A pre-owned Elektron Digitone MKII in excellent condition. It comes with all original packaging and accessories.

Manufacturer's description
Step into a new realm of sound with the Digitone II, an evolution of Elektron’s original FM synthesiser, now offering expanded polyphony and enhanced creative control. With 16 tracks (versus the original’s 8) and a flexible 16-voice polyphony, you can unleash complex soundscapes across synth or MIDI tracks. Digitone II introduces four selectable synth machines (Wavetone, Swarmer, FM Tone, and FM Drum) and six dynamic filter machines, providing far more sonic variety than its predecessor. The improved 128-step sequencer, along with Euclidean sequencing and advanced modulation options, invites you to explore limitless creative possibilities. Packed with powerful effects, deeper sound-shaping tools, and a modular workflow.

Expanded Polyphony and Synth Machines:
While the original Digitone offered 8 voices and 4 synth tracks, the Digitone II doubles the polyphony to 16 voices and expands the tracks to 16, allowing for far more layered compositions. In addition, the four new synthesis machines (Wavetone, Swarmer, FM Tone, FM Drum) go beyond standard FM synthesis, offering greater creative potential for crafting rich melodic, rhythmic, and percussive sounds.

Enhanced Sequencing and Performance Features:
Digitone II features a 128-step sequencer—twice the length of the original Digitone's—enabling more complex patterns and compositions. The addition of Euclidean mode per track offers a fresh approach to sequencing, making it easier to generate evolving rhythms. With individual pattern length, time scale multipliers, and enhanced trig conditions, the Digitone II’s sequencing features are a leap forward from the original, giving you deeper control over your compositions.

Advanced Modulation and Effects:
The Digitone II builds on its predecessor’s modulation and effects capabilities, with three assignable LFOs per voice (up from two in the original) and added effects like digital overdrive, bit reduction, and sample rate reduction per voice. The inclusion of master effects like the stereo compressor and overdrive means you can fine-tune your final mix, while send effects like Saturator Delay and Supervoid Reverb add depth and dimension to your sounds."

Manufacturer's description
Experience the Power of Three Oscillators and a Ladder Filter with the Trigon-6 Module

The Sequential Trigon-6 desktop module delivers the same massive sound and hands-on sonic control as the Trigon-6 Keyboard. It features the same pure analog signal path with discrete oscillators and filters, and the same high-quality digital effects. It also has the same intuitive layout with full-sized knobs and switches that make it quick and easy to shape new sounds.

The Trigon-6 module sounds huge — just like the keyboard, because it is the same six voice polyphonic instrument, just in a smaller form factor. And if you want even more polyphony, you can use the poly chain feature to link any two Trigon-6s for a stunning twelve-voice synth!

A Sound That is Bold and Familiar

The Trigon-6 is Sequential’s polyphonic take on the classic, thick and creamy, 3-oscillator-plus-ladder-filter analog sound that defined the dawn of the synth era. It’s a sound that bridges genres and styles — now refined and redefined with Sequential’s own modern imprint.

PM Foundations Variable Filter Bank no. 4

"Here's another demo of the PM Foundations Variable Filter Bank. This time, there's no talking, just knob turning and sound. I wanted to see what sort of vowel sounds I could get. I'm using one bank, one EG for modulating the filter, one EG for the amplitude, and a bit of the unfiltered signal mixed in. When my hand disappears, it's fooling with the filter EG."

Granny’s back with a brand new lid: our classic desktop granular sampler gets a facelift, bringing her into the modern age with enough usability upgrades to last another lifetime, rehomed in sleek black PCB-material to help it look the part amongst the latest in the Bastl range.

The Microgranny 2.0 that you know and love is still there under the facelift: lo-fi sound full of character packed into a hands-on monophonic desktop sampler that is a joy to experiment with. Plug in your microSD card loaded with 8-bit samples, or record them live through the in-built mic or line input, and jump into play with 6 samples right under your fingers, or instantly recall up to 60 saved presets.

Playability is paramount
The two-tier menu lets you dart between editing grain size or warping the playback speed, and the new-look tactile knobs grant better control than the previous model. The hazy plastic case is gone, and the PCB case’s sharper text makes the modes under the new and improved buttons more enticing – delve into Randomized mode, Legato playback, or the Instant Loop function to extend the virtually limitless possibilities of the surface controls yet further.

MIDI Control? Yep: play specific grains with keys, control the CC values remotely, even clock-sync loops and grains. Take your Granny for a walk in the park with the battery power, or run it through a wired 9V supply."

Defect Processor Buchla 289

video upload by Memetune Studio

"A few months ago I managed to snag a Defect Processor Model 289 made by Alex Pleninger (Keen Association) and Roman F

This hyper-rare module adds some appropriately bonkers digital FX to the Buchla 200 series system, by using two independent stereo digital effects units based around the rather interesting Spin Chip platform (it has two of them inside)

The module takes any audio signal and subjects it to various Spin Chip algorithms - there are 8 per section, and they are pre-set on EPROMS on the board behind the panel. The good news is you can swap out the EPROMS and change the 16 algorithms if you so desire, and you can even create your own if you get the Spin Chip programmer

I have a set that includes this insane delay patch. The module has CV inputs for some of the parameters (not many Spin-based products have this facility AFAIK) but here I am playing around with the delay times and feedback levels by hand

I’m also tweaking the 259 timbre, the LPG decay time, and the mix between Noise and VCO, and the Bandpass filter

Crazy sounds and defects abound!"

Granular synthesis redefined

Break your samples apart to build new and unique sounds

Play any audio file like a synthesizer-in tune with your song

Explore a new world of sound design with audio as your raw material

A firestorm of granular power

Grainferno is an advanced granular instrument built around a new way of synthesizing sound from existing audio. Its next-gen grain engine breaks your samples into microscopic fragments and rebuilds them into entirely new textures.

From pristine tonal clouds to experimental digital noise, Grainferno turns your sample library into an endless source of playable inspiration.

Make a synth from any sound

Grainferno can generate grains at speeds fast enough to cross into the audio range. At these rates, grains stop behaving like texture and start acting like oscillators-turning any audio file into a playable synth voice.

Even at audio rates, traces of the original sonic character remain, giving you unique synth building blocks with the spectral fingerprint of your source audio.

Add modulation and grain-level shaping to build ready-to-use granular synth tones that stay in tune with your song like a traditional synth.

Moog Opus 3 — "New Old Stock" Sliders, Switches, Controls, Control Caps & Knobs SN 5828

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

via this eBay listing

"The Moog Opus 3 is a vintage polyphonic synth that combines string, organ and brass sounds in a four-octave keyboard, along with flexible controls for shaping each sound.

One of the coolest things about the Opus 3 is that it has a classic Moog four-pole filter that the brass and organ can be run through. The filter has the sound Moogs are famous four, and it can be run into self-oscillation.

The synth also features a three-phase chorus effect that uses the famed Reticon bucket brigade chips, as well as stereo and mono outputs.

Here are details about the unit for sale:

The old, deteriorating foam that sat below the control panel has been removed from this one, so you don’t have to worry about it.

All of the sliders, switches and rotary controls — except for the master volume — were changed out for New Old Stock replacements. All the slider caps and control knobs are New Old Stock as well. Everything works smoothly, with no noise or issues.

The master volume has very minor crackle at the top end of its range while it’s being moved. It is otherwise noise-free during normal operation. I would have had it changed out but it wasn’t possible to source an original replacement.

One of the three original Reticon chips in the chorus effect was replaced when an original failed. All three are working, and the chorus sounds great.

The original red LED in the Modulation section was swapped out for a new bright blue LED.

I wasn’t able to test the sustain jack on the unit’s front panel. Moog chose an unusual size jack here— it’s slightly smaller than a 1/4-inch input. It would be easy to swap it out with a proper 1/4-inch jack if you choose to do so.

The physical condition is very good. Note the scratches to the wood and some minor marks on the faceplate.

All of the notes sound as they should, and all controls and functions work as they should.

HELPFUL NOTES
Although its functions are basic, you’ll need to understand the signal routing in the Opus 3. These are spelled out in the owner's manual (which is available online), but knowing the following will help you get your head around it.

For example, the chorus effect operates on the strings and organ, not on the brass. This is by design and is noted by an arrow on the control panel.

The Moog four-pole VCF can be used on the organ and brass, not the strings. Again, this is by design and is noted by an arrow on the control panel.

Frequency Modulation works on all sounds, but VCF modulation only works on the organ and brass because these are the two sounds that can be run through the VCF (see the point immediately above). Again, this is by design.

The length of chorus delay is set by using the delay fader in the Modulation section. This too is by design.

Two other noteworthy points:

• The pitch wheel has a firm detent (the point at which it sits at pitch). Other owners have noted the same thing about their units in online forums. It’s not difficult to work, but it’s firmer than on other synths I’ve owned.

• All of the electronics, aside from those mentioned above, are original and working fine. Electrical components can fail or become damaged with time and/or misuse. Always be sure you are connected to proper voltage, and note that ground loops can introduce hum."

Moog DFAM+Labyrinth 50 Combo Patches + Samples. Sound Demo

video upload by Anton Anru

"🥁 'Modular Impulse' is a collection of 50 combo patches for the semi-modular analog synthesizers Moog DFAM and Labyrinth.
The soundset focuses on rhythmic and dynamic sound design, as both synthesizers are naturally oriented toward punchy, percussive tones.
🧿 The collection includes basses, plucks, bleeps, drums, leads, and FXs.
There is a wide range of sound colors inside the pack: massive and gentle, aggressive and soft, bright and dull, melodic and inharmonic tones, as well as straight and polymetric patterns.

📦 The patches are available here: https://antonanru.sellfy.store/p/dfam...

🎛 The main idea behind the soundset is a high level of interconnection, rather than simply syncing the synths with independent timbres (individual patch collections for DFAM and Labyrinth are also available on my website).
In this patchbook, the timbres of the synths are tightly intertwined and cannot exist separately:
