Sound + Speech Chips/Amps - Arcade Chips. ChipKIT Sketch: Mini Polyphonic Sampling Synth. Music Instrument Shield. Description: Do you ever wish your Arduino was more musically talented?
Or maybe your project could use some cool sound effects. The SparkFun Musical Instrument Shield is an easy way to add great sounding MIDI sound to your next Arduino project. This board is built around the VS1053 MP3 and MIDI codec IC, wired in MIDI mode. Simply connect a speaker/stereo/pair of headphones to the 1/8" stereo jack on the shied and pass the proper serial commands to the IC and you’ll be playing music in no time! The VS1053 contains two large tonebanks including various piano, woodwinds, brass, synth, SFX and percussion sounds. In this version, we’re using a better regulator, corrected the speaker connectors, and have the reset pin pulled high. Documents: VS1103b MIDI Synthesizer. I published a guide on this a while back, but it was disorganized and scruffy, so here is a tip-top new version with proper photos, diagrams, and a full write-up. The VS1103b, manufactured by VSLI Technology, is a single-chip MIDI/ADPCM/WAV audio decoder and ADPCM encoder that can handle upto three simultaneous audio streams.
It can also act as a MIDI synthesizer. 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. MIDIvampire-II. A vampirically powered drum machine!
The MIDIvampire-II is a 4 voice drum machine that is powered from the MIDI data line. It has 2 wavetable voices for making kick drums, toms, wood blocks, bells, and a host of other sounds. There is a voice set aside for hi-hats and cymbals, and another which is a filtered noise source, which can make snares and hollow-tube sounds.
Each voice has separate attack, decay, and release, along with frequency sweep, and a bunch of other effects for warping the sounds to fit all your percussive needs. And, there are independent outputs for each voice. All of the documentation, including the MIDI implementation is up on the MIDIvamp Wiki. 255-Voice PCM Sound Generator. Part 1. Schematic Audio Games Microcontrollers. This is a simple sound generator based on 8-pin SD Audio Player.
It is built with an Atmel ATtiny861 microcontroller from Atmel and an SD memory card. The tiny861 has fast PWM outpus like tiny85 so that it can generate clear sound compared to any other AVR chips. On 20-pin device, many GPIO pins are available. It enables to control the sound generator by external signals. Because it can be controlled with ease, this project is usable as sound module for toys, tone ringers, amusement machines and gadgets. Hardware A MicroSD card is used as storage media and also SD and MMC can be used with proper socket conversion.

While looking around for a synth chip to provide a default output for my stradella chord machine, the VS1103b offering from VLSI looked very promising.
This is the MIDI/ADPCM version of their popular low-power DSP engines that are used in mp3 players and the like. I wanted a quick way of hooking this up for a try-out without straining my eyes (and my patience) on the development of a suitable PCB to house the SMD package, and came across a break-out board (BOB) from sparkfun which might do the trick. I ordered one of these from Technobots and whilst waiting for it to arrive, I downloaded the schematic and the VS1103 datasheet, and read the latter thoroughly. I then had a scratch around on VLSI’s website for any other relevant information.
Reading the VS1103b datasheet, I inferred that there was a ’simple’ setup that did not require the use of a micro-controller, and indeed this is so.
