Programming the Presets

How to Program Presets

PS1500 contains 64 Programmable Presets stored in ROM memory. 32 of these are factory- programmed to recall various combinations of keyboard sounds (maximum 3) for real time play- ing. The remaining 32 are “empty”, ready to re- ceive user-programmed data. In the Appendix, you’ll find a table showing the names of the fac- tory set Presets, the memorized Sound combi- nations and keyboard mode.

This section describes the most common changes that can be applied to the Programma- ble Presets.

Once a Preset has been modified, it can be saved to RAM by pressing STORE PRESET. Without saving, the modifications remain temporary and are lost when you select a different Preset, or reselect the same one.

NOTE: The STORE PRESET operation is not valid for the GRAND PIANO preset.

HOW THE SOUNDS ARE ARRANGED

In default conditions, the Presets recall factory- set Sound combinations. You can change one or more Sounds of any Preset and store the modi- fications to memory so that the Preset recalls your preferred Sound combination when it is selected.

The Sounds are arranged in 16 Groups of 3 Banks each. Each Bank contains 8 Sounds.

The Sounds of Bank 1 are arranged according to General MIDI standards, while those that reside in other Banks (2 and 3) are variations of Bank1. The table shown opposite lists the PS1500 Sound Group names.
