose to rain or moisture, extreme temperatures, direct sunlight, or extreme shock. In the event the card is dropped, damaged, or exposed to liquids, do not insert it into the PCM 80.

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 going 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).

Vocal Fix Card Operation

The Vocal Fix Algorithm Card is a standard PCMCIA card designed to be used with the Lexicon PCM 80 (version 1.10 or higher). Care and handling of the card, as well as some routine precautions are noted here. Please review these before using the card to avoid damage to the card, as well as abnormal behavior in the PCM 80. Refer to your PCM 80 User Guide for information on troubleshooting the PCM 80 itself.

The Vocal Fix Algorithm Card is designed for use ONLY with the PCM 80 V1.10 or higher.

The Vocal Fix card is a Read Only Memory Card which cannot be overwritten. It will only load properly into PCM 80s running 1.10 or higher software.

Handle cards with care.

Do not bend the card, or subject it to moisture, extreme temperature, direct sunlight, or extreme shock.

Insert card completely before attempting card operations.

Incomplete card insertion can cause abnormal behavior.

Do not press EJECT while loading the card.

If the card is inserted before the PCM 80 is powered on, wait for the completion of Power On Diagnostics and the loading of the first program before attempting to use or remove the card.

Card algorithms will be loaded automatically into the PCM 80 on power on. Removing the card before the completion of the normal PCM 80 power on cycle may cause abnormal behavior.

Care and Handling

Card Insertion

Operational Behavior

Once the algorithms have been loaded from the card, you can either remove the card, or leave it in the PCMCIA card slot.

While the PCM 80 is running an extension card algorithm, it will not load a second algorithm card.

Recognition of a second algorithm card requires returning to the PCM 80's internal memory by loading a preset or register from one of the internal algorithms before loading the new algorithm card.

MIDI SysEx register dumps require that the algorithm card used to create the effect(s) be loaded.

Be aware that, if you create a bank of registers with effects created from more than one algorithm card, you will need to perform separate SysEx dumps for each card used.

The algorithm used to create an effect must be loaded into the PCM 80 for a SysEx dump to occur. If you do not have the appropriate algorithm card loaded into the transmitting PCM 80, the data for the effect is not transmitted and the following message is displayed:

Can't dump effect Need algorithm card

If you do not have the appropriate algorithm card loaded into the receiving PCM 80 when a valid SysEx for an effect created from a card algorithm is received, the following message is displayed:

Effect unchanged Need algorithm card

A placeholder is transmitted for any register which cannot be dumped due to the absence of an algorithm card. This placeholder contains the program name and algorithm number, but no effect parameter data. This allows an editor to identify registers which were not sent, and the algorithm card which must be loaded to complete the dump. The PCM 80 will always ignore the placeholder, and will display the following message when a placeholder is received:

Effect unchanged No data in dump

Note that registers made from algorithm cards can be freely copied between the PCM 80's internal register bank (R) and RAM card banks (C0, C1, etc.) without loading the algorithm card.
