How I did it – Episode 2 – Altair 8800 as a drum machine

February 28, 2015 · Posted in Uncategorized 

Today’s show is all about drums!
The Altair8800 now works as a 8 steps drum machine, with 8 voices!

The sense switches are used as channels’ ON/OFF and each one of the 8 steps programmed in the sequence outputs a byte (used as a binary number instead of a MIDI note number) which I’ve used inside max to trigger all the drum kit samples. As usual the interface is programmed in MaxMSP and it communicates with the Altair with a serial to usb connection.

Easy and way funny!!

see you in the next episode, and may the assembly be with you!
