via this auction

"The Expander is a Rhodes Chroma in module format. Less than 200 Expanders were made.
This is #16.

It has been fully serviced and upgraded by Randel Osborne who has restored many Chromas and also builds the Enabler controller (video below). [posted here - V2.0 demo here]

- installation of the switching power supply (by Luca Sasdelli)
- installation of the CPU Plus (CC+) control board (MIDI upgrade with breakout cable)
- complete synth testing, adjustment, cleaning

Extreme rarity, top-level restoration and essential upgrades make this Expander a very special instrument and high-value investment. It’s the rarest version of ARP’s most powerful synth, in perfect working condition. Amazing by itself or paired with another Chroma."

Roland / Jupiter-6 - six-voice polysynth

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

via this auction

"The Roland Jupiter-6, although it was initially created as a more affordable alternative to the famous and beloved Jupiter-8, is a great six-voice polysynth in its own right, serving up iconic analog Roland sounds. Introduced in 1983, the 61-key Jupiter-6 added MIDI capabilities and improved upon the oscillator stability of the 8. Despite its heritage as a cheaper take on the 8, the Roland Jupiter-6 has become a classic synth in and of itself. Fully revised. Perfect state."

Roland Juno-60 Keyboard Synthesizer

"The only issues in functionality that I can perceive:

• Finicky 'key transpose' button - may need to be cleaned or replace

• 'Frequency' slider sticks toward top of slide. Still functions, but it may also need to be cleaned or replaced.

• It seems the previous owner saved a bunch of bad presets. I am able to edit each patch individually, but I can’t get it to save. According to what I've read online, the battery will most likely need to be replaced, which seems to be very common after 30+ years.

ARLPG Demo and tutorial

video upload by kNoB Technology

"This is an active resonant filter 12db\oct based on vactrols.
When creating it, I had a goal to make a compact and powerful tool for filtering signals.
First thing - I tried to keep the bouncy sound of great-grandfather in the face 292, the second thing is to add a completely new resonance circuit, also driven by vactrols, in which the resonance would have a large amplitude at medium and low frequencies and decrease towards high frequencies, in order to avoid the frequent case of uneven auditory perception of a high level of resonance.

The REG (regeneration) knob was also added, which gives additional functions, at the minimum value of this knob, the filter does not color the signal, and works like a VCA, as well as reducing the attenuation of vactrols, at intermediate values it reduces low frequencies in the resonance circuit and allows you to finetune both the character of the resonance and the sound of the filter.

The filter has two operating modes HP and LP. (HP mode 6db/oct)
