"Beautiful and super rare Crumar Spirit, designed by Bob Moog in the early 80’s, only around 100 pieces produced. This unit works at 117V from factory, if you use it in Europe you should buy a voltage converter (around 50€ for a good one on Amazon) The working condition are very good, I never had a single problem with this synth from when I bought it, obviously you should consider that it’s a 40+ years old instrument and sometimes could need some knobs cleaning and standard maintenance. The aesthetic condition are very good for its age, as usual there are different signs of use here and there, please take a look at the pictures and don’t hesitate to ask for more, I’ve tried to point every cosmetic defect in my photos. After several bad experiences with customs, I will only ship to EU, UK and Switzerland. - NO SECOND CHANCE ON SUNDAY FOR THIS ITEM -"

NEW 2025 Optigan Disc - BIG BEAT & POLYRIMBA

video upload by optigandotcom

"https://www.quilterlabs.com/collectio...

BIG BEAT is the latest in our series of excavatons into the Optigan Archives in search of material that was left on the cutting room floor. The working title for this disc was “Motown 1 - Big Beat.” Previously only heard on the song “How Do You Feel?” by Optiganally Yours. The keyboard sound is also sourced from the Optigan Archives- we mixed several different solo trombone and trumpet scales to form a brass section. A version of this sound previously appeared on our Orchestron "Brass Ensemble" disc.
Special note: This groove was recorded at a slower tempo than usual, so turn your Optigan's Tempo knob down to achieve concert pitch."

NEW 2025 Panoptigon Disc - POLYRIMBA

video upload by optigandotcom

"Now available at https://www.quilterlabs.com/collectio...

POLYRIMBA is based on the 5-against-3 polyrhythm. The basic sound is the classic DX7 Marimba preset. Individual notes are steady pulses with accents in counts of 5 or 3. Holding down chords creates an ever-shifting series of syncopated rhythmic patterns. If you count these in 4/4, you'll perceive longer rhythmic cycles that won't repeat for 15 bars. Adding delay will create even more complex patterns. Also, try it with the Panoptigon’s hall reverb turned up, and the main volume knob turned all the way down, to get an interesting ambient pad sound.

POLYRIMBA can only be played on Panoptigon, and is not compatible with Optigan or Orchestron.

Sequential Prophet 10 REV4 and Rhodes Piano | ambient improvisation

video upload by MIDERA

"My family and I went on vacation this week and had a great time. Some things came up at work and frustratingly, I feel I wasn't entirely as present as I'd have liked to have been. Kind of ruined a lot of things for me, but, despite that we had fun.

My oldest daughter, as usual, wanted a stuffy. We went to a store and she decided she wanted to wait to get something at a different place (because she usually liked the stuffed animals there. So later that day we drove down and - to her dismay - the new stuffed animals there were for little kids. We asked how she could tell, but she said she could. She did not want them. But we didn't have time to go back to the other place (since this was a restaurant and we were going to be eating dinner and the other place would be closed). I drove back up afterwards, looking for any place that might sell something similar, but nowhere did. The next day we knew a snow storm was coming in, a huge one. So she was very sad that we wouldn't be able to go back - but I was proud of her for two reasons: 1) She was able to hold off getting something now for the hopes of something better. 2) She didn't just grab something at the second place, because she knew she didn't want those. And although she cried and was very sad, she did not get something there. I was proud of her for that.

The next morning, we decided to go out in the storm and we did end up getting that stuffy for her. I got her something extra too because I was proud of her for waiting.

As for this track - well, I'm trying to see - do I really need that SX-240? Just because it's pretty? Basically, I have found the Prophet 10 actually does sound almost identical to the SX-240. As cool/nice as it is, I can't just keep all this stuff. There's just too much stuff here and I can make the same or better stuff without some of these synths in my studio.

Using the S2 Wavetable card on the MIDI/80 to create some surreal backing tracks, complimented with the Orchestra-90 through some wild pedals."

"The MIDI/80 Tracker program got much more feature-complete in recent weeks! By now, it not only allows sequencing of drum patterns, but of arbitrary monophonic MIDI instrument tracks (e.g., for bass, melodies, arpeggios etc.) With 6 tracks, it is polyphonic and multi-timbral, and can now support creation of entire songs. Whereas the first Tracker only offered one pattern, the new Tracker 1.95 can now manage up to 26 individual patterns, named 'A' to 'Z'. The workflow allows for pattern copying, i.e., to enable a musician to quickly make variations to a pattern simply by copying it and modifying bit and pieces. Moreover, each pattern has it's own settings, like tempo, number of bars, and on a per-track-basis, MIDI channel, MIDI instrument, and MIDI velocity. Like in a traditional arpeggiator, a GATE DURATION parameter determines the duration of the notes. Gate Duration can be configured on a per-track-per-pattern-basis as well. Most importantly, the new Tracker now features a "Song Mode" which allows for pattern chaining! A song can have up to 64 (pattern) entries - it is simply denoted as a string of pattern designators (like "ABBACAB*", where "*" means loop the song, and "." ends it). Moreover, real-time tracking is not only supported via the TRS-80 keyboard, but also over a MIDI keyboard connected to the MIDI DIN IN socket of the MIDI/80 card. MIDI notes can be quantized in realtime. MIDI/80 project member "DOWNPOLY" is now using this enhanced Tracker and the new Song Mode of the program to create much more complex backing tracks for his stunning Orchestra Sound Card Live Performances. The Orchestra Organ program by George Phillips is used as the solo / lead instrument, and MIDI/80 + Tracker is doing the background tracks.

As usual, the updated software can be found on the Github and can be downloaded free of charge: https://github.com/lambdamikel/MIDI-80"

"A great example of one of the absolute classics: a late-model Synthex, checked and serviced ready for this auction. Being a low-volume production item, the Synthex went through a few revisions before Elka mistakenly gave up on it because of lack of commercial success. Originally without MIDI, this was first added as a rather awkward breakout box using a 15-pin computer interface. A later version had the MIDI sockets on a metal plate set in to the right of the computer interface, and the final version had the MIDI IN OUT and THRU fitted to the actual back panel of the synth, and did away with the 15-pin interface.

This is the version in the auction, serial number 1543 - a very late example, and arguably the best version of all. It's in really nice cosmetic condition: as usual, the large wooden end cheeks aren't perfect, but the panel and keys are beautiful. Serviced in early 2025 ready for this auction."

YAMAHA TQ5 FM TONE GENERATOR SN QN01016

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

via this listing

"The Yamaha TQ5 tone generator is a 4op FM synthesizer with 8 voices, 8 notes polyphony and the usual 8 algorithms. It belongs to the same family of the Yamaha DX11 and TX81Z but it also adds ten built-in effects including reverb, delay and distortion, sharing a lot with the V50 and EOS B200. The unit also includes a 8-track sequencer, which makes it a great all-in-one machine in a rather small package.

The TQ5 has 100 presets, plus another 100 patches in RAM and an optional RAM card containing an additional 100 slots. The built-in sequencer is capable of storing 999 bars of music (about 10,000 notes) that can be recorded in real time or step time from a master keyboard. It also has a function of dubious utility which shows the current time, date and day of the week after a minute of inactivity. It does however expand on the "easy edit" functionality first introduced with the TX81Z and DX11, letting you modify FM parameters with an analog-like approach.

The TQ5 sits in the middle of Yamaha's departure from the DX era: on one side it still retains full compatibility with the classic 4op FM technology while adding bits and pieces to make it sound better and easier to program, but on the other side it's a hard break with the hardware design and interface paradigms that made Yamaha famous during the 1980s.

Supposedly, the slanted design of the control panel should make it easy to operate when placed on the left side of the controlling keyboard. Yamaha suggest having it on top of a PF1500 electronic piano, which is probably the only place it was designed for, considering that every synthesizer made by Yamaha till 1988 had sliders on the left side of the top panel. It won't even fit on a KX76 MIDI keyboard which should be a better companion than an electronic piano.

Although no further information could be found, the TQ5 has apparently been designed (together with the YS200) by the German design firm Frog, which was also responsible of Apple's successful design language of the late 1980s but probably never really understood how a synthesizer works."

Patching Panda Blast & Hatz V3 | Killer kick and hi-hat modules for Eurorack

video upload by Tom Churchill

"This is the second of a pair of videos I’m making about drums in Eurorack. In this one, I’m looking at two great-sounding analogue drum modules from Patching Panda: the Blast kick drum and Hatz V3 hi-hats.

In this video, I give a detailed overview of both modules and walk through all their parameters, then I build a couple of jams to let you hear them in context. As usual, you should find a few ideas for things to try no matter which modules you’re using."

MiMa's cover of Tim Follin - Chronos

video upload by mima85

"This is my own arrangement of the theme music of Chronos, a video game made for the venerable ZX Spectrum in the early 80ies. This piece is one of the early tunes from the great Tim Follin, and the term "great" is well deserved here because the ZX Spectrum's speaker by itself was capable to do just boring, monophonic buzzes. Tim, with some very clever programming, managed by software mixing to squeeze five, I mean FIVE channels of polyphony from that thing. So yes, 'great' is very appropriate for Tim.

Nonetheless, the original song is still a mosquitoes orchestra, five channels of polyphony but always of buzzing sounds, which many people can rightly find irritating to listen to. But this means that there's ample room of sound and stylistic choices when doing a re-arrangement. And for me, which I usually stick with the original arrangement and style when doing covers because I don't feel creative enough to come with something of my own, this was a cool exercise of creativity. Who knows, perhaps this means that some time in the future I'll be finally able to make some original music by myself :-)

As usual this video is not exactely a live performance, because the audio comes from the fully finished song. For the video I play the various parts like if I would've beein playing them live, paying attention to all the details (sound changes, execution, etc...) for the most realistic effect.

By the way, if you find yourself puzzled watching the pads I play on the OB-8 in the upper right corner, because chords with higher notes are being played in a lower octave, it's because I have a split patch with a version of the pad with slow attack on the keyboard's left side, and another version with fast attack on the right side. And the left side's patch is transposed up an octave so it matches the other one. This made playing those parts easier. That's one of the details I was talking about before.

As I am, like Tim, a big fan of progressive rock, I chose to do my cover in that style. I hope you're gonna enjoy it. As always, feel free to comment :-)"

Hardware Jams Weekend Challenge - Cadmium [WIP], Periodic Table

"Maschine+

The tempo is the atomic mass of Cadmium, rounded off (112).

Cadmium metal has high toxicity.

Cadmium was used in NiCd batteries for decades until NiMH and Li-Ion batteries replaced them.

Cadmium is still used as a component of control rods in nuclear fission reactors and in CdS photocells for light sensors and modular vactrol circuits.

A cadmium-dependent carbonic anhydrase (enzyme) has been found in marine diatoms in place of the usual zinc version."

'Modulation' - Ambient Drones with Lyra-8, Digitakt, Big Sky | 59 Perlen

video upload by 59 Perlen

"This is the latest track of my current ambient drone series, created with Soma Lyra-8, Elektron Digitakt and Strymon Big Sky. I wanted to create a mood that sounds different than the usual Lyra stuff and not like a typical drone. I felt like I need something else in my liveset and here we go - Digitakt adds a simple pad sound to the rhythmic pattern of the Lyra. 'Modulation' is also the title track of my upcoming performance."

Kaona Introduces Sisyphus Granular Eurorack Module w/ 8 Original Filters

via Kaona

Google translated:

Sisyphus is organized around a granular engine and a palette of eight original filters. Its granular system allows several grains to coexist in a single stereo sound stream that combine with each other.

This filter is based on a global granular design of the sound: it is not a granular engine followed by a filter but a real integration of filtering in the process of establishing the grain. Each grain generated carries the filtering characteristics defined by the musician and will be combined with the other grains according to evolving and configurable patterns.

The filters have been the subject of a completely specific development and are not from the usual libraries: they will therefore have a specific color that we let you explore!

Filters
→ Lowpass
Attenuates high frequencies beyond the cutoff frequency. Filter at 12 dB/octave.

→ Highpass
Attenuates low frequencies below the cutoff frequency. Filters at 12 dB/octave.

→ Bandpass
Let a band of frequencies around the cutoff frequency pass. Filters at 12 dB/octave.

→ Notch
Widens around the cutoff frequency and lets the rest pass.

→ Peak
Boosts the band around the cutoff frequency, while letting the rest of the spectrum pass without cutting it drastically.

→ Comb
Creates a series of cancellations and resonances, based on an internal delay and feedback.

"Une séquence très simple pour tester un quantizer que je pense adopter.
Je n'ai eu que des problèmes techniques depuis que j'ai acheté des modules et un rack Series 500. Ça a commencé avec le boitier 500 qui ne passait même pas dans le rack et ça a continué module après module (même avec du neuf qui ne fonctionnait pas et que j'ai du échanger), jusqu'au ground loop hier sur les entrée DI qui empêche tout ! Bref j'aurais mieux fait de m'en tenir à mon setup habituel, plutôt que de me lancer dans le API 500. Alors afin de me calmer, je me suis mis sur le 2500 et j'en ai profité pour essayer un quantizer (le Shakmat Bard Quartet) avec une séquence toute simple. J'ai commencé la session avec un tempo bien rapide ( • 02.07.2025 Mos-Lab & Scrotum Lab - Th... ) et puis la séquence et le tempo se sont adoucis jusqu'à cette fin de session qui aurait pu encore continuer, continuer, continuer..."

I have had nothing but technical problems since I bought modules and a Series 500 rack. It started with the 500 box that did not even fit in the rack and it continued module after module (even with new ones that did not work and that I had to exchange), until the ground loop yesterday on the DI inputs that prevented everything! In short, I would have done better to stick to my usual setup, rather than launching into the API 500. So in order to calm down, I switched to the 2500 and took the opportunity to try a quantizer (the Shakmat Bard Quartet) with a very simple sequence.

NEW MODULE: TIME

video upload by LARIX ELEKTRO

LARIX ELEKTRO TIME, Eurorack module OVERVIEW

video upload by LARIX ELEKTRO

"New Eurorack module: Swiss knif of Time management, for GATE signals:
Trigger to Gate converter
Clock generator
Trigger delay
Ramp generator
Connector for the Shift-R module, to add Clock Division option.

Of course, as usual, with CV contrôle and a lot of I/O.

Module available now, here: www.larix-elektro.com"

WHAT'S THAT THING ?
In fact, it's simple: it convert a trigger signal (hm, any signals) into a gate signal with CV controle of the time.
With its many inputs and outputs, it's the perfect companion to your favorite ADSR envelope.

It's also a clock generator, a rampe generator, and even a clock divider with the Shift-R extension.

The GATE output is augmented by 2 other outputs: START and END, which generate (as their name suggests) a trig at the beginning of the gate and one at the end.
The END allows this module to be used as a Trig delay, or to trigger another envelope at the end of a note, for example.
The START's output trig is generated each time a trig is received as input, even if the GATE is still active as output. Perfect for retriggering an envelope (if the corresponding entry exists on your module, of course...).

The GATE can be forced to zero by an RST input. (Think of HiHat Open and Close for example)
The input trig and RST each have a push button.

Finally, a switch allows the module to be transformed into a clock generator.
The input triggers the clock, and the RST stops it.

An additional output, not so common for this type of module, provides a ramp for the duration of the GATE.
This gives you access to a voltage that increases throughout the duration of the GATE.
Useful as is, or to send to a waveshaper for example.

The RITOURNELLE Shift-R, adds 8 trigger outputs.
The Rampe value is converted into an 8-bit word.
This allows for clock-type signals at smaller divisions than the duration of the GATE (or the clock in LOOP mode)
A kind of clock divider.
