Altair Sequencer Project - How I did it - Episode 1

How I did it - Episode 1 from Giorgio Sancristoforo on Vimeo.

"The day has finally come! The first episode is here!

In this video I will demonstrate how to turn the Altair 8800 into a digital sequencer (it could do MIDI out with a few more code inside Max). The Altair communicates with my Mac with a Serial to USB adapter. All the Altair code was written under CP/M 2.2 using Word Master word processor, ASM Assembler and Load program.

The code basically outputs 8 notes and a rhythm pattern. All the notes are in MIDI note number values (see for example line 0113h. The rhythm pattern is a 1byte binary number that works as a gate for the steps of the sequence.

In the next episode I will develop the concept further and get some polyphony.
As soon as the max patch will satisfies me, I will publish here the patch and the code to make music with your Altair, clones and originals.

Any question, comments and critics may be addressed to me by sending a mail (see contacts page on my website) or commenting the vimeo video here:) .
Thanks for watching and see you on the next episode!
