Frap Tools Magnolia, 8-voice analog thru-zero FM polyphonic synthesizer | Project update

video upload by Frap Tools

Click CC at the bottom of the player for subtitles.

"Magnolia will be an 8-voice analog through-zero FM synthesizer, which we built to create sounds from the modular world through a classic keyboard interface.

Waveshapers, wavefolders, and, most importantly, analog linear through-zero FM unlock every sound associated with the 'West Coast' synthesis world. But that's not all! Fat resonant filters and powerful analog oscillators allow more traditional subtractive synthesis sounds as well.

A vast and flexible modulation section encourages complex patches with the twist of a knob, but it is always easy to keep track of what's going on thanks to LEDs on every source and destination. An arpeggiator and a sequencer complement the machine.

We are announcing and showcasing two pre-production units. We aim to release the final version at the end of summer, and it will show some differences. It may have a more refined interface, it will feature digital effects, and some of the features currently under evaluation may disappear.

We've been working on it for the last year, and we're eager to show it to the world!"

Frap Tools to take on high-end keyboard synthesizer market with ‘West Coast’ MAGNOLIA making its public debut at SUPERBOOTH25

MEDOLLA, ITALY: Frap Tools, hitherto known as a manufacturer of Eurorack modules and accessories alongside professional audio compressors in the 500-Series format, is proud to venture into the world of high-end keyboard synthesizers with its introduction of MAGNOLIA — announced as an 8-VOICE ANALOG THRU-ZERO FM SYNTHESIZER built to unlock every sound associated with ‘West Coast’ modular synthesis through a classic keyboard interface — anchored around showcasing two pre-production units at SUPERBOOTH25, May 8-10, FEZ-Berlin, Germany…

As an 8-VOICE ANALOG THRU-ZERO FM SYNTHESIZER, MAGNOLIA unlocks every sound associated with the so-called ‘West Coast’ modular synthesis world with waveshapers, wavefolders, and, most importantly, analog linear TZFM (Through-Zero Frequency Modulation) Indeed, its intentions are made clear from the outset by the on point wording worked tastefully into its (initial) top panel design. No need to necessarily remain there, though, for fat resonant filters and powerful analogue oscillators also allow for more traditional subtractive synthesis sounds. And although a deep and flexible modulation section encourages complex patches with the push of a button and twist of a knob, switching modulations on and off with the TOGGLE function, it is always easy to keep track of what is going on thanks to the inclusion of LEDs (Light-Emitting Diodes) on every source and destination.

Digging deeper, MAGNOLIA features eight analogue voices with two oscillators — carrier and modulator — and 24 dB/oct resonant HIGH-PASS and LOW-PASS filters; the carrier oscillator has a through-zero core for precise, sideband-rich analogue FM (Frequency Modulation) sounds, so crystal-like pads to growling basses are available to all with the greatest of ease, while FM can be applied to the filters. Furthermore, sculpting sounds that have not been heard before on analogue polysynths are now perfectly possible, thanks to MAGNOLIA’s unique signal flow — think continuously variable waveform shapes and a wavefolder circuit per voice!

Those two oscillators are derived from Frap Tools’ BRENSO (https://frap.tools/products/brenso/), a Euroack module readily representing its creator’s primary analogue source of articulated waveforms whose degree of entanglement can be precisely set by the musician. MAGNOLIA’s Oscillator 1 is the ‘West Coast’ one with TZFM, wavefolder, and FLIP SYNC, while Oscillator 2 is the ‘East Coast’ one, with PWM (Pulse Width Modulation) and fine-tune. Whether wanting experimental FM sounds or punchy synth brass, they are always at anyone’s service. Speaking of Frap Tools’ unique modular soul, MAGNOLIA’s filter section is derived from CUNSA (https://frap.tools/products/cunsa/) — itself a quadruple analogue ping-able multimode resonant filter, saturator, mixer, and oscillator, no less!

Musically, MAGNOLIA sports a keyboard from fellow Italians FATAR, with polyphonic aftertouch capabilities for enhanced expressiveness, while a per-part ARPEGGIATOR and per-part 16-step SEQ (sequencer) serve to creatively complement the synthesizer still further. Features briefly worth drawing attention to here by way of ending on some more high notes include MAGNOLIA’s bi-timbral programs (with SINGLE, MORPH, DUAL, and SPLIT MODES); all-analogue signal path; three loop-able DAHDSR (DELAY, ATTACK, HOLD, DECAY, SUSTAIN, and RELEASE) envelopes; three digital LFOs (Low Frequency Oscillators); and 512 preset memory slots.

Anyone attending SUPERBOOTH25, May 8-10, FEZ-Berlin, Germany can get up close and personal with two MAGNOLIA pre-production units by swinging by Booth B049 there. Their creators will be showcasing them personally, eager to show the results of their hard work, while providing a passionate warm welcome. Frap Tools aim to release MAGNOLIA as a production product by the end of summer, albeit with some differences evident by then. The interface will likely be more refined, featuring digital effects, while some features currently under evaluation could conceivably be removed."

"1950s Vintage Gibson Clavioline w/Tube Amplifier / Speaker / Case & Tripod Stand
The Gibson Clavioline is a single manual mini-key piano attachment with a tube preamp and amplifier, made from about 1934-1965. The sound made famous in Telstar and in The Beatles' 'Baby I'm A Rich Man', it uses a basic square wave.

The original design was by Constant Martin in France, and many companies licensed it. Selmer were perhaps the most famous maker in the UK, but Jorgensen in Germany was another, and Gibson in the US. The common design feature was a metal-cased keyboard, complete with internal tube tone-forming circuitry. The case attached by metal sliders to rails that could be screwed to the underside of your piano keyboard - or you could use the Clavioline as a stand-alone instrument on a metal stand. There is a Set of rocker switches underneath the keyboard for tone choice. The tube amplifier and speaker are in a case, which the Clavioline keyboard folds into for transport.

Although the tone is quite variable, the sound is distinctive, and instantly recognizable, due mainly to the simple envelope employed - and maybe also to its monophonic nature, which somehow gave melodies a different feel from exactly the same line played on an organ. It may be the glitches which provide its charm. Gibson licensed the Clavioline design from Constant Martin and made the American Clavioline version in 1954. Al Kooper plays one on BS&T's first album, Child is Father to the Man, and I think the specific tune is 'Meagan's Gypsy Eyes.' Also used on 'Sweet Pea' by Tommy Roe, 'Just a Mirage', Tommy James, and Del Shannon's 'Runaway'. A really cool instrument, it's the big brother to the Clavioline used on 'Telstar'.

Good condition, functional but has issues. Powers up, although the power light on the amplifier does not light. Keys play, but seem to just play one pitch, with a variable pitch underneath, and a quavering quality. The tone switches do change the sound, volume control works, and the octave switch works.

Includes the tube amplifier / speaker, which forms the case that holds the Clavioline, the Clavioline keyboard, 3-legged tripod stand, and power cable with split-off multi-pin cable that powers the Clavioline. Also has the service manual (which appears to be original). And includes the expression knee-lever, which is integral to the sound of the Clavioline.

Full pictures are here, along with a video of the instrument being played:

DK Synergy II+ with MIDI + Kaypro 2 computer + manuals + pedal + all sound banks (upgraded & serviced)

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

via this listing

SN 01646 & 74313

"Digital Keyboards Inc. Synergy II+ synthesizer with MIDI and Kaypro II computer, original owner's manual and all other information about connecting and editing in PDF, all factory and Wendy Carlos sounds on board of the Kaypro, SD cartridge as an extra backup of the sound banks and to save your own sounds, sustain pedals and custom made hardcase available for sale. It's a complete system which you won't find anywhere else in the world at this moment.

Both the synthesizer and the Kaypro have been serviced. Dani Wilson (Hideaway Studios, UK) serviced the Kaypro computer and added two Gotek disk emulators pre-loaded with the SynHCS Host Editor and voice/cart library. The old power supply has been replaced by a modern SMPSU version. The synthesizer got a new psu too, has been recapped and the keyboard contacts were cleaned. The RS-232 SIA cable is also new. Both the service invoices are included as a proof of what's been done exactly. We didn't save money to bring this beauty set back to life.

The Synergy is a very much more powerful synth than many realize - having two complete sets of 16 stage loopable envelope generators per operator which morph between high and low velocity acting on 32 digital oscillators with a remarkable amount of fluid modulation control available all in 16-bit digital audio is just mind blowing for a design that came out of the mid 1970s.

If you want to go deep into the programming side of the synth you need the Kaypro II computer. The complex synth engine gives you the ability to build up sounds from the ground on. It's a joy to build rich pads and melancholic film music sounds. The new owner will receive a testing video with information how to edit sounds prior to the packing process.

Optically there are some signs of use, but the overall condition is very good. The black case of the synth has some scratches, small dents, some missing parts at the edges. The tolex has sings of use too. The upper plastic panel of the SD cartridge is missing and the cartridge itself is in used condition. The Kaypro has some small scratches on the metal case and keyboard. There is a custom made hardcase for the synth which has signs of use too. Please check all the photos and ask for more photos if something is not clear enough.

Both the units are set to 240v. The serial numbers are: 01646 (DK Synergy) and 74313 (Kaypro II)"

"Here we have an EDP (Electronic Dream Plant) WASP synthesizer. Conceived and born in UK (circa 1978). Totally original. Fully working and serviced. Ignore the imitations/remakes. This is the real deal.

Photos shown are PRE-SERVICE. KKGB have ordered a complete new set of knobs. These will be fitted after a thorough service has been done. Suffice to say, that the synth has been checked already and all functions are robust. There are some scratchy pots/swiches at the moment; that is to be expected. They will be dealt with......The WASP has been little used (only one owner from new). The plastic casing is intact. The external 'wall war'" works well. Available to ship world-wide in 5 days.

See attached video [above] to show how good this little gem is, as a twin-oscillator analogue synth. There is sample & hold....noise......glide.....and much more......."

"Jomox XBASE 888 Analog Drum Machine Synthesizer 2024 Serviced and Updated by Jurgen Michaelis at Jomox

Several months back I bought an 888 and sent it to Jurgen at Jomox to tune it up and essentially fortify it, fortunately Jurgen responded cause I believe he normally doesn't service the vintage and discontinued Jomox instruments, then after a busy few months I finally got the email that the 888 is ready, has been updated with every modern up to date hardware improvement available, all the presets restored back to factory etc and in Jurgen's words is good for the next decades. Also listed was a brand new internal battery, changing/updating the scanner firmware and new power supply. This is very likely the best Jomox XBASE 888 available currently.

Before I sent it to Jurgen, after having used mainly Elektron drum machines, I plugged the 888 in and was blown away by the boom, heaviness and power from the machine. There is no harder drum machine and kick drum in my opinion.

In my opinion the 888 is the coolest looking and sounding Jomox drum machine with the grey and red finish and its raw sounding samples etc.

I paid 1100 plus shipping for the XBASE 888 before shipping it to Jurgen, then paid to ship it to Jomox, then finally for the service of course and to ship it back, so asking price is very fair in the end."

We take a deep dive into Cherry Audio's new Chroma, a meticulous recreation of the legendary and elusive Rhodes Chroma. It was a polyphonic analog synthesizer that came with some unique features, notably the ability to reconfigure the signal path among its oscillators, filters, and VCAs, opening up a wider range of sound possibilities. Cherry Audio's version combines these features with a modern user interface that allows direct manipulation of the parameters (unlike the original with a single data slider), and adds a full-featured effects section. We go over the expansive feature set of this instrument, showing you how each feature works and how to use them to make your own sounds.

Roland Juno-106 Synthesizer Troubleshooting/Repair Quiet Voice

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2024

Today I'm investigating an issue with a Roland Juno-106. Voice #4 is a lot quieter than the others. And it's not a calibration issue. 99% certain it is NOT the brand new voice chips I put in as seen in a previous video. Troubleshooting will confirm that statement. So what else could it be? Maybe something EVERY 106 owner will want to be pro-active about mitigating?

This video is posted for general information about my experiences. Always observe safety working on electronics, and never tinker around inside power supplies without first unplugging the power cord. De-soldering components on the Juno-106 must be done VERY CAUTIOUSLY to avoid lifting very tiny delicate traces. If you're not sure about anything, there's no shame in taking your instrument to a qualified service technician.

BAF 2024: MEMS And Associates - Buchla Modules

video upload by sonicstate

"At NAMM 2024, Sonic State had the opportunity to speak with Mark of MEMS and Associates, a research group that specializes in reverse engineering Buchla synthesizers found in universities across the United States. Mark explains that they have gone coast-to-coast, collecting rare Buchlas and have successfully replicated the David Tudor mixer from Wesleyan University. They also showcase their 132 waveform synthesizer, a 1965 module that offers complex waveforms. Mark shares that they have gained access to these universities simply by asking, and have formed collaborations to continue their work. He also reveals that these remade Buchla modules will soon be available for purchase through the licensed partnership with Analog Haven and Buchla as they aim to democratize access to these instruments.

In addition to the impressive remakes, MEMS and Associates also exhibited the rare 242 Programmable Pulser module, which allows users to program three different rhythmic pulses through a patch matrix. MEMS and Associates' future plans include hosting workshops for students to build their own modules and complete their university systems. This approach not only provides a more hands-on experience but also creates service records for these modules, as Mark mentions the lack of schematics and the need to trace circuits by hand. Mark told us the aim is to preserve and provide accessibility to these historically significant Buchla synthesizers."
