Pink Noystoise NT-04 drone/sequence synth

via this auction

You can find a demo of the Noystoise NT04 here.

"This NT-04 is one of ten handmade drone/sequence synths made by Noystoise in 2018. It has two oscillators, a low pass filter, simple decay envelope, and an eight step sequencer that can be sync'd with external devices such as a Korg SQ-1 or Eurorack modules.

It's a fun, weird, and sometimes downright squirrly little noise maker and to be honest I hate to part with it, but sometimes bills have to be paid.

This particular NT-04 is in excellent condition, never used outside the studio, and pretty much as close to brand new as a used item can get. That said, there is one issue that has been there since I received it, and that is that the yellow JOY button next to the pitch knob has a tendency to stick in the on position when released, but a light snap of the button when pressing and it will disengage it. This appears to be a quirk of the construction as it rubs slightly against the front panel when pressed. I mostly leave it in the on position anyway as the joystick only changes the pitch when one of the sequencer keys is touched at the same time.

gstormelecto XaVCF Oberheim OB-Xa Eurorack Filter Module

gstormelecto XaVCF Test Filter Circuit [Audio Only Demo]

Published on Feb 16, 2020 gstormelectro

"Audio and Video by G-Storm Electro c. 2020

I've been getting requests for demos of my upcoming XaVCF module.
It will be a eurorack adaptation of the OB-Xa filter.
More info at
You know this sound from Rush Tom Sawyer and Van Halen's album 1984.
While we're all eagerly awaiting the module prototype I thought
I would share a brief sampling from a mini-lab test circuit.
A more thorough overview of the module will happen when it gets built.
So be on the lookout for that one in the near future.

The XaVCF will sound pretty far out.
We're talking about full on intergalactic blast off here.
Headphones recommended. BUT!...
Watch your levels, thick resonant sweeps ahead!
Prepare for ignition...

0:00 Classic 2-Pole resonant drop sweep
0:16 4-Pole Resonant Riser
0:41 2-Pole pure self-oscillation sweep w/ tracking
0:56 ...add both VCOs back in, slow sweep through sweet spots
1:40 2-Pole pure self-oscillation musical sequence
2:05 1-Pole Bandpass LFO modulated

VCOs: 101-VCF, Pittsburgh Synthesizer Box
LFO: Batumi
Delay: Timefactor
Sequencing/Control: Beatstep Pro
No mastering, no eq, nor additional post-effects added."

"The XaVCF is a faithful adaptation of the OB-Xa filter in Eurorack with added features.

As with the original, the XaVCF has two filter circuits to choose from! The heart of both designs having each its own Alfa reissue AS3320 chip. The XaVCF has the original Modes: a 4-Pole standard Lowpass circuit, and a 2-Pole Lowpass derived from a State-Variable circuit. Additionally there are 1-Pole Bandpass and Lowpass modes not available on the original!

Both filter circuits on the XaVCF not only have musical self-oscillating resonance w/ CV control, but the frequency cutoff can be tracked V/Oct using the CV2 input jack. In this way the XaVCF can be used as a sine wave oscillator. Unlike some older classic filter designs, the XaVCF retains a lot of low end at higher resonance.

The XaVCF is drenched in that fat and creamy wall of sound you’ll not soon forget. Are you ready for the Xa experience?

* Two selectable filter circuit configuration Types: Type I-SVF 2-Pole Lowpass, and Type II 4-Pole Lowpass.
* Additional Modes: Type I 1-Pole Bandpass, Type II 1-Pole Lowpass
* Two voltage controlled input jacks for Frequency CUTOFF w/ signal attenuators. CV1 is an extended range input capable of providing some boost to weaker control signals. The CV2 input will track V/Oct when its pot is fully CW.
* A voltage controlled input jack for RESONANCE w/ a signal attenuator CV3.
* Two audio signal input jacks w/ individual attenuators. Above midpoint, these inputs can overdrive the filter from most Eurorack oscillators and audio sources. This is especially useful in Bandpass Mode to compensate its weaker audio output signal.

CUSTOM ROLAND MJX-70 with Blue Keys and Custom Graphics

via this auction

Update: you can see it featured in a video posted here.

"This synth is a serviced, repaired, customized JX8P.
It is in decent working order now.
Decent used condition - See photos
Photos are of the actual synth you will receive!
It originally was in very ugly cosmetic shape and used to be a 220v version. It is now 110-120v (US standard)
The internal power supply has been serviced and setup to operate on 110-120v (Unites States standard) and is a factory Roland power supply for US use.
The synth has new custom wrap with new graphics made to match with Roland's look/theme used from around 1986 thru the 1990's.
This will also match the graphics of the Retroakiv MPG70 Controller which, if you have one, can also be used with this synth.
The synth was missing 17 keys when I got it, all have been replaced and tested with brand new BLUE 3d printed keys.
The black keys are factory originals.
The 1/4 audio jacks on the back are brand new gold replacements and they all work but as in most JX8P's they don't fit right, this is
a problem I have seen in every JX8p I have encountered. My patch cords (cheap rubber hose type) plug in fine and work, but other patch cords might give you a little trouble.
The 2 pin Roland power jack on the back has been upgraded to the industry standard 3 pin IEC type, no more
hunting around for the 2 pin Roland power cord! This gives it a proper ground connection too by just simply plugging it in!

I have owned this one for 10 years now, I am selling it because I rarely use it and to raise money to add other gear to my studio..."

Rare Synare 3 Drum Synth Clone by

via this auction

"Rare Synare 3 'UFO' Drum Synth Clone by in lurid kelly green, a faithful recreation with super solid construction made in the Czech Republic. As used by Joy Division on She's Lost Control and Ultravox on Vienna, also commonly used in dub soundsystems.

Two tunable oscillators and a lowpass filter, capable of self resonance, one oscillator switchable to be a noise generator, one oscillator can be set to modulate the filter frequency for wild metallic FM sounds with high resonance settings. Can be triggered by hitting the pad with a drumstick or sending a trigger sound, with velocity (just send quieter or louder clicks), into the trigger input for more precise timing.

The foam drum pad is slightly dinged in places but everything works as new. Have fitted three foam feet to the base for more stable tabletop use."

If you like what I do and want to support my work, consider joining my crew on Patreon -

Here are the beautiful Felt Instruments -
You can find the WAV file fo this piece on my Patreon page -

Here are some patch notes:
- I've recorded Lekko and Janso from Felt Instruments into the Morphagene, Arbhar, Microcell, Mimeophon, and Magneto.
- The Morphagene is playing the recording back at half speed.
- Arbhar has pitch modulation on the playback so it plays it in jumps of octaves.
- Magneto is on Looper mode but also set to Shift mode so there's a change in pitch as well.
- Mimeophon is also looping the recording, but I mangled it a bit so there are hiccups in the sound every now and then.
- Microcell is set to Granular mode and I have the Noise Tools module modulating its position.
- I'm sending the flute first to LedRover from VoicAS for some extra warmth and crunch.
- The picture is of me with my father, and we used to drink Campari a lot together so that's this red liquid in the glasses."

#DoveAudio #Modular #Synth #Sequencer"


via this auction

"Tested and working good! I acquired this synth many years ago, it was in working condition but had issues that are now fixed + customized! When I got it, it had a bad voice, the end cheeks were chipped, cracked and ugly, and there was a small amount of rust at the very edges of the control panel. The ENTIRE voice board has been replaced with a BRAND NEW ONE! (NOS directly from Kawai US)! The end cheeks have been replaced with REAL WALNUT end cheeks! (So much nicer!) All they keys have been replaced with Gold and Silver 3D printed keys, buttons too! Even has a custom RED memory write button! The Silver vs Gold keys denote where the "split" is when you pay in split mode. This makes it easy to see the split while playing in split mode, even under live stage lighting conditions thus minimizing the mistake of playing a bad note by playing past the split point!"

Yamaha CS-30 Analogue Mono Synth Modular SN 3920

via this auction

"The Yamaha CS-30 is one of the most flexible analogue monosynths ever made.

Featuring elaborate routing and modulation capabilities, alongside multiple envelopes and a built-in step sequencer, this is a sound designers dream.

My CS-30 has a built in mod to clock the internal sequencer from an external source.Simply plug into the external input at the back of the synth and turn up the trigger and signal dials on the front of the synth.

The CS-30 is almost modular in sound.I would go as far as saying its modular with switches.

This particular example is in very good condition for it's age, and is fully working."

YAMAHA AN1x Analog Physical Modeling Synthesizer

via this auction

Kind of interesting side note is the AN1X was branded as an Analog Physical Modeling Synthesizer. You can see it on the top right. However, it did not feature physical modeling as the KORG Z1, Prophecy, Technics WSA1, and Yamaha's own VL synths. Back when physical modeling and virtual analog synths were new they were often referred to either physical or analog modeling synths. Somehow Yamaha mixed the two in the AN1X.

As for the oscilator modelling on the AN1X it featured 2 oscillators per voice: square/ sawtooth/ pulse width/ ring modulation/ noise/ FM/ variable wave-shapes (Edge - sine/triangle)/ Saw2/ Inner1-3/ slave(sub) osc on osc1

You'll notice the lack of any modeling of real world instruments - brass, bowed strings, plucked strings, etc... It is a great sounding synth and offers a bit more in the oscillator section than many other virtual analog synths.

Best Ambient Synth Shootout #80: Roland D-05 - Song 1

Published on Feb 16, 2020 Christian's Sonic Spaces

Roland D-05 on eBay | on Reverb | on Amazon

"This is the first song with the Roland D-05 Synth. It's a remake of the famous D-50 first released in 1987, a digital synth using the so called ‘Linear Arithmetic’ (LA) synthesis.

I used for the recording the following FX chain:
D-05 - Alesis Ampliton - Pigtronix Echolution 2 Deluxe - GFI System Specular Reverb 2. Depending on the recorded track some FX are deactivated

The signal went through a Presonus StudioLive 16.0.2 into the PCfor recording. To create the complete song I recorded consecutively several stereo tracks. The final song was then mastered with a bit EQ and compression on some tracks and some limiting on the master track.

Well, I decided to go back to the basics, but at the same time make something useful for the synth community and do a kind of competition (I like competitions;-). What's my best synth for ambient music :-)"
