CS266490B1 - Code-controlled tone signal generator - Google Patents

Abstract

The tone signal generator, controlled by the code, includes a keyboard encoder 1, a group of n-1 outputs of which is connected to the first group of n-1 inputs, and a group of "m" outputs - to the first group of "m" inputs of the digital comparator 2, a PORTAMENTO generator 3, a reverse counter 4, a note divider 5, a high-frequency generator 6. The tone signal generator also includes a % octave divider, a power supply 8. A group of m control inputs is connected to a group of m inputs of the reverse counter £
