ARP 2500 Bible - Matrix Switch Patching
video upload by O.Z. Hall
"This video explores the Cherry Matrix Switch patching system used by the ARP 2500 modular synthesizer. We're demonstrating in detail the possible uses of a matrix switching system using a one-of-a-kind Cherry Matrix Switch 10x10 module. We're patching a system made up of the Behringer ARP 2500 modules.
Check it out!"

This Is A Test - The Wizard's Hand prototype - ambient energy to cv translator
video upload by Mountainking Electronics
"The Wizard's Hand is part of a group of designs called bio-intergration interface devices. These devices have come about as a result of my ongoing search for not only new ways of using our physical bodies to control and effect electronic musical instruments but also finding ways to tap into and use the ambient energy fields that surround our bodies to influence these instruments.
The Wizard's Hand works by sensing the effects our bodies have on the surrounding electrical and electro-magnetic energy fields and translating those effects into a varying control voltage. It is an organic device who's sensitivity and effects can change from day today, place to place, person to person, etc, etc. The user needs to learn to "feel" the energy fields surrounding the Wizard's Hand through the use of intuition to "lock in" on these subtle energies and gain better manipulative powers over them.
In the video the Wizard's Hand is plugged into the pitch cv input on a VCO. There is a toggle switch that switches the signal at the OUTPUT jack from the Wizard's Hand circuit to the EXT IN jack. With nothing plugged into the EXT IN jack moving the switch to the EXT position allows you to instantly disconnect the Wizard's Hand from whatever you have it interfaced to. This is demonstrated in the very beginning of the video. The Wizard's Hand has two knobs, one called SLEW, this adjust a "glide" or "portamento" type circuit which the control voltage that comes from the Wizard's Hand is sent through. There is also an OUTPUT knob, this allows you to attenuate the CV signal that is available at the OUTPUT jack when the accompanying toggle switch is in the W.H. position. There is also a toggle switch that allows you to limit the maximum cv level to 5v dc. Lastly, there is aƬ toggle switch that allows you to switch between the Wizard's Hand putting out a varying control voltage or an on/off gate signal.
The Wizard's Hand is an experimental device and as such will require more testing before the circuit is finalized.

"KSR have carried out a service on this Xpander in February 2023.
Remarks: Much has been written on these incredible synthesizers and it's understandable when you use them as they really can deliver a thick analogue wall of sound, and are perfect pad and brass sources just for starters.
The Xpander lineage includes the Matrix 6 and 12 and is a fully midi configured, 6 voice Polysynth - an excellent addition to any analogue set-up and has to be heard to be believed. he Xpander offers a deep programmable architecture for those of you into tweaking but can also be a very user-friendly hands-on preset machine. This means they sit between that digital and analogue medium perfectly and are arguably the best of the hybrid technology of the early to mid-1980s.
This example is a USA built unit that works perfectly, and as mentioned above, has just been fully serviced by KSR. The cosmetic condition is excellent, as you can see from the pictures below, with only minimal wear and marks to the painted surfaces."

"A beautiful condition Roland Jupiter 8 (12bit model) - Serial Number: 161512, which has been retrofitted with a Groove MIDI kit.
We are always very happy to sell any Jupiter 8 and this one is an excellent representative example that has MIDI as well. What can we say that hasn’t already been written about the JP8…honestly, nothing new. However, we’ve seen relative values for this flagship vintage analogy poly-synth climb sharply in recent years, so they’ve become unaffordable to most people, which is a real shame.
The overall condition is excellent, with far less than he normal amount of wear we would expect to see on a synth this age, so this example has been very well cared for throughout its existence. The photos below tell the story, but even the base of this JP8 is in great shape."
