"The PolyPhonic SQ is a 64 button, wireless - Bluetooth, MIDI input device based on the Project 64 Button board hardware, an Arduino and a serial to MIDI software from SpikenzieLabs. It is fully PolyPhonic, any number of keys may be pressed at the same time and notes are sustained as long as the keys are pressed.

It uses a new version of the SpikenzieLabs Serial - MIDI Converter software which also allows you to select the baud rate of your serial port. (The new version will be available for download next week.)

Note:
1. Works equally well with a USB cable but the bluetooth is sort of fun."

The Stethosphone - Stethoscope Synthesis

"The Stethosphone is an "alternative" miking tool built using a couple of electret mic capsules mounted inside a cheap stethoscope. This instrument is very useful in order to experiment with surface recording from any object and it is good even as new way to record instruments such as guitars, drums and so on."

The Sosnowski Synthesizer

"The Sosnowski Synthesizer is an analog-style software music synthesizer. The download includes both a standalone player version and a VST version for use within suitable hosts. 128 onboard sounds are included, with additional sounds in external files. The instrument is specifically designed to be equally at home as both a "performance synth" and in studio audio, sequencer, and notation work environments.

With a simple, clear, easy-to-use and well-organized layout and sensible architecture, the Sosnowski Synthesizer is ideal for newcomers to the art; yet, with its rich feature set and thorough controllability, even seasoned professionals will find it an attractive and inexpensive addition to their resources.

The Sosnowski Synthesizer generates sound with four separate oscillators. Each individual oscillator includes selection for sine, triangle, sawtooth and square waveforms; plus a selection for a noise oscillator with its own adjustable frequency trap. The oscillator outputs are processed through a multiform filter with its own envelope and modified by dual independent multi-waveform, fully adjustable LFO's (low frequency oscillators).

A final envelope shapes the sound before proceeding to the sound treatment section. Onboard sound treatment includes stereo chorus, reverb, echo, pan/x (automated dual-constant cross-panning), and transposition; all of which are fully controllable from the interface.

Additional features include an onboard velocity-capable keyboard; MIDI channel, program change enable, volume enable, and pan enable switching; an onboard 'scope and parametric equalizer; and a capable preset manager for onboard sounds, plus an easy file system for saving and loading custom sounds."
