"The last version of my VS1103b MIDI synthesizer. I have designed nice front and back panels which are made of laser-cut plastic. I have also gotten rid of the noisy volume control and the MIDI thru, instead adding separate left and right audio outputs. Schematics, stripboard layout, more photos and a full writeup can be found at : http://www.instructables.com/id/E82VEK1GXUZ7YJA/"
Follow-up to this post.
It is this MIDI synthesizer capability that we are interested in. Make no mistake - the quality of the MIDI voices isn't stunning, but it has a charm to it that reminds me of the FM synthesis found on old Soundblaster cards of yesteryear. The VS1103b MIDI synthesizer mode conforms to the General MIDI standard - 15 melodic channels and 1 percussion channel.
The only problem with this chip however is that it is a very small 48 pin surface-mount package. Fortunately, SparkFun make a break-out board for this chip that has a 20 pin DIP package - much more suitable for DIY electronics."
