Farfisa Polychrome – A short demonstration

video upload by melodikakofoniko

"Farfisa Polychrome – A short demonstration (with added reverb).

My rarest (and most awesome) synth must be the Farfisa Polychrome. It's a thoroughly beautiful Italian string machine from the late 1970s with four independent sections, a BBD chorus, and a great phaser effect. It's kind of similar to the ARP Quadra (but without a mono section—everything here is purely divide-down based). It's similar in size to the Korg Trident or Elka Synthex (HUGE!) but even heavier! It's got a really otherworldly analog vocal chorus section that sounds unique and beautiful, especially when combined with the other sections.

The keybed has a really nice mechanical aftertouch mechanism, similar in construction to the one found in the Yamaha CS series (though this one works with a magnet and a Hall sensor). My Farfisa collection also includes the Soundmaker and the Synthorchestra—Farfisa's earlier but similarly unique and cool machines with a distinctive 1970s sound (compared to the Polychrome, which sounds quite different)."

Moog Micromoog & Modular w/ AJH/MiniMod, Hermod+ analog synth jam

video upload by DreamsOfWires

"Testing my faulty Micromoog with some helpful modules from AJH Synth: My poor old Moog isn't scaling/tracking correctly, so the V-Scale module is being used to modify the 1V/Oct output of the sequencer to produce the correct notes. Video guide to how this was achieved: • Correcting Vintage Synths with V-SCALE - T... [below]

Normally the Micromoog follows a 0.95V/Oct voltage to pitch scale, but mine can no longer even be calibrated to this with it's internal trimmers, so until it can be serviced (probably with some new components), the V-Scale at least makes it useable with external controllers and sequencers.

Sequenced by the Squarp Hermod+, the synth's faulty tracking is then corrected using AJH Synth's V-Scale module, gates coverted by the AMSynths AM997 Gate to S-Trig converter.

Micromoog filter modulated by AJH Tap Tempo VC-LFO, random gate skip by AJH CHance Delay.

Drone is 3 AJH MiniMod VCOs into Matrix VCF.

Mixed in the Cosmotronic Cosmix Pro, reverb from FX Aid, delay from 2HP DLY, final mix recorded on the Disting Mk4."

Correcting Vintage Synths with V-SCALE - Tackling Tracking & Tuning Problems #ajhsynth

video upload by AJH Synth Official

"Using V-SCALE to compensate for the tuning/tracking problems on one of my Vintage Synthesizers, this time a Moog Micromoog from the late 70's. Also, showing how PRECISION VOLTAGES can also be helpful, and bringing the TAP TEMPO VC-LFO, CHANCE DELAY, and the MATRIX VCF into a short performance demo - FULL performance video by ‪@DreamsOfWires‬ can be found here: • Moog Micromoog & Modular w/ AJH/MiniMod, H... [above]

V-SCALE at its simplest will function as a highly accurate buffered multiple, but four of its five outputs are adjustable by way of multi-turn trimmers. These allow for very gradual adjustments to outgoing CV signals, so that they can be made viable for synths or VCOs that are not scaling properly.

Here I'm adjusting/modifying a 1V/Oct signal from a sequencer so that it controls my old Micromoog correctly, but it could also be used with incoming signals other than 1V/Oct, or even to correct am incoming signal which itself isn't scaling correctly or as desired. Each trimmer has an adjustment range of +/- 5%.

My Micromoog's tracking is so far off that it cannot even be corrected using the internal trimmers on the synth, so I'm using the Keyboard Output (KBD) as the CV input, instead. of the intended OSC input. This method bypasses the keyboard, so the keyboard voltage isn't added to incoming control voltages, and so doesn't interfere with it. The only drawback is that the root key will have to be changed to match the notes on a keyboard. That's where the PRECISION VOLTAGES comes in - it can accurately offset an incoming control voltage by semitones and octaves, either up or down."

"We’ve decided to sell our Metasonix D-1000, one of the rarest, most sought after and possibly weirdest drum machines ever. It’s estimated that only around 150 of these were produced.

'Unleash pure sonic chaos and analog character with the Metasonix D-1000—an unapologetically wild drum machine that ditches sterile digital precision for raw, tube-driven power; built around real vacuum tube circuitry, it delivers aggressive, unpredictable tones that range from deep, thunderous kicks to searing industrial textures, making every beat feel alive and dangerous; whether you’re crafting experimental electronic music or looking to inject gritty personality into your productions, the D-1000 doesn’t just make rhythms—it creates an experience that’s bold, tactile, and impossible to replicate with anything else.'

Tested and working fine - noisy and weird, just like it was meant to be."

Yamaha DX7 w Grey Matter E! Serviced Digital FM Synthesizer

Additional Tone Tweakers Listings

"This dx7 is a 2FD with E! expansion. The E! expansion expands its internal memory, makes the IIFD 8 part multi-timbral and adds a sequencer. If this one doesn't sell soon, we'll probably keep it.

Our tech spent around 6 hours servicing this unit. In addition to any necessary repairs, he replaced all the tact switches with new ones so they activate with a light touch, replaced the battery, cleaned things inside and out, and may have done some other work as well (I don't have access to his notes at the moment but will try to update this listing later). This unit was systematically tested, works as it should and sounds fantastic.

As you should be able to see from the photos, the backlight is very bright, but as is common with this model at this point in time, the contrast isnt as strong as it originally was. Regardless, the display can still be read easily. We could probably install a new one, but this would up the price considerably and there would be a wait."

Korg Minilogue meets vintage Oberheim OB-8

video upload by Synthnerd

"I recently restored an Oberheim OB-8 for someone and before handing it back I decided to see how it compared with the diminutive Korg Minilogue. The Korg is new, small, and cheap – the OB-8 is none of those things. But how do they sound together?

The Minilogue is playing an arpeggio through a TC 2290P delay pedal. Both synths go into the Tascam Model 12 with nothing else in the way. Reverb is from a Lexicon MPX1, their mid-range unit from the 90s, which sat just below the PCM series and above the budget MPX and LXP models. No further processing on this, the audio is straight from the Tascam."

Designing a Module - Prototype itteration with Instruō

video upload by Instruō

"In 2015/16 Instruō began as a video project. Specifically a time-lapse of me designing the original troika module.
Ten years later, I’ve returned to that idea with ceithir, a winter holiday project I designed with video documentation in mind.

Before the first full sized (58HP quad) ceithir hardware prototype, I focussed on a single filter channel version. This video covers the second prototype iteration of this single channel version. It was a pretty significant revision from the first one, but paved the way for the quad design.
The filter core board was designed with this design, which remained almost fully unchanged in its final form (I changed one resistor value).
