Midi ic?

Greetings,

Anyone know of an IC or module that can take MIDI events and produce audio? I guess I'm looking for the IC that lives in a billion cheap piano keyboards.

I would be feeding this from the propeller so UART would be the interface that I'd prefer.

Thanks,



Red

    See if the VS1053B does what you want. I have not looked at this in detail for midi or general midi output. I use it for MP3 decoding and playback from a USB drive and like it. T

    Have you tried the P8X32A!

    Yes, the VS1053 is one of the go-to chips for this. I use it a lot for MIDI. It's quite adaptable, and the serial-in protocol is MIDI standard, allowing you to use it with any MIDI controller -- or, of course, product your own controller using a Propeller or whatever.

    Unless you can easily work with surface mount you'll probably want a breakout board with the chip already on it. I keep trying to get Parallax interested in making one, but in the meantime, there's always SparkFun. Look at their Musical Instrument Shield. You can use it as a simple breakout if you don't have an Arduino. Connect 5V, ground, Rx, and Reset.

    There's also the Fluxamasynth, a shield using an Atmel MIDI synthesizer. It appears a bit more robust than the VS1053 in the effects department. This board is about $10 more than SparkFun's, though.

    Looks like the SAM2195 isn't Atmel anymore.
