Waldorf Microwave II 30Voice Expanded

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


via this Reverb listing

"Very good condition Microwave 2 with the expanded voice card for 30 voices and expanded FX. This essentially a Microwave 2XT without the knobs or external input. You could remove the expansion board and place it into an XT and gain the 30 voices. You would be left with a 10 voice Microwave 2 with the latests revision board. I sent this into Waldorf to have this mod done years ago. All of the encoders work and the display is crisp. Minimum rack rash if at all. This is close to one of a kind."

"The legendary SuperSaw waveform, essential for massive trance leads and pads.

40-note polyphony and powerful analog-modeling sound engine.

Onboard vintage-style Arpeggiator and Realtime Phrase Sequencing (RPS).

Built-in Voice Modulator for classic vocoder and robot voice effects.

Intuitive, hands-on control with an abundance of knobs and sliders for real-time sound shaping."

Two separate listings.

"Original EMS Battle Prestopatch.

This thing is very rare and cool as heck."

EMS SYNTHI via via this Reverb listing

"This is a beautiful cream faced EMS Synthi A in fantastic condition. The case hardware shows some age and there is some mild scuffing on the bottom back of the ABS plastic part of the case but nothing that stands out. All mods built and installed by Robin Wood at EMS. Since I have owned it, it’s been kept in a padded case (included, see photos) in my climate controlled studio. The panel, pins, jacks, pots, guts, etc. are as good as new.

Aesthetics: There are labels applied by EMS that indicate the mods/expansions. As mentioned above, the metal case hardware shows some age, I took pictures of everything to be clear on aesthetics.

The mild scuffing on the ABS is not really noticeable to the eye but you can feel it if you run your hand over it.

I have included images of the pages in the manual that explain all of the mods and how they function. This is an amazing Synthi A that is 100% functional and clean with extras that add new dimensions to this classic beast."

crucFX SLM (scrollfo + mobvrt) via this Reverb listing

"SLM is SCROLLFO + MOBVRT.

This utility instrument contains x4 SCROLLFO, and x4 MOBVRT.
————————————————————————
SCROLLFO is a unique LFO circuit based on the original scroll circuit from Peter’s SIDRASSI/RAZZI/TETRASSI/RAZZI units.
But expanded upon.
You have an on/off/on round button switch that allows you to momentarily activate the LFO, or latch it on, when the button is released or in the off position, it samples where it was at in the lfo cycle and holds that value, to give you the ability to generate random pitch voltages/CV voltages.
This button also has a pulse input that allows you to trigger the switch hands free.
flanking each side of the big lfo button are the 2 square buttons - one pulls the signal to ground, and the other pulls the signal to mido.
These 2 buttons also have CV inputs that allow you to fight against the LFO (when it is active) or to set virtual ground and ground on other gear.

MOBVRT is a MIDO biased OFFSET, BOOST, and ATTENUVERTER - giving you the ability to move your @ciat_lonbarde signals anywhere you want in the unipolar boundaries!
Think an offset/attenuverter module for eurorack, but specifically for ciat-lonbarde voltage levels!"

Video & Performance by @DreamsOfWires

The AJH SYNTH Eurorack modular 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.

Official website page: https://ajhsynth.com

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."

4/8/25 (octaves overlay) SWTPC Psych-Tone + ADR Pan Scan + Eventide H3000B


video upload by Cfpp0

"4/8/25 (octaves overlay) SWTPC Psych-Tone + ADR Pan Scan + Eventide H3000B

Do people still have stereos at home, with two speakers? The SWTPC Psych-Tone synthesizer is running through the ADR Pan Scan, and its stereo outputs are hard-panned on the Mackie Onyx 1640 mixer. The Eventide H3000B is on an auxiliary send, fed by both channels. The Pan Scan rate is close to, but not the same as, the rate of the Psych-Tone sequence, which creates the random feel of the automatic panning. The H3000B delay fills the center of the stereo field. I recorded the same sequence in three videos, each with a different range setting, and they are overlaid here."

Bokeh, By Otaku Sound


video upload by Matt Lowery

"Download Bokeh here: https://otakusound.gumroad.com/l/boke...

Bokeh is an esoteric and highly musical collection of samples in major keys that I've been working on for a while now. The gist: familiar instruments processed in unfamiliar ways. Worked and reworked until they sound like liquid late-afternoon sunshine.

Recorded through an extensive collection of outboard preamps, compressors, and EQ- these samples are ready to drop into sessions of any kind.

Bokeh is a robust collection of 1-3 minute Long Play sound beds and 5-10 second Short Play samples. Equally at home in the DAW or hardware sampler environment, it provides a solid foundation against which composers and songwriters can craft sweeping, ethereal compositions.
