It appears to have an original red Surrey Electronics case, compared to this racked one. You'll find a spec sheet there as well.

"Surrey Electronics Spectrum Shifter

Uses the same principle as Bode frequency shifter. Ostensibly for 'Howl Reduction' but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. Very good with other fx. Great studio addition as you can plug allsorts in not just for vocals.

31cm x 27cm x 24cm
240v unit

Mono input and output via 1/4" jacks on the rear. (standard 'guitar' Jacks)
some scuffs and slider plastic is missing, did not replace as does not affect use. See photos."

BugBrand Introduces TCS - Touch Control Sequencer

via BugBrand (For those in the US: check on availability with Noisebug per below)

"The 5FW design stems from ideas I used way back in the Old Blue days when I had the CTL1 Touch Panel - that design went through a few iterations during its 4 years of life, moving from just a control/preset device to incorporating some basic sequencing. Now I have taken it several steps further - expanding it out to 8 steps and increasing the control & sequencing options. The result is a powerful little hands-on sequencing hub! It can link up with other clocking devices, especially the Sequence - indeed, I'm just beginning to investigate a joiner/expander for the pair that would allow the Control link to be easily switched on/off and also incorporate a handful of other useful functions.

In the meantime, the first modules are starting to ship - they can either fit in a larger system or sit in a 5FW case - perhaps an interesting addition to other banana systems!

US shipping & Tariffs:
There has been a fair bit of uncertainty because of new tariffs on shipments into the US (10% from UK vs 20% or more from most other places), alongside the ending of the De Minimis exemption for shipments under $800. Given that I send a fair amount to people in the States, these changes have proved worrying!

Thankfully I've been able to jiggle things around and have found that I can still send things easily & affordably - indeed, often including pre-payment of tariffs while not raising the overall shipping cost, and sticking with Royal Mail who have proved so reliable over many years of use.

Noisebug:
But, alongside these changes, I'm rekindling my prior work with the wonderful Noisebug store of Pomona, California. Just today I've sent a reasonable initial load - a couple of 1Frame systems, several mini-systems and a handful of red designs.

As you know, I've tended to work directly with people worldwide, but have kept in with a very few small & specific stores - Noisebug really fit the bill here for me! So if you've got requests, feel free to get in contact with them - or continue to nudge me direct ;)"

New Roland TR-1000 RHYTHM CREATOR Incoming

Update: teaser videos added below.

This one was sent in via an anonymous reader. It's apparently from a Sweetwater catalog.

The text reads:

"NEW!

Meet the TR-1000:
Roland's Legacy Rhythms Reborn

Blueprinted with unprecedented potential, the Roland TR-1000 Rhythm Creator marries historic heat, analog presence, and digital precision into a polychromic powerhouse built on the masterfully re-created circuits of the legendary TR-808 and TR-909 drum machines. Its hybrid architecture houses a trio of synth engines, bringing a prismatic palette of FM, PCM, and VA possibilities to the TR-1000's analog foundations, with ACB modeling supplying the coveted circuit-bent sonics of the 8X and 9X models. Over 2,500 onboard sounds join a wealth of digital and analog effects while the suite of classic-to-contemporary connectivity effortlessly integrates the TR-1000 into any arrangement. Add in cutting-edge Morphing performance controls, next-gen TR-REC sequencing. true-stereo re/sampling, and an unbridled array of sonic contouring tools, and you've only scratch the surface of the TR-1000's kaleidoscopic capabilities — vintage heart, modern soul. and endless exploration waiting to be discovered by you."

If legit, I'm curious how it will compare the the TR-8S. Note the change in design aesthetic. Reminds me of the GAIA with a touch of Elektron gear. Note the Morph slider on the bottom right and display on the top right.

Update2: Roland announcement post here, additional posts with demos here.

EMS Synthi A stolen from Synthorama

Some unfortunate news sent my way vis Swissdoc. Apparently someone has stolen an EMS Synthi from the Swiss synth museum Synthorama. You might recall the video walkthrough just posted here yesterday.

The following is via the curator of Synthorama, Martin Hollinger aka Airböurne (creator of the modular synth by the same name), on the Sequencer.de forum (translated via Google):

"Hello everyone

I finally managed to register on the forum. I'm the owner of the Synthorama and, due to a current event, I'd like to give you a brief update on the museum.

The Synthorama has been around for 25 years and serves to introduce synthesizers to a musically interested public. Almost all instruments can be played and tested here.

But you all already know that ;-)

Unfortunately, there are also people who misuse the museum. Since its inception, there have been four thefts, the fourth on August 2, 2025.

The first was about 15 years ago, when someone stole around 10 modules from one of my Moog modular systems while it was unattended and then filled the "holes" with other modules or even front panels. I didn't notice this for a long time because it wasn't that obvious.

Whimsical Patching

video uploads by Whimsical Raps

Playlist:

1. Whimsical Patching // 1. Audio-Rate Modulation

from Dani:
"One of my favorite aspects of modular synthesis is that signals we can hear are made of the same basic building block as signals which provide control and modulation -- they're all just voltage moving at different rates!

When we use an audio signal in the place of control voltage, we're touching into a technique broadly known as audio-rate modulation. Using audio-rate modulation in the Whimsical Raps ecosystem is incredibly rewarding, as it can unlock unexpected behaviors in familiar and new modules alike.

Here, Mangrove (our formant oscillator) modulates Silhouette's (our new 'signal combiner') SPOT, which is mixing six audio channels from Just Friends (our six-voice digital oscillator). I noticed that sending Mangrove into SPOT bleeds Mangrove's audio signal into the mix, so I tuned Mangrove to harmonize with Just Friends. This endowed FORMANT changes with new power, adding harmonic depth to the chaotic modulation -- notice the sizzle around 0:30 as FORMANT is cranked up.

Once INTONE adds distance between the ratios of Just Friends' oscillations, I reduce FORMANT to a low-frequency grumble -- I particularly enjoyed Silhouette's delayed vocalizations of these changes across the stereo field. Manually scanning SPOT offsets the input channels we're highlighting, which reveals the new INTONE-spread pitches. Increasing FORMANT introduces audible discontinuities as Mangrove regains its pitch, which are unique in the left and right channels. A final INTONE adjustment is added for performative spice, which is caught by the bucket-brigade device for a muted splash of stereo color."

ARP 2500 Modular Synthesizer w/ Pair of Fully Loaded Wing Cabinets

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

This one was spotted and sent in via
M Me.

"Vintage ARP 2500 Modular Synthesizer system. Accompanying the ARP 2500 main cabinet is a pair of fully loaded wing cabinets. The main cabinet and keyboard were fully restored by Phil Cirocco (CMS) around 2011 as well were most of the modules in the wing cabinets. However the system has not been powered up or played since 2018 when I moved from Los Angeles to Tucson Arizona. It was working perfectly in 2018. Since sitting for 7 years the system will most likely need some small service to get it back to perfect. IT IS UNTESTED AND WILL NOT BE TESTED. IT IS BEING SOLD AS IS.

The previous service was meticulously done to satisfy my serious demand for the system to remain as original as possible. No modifications were done and all parts replaced with original or appropriate parts. The system is hyper clean in person and was clearly babied. It was used on notable lp's. You may live a 100 more years but will likely never find a better more complete ARP 2500 for sale. This system is priceless and was the most expensive new instrument when it was produced in the early 1970's.

I collected and played many Moog, ARP and Buchla modular systems. However owning so many systems became a burden. As well, switching between using Moog, ARP and Buchla took too much bandwidth. I sold all of my Buchla systems and this is my last and best ARP piece from my massive collection. Time for someone else to own it

CAN BE PICKED UP IN TUCSON AZ OR I CAN DELIVER TO LOS ANGELES CA"

"The sampler has been completely refurbished. The casing has been painted black. All tact switches have been replaced, the old LCD with a new LED and pad sensors. Additionally, I have installed the Gotek FDD emulator (32GB Sandisk pendrive included), the latest Vimana 3.15B OS, max RAM memory and multivoltage power supply. This means that it does not need step up or step down converters to work! The voltage switches automatically depending on the place in the world. It accepts AC voltage from 65 to 265V. This is probably the only such version in the world. I was going to replace the LCD window, as it has a few scratches, but I'll leave that to the new owner. The glass is available on eBay, and replacement is easy (double-sided tape). Insured shipment."
