SINGING CHOIR OF 700 The Big Brain becomes a spectacular choir of 700 singing voices using this technique! Use the Brain's first two Propeller chip arrays of 100 chips loaded in parallel using the injectors and execute code simultaneously. Chip Gracey's code Singing Monk Squad of 7 is multiplied 100 times in parallel to create a singing choir of 700! Also pace the vocal squad dudes in the Singing Squad of 4 if you prefer a choir of 400. It's up to you to mix all those audio signals. Check the schematic for the Parallax Propeller Demo Board for running the audio connections. Propeller Demo Board Rev D/E/F Schematic
