Customizing The Effects Settings - Kurzweil PC88 A Step By Step Manual

PC88 Made Easy

12. Customizing the Effects Settings

This tutorial will explore customizing the effects parameters beyond the buttons
available on the front panel Effects section. This tutorial is designed for the PC88MX,
since it shows using both the Internal and VGM effects processors. If you have a regular
PC88, you can still follow this tutorial, but simply ignore the steps that refer to zone 3.
1. Create a three zone layered Setup, following tutorial #1. In zone 1, for the Program,
select #44 Marimba from the Internal Voices Bank. In zone 2, for the Program, select #60
Metal Marimba from the Internal Voices Bank. In zone 3, for the Program, select #4
Electric Piano 1 from the GM Bank.
2. If zone 1 is not currently showing in the display, press the Zone 1 button. Now, using
the buttons in the Effects section, select Room for the Reverb Room Type and Bright for
the Reverb Quality.
3. Press the Zone 3 button. Using the buttons in the Effects section, turn off the Reverb
and select Chorus 1.
4. Press the Zone 1 button again. Notice that the buttons switch to show Room Bright for
the Reverb, with No Chorus. Press the Zone 2 button. The effects settings stay the same.
It is important to understand that there are two separate effects processors in the
PC88MX. (If you have a regular PC88, you have only one effects processor). These
effects processors are completely independent and function only for specific programs.
The Internal Effects processor controls all the sounds from the Internal Voices Bank. the
VGM Effects processor controls all the sounds from the GM, Expansion Voices, and 64
Note Poly banks.
This also means that ALL programs controlled by a specific effects processor will use
the same effects. So if you have two zones in your setup using the programs in the
Internal Voices bank, making a change to the effects in one zone will actually be changing
them for both zones. That is why when you switched from zone 1 to zone 2 in this
setup, the effects didnÕt change, but switching from zone 3 to zone 1 did show a change.
5. Press the Effects button in the Zone Parameters section. The display now shows
Zone:2 0:060, IntFx: RoomBright. Notice that the display shows the same values you
selected from the dedicated effects buttons. Making any changes there will affect the
display, and vice versa. Press the Quality button once to change from Bright to Normal.
Notice that the display has changed to show RoomNormal. Move the alpha wheel one
click to the right. The display now shows RoomNormal+Ch1. Notice that the Chorus 1
button has now lit up. Move the wheel back one click so it is again set to RoomNormal.
6. Press the Zone 3 button. Notice that the display still says RoomNormal but the effects
buttons show no reverb and Chorus 1.
The reason that the display and the buttons donÕt match is that the parameter we are
looking at in the display is for the INTERNAL effects, but this zone is playing a program
from the GM bank, which would use the VGM effects. Press the Chorus button to select
Chorus 2, and notice that the display still does not change.
