    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.

  • Page 5: Vocal Fix Card Operation

    Handling the 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, Algorithm 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.
  • Page 6 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...

    Extensions now available If the PCM 80 is running an algorithm from a different extension card: Loading a different algorithm card requires returning to the PCM 80's internal memory by loading a preset or register from one of the internal banks.

    Loading the Vocal Fix Presets Once the software is loaded, the PCM 80 will have access to the program bank on the algorithm card. This extension memory banks is labeled with an X. Press Program Banks repeatedly until the X bank is displayed. This will follow all of the PCM 80's internal Program banks.

  • Page 9: The Pitch Correct Algorithm And Its Parameters Overview

    Much of the art of pitch shifting, therefore, is in determining the appropriate intervals for sampling and the optimal points for splicing. As the PCM 80 Vocal Fix card gives you significant control over these operations, you may find it...
  • Page 10 MIDI control is straightforward. Just connect a MIDI keyboard to the PCM 80 MIDI IN jack, set the keyboard and the PCM 80 to the same MIDI channel, and you're ready to start. Don't try to play the melody note-for-note — just [ress the keys needed to correct bad notes.

  • Page 11: The Chamber Reverb

    The Pitch Correct Algorithm and Its Parameters The Chamber reverb produces an even, relatively dimensionless reverbera- The Chamber tion, with little change in color as the sound decays. The initial diffusion is similar Reverb to the Concert Hall algorithm, but the sense of space and size is much less obvious.

  • Page 12: Parameter Descriptions

    GldResp This parameter is similar to the GldResp parameter found in the Master Delay parameter of several PCM 80 delay and reverb algorithms. It sets the pitch shifter’s responsiveness to the pitch detect source and also to modulation by internal controllers (LFO, AR etc.) and MIDI controllers (aftertouch, velocity, etc.) At the highest setting (100), the pitch will track the detect source very...
  • Page 13 The Pitch Correct Algorithm and Its Parameters Tracking This parameter controls how quickly (accurately) the pitch detector will follow pitch changes in the detect source. This control can be set to Fastest, Fast, Moderate, Slow or Hold. Fastest This is generally the most useful setting as it provides accurate tracking as well as good handling of vibrato or pitch bends.
  • Page 14 PCM 80 Vocal Fix User Guide Lexicon Shift Cents Shift Row This parameter determines the amount of fixed shift for the stereo input channels. The value is given in cents (1 cent=1/100th of a semitone, 1200 cents/ octave). The range is adjustable in increments of a single cent. This value can be modulated smoothly with patch sources to create vibrato and other pitch- related special effects.

  • Page 15: Using The Vocal Fix Programs

    General Procedure In general, the track with errors is routed through the PCM 80, processed by one of the Vocal Fix presets and re-recorded. Depending on the number and type of errors on a given track, it is possible to fix the vocals in one pass. Typically, however, you may need to make several passes, fixing a particular note or approx.

  • Page 16: Preset Descriptions

    Double Effect ADJUST: On/Off This preset produces an alternative double track effect. Mix the output of the PCM 80 with the original vocal track. Use ADJUST to randomize the amount of delay and pitch difference between the original and processed tracks.
