This is a working demonstration of a new feature that will be included in the next A26F update. Channel 1 of the Atari 2600 sound chip is used purely as a DAC for an input audio signal channel 2 is used as per normal (as a limited oscillator).The drums, pitch shifted voice samples and droning lead synths are all external audio which are fed to the Atari 2600 and played back on channel 1 in real time. The arpeggio and noise sounds are coming from the channel 2 oscillator.Note that all audio that is heard in this video is directly from the Atari 2600!This feature will be included in the next A26F firmware update.
