Classic Roland JD-800

via this auction

See the seller's other items for more.

"These keyboards have excellent sound capabilities and are used by many pro's including Jean Michael Jarre among others. Almost all JD-800's had a problem with the keybed. Excess glue eventually leaks into the keyboard action causing stuck keys, dead notes, etc. I had the keybed replaced last year during the Roland warranty recall campaign."

Anyone else hear of this?

Roland Jupiter 6 Synthesizer

via this auction

"This is unmodded, so the MIDI is original non-multichannel MIDI. It will send and receive on all channels, so you'll want to give it its own dedicated in/out from your MIDI rig if you use one.

The back panel has MIDI Thru/Out/In, Memory Protect switch (keeps you from accidentally overwriting your user presets), Tape storage Load/Save patches, Arpeggio Clock In, Patch Shift, Pedal Hold (that's where a Sustain pedal goes), VCA and VCF, Headphone output, line output, output level controls (High/Medium/Low) and an XLR out. This is the version of the Jupiter 6 with metal sides, not woodgrain."

Circuit Bent Modified Speak & Spell Math

via this auction

"Here we have a Benstruments, circuit bent Texas Instruments Speak & Math. Just like the Speak and Spell, exact same voice only the Speak and Math has better beat looping in my opinion. Works as a normal Speak until you flip a glitch switch.

Ive added these new controls: Opto-Theremin Pitch Control with on/off switch Pitch control knob that slows it to 8 bit sputtering and super fast high chattering. Tone oscillator button that creates a tone you can then manipulate with the pitch controls like a theremin 1/4" output jack that shuts off the onboard speaker when you plug into an amp or pa system Strobing blue LED for effect Active matrix glitch switch that causes glitching with each push of the membrane Loop switch with on/off and advance button for cool beat loops Reset switch to get it back to normal Glitch forever switch that sets the speak into constant gibbering of incoherent sentences Dual voice glitch switch that causes it to speak in both a high pitch and low pitch at the same time Ive added all the coolest mods you can find on these sweet robotic bent synthesizers. I guarantee all of my bentstruments for as long as you own, my work is solid and ive modified hundreds of toys and synths that are employed the world over by both famous and amateur musicians. Great piece to bring some creativity to your work."
