"A Nebulophone stylus synth and Pico Paso light controlled stepped tone synth, both are brand new and have never been used. Being sold as a pair. Full details of each below or at http://bleeplabs.com
Nebulophone
The Nebulophone is an Arduino based synth with a stylus keyboard.
- Eight waveforms
- Light controlled analog low-pass filter with five adjustable LFO LED modes.
- Perfect tuning across six octaves.
- Adjustable temperament and key.
- HYPERNOISE 30XX mode.
- Six arpeggio modes with adjustable rate.
- Programmable sequencer to easily make your own arpeggios right on the Nebulophone.
- Adjustable portamento.
- Infrared communications allows multiple Nebulophones to easily communicate. More about IR-sync.
- Open-source Arduino code and hardware
How do you listen to it?
The Nebulophone has a 1/4″ mono output designed to be plugged it into any mixer, amp, USB interface, etc. Headphones will work but are not recommended.
Are the keys touch sensitive?
The alligator clip must be used to trigger the keys. You can also wire the key pads to switches as some makers have done.
Pico Paso
The Pico Paso is an analog, light controlled, stepped tone noise synthesizer designed by Dr. Bleep.
It’s based on the concept of the Atari Punk synth, aka Forrest Mims’ stepped tone generator, but uses two triangle wave oscillators that can be combined or used separately. A wave shaper and square wave LFO are used to increase the aural ridiculousness.

What are the SQU1 and 2 pads between the buttons for?
These are the square wave outputs of the main oscillators, allowing makers to use these signals along with the triangle waves. See the schematics for more info."
"This is a Roland JD-800 in nice, clean condition. Sounds fantastic & plays great. Perfect working order & no issues. Cosmetically: less than normal wear & light scratches on left end cheek, right front cheek, back edge, & bottom of synth. I consider it to be minimal & actually hard to find (please see photo's.) Included are Roland Brass Section data & waveform cards & the original AC cable."

"Sequential Circuits Prophet 5 original vintage analog polyphonic synthesizer. This is a Revision 2 board that has been upgraded to Revision 3 specifications, including MIDI added and memory banks upgraded to the full 128 offered in later revisions. 
"For sale is a hand built, perfect circuit clone of the infamous ARP2600. The synth was professionally built by an electronics technician, with 15 years of experience in synthesizer repair. This synth was built with all of the rare, originally used electronic parts. Additionally, built into the case is a new spring reverb, built with the same specs and by the same company that provided the original reverb units for the ARP2600. There are two modifications that have been added to improve on the original designs. There are 3 separate VCO sub-regulator boards which further regulate the power delivered to the VCO’s; this corrects an original design flaw in the ARP2600 by providing added pitch stabilization. Also added is a gate/trigger booster so it can be used with modern synths, such as Eurorack modular, Arturia Mini/Microbrutes, Arturia Beatstep, etc. The gate/trigger booster has been normalized to the traditional input jacks such that when unplugged it uses the traditional ARP +15v triggers, when plugged in it can accept any trigger from +3v and up; thus making it compatible with virtually anything that outputs gate/cv. The case was professionally built by a kitchen cabinet company and is solid maple, stained black.
"It is in good functional condition with the exception of preset button 7 which is broken and cannot store presets. The previous owner replaced the original battery so there are none of the usual problems with battery leakage. Motherboard was also replaced, with many new and old capacitors, resistors, etc. Beautiful cosmetic condition with very few marks, just a small chip in the wood panel on the right side which is pictured."
