J.S. Bach C Major Prelude & Fugue, Book 1, BWV 846

YouTube via AaronAndrewHunt

"Here's a rendition of Bach's C Major Prelude and Fugue (opening) played in Just Intonation on a Tonal Plexus keyboard. Obviously, Bach did not write this music to be played in Just Intonation (the "Well Tempered" part of "Well Tempered Klavier" has a specific meaning for tuning), so this is an experimental performance which uses pure 3rds and 5ths, natural 7ths in dominant chords, and harmonics reaching the 17-Limit in diminished chords. In several places, a common tone can be heard to 'bend' from one chord to the next (usually in ii-V progressions) where a pitch has to move by a septimal comma; the pitch is changing in real time by JND steps. This is a single take. I played only the opening of the fugue, very slowly ; ) This is for two reasons. First, so my fingers will behave and play the right keys, and second, so the sounds of Just Intonation can be savored a bit. Find out more about the Tonal Plexus at http://www.h-pi.com"

Siel Expander 80 Analog Synthesizer With Mods

via this auction

"A Siel Expander 80 with added Mods: 4 knobs and theremin [light sensor] control.

The Siel Expander 80 is an analog polyphonic synthesizer from the 80's. Back when controlling parameters with a push button interface was a must. Nowadays the analog sound with analog style control (knobs) is very much sought after and desired. This expander is modded so it now offers 4 parameters to be controled hands on by 4 knobs and a LDR resistor (theremin like control). The original power supply is included with this synthesizer!

The knobs from top to bottom:
Cutoff - edit the cutoff frequency in the menu and turn this knob to have hands on control of a portion of the total cutoff frequency spectrum this synth offers.
Resonance - set the resonance level to max and control the whole range of the available resonance levels with this knob.
vcf envelope level/pitch - this knob controls the level of the envelope. Turning it will also cause to lower or increase the pitch a few tones.
Distortion/chorus - give the synth a bit of lowfi distortion with this knob in left setting. Turning it right will give you control over the synth's chorus level: fattening its sound.

The LDR:
Waving your hand above this sensor will modulate the cutoff frequency! You can set the level of modulation with the cutoff knob. The theremin function can be turned on or off with the red switch on the left side. Using the theremin function will disable the cutoff knob.

Cool thing about the Expander 80 is that every parameter can be controlled by MIDI CC messages. So hook it up to your favorite (pc) sequencer and/or control if with your midi controller!
