"A pre-owned Sequentix Cirklon & CV Breakout in very good condition. It comes with the expander cable, power supply and original manual.
Manufacturer's description
The Cirklon Mk1 is a dedicated hardware sequencing workstation designed for precise, real-time control of MIDI, USB-MIDI, and analogue systems. Built around a high-resolution encoder interface and a structured pattern engine, the Mk1 provides tight timing, flexible routing, and a streamlined workflow for complex setups.
This unit ships with the CVIO breakout expander, offering sixteen analogue control voltage outputs and eight gate outputs for direct integration with modular and other voltage-controlled instruments. The CVIO system delivers calibrated, low-latency analogue control suitable for demanding studio environments."

Additional Tone Tweakers Listings
"We fully disassembled, cleaned and serviced this unit the way we typically do with our high end vintage synths, in an effort to make it as good as it can be. This restoration took 12 hours of highly skilled vintage synth tech time, plus parts costs. The high value of this work is of course factored into its price that should be considerably higher than that of cranky unserviced or minimally serviced examples on the market."

via this eBay listing
You can find demos in previous posts here.
"This is the Shard harsh noise generator — a boutique power-electronics / industrial sound device known for its aggressive textures, chaotic oscillators, and fully manual performance controls.
A favorite among harsh noise, PE, drone, and experimental sound artists, Shard units are highly sought after due to their unusual interface and raw sonic power.
The panel includes multiple oscillators, pitch controls, gates, chaos switches, atrophy charge pads, and external input options for expanding or processing noise in real time. Great for standalone improvisation, modular interaction, or adding harsh layers to audio work.
⸻
Features:
• Multiple oscillators with individual pitch controls
• Patchable ports for expanded routing
• Dedicated chaos & atrophy switches
• Gate pads for manual noise triggering
• External input for additional audio processing
• Rugged metal enclosure
• Runs on 9V power (battery or adapter)
• Perfect for harsh noise, PE, dark ambient, and experimental sound design"

Make Noise Almost ReSynthesizer // Diffusion Patch
video upload by Dexba
"[no talking, patch notes on screen]
I am building a ReSynthesizer, little by little, and I wanted to share with you my journey while the case is not yet full, but already showing a lot of potential for interesting patches.
This is how I envision a patch I would go live with: some key points ready to be messed with, but without the need for planned sequences, saved patches, and so on.
I hope you will enjoy it as much as I did playing it 🧡"

Using a foot pedal with GLOOP
video upload by Cutlasses
"Did you know you can trigger start/stop of the recording on GLOOP with a foot pedal, which is perfect if you're playing guitar and want to be able to record hands-free. Here I'm using the ADDAC Gate Pedal, but any pedal that produces a trigger voltage greater than 3V should work. Alternatively you can use a pedal conversion module. We still have some GLOOPs available in our store, https://www.cutlasses.co.uk/"
