SECTION 3
PROGRAMMING
INTRODUCTION
In the Prophet VS, responsive physical controllers—key position, velocity and
pressure, the wheels and joystick—combine with an entirely new approach to
timbre generation, to create a performance synthesizer with unrivaled sonic
power and variety, and which also happens to be very easy to program your-
self.
This section explains how to select, edit and store programs. Specic oper-
ations and adjustment procedures for each module are detailed in following
sections.
MEMORY BASICS
To correctly store your programs and use cartridges, you need to know a little
bit about the Prophet VS memory system.
Internal Memory
The Prophet VS has two dierent kinds of internal memory. If the information
can be changed by the player, it is stored in non-volatile random-access mem-
ory (RAM). The term "non-volatile" means that the contents of this memory are
not lost when power is switched o. (This is because of an internal battery with
a very long life span.) If the information is of a permanent nature and cannot be
changed by the player, it is stored in permanent read-only memory (ROM).
There are several types of information in memory, and some information may
be stored in either RAM or ROM:
The operating system contains the instructions that make the Prophet VS run.
All of the operating system is in ROM.
Waveforms are the basic elements of each sound program. RAM can hold
32 waveforms, and ROM contains 96 waveforms. You select a RAM or ROM
