The MAST2 Page

2.Set the Input parameter to a value of Analog.

3.Set the value of the Source (Src) parameter to External (Ext).

4.Set the value of the Mode parameter to LiveIn.

5.Verify that mic signal is on the left side only. Adjust the Gain parameter as needed, to get a good signal level.

6.Verify that your sound source (either the K2661 or external source) is on the right side only.

7.Go the Effects-mode page and make sure that the FX Mode parameter is set to Auto and the FX Chan parameter is set to Current.

Enabling Vocoder Mode

1.Load the file VOCODER.K26 into any bank. It’s provided on the CD-ROM and SmartMedia card. See Chapter 13 if you need help loading a file.

2.Go to Master mode.

3.Press the MAST2 soft button.

4.Set the value of the Vocoder parameter to On.

5.Exit from Master mode (press any of the other Mode buttons).

Note that enabling the vocoder activates special software, which replaces the software used for the SHAPE2 and AMP MOD OSC functions in the F3 block of an algorithm. Therefore any programs that use SHAPE2 and AMP MOD OSC in the F3 block will sound different while the vocoder is active. Turning the Vocoder parameter Off will restore those DSP functions and disable vocoding.

Using the Vocoder

Go to Setup Mode and select one of the setups in the memory bank where you just loaded the vocoder file. If you are using an external sound source for your slave, choose the setup Vocoder- ExtSlave. If you are using the K2661 as the input source for the slave, then you can choose either Vocoder-22 Band or Vocoder-20 Band. The 22-band vocoder will allow you to play up to 4 voices of polyphony on the slave program; the 20-band vocoder will allow you to play up to 8 voices of polyphony on the slave program.

Play a note or chord on your keyboard and speak into the microphone. You should be able to hear what you are speaking, but the sound will be a string sound (assuming you are using the K2661 as the slave source), pitched to the note or chord you are playing.

Try moving Sliders A, B, and C, and listen for changes in the sound. Since the setups contain entry values for these sliders, you may have to move the slider across its full range before it begins to take effect.

Effects Issues and Output Issues

The studio assigned to the vocoder setups is configured in the following manner: If you are using the K2661 for the slave signal, the slave program (in zone 3) has its output assigned to KDFX-B, which is being routed to the FXBus2, with no effect. On the OUTPUT page in the Setup
