"Moffenzeef Stargazer, a monster of a self contained synth that… well if you’re reading this you get it. Scare the hell out of your neighbors or destroy the sound system at a local club,. This thing is not for the faint of heart, a sci-fi soundtrack in a box! This is from the limited run of 75 In red a few years ago but as you can see in extremely good condition with all original packing and swag."

Moffenzeef Modular Stargazer Limited Run of 75 - Red
Yamaha DD-14 w/ 25 Point Patch Bay Mod
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"Rare 1993 MIDI drum machine with a custom 25 point patch bay. This modification generates an array of original sounds, effects and rhythmic variations. Making a single connection on the patch matrix can dramatically alter the output but applying multiple connections produces an increasingly complex, sometimes aleatoric range of fractured, reversed, tonal, bit crushed, flanged, distorted, aliasing and delayed effects, 16-bit arcade sounds and digital noise, alternative rhythmic patterns and additional accents. The five included patch cables can also be stacked for further sonic manipulation.
The patch bay affects the 100 tempo adjustable onboard rhythms and tracks in addition to the pads and scraper which produce some great degraded digital effects and percussion hits.
Features:
8 velocity sensitive drum pads.
A 'scraper' ribbon controller for the performance of preset instruments, scratching and rolls.
100 preset rhythms with instrumental accompaniment options.
75 PCM percussion and effects sounds.
30 percussion sets.
Selectable roll, flam and echo effects.
Auto bass/ chord function.
Three user song memory.
608 mm x 281 mm x 105 mm."

"Klassic Keys quick demo of our 1984 Oberheim OB-8"
via this auction
"Does it get any better than this? An immaculate example of an original analogue Oberheim OB-8, looking like its just emerged from the small LA factory in 1984 39 years ago. No mods. No hatchet repairs etc, with MIDI, new Fatar keys and (copy) owner's manual. Arrived from Switzerland March 2023, double-checked/serviced/calibrated by our TOP OB specialist...now back with us in the E.Midlands. There are now some wicked sounds on board.... be warned, this synth sounds staggeringly good..."

Two channel CV Gate Attenuator for 3.3V/5V logic with an arrow indicator or voltmeter
video upload by DeftAudio
"An overview of the CV/Gate attenuator with various options. Available here: https://www.tindie.com/products/defta..."
"Deftaudio Two Channel CV Gate Attenuator for Eurorack
Two channel gain and max voltage passive attenuator with three options available:
Basic version, two channel with 3.3V, 5V limits, precise adjustment and LED controlIndicator version, two channel with 3.3V, 5V limits, precise adjustment with a vintage arrow indicator per channel
Voltmeter version, two channel with 3.3V, 5V limits, precise adjustment with a single digital LED voltmeter
Description:
This is simple and efficient board to adjust voltage level when interfacing between Eurorack gear and to the outside world. It's specifically important for Gate levels, which exceed typical voltage level of 3.3V or 5V and go all the way up to 12V. While modular gear typically designed to handle those voltages, other instruments such as sync or arp inputs on vintage synths may not have a protection at all.
This board designed in mind with three modes of operation which are not available in other products:
3.3V logic limit. This mode is protected by a Zener diode and meant for interfacing to 3.3 logic gear, such as microcontrollers, Arduino, Teensy, etc.
5V logic limit. This mode similarly has a Zener diode circuit for 5V logic of the majority synthesizers sync, arpeggiator and other various trigger inputs.
Attenuation. In this mode multi-turn potentiometer sets the attenuation ratio. While two other modes set the max voltage limit, in this mode the output voltage is linearly scaled down to the attenuation ratio set.
Purchasing options:
PCB only: Only PCB board is included, other parts, such as connectors, diodes, resistors and LEDs are sourced by a buyer.
DIY Kit: Comes with all parts including arrow indicators or digital voltmeter per selected option. Soldering is required.
Assembled board: this option is NOT planned at the moment."
