"Ticks all the boxes - 30 voices, reskinned with striking black theme, extra overlay, upgraded Kilo knobs (currently $10 or more *each*), power supply.
Oh yeah, and it sounds amazing as well. If you're looking for an old school Waldorf wavetable sound, this is your best choice. Still classic sounding, but with a lot of modern touches.
Fits in a rack, looks great on a coffee table, can be safely lugged to gigs. I have 2 and still debate keeping this one."
"In this video I share a walkthrough and demo of Meta Module made by 4MS. MetaModule is a Eurorack module that can act as a virtual modular synth, letting you swap out different modules and build virtual patches that you can interact with using the front panel knobs.
I'll start with an overview of what Meta Module is and how it works, then I'll walk through two different ways of building patches using Meta Module (directly on the module itself and using VCV Rack on your computer), and I'll share multiple different use cases for which Meta Module can be especially helpful. I'll also share lots of demos, patches, and sounds along the way!"

"This is my Antonus 2600 - I just completed building it from the synthCube.com full DIY kit. It is a huge project! Working on it in my free time, it took six months for me to complete. But I'm sure a full-time builder could do it in a couple of weeks. I actually love that it took me this long. :-)
Anyway, since I first powered it up I have been testing, calibrating and starting to understand how it works, and yes, it deserves it's reputation as an awesome sounding and very flexible synthesizer.
This video is just me noodling on it using the Arturia KeyStep Pro with a sound/patch I really like. This is actually just one of its three oscillators, but I have the saw and square waves patched in. The other two oscillators are in LFO mode. The oscillator is using the ADSR envelope and the filter is using the AR envelope plus an LFO to modulate it - makes some interesting accents.
Effects are courtesy of the Fractal Audio VP4, which is an incredible pedal.
I thought adding some drums would give this more of a musical context, so I force-fit some patterns from EZ Drummer.
The opening groove is definitely reminiscent of Bluetech's Laika, from the Spacehop Chronicles album. It's intentional. :-) I really like his stuff! Go buy some at Bandcamp.
This signal path for this recording goes like this: 2600 into VP4 into iRig into iPhone. I then applied a little EQ in Studio One, just to trim out the extreme highs and lows - I did not use any compression on this.
Can't wait to make some "proper" music with this amazing synth.

"Commonly audio Crossovers split an audio signal into several frequency ranges so that each resulting signal is adequate for the speaker drivers they are connected to, usually low range is sent to the big woofers, mid range to smaller woofers and high range to the tweeters.
Here we introduce our ADDAC607,a mono 3 band Crossover featuring 4 pole, 12db Sallen-Key active filters and volume controls for each band. Although ADDAC607 operates in Mono (for Stereo signals two modules can be used) there are 2 audio inputs that allow an easy way for Stereo to Mono summing. The [MONO SUM OUT] carries this summed signal. This output is pre-gain and can also be use as a buffered Thru output.
The possibility to split the signal into different bands makes possible several usefull processes, as examples: - Independently process specific frequency ranges like adding delay only on the high range band - Split a signal to feed 3 compressors for multiple band compression - By controlling the [GAIN] knobs they can act as “kill” switches in DJ mixers to remove a whole band from the mix
This module is also a great companion for our ADDAC220 Dual Envelope Follower+ allowing to extract the dynamics from any signal in a focused frequency range allowing to, as an example, separate a kick drum from a snare.
There are three switches to select the bands operating ranges: 2KHz, 4KHz and 8KHz for the high range 370Hz, 620Hz and 1KHz for the low range
The three [GAIN] controls set the volume for each band. At noon they are unity gain, fully CW they are x2 amplifiers."
"Behringer's BM-15M Murf Box - now renamed as the BM-15M Resonant Filter - is a clone of the Moog Moogerfooger MF-105 MuRF. I bought this pedal thinking it might be a more interesting replacement for my Boss SL-2 Slicer. Why did I want to replace the Slicer? Because the Slicer has a few things that slightly irritate me. In hindsight, a pitiful motivation since the Murf Box has an equal number of small irritating things.
First, if you bypass the effect you only get sound out of one channel. That's irritating. It's huge, the knobs are hard to read, I don't love the EQ, the way the envelope works is odd, there's no compression on the drive, and you can't adjust the LFO without an expression pedal. Not that I entirely blame Behringer, I also blame Moog since these are all present on the OG Murf. But of course all the actual blame rests with me for not being satisfied with the Boss Slicer.
Not that the Murf sounds bad. It's a rather interesting, gritty, unusual and reasonably versatile machine. I think rather my expectations were pumped up to the same artificial heights as the OG Moogerfooger reputation and prices.
Here the Murf is receiving a MIDI clock and the expression pedal is connected to the LFO rate. The volume varies a lot depending on the EQ, mix and drive settings - and seems to fade away a bit toward the end of the video - but I thought it best to keep these as-is to show real usage.
Originally I was going to do a comparison between the Murf Box and the Boss Slicer with lots of talk. But knowing that hearing me talk too much annoys some people, and that merely showing a Behringer product will guarantee a percentage of automatic dislikes, I thought it wiser to start with a plain audio demo. I'll do a comparison with the Slicer very soon (unless everyone hates this video) since I think there's a lot of overlap and interesting design contrasts between the pedals.

"The 1966 Johnson Intonation Trainer is a rare and intriguing instrument developed by the E.F. Johnson Company of Waseca, Minnesota. Originally designed to assess pitch-matching and pitch-discrimination abilities, this device has garnered attention for its unique features and potential applications in modern music production.  
One of the standout characteristics of the Johnson Intonation Trainer is its full polyphony, allowing all 37 keys to be played simultaneously. Each key is associated with its own oscillator, enabling microtonal adjustments and the exploration of unconventional scales and tunings. The instrument offers four distinct voicing options, ranging from basic sine waves to more complex, reedy tones. Additionally, the “Scale Selector” switch provides a choice between standard tempered tuning and a tunable mode, with individual “Tunable Scale Controls” corresponding to each note on the keyboard for precise pitch calibration.    
Housed in a robust fiberglass case, the Intonation Trainer features a built-in speaker, though it can also be connected to external amplifiers or mixers via standard 1/4” outputs. Some units include a vibrato effect, though functionality may vary between models. 
In contemporary settings, the Johnson Intonation Trainer has found a niche among experimental musicians and sound designers. Its ability to produce rich drones and facilitate microtonal exploration makes it a valuable tool for creating unique sonic textures. The instrument’s vintage analog circuitry imparts a distinctive warmth and character that is highly sought after in modern music production.
Due to limited production and the passage of time, functional units of the Johnson Intonation Trainer are exceedingly rare. Finding one in full working condition, complete with original documentation, is a remarkable discovery for collectors and enthusiasts alike. The scarcity of this instrument, combined with its unique capabilities, underscores its status as a treasured piece of audio history."
"Made in 1966 in Waseca, Minnesota by the E. F. Johnson Company. Originally designed as an ear training and intonation device, but in practice it is a unique fully polyphonic analog synthesizer with extensive tuning control. Very few were made, and surviving examples in this condition are vanishingly rare.
"The debut instrument from Circle Cynths, OBSO. A dreamlike interface delivering instant inspiration, featuring nostalgic synths, pads, basses, bells, and strings, all sampled using obsolete technology.
"OBSO is an inspiring catalog of sounds coaxed directly from various forms of obsolete media and extant technology. We celebrate the undulating inconsistencies of bygone days, lovingly filtered through the oxide and worn machinery of VCRs, cassette-decks and other consumer products from the 80s and 90s.
Our dreamlike but intuitive interface is intended to spark instant emotion. Specifically designed to sound good no matter where the knobs are, the five visceral control circles nevertheless offer a huge depth of range within a single patch. Nostalgic synths, creamy pads, lush basses, shimmering bells, burnished brass, scintillating strings, and more glow with the patina of fine age.
Individual sounds sink into a mix like they always existed, but you'll find they can easily stand alone without the need for layering or manipulation outside of the instrument. From film and game scoring to lush pop records, these tactile soundscapes add a dose of warm nostalgia to nearly any production.
Simple Interface
Sculpt your sound with an intuitive interface that features massive depth of control, giving you endless ways to shape and refine your tone.

"🌌 Noise of Oblivion is a collection of 50 atmospheric presets for the U-He Zebra 2 virtual synthesizer. It features 5 drones, 16 pads, 7 rhythmical, 12 strings, and 10 textures. 🏙 The soundset contains dark, cinematic soundscapes that evoke the atmosphere of a sci-fi thriller, dystopian world, or intense drama. This carefully crafted collection delivers a wide variety of timbres designed to take your productions into uncharted sonic territory, blending futuristic tones with a vintage edge.
"Using some crude paper animations and the Sonicware Liven Evoke as demonstration platform, I explain a whole bunch of parameters of granular effects and synthesis—both what they are and how to use them: buffer, spray, diffusion, direction, shape, feedback, alignment, range, jitter, and more. From a filming/editing standpoint, this is the most elaborate video I've ever made, so I hope people like it...
This video also features very brief cameos from the Texture Lab & the @HologramElectronics Microcosm."
"It took me 6 weeks to develop the editor because I had to reverse engineer 3729 Program SYSEX bytes with no specifications; and implement 701 NRPN commands with partial specifications. It is the most complex MIDI implementation I’ve ever seen.
"WORKING CONDITION: Fair - All keys and cassettes are sounding and operational, except for both "B" Keys. You can hear some light hiss when pressing the keys but no sound. The output volume knob does not adjust, so presently the volume is fixed, but fortunately, it is at high volume. About 4 of the tuning knobs don't change the pitch but the rest are adjustable to varying degrees. When the drum track is turned off, you can still hear it bleed through the output faintly. We can say that it is mostly working and usable for some creative inspiration, but it could probably use some cleaning and perhaps some servicing by a tech.
The pack includes an instruction manual and what appears to be schematics, so it is serviceable. Also includes instructions on how to swap out the Walkmans, so you can keep this thing going for a long time!
PHYSICAL CONDITION: Good - This is a 1-of-1 custom-built "Mellotron Style" keyboard that runs off of 14 Memorex "Walkman" cassette players. The lid is hinged at the back and when closed does not fix to the front by design, so you can access the cassettes conveniently. The keys are a little uneven but that is all part of the charm of this unicorn. All the keys are stable otherwise and so is the rest of the unit.
See and hear the video of this very unit at the end of the photos.
INVENTORY #55795
BRAND: Mike Walters
MODEL: The Melloman
FUNCTION: Mellotron Style Keyboard
PRODUCT DESCRIPTION: This listing is for a Mystery Circuits by Mike Walters, The "New" Melloman Mellotron Style Keyboard.
You can swap out cassettes with your own recording samples on them to get that warbly aged Mellotron style sound with any tone. Currently, the cassettes have a Polymoog Vox Humana on one side, and female vocal on the other.
From the Mystery Circuits Website:
"This is the new Melloman, built eight years after its predecessor. It was commissioned by Justin Vernon (Bon Iver, Volcano Choir), and took me a little over a year to complete. Like the original Melloman, this is my DIY design of the classic Mellotron. There are 14 Walkmans inside the Melloman, running tapes of continuous notes. Each tape has two octaves of a looping sound, and those sounds are routed to the output when a key is pressed on the keyboard. The new Melloman is a complete redesign of the original Melloman I built in 2005"- Mike Walters
The website and page for this item is still active for those who want to do more research. Simply search Mystery Circuits and find 'The New Melloman 2013'."
"This particular Q has 32 voices. Pictured with it are the brass endblocks I put on it, but I will include (or reinstall if you like) the original wood ones. The knobs and power supply were replaced by a previous owner. Feel free to ask me any questions!"
