SN76489 MIDI

The SN76489 sound chip was used in the Sega Master System and Megadrive game platforms. I wired one to a Teensy microcontroller acting as a USB MIDI device. This is an early prototype. It currently uses one tone channel only but supports MIDI velocity, pitch bend and aftertouch messages.
The song you heard is "Taïkonaut's Love" from Yoann Turpin's "Rhythm'n Bits" album.

The song is beautiful. The PSG square sound plus some reverb, vibrato is also very nice.
Thanks

I love the square wave, it's beautiful :) Great playing too :)

[@aura-audio]

I love this! It's like a Gameboy synthesizer to improvise on. Perfect for a jam session or jazz band practice lol.

I got SN76489s on utsource.com along with some YM2612s and YM2149 :) Thanks for your comment. I'll definitely release specs and code when it's ready :)

A very capable sound chip. used in the BBC B Microcomputer (Acorn Proton)

I would love to do something like this....

[@MarkOfBitcoin]

Impressive!!

[@otakkusu2]

Bravo!

[@synthetic_paul]

Hello, I am looking at the specs and it says it has 16 volume levels... do you know how the chip handles this? Does it have an onboard DAC, or perhaps VCAs somewhere inside?

[@ClbnaVGM]

Awesome !!! Can you control the ADSR envellope of the psg ?

[@RobynTapps]

bro how did you get the matrix working?? having Bella troubles with it haha. and this is a fucking amazing project props!

[@williambelr]

Can you share the code and wiring diagram for this? Thanks!

[@entozoon]

What library did you use to read USB MIDI? I can't for the life of me find anything that does it, unless you're using a traditional MIDI input.. can't quite see

[@ma1e0]

As far as I can remember, it was the USB MIDI implementation from Teensyduino: www.pjrc.com/teensy/td_midi.html

[@DualityCovers]

Hey, i have the teensy 2.0 ++ and a electrical piano with midi output, how can i use to connect my piano to my pc using teensy for examplo to use garage band or something like that?

[@alexwong7367]

no information provided where to buy this unit?

[@ConnorR.mp3]

I've got to say, i hate this chip so much but this is pretty cool.

[@akrobate321]

Rhooooo!!!! C'est bon ca!!! Terrible!!!
