Acorn Electron Music Studio 1-bit Beeper Engine Player

Music Studio

A classic ZX Spectrum beeper engine

This engine provides two melody channels, plus percussion that may take the place of individual melody notes on channel 2. Sustain settings are ignored, any percussion entered into the Drum column will cause no note to be sounded on channel 2 for the duration of the drum effect.

• Original version by Saša Pušica
• Atari 8-Bit GTIA/PIA port by Krzysztof "XXL" Dudek (https://forums.atariage.com/topic/200742-simplest-gtia-beeper-engine/)
