"In this video the Altair 8800 is used as a generator and controller.
The RAM is dumped out to the serial port with the aid of an assembly (player) program loaded into pROM.
The data comes out at 9600 Baud N81and it is interpreted by 8 oscillators that set their frequency accordingly.
The sense switches OR the data so note can be shifted and set at different intervals.
Sound programming on MaxMSP, Altair Programming with WS editor and ASM assembler.

The data in RAM can be recorded using an handy converter for Max, let be degraded by turning off/on the computer, or play back the true random junk that pop ups in RAM whenever the Altair is turned on.

Interesting whole tone nuances in some points."

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

How I did it - Episode 2 - Altair 8800 as a drum machine from Giorgio Sancristoforo on Vimeo.

"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!

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!

Altair Sequencer Project - How I did it - #00 hello world

How I did it - #00 hello world from Giorgio Sancristoforo on Vimeo.

"The altair says hello to Max!

The idea is simple: to make music with the Altair 8800
The first commercial Personal Computer made in 1975.
In the following episodes I will
• Interface the Altair with MaxMSP via serial port
- programming a drum machine in assembly
- program a generative orchestra in assembly and or MBASIC
- Explore OSC routing to other software (Processing), upd comms.
• Interface the Altair with an analog synthesizer: a Buchla Music Easel by using arduino and a breadboard.
The quest for controlling Max will be the first step, later I will dedicate the project to analog synths.
I'm going to post every episode here and on my website (giorgiosancristoforo.net)
I will explain every single byte and strategy of programming and share the Max patches for Windows and Mac OS.
so that 8080 enthusiasts could replicate the whole process.
It will be also a nice opportunity for electronic musicians to understand simple and fun microprocessors' programming techniques.
Any help, comments and critics from retrocomputing and assembly lovers, is more than welcome.

Building a Sequencer with the World's First Personal Computer

Giorgio Sancristoforo is the man behind Berna.

"So here is the idea: in the video episodes that I will post here, I will learn assembly, refresh my Basic knowledge, and start programming and connecting the Altair to a modern PC/Mac to transform the Altair into a digital sequencer (linear and/or generative).

The first part of this musical quest is to make the Altair communicate with MaxMSP software by Cycling74, so I will be able to build both standalone programs and MIDI software interfaces, later I will try to make some tests with Processing.

Next I’d like to interface the Altair with Arduino and see if I can manage to work to a prototype board+software to sequence Control Voltages for the Buchla Music Easel analog synthesizer. The Easel’s programming cards are the ideal interface for the task. Any help, comments and critics from retrocomputing and assembly lovers, is more than welcome."
