Elektron Monomachine Keyboard SFX6 - 1 of 500 with Original Box

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"From Elektron's website:

Once upon a time there was a synthesizer called the Monomachine SFX-6. It existed for four years and only 500 units were made. Today it is considered somewhat of a rarity. It was actually the first version of the Monomachine as the keyboardless tabletop variant was introduced a few months later. A lot of attention was drawn to the looks of the SFX-6. In contrast to more common synthesizer designs, the keyboard and the control area of the SFX-6 were separated in two distinct sections. The intention was to allow two musicians to jam together using a single synthesizer. One of them would be in charge of the keyboard while the other one operated the sequencer and adjusted sound parameters. Getting hold of a Monomachine SFX-6 today can be hard, but there's no reason to despair. A MIDI keyboard connected to the SFX-60+ MKII will provide more or less the exact same functionality."

ARP Odyssey MkIII - Lumina Upgrade, Dual VCF (4023/4035), LFO Aftertouch

Note: Auction links are affiliate links for which the site may be compensated.

via this auction - learn how to sell on eBay here

"It's recently been upgraded with the CMS Lumina slider kit (beautiful silky smooth action - all high quality Bourns PTL45 series LED Sliders). The LFO slider LED lights up as a visual indicator to the frequency, and the AR/ADSR slider LED's glow according to what the output voltage is.

It's also been retro fitted with aftertouch for LFO control of VCOs 1 & 2, and most intriguingly, a dual switchable VCF!

The original 4075 VCF module has been replaced with the 40235 Dual Filter (Google it) which consists of the MkI "White Face" Odyssey 12dB VCF and the MkII "Moog Infringement" 24dB VCF - the switch on the right hand side of the keyboard allows you to select between them.

The Keyboard bushings have also been replaced, as have the leather side panels. The main audio outputs have been swapped... the high level output is now on the jack socket and the low level out on the XLR.

I've never been happy with the gold "J-Wire" contacts under the keybed, and at some point they will need to be realigned/replaced (it was next on my "to do" list) - occasionally, when playing duophonically, the upper voice output to VCO 2 will glitch, but this is a common problem with the MKII & III Odysseys..."

"This is no desktop app crammed onto a touchscreen. It seems the interface has been designed around your fingertips." Peter Kirn from CDM (createdigitalmusic.com)

This multi-touch enabled app makes it simple to invent unique loops and musical phrases. Manipulate the sound of the synthesizers by tweaking the oscillators, resonant filters and audio envelopes. Add audio effects like reverb, distortion, phaser, filter and delay to your sounds.

Appropriate both for experienced musicians and beginners.

Roland Jupiter-8 With NEA Pyxis Aftertouch System

Published on Sep 17, 2013 New England Analog LLC·27 videos

"This video shows a Roland Jupiter 8 with the New England Analog Pyxis aftertouch system. The purpose of this particular video is to show how you can disable the lower 4 voices on the JP8 so that aftertouch wont affect them. However, using the aftertouch sensor on the lower half of the keyboard can still affect how the aftertouch modulates the upper 4 voices. This creates some interesting effects. Using "whole" mode with the lower 4 voices disabled will produce a sound much like a CS80 or something with polyphonic aftertouch. On this particular Jupiter, there are two separate disable switches; one for disabling filter and VCA effects from Pyxis on lower 4 voices, and another for disabling Pyxis control of VCOs."
