This is a lo-fi synthesizer that is played by bridging a connection between the two large contact handles. The pitch is controlled by the amount of resistance. The more resistance or lighter touch produces lower frequencies. This oscillator is then modulated by a LFO, giving this device very nice throaty, almost vocal sounds. It can also be played through multiple people creating a human chain.
The three large knobs control the speed of the LFO, a low-pass filter, and volume. It is powered by an included 9volt battery. A green LED indicator flashes in sync with the modulation. A standard 1/4" output makes it perfect to connect to amps, effects, or recording equipment.
This is the second of a matched pair of these I built using repurposed cigar boxes, salvaged handles, and new as well as salvaged components. ... https://www.youtube.com/watch?v=leVtU_o-rRw

8-Bit synthesizer with 9 modes.
Video with example of syncing...
http://www.youtube.com/watch?v=EILFyszSyHk
You have control over the speed and pitch with 8 selectable modes, paged through with a single button.
Mode 1 - Pitch is tuned to 3 octaves of chromatic scale with LFO stutter effect.
Mode 2 - Pitch is tuned to 5 octaves of D Major pentatonic scale with LFO stutter effect.
Mode 3 - Run of frequencies down.
Mode 4 - Run of frequencies up.
Mode 5 - Run up and down.
Mode 6 - Frequency with modulation.
Mode 7 - Overlapping modulation.
Mode 8 - 4 simple rhythmic loops mapped over pitch knob, with speed control.
Mode 9 - Noise produced by random frequency. Pitch sets the max freq.
You also have a low-pass filter, volume control, toggle on/off switch, and a red LED light flashes in sync with the effect. It is powered by an included 9volt battery or any 9volt center-negative DC adapter. Output via a 1/4" jack that is easily connected to amps, effects or recording equipment. There is also a sync output over 1/8" jack. This works with the Auto-Step Synthesizer, Four Step Sequencer or any device that makes use of 5volt clock in.

This contains four square-wave oscillators that are triggered in a four step sequence.
You have control over the speed of the sequencer as well as the pitch of each step. There is also a built in low-pass filter and volume control. With the LPF rolled down you can raise the pitch of an individual step out of range, essentially turning off that step.
This syncs up with other devices that make use of 5volt clock. Over 1/8" (3.5mm) jacks it has a sync input and two sync outputs, one that outputs clock for each step and one that outputs clock per full sequence. This allows multiple units to sync up either step for step or over lapping. An example of syncing is at 1:52.
It is housed in an extremely tough, raw aluminum case. It is powered by an 9volt battery or 9volt center-negative DC adapter. It has a standard 1/4" jack.

Watch this Pilesar clip with this as part of their rig...

This is a lo-fi square-wave synthesizer built into a Guitar Hero guitar controller. The five fret keys are monophonic and sound the highest key being held down, this acts much like a guitar string when you hit the strummer switch. There are two modes, up for lower pitch and down for higher pitch. This does not play traditionally tuned notes and a pitch control knob acts as a way to tune the range of frequencies laid out across the five keys.
The whammy bar is used for pitch bending. There is a also a LFO modulation effect with controls for speed and intensity. Pitch can also be bent with external light sources via the selectable sensor in the neck. This does not hinder being able to remove the neck for transportation.
The three switches on the side control power, LFO effect and a permanant hold down on the strummer so you free up a hand to finger tap or tweak controls simultaneously. There is a volume trim control. The original led lights indicate power. It is powered by 2 AA batteries that are accessed behind the original battery compartment. Output via standard 1/4" jack.
Jason Mullinax of Pilesar now has this as a part of his rig.
