Drum kit, MIDI, Arduino
Drum Synth/Bass Synth by Glen Gutierrez are 2 programs featured in the Antic Feb. 1985 issue.  Antic Editor: "These are the most realistic instrument simulations we've ever heard at Antic."  The Drum Synth program has been MIDIfied to except data from an Arduino+MIDI shield through the joystick port.  Now the drums can be beat from a MIDI k...

A8 MIDI and the Atari Age of rediscovery

MIDI, MMS, MIDIMate, midimax
When I started the Computer Blues Project I really thought there was no way to program the MIDI MATE from BASIC and that using the RS232 port was an option.  If you don't have a MIDI Mate or MIDI Max, it is an option. If you do, there are ways of programing BASIC MIDI applications for them.   I am just now starting to discover those me...

The Voice Synthesizer - before I move on

Voice Synthesizer, RS232, DFROBOT
Getting the DFRobot voice synthesis shield working was an interim project until I could justify the procurement of a Wizztronics MidiMax unit.  Now that it is here I want to get the last experiments documented, in case I ever want to turn the shield into a MIDI device.
The last modification to the type and talk program added the ability t...

Type & Talk, just 3 lines of BASIC Code

Speech Synthesis, RS232, 850 and 1 more...
How many lines of Atari BASIC is required to make the Arduino shield from the last blog post talk?  3 lines - type some text, hit return, send text to the 850 interface and repeat.  The Arduino receives the text, does a little reformatting, then sends that string to the XFS5051CE chip for speech synthesis.  This isn't just for the Atar...

The $42+$10+$7 Voice Synthesizer Warning: This entry is about the hardware of an ongoing project. It may create more questions then answers.  Please post any answers, along with the question, in the comment section.
Be careful what you put on your Amazon Wish list. You just might get it. Before the holidays  I loaded mine up with Arduino shields,  breakout boards,...

How to play Star Raiders with a 3 year old

joystick mod
My wife tells me that our three year old granddaughter may be a little to young to enjoy a game of Star Raiders.  To which I said, "You may be right." And then I put the cartridge in.
I have to admit that the first try was not all that successful. I gave her the joystick and she found the fire button.  She just kept firing till she hit so...

SIO2MIDI - Home Made MIDI Interface.atr

Posted by Pack007, 04 November 2016 · 361 views

SIO2MIDI - Home Made MIDI Interface.atr A disk image with Chris Terpin's Home Made MIDI Interface(1991) had been downloaded at some point during the MIDI Blues project and was not examined until now.  The disk contained a text file giving a brief (and somewhat incomplete)  explanation of how to build the MIDI I/O circuits and hook it up to the SIO port.  That was Part 1 of 2,...

Tired of the Blues

Computer Blues, 850, MIDI, RAMO
Tired of the Blues How much can you change a program before it becomes a different program?  I believe I have reached that point with Computer Blues.  Version 4 got rid of the base repeats and Version 5 gave each voice its own channel and different patches for the JAM()  and base notes.  Fixing the timing can be done but would require a major rewrite....

Implementing the MIDI Implementation Chart

Posted by Pack007, 12 October 2016 · 240 views

Playing MIDI notes has turned out to be quite easy for Atari BASIC through the RS232-Arduino-MIDI OUT (RAMO) interface (see previous posts in this blog).  Most MIDI instruments have additional functions beyond  receiving the note ON and note OFF commands.   Each MIDI instrument should come with a MIDI Implementation Chart (MIDI-IC) tha...

A8 Wind Chimes - Gentle Breeze in C minor

MIDI, chimes, Arduino
There is a sound recording of the first attempt to simulate wind chimes within the following .ZIP file.  It was recorded using Window 10's Voice Recorder.  The A8 used Atari BASIC's RND(0) function to pick note, volume, and delay values for the chime strikes.  Then sent the MIDI data to the Yamaha TG33 Tone Generator, Preset 2 #87 PC*Bells....
