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 https://www.modulargrid.net/e/g-storm...
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...

"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?

FEATURES
* 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

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..."

"Legendary monosynth much sought after admired for its bass sounds and percussive tones...a real masterpiece by Ruben and Serge Fernandez. Described as the French Minimoog this is something to rival the more common sounds offering much more variety. There have been fewer than 200 hand made from '79 and this particular one is in superb condition. Kept in a smoke free studio its entire life anyone looking for something collectable and mint will appreciate this for years to come."
