Abstract

Ein elektronisches Tastenmusikinstrument wird durch einen Hauptsystem-Rechner in Abhängigkeit von Eingabe­ elementen gesteuert. Ein Stimmenmodul (VI) besitzt ein Untersystem (6) mit einem Untersystem-Bus (UB) und einem Speicher (URAM) und Mikroprozessor (UCPU) aufweisenden Untersystem-Rechner (UMC). Zum Datenaustausch zwi­ schen Haupt- und Untersystem ist ein Bus-Schalter (BS) vorgesehen, der den Untersystem-Speicher (URAM) ab­ wechselnd mit dem Hauptsystem-Bus (HB) und dem Unter­ system-Bus (UB) verbindet. Dies erlaubt einen "real time-" Datenaustausch zwischen Hauptsystem und Untersystem. An electronic keyboard musical instrument is made by a main system computer depending on input elements controlled. A voice module (VI) has one Subsystem (6) with one subsystem bus (UB) and one Memory (URAM) and microprocessor (UCPU) Subsystem computer (UMC). For data exchange between main and subsystem is a bus switch (BS) provided that the subsystem memory (URAM) alternating with the main system bus (HB) and the sub system bus (UB) connects. This allows a "real time" Data exchange between main system and subsystem.
