7/16/23 DEMO: Maestro Rhythm King MKIV (for sale) chops TTMC and Trogotronic

video upload by Cfpp0

"This Rhythm King is the true King of rhythm machines because it has an internal modulation circuit that gates your external audio to correspond to the pattern of the beat. You have control over the modulation depth and volume. You have control over the beat volume and the balance between drums or cymbals. You can combine more than one pattern to generate new patterns. For this demo I am playing continuous notes on the TTMC 112, which CVS the 158 oscillators, and the 112 gates the Trogotronic m11 and also sends pressure to the drive input. The output goes to a 106 then to a passive Rucci matrix mixer (I was going to make the modulation circuit feedback on itself a bit, which sounds cool BTW) and into the modulation circuit where the Rhythm King slices and dices. Buy it at Christopher’s Boutique 489 on Reverb!"

via this auction

"This is a rare Maestro Rhythm King Mark 4. It is VERY different from the more common and more colorful Maestro Rhythm King (we have it too if you want to buy it). The biggest difference is that the MKIV has an external audio input, which gets fed into a gate circuit that follows the rhythmic patterns of the preset pattern you choose on the drum machine. Check the video in our photos and cut to 2:45 to see and hear how it works.

You can blend the drum sound using a fader to go fully hats, to be mostly kick and toms, or anywhere in between. The volume for the external audio has its own volume fader, as does the drum volume, so you can also use it just to modulate audio and not use the drums. There is also a blend fader for the gate on the external audio, so you can dial in how much of an abrupt cut you want."

Gearfest UK 2023: PWM Mantis Synth Is Coming Along

video upload by sonicstate

"We spoke to Paul and Ben from PWM at Gear Fest 2023, where they provided an update on their Mantis synthesizer. The Mantis project was initially started by Chris Huggett, and Ben has taken over the firmware development since Chris's passing. The Mantis is now in a working state and producing impressive sounds. Ben discussed the challenges of refining the code and turning the proof of concept into a fully functional product, addressing features like the multi-mode filter and ensuring compatibility for production. Paul mentioned that the firmware and sound patching would require a few more months of development before moving into mass production. The Mantis is expected to be available for purchase in October, just in time for the pre-Christmas rush."

7/16/23 The sound of a Viscount PCM 64S dying :(please send schematics :)

video upload by Cfpp0

This appears to be the first post to feature the Viscount PCM 64S.

"This rare and feature-packed (trigger in, out, individual snare out, footswitch jacks for break, clap, and start, volume knobs for six categories, 2 clap variation buttons, three percussion cancel buttons) preset pattern drum machine worked fine every time. Yet it wasn’t getting used enough and was put in a storage box and listed on Reverb. It sold, so it got pulled out for a final test (as one does) before shipping. What evil invisible specter lived in that box? Not sure, but it flew this Viscount over the cookoo’s nest and now this once glorious machine just ratchets and glitches. I opened it up and saw no bulging or leaking capacitors or obvious issues. We have a tech who is willing to fix it, and the previous buyer is still willing to buy it once it’s fixed, but we have no schematic. Viscount was an Italian company and restoration of antiquity is one of the many things at which Italians excel. So, if you have a schematic, posso avere? Ti prego!"

Patching the Octave Cat

video upload by boxoftextures

"Another amazing vintage synth recreation from Cherry Audio, this time the Octave Cat. Although possibly it should really be The Cat, from Octave. Either way, it's fun to program and sounds great. Always wanted one, back in the day. They also made the Kitten, a smaller version, and the Catstick, a joystick you could hook up to your other synths. Still want one of those!

And the Cherry Audio software version is excellent. It has character, and power. And it adds an extra page the original didn't have, with effects and a sequencer. Oh, and adds polyphony too. But it was the '70s, and we didn't really have such things back then, or at least most of us didn't.

In this video I'm making four patches from scratch. As usual. What's a little different is that I usually make a few before recording a video, just to get a feel for the synth. For this one though I just dove right in, so at times it may have taken me a little while to notice things, or figure them out. But it's not an overly complicated synth so wasn't a huge issue. And it sounds great. Which I may have mentioned before LOL


Patch of the Week: TRIPLE CROSS - Voltage Controlled Sound Switching with a Step Sequencer

video upload by AJH Synth Official

"The Triple Cross crossfader/panner module from AJH Synth & Tone Science makes a lot of things possible. Here it is being used as a voltage-controlled switch, to change between 4 incoming sounds, and send the chosen sound to its output. This means it can serve as a very convenient method of changing between multiple sounds, perhaps in a live performance, moving between different patches manually using the sturdy, tweaking-friendly controls. However, this behaviour can also be controlled by CV, so the process can be automated, and controlled by other modules, keyboards and sequencers.
In this patch a 4-channel/track step sequencer is being used - the excellent Erica Synths Black Sequencer. One sequencer track is used to send a melody to the VCOs and Gates to trigger the envelope generator. The other 3 tracks are controlling the 3 channels of the Triple Cross, to pan the Fade control hard left or right, like junctions on a railway track, so that the exact sound of our choosing arrives at the module's output, precisely when we want it.
Various combinations of the 3 VCOs, white noise, sub-octaves/sub-basses from the Ring SM, and animated sawtooths from the Wave Swarm are sent to 4 separate filters: The Transistor Ladder Filter, Sonic XV Diode filter, and both filters of the Gemini 2412 Dual VCF. A single Dual Contour Generator is controlling the VCA level, and the frequency of all 4 VCFs. The Sonic XV is also using its wave folder to generate a more unusual timbre from just a single triangle wave. The Triple Cross is a collaboration between AJH Synth and Ian Boddy of the Tone Science record label. It is an exceptionally useful module, being suitable for use with both audio, and control voltages, since it is DC-coupled. More videos featuring this, and other modules in the future.
Tone Science Label:

The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself."

Korg PS-3100 Its Alive!

Pics of the inside below.

"Aesthetic condition 7/10

Electronically 90%

Functionality 65%


The instrument turns on and makes sound. Keybed is working via the trigger output fully and trigger all notes, however some note behave differently and randomly. This most likely cause by the cracked pcd slots, which is a n issue with most ps-series synths. I recommend you take a look at the youtube video.

Wave forms, vco, is working and can select pulse, saw, noise etc. Other functions seem to be functioning correctly via the eg output. Also all other functions on the control panel seems to be working as it should.

Buttons and knobs are working, but need work or replacement as there is some crackle and noticeable hiccup especially with the switches and selectors. This probably needs cleaning or replacement.

Originally when i bought this synth it did not turn on, so I asked the tech to change all the capacitors (about 100) to see if it will turn on and make sound safely.

As mentioned above, the pcb slots are cracked and need replacement. There is a 80% chance that after replacing these slots, the synth will work properly but i will leave that judgement to a pro.

Also some retracing or treatment need to be done, due to corrosion (10%). I have more photo's and video's available, a drive link can be shared to see."
