Glitchmachines Skein

video upload by Glitchmachines

"Skein is a FM synthesizer focused on experimental sound design and electronic music production.

Skein features 4 operators with skew controls and noise, as well as a flexible modulation matrix with per-cell modulation, per-operator feedback and eight user-definable algorithm presets. Key parameters can be targeted by numerous modulation sources such as 4 LFOs with 15 wave shapes, 4 modulation sequencers with various utilities and up to 32 steps, and 4 multi-mode envelopes. Easily shape and polish patches via two versatile multi-mode filters, as well as an effects processing chain that features 4 multi-effects with local randomizers and a reconfigurable chain order interface.

Much like our other creative audio plugins, we’ve taken an unconventional approach with Skein. Instead of replicating the classic digital FM synths of the past, we set out to create a new instrument that is primarily focused on sound design and sonic experimentation. With a multitude of powerful modulation sources and a variety of processors such as distortion, bit crusher, chorus, phaser, delay, reverb and buffer effects, Skein is capable of generating an incredibly diverse and expressive range of tones and timbres.

PM Foundations Harmonic Transformer

Harmonic Transformer Initial Fooling Around video upload by Randy Piscione

"PM Foundations Harmonic Transformer - Initial bit of fooling around with the independent characteristics of each harmonic. In this case, some of the harmonics fade in gradually, with various speeds and amounts of pitch modulation. The module can produce some interesting sounds that seem like acoustic instruments, maybe from another planet."

Harmonic Transformer Clarinet Test

video upload by Randy Piscione

"PM Foundations Harmonic Transformer - this video is a very initial test of reproducing the timbre of a real instrument, in this case a clarinet. I didn't spend any time on the envelope, only the timbre, and the playing is certainly rough. A full demo will follow shortly.

This was the video I used as a comparison:"

"Utah Symphony Principal Clarinet Tad Calcara plays the "Ode to Joy" melody to demonstrate the timbre of the clarinet."

Metasonix Penile Amputator vs. X0XB0X

video upload by fishjaco

"An 'uncut' 17 min take of messing around with the new Metasonix box for you to suffer through. Sorry not sorry. XOXO"

via Metasonix

"What is it? It’s a bad thing. Tube distortion pushed too damn far.

It’s the SMALLEST product we have ever made. Shirt pocket size. Inside is a preamp with feedback controls, using two 5702 subminiature pentodes.They are real Raytheon military surplus from the 1980s, not Soviet leftovers. The quality is aces.

ONE knob. The knob controls the feedback and gain. Fully CCW is off. Turn it up about 10% and you get increasingly LOUD signal, sliding into heavy tube distortion. Keep going up and it bursts into VERY LOUD oscillation. That’s the “feature”.

The switch is the other “feature”. It applies feedback to the suppressor grid of the second tube. What does that mean? We don’t know, we’ve never done this before and neither has anyone else. It is “unique” but you get to decide if it is useful or not.

There is a CV input on the front, it basically turns the Amputator into a really awful voltage-controlled amplifier (VCA). Ideally you shouod put at least 0-10 volts into this input. Can’t damage anything because it’s an all-tube circuit and there are no transistors or chips. The output is NOT able to drive “any load” so only feed it into a HIGH impedance unbalanced input.

It’s in a transparent polycarbonate enclosure because we STILL get stupid attacks from fools claiming that there are either no tubes in our products, or else the tubes do nothing and it’s all done with a “ten cent chip”. Fuck you, buttboys.

Here’s the damn photo. No, it does not have a 'bypass switch'. It’s on all the time because you deserve it.

Power required is 12 volts dc, 2.1mm barrel plug, center positive. 700 milliamps on startup and 250 milliamps in normal operation. NOTE: the standard version includes an AC power adapter for 100v-120v countries ONLY. If you are in a 220v-240v country, a “universal” power adapter is available for $20 more. Sorry kids: inflation and supply problems.

Everything sucks. That’s why each Amputator has different offensive stickers on it.

Video demos with drum machines: one, two.

I would put insults of guitar players here, but it’s pointless, they won’t read it. Some of them can’t read at all. Did I ever tell you about my ongoing battle with the IRS over my 2023 estimated tax payments? It’s an ugly little story and most people don’t believe the IRS is that incompetent. Well, they are.

Size: no idea. Small. Weight: a few ounces.

Any more stupid questions?"

X1L3 - YM 300 - Sanxion 🕹📺 - YM2149F - eurorack module

video upload by X1L3

"Brave attempt at the Sanxion loader music from the C64 by Rob Hubbard.

Chip used - YM2149F.....

Lots of modulator abuse and tracking to get it where it is. I even almost managed to nail the DJ record scratch just before the chill melodic part kicks in 🤣

YM 300, a 4XVCF and a 4XVCA set up for amplitude control, additional filtering and mixing of the three sound channels. The filters give the AY/YM an almost SID character. Especially when you sweep them on a channel with the on chip modulator active.

Very tricky one to cover on the YM due to the limited sound palette of the chip. It's incredibly hard to do anything with a long melodic structure without it sounding square wave basic, as is the vanilla nature of the chip. With the filters and some creative use of the modulator tracking things you can work around this. Without the additional filters this would have been impossible to do without it sounding too cute or like a dogs dinner.

The set up with filters is basically how an Atari ST or ZX spectrum might have sounded back in the day if their sound chips had filters.

Not a bad attempt. Not as neat as the C64 original. As close as i could get for a bit of fun with what i'm using. If only the AY and YM could do PWM 🙂"

Hexaphonic Witchcraft Synth by Ekkoflok Electronik

The Hexaphonic:
Six fully tunable oscillators
Touch controlled
Stereo panning
Amplitude
100% weird starve control for chaotic sounds

via Ekkoflok Electronik

"Introducing the Hexaphonic

A synthesizer, a choir of six oscillators joyfully singing along or against each other, producing an output spanning from harmony to cacophony, all by the touch of your skin.

'Hex' is the greek word for "six" and close to the Danish word "heks", which means "witch". It is about time we throw some witchcraft in our electronics and honour the wise women of the past and the present.

Electronic engineering is in many ways rather conservative, but fortunately there are cracks in the surface - like sticking your fingers inside a circuit or "starving" a circuit to intentionally prevent it from operating predictably. HEX is such a circuit - you play it by extending the circuit with your fingertips (or other conductive matter), and force it into chaos by cranking the "starve-control". Let the circuits starve and spare the abundance for the Humans in need.

Like human beings HEX is a mood swinger of sorts; it's mood changes rapidly from harmony to chaos - blindly obeying the orders of the starve control. If the electrodes are the limbs of HEX, the starve-control is the brain - or maybe rather a parasite of sorts, taking control of an otherwise well-behaving instrument. Luckily it seems that HEX is perfectly happy with returning back to a normal state again after a trip into chaotic territory; thereby reducing the starve-control to a humble way of controlling the timbre - it's not a filter, nor a wave-folder, but it surely does alter the timbre in a non-linear and most importantly pleasing manner.

Starving circuits is not a new thing; it has been exploited in fields of circuit bending for ages, and interestingly it is also a well-known trick among guitarists to emulate the sound of a fuzz pedal with a dying battery - by limiting the current flowing from the battery. However it is not something you see on the front panel on the average Behringer synthesizer (yet?!).

Please note that 'PCB only' means that you are buying a bare circuit board and have to source the components for yourself."

Oscitrode Synthesizer by Ekkoflok Electronik

The Oscitrode says hi from National Center of Contemporary Art in Moscow

From Oscitrode workshop in the National Center of Contemporary Art in Moscow (NCCA).
Second of March 2019"

via Ekkoflok Electronik

"Introducing the Oscitrode
A synthesizer controlled by your skin and breath.
You extend the circuit by letting the current flow through you and the circuit extends you by turning the physical contact into sounds yielding from simple oscillations to complex and chaotic patterns.

Six analog oscillators controlled by and interacted with through twelve electrodes.
A "starve" control known from the world of circuit bending serves the mean of varying timbre and modulation in a nonlinear and chaotic way.

The electrodes are made of bare non-tinned copper and will probably change colour (and conductivity) over time adding a final time dependant layer of complexity to the circuit."
