You can find demos and pics of the Percussion King in previous posts here.
"FACTORY SEALED- NEVER OPENED - YOU DON’T SEE THIS OFTEN - VERY RARE & HTF
PLEASE ONLY SERIOUS BIDDERS
1966 Vox Percussion King V829 Analog Drum Machine Factory Sealed In Box RARE. Box has a few spots where there’s small tears or openings as shown in photos. Bottom of box is last photo listed. Still has original identification tag on one side of the box.
The story behind this is in the late 90’s my Dad and a friend of his went up to Chicago from Texas to meet with an old music store owner who had lots of his old vintage inventory from the 60’s to the 80’s and was selling everything he had. My Dad was the first outsider to pick through the new old stock.
He came home with 7 of these percussion kings sealed in the box. Over the years he would occasionally sell one. And this is the last one we have.
This is an amazing item for vintage VOX collectors, don’t let this one pass you by. See photos email with questions. Buyer must pay within 3 days of auctions end."

Exploring the Hexinverter / Erica Synths Mindphaser | Drone Sound Study
video upload by synthetic theory
"Yesterday was Drone Day and technically I'm one day late, because I didn't finish the post-processing in time. But anyway: this felt like the right moment to share something a little different.
I'm currently expanding my rack and learning how to operate a few new modules properly. One of them is the Hexinverter / Erica Synths Mindphaser. At first, I honestly wasn't completely convinced. I tried it, struggled to find the right tones, packed it back into the box and was already planning to send it back.
But then I gave it one more evening.
Instead of judging it too quickly, I tried to understand how it actually works. I slowed down, explored the interaction between the oscillators, the modulation paths, the waveshaping, and the strange areas between tone and chaos. And then the potential suddenly became clear.
Some modules simply need more attention. They have a learning curve and they don't always reveal themselves immediately. But once you reach that point of understanding, they can turn out to be real powerhouses.
So this is not one of my usual performance videos. It's more of a slow exploration: a drone-focused sound study with the Mindphaser at the center, sometimes shaped by effects, filtering, gates, and modulation.

Math with The 257t
video upload by Stazma
"Today is Math 102 with the 257t.
Watch this if you use modules that output 0-5v and you want them to go to 10v, turn bipolar signals into unipolar ones, or if you want to learn some creative ways to mix them together to create more complex modulations.
A bunch of usefull tricks in there ;-)"

Chompi + Chase Bliss Onward | A Spontaneous Ambient Sketch
video upload by The Pedalboard Orchestra
"While testing my new KMA Audio Machines headphone amplifier, I stumbled upon this little musical moment.
Chompi Club runs a simple sequence into the Chase Bliss Onward, then through a parallel reverb setup with the EarthQuaker Devices Afterneath and Chase Bliss Dark World.
My wife heard it and suggested I record it before it disappeared, so this is a completely spontaneous one-take recording captured with a Zoom recorder while I was simultaneously holding a phone camera and playing the instruments.
Sometimes the unplanned moments are worth keeping."

Photokarpy#3 - Arpeggios on SIX (5) Korg ARP Odysseys
video upload by Richard Payne
"Just a quick Sunday Afternoon test of my ARP Odysseys. The free-running LFO mods I did are just the ticket here but a couple definitely need their Oscillators calibrating. I'm especially looking at you #1! A job for this afternoon ...
When I moved from Bristol to Perth, Australia 2 years ago, ARP #3 didn't enjoy the voyage, refused to power up when we got here and is currently with the good technicians at EAV in Morley. It is being represented here by a colour photocopy (photokarpy) sellotaped onto some cardboard.
But there are lots of plans afoot for myself and the Odysseys.
Ambient gigs, Raves, Classical stuff, Weddings, Sausage Sizzles ...
I'll keep yous posted."
