Carrizo Plain Superbloom 2023 (with original electronic soundtrack)

video upload by CatSynth TV

"Scenes from the 2023 wildflower superbloom in Carrizo Plain National Monument. The Carrizo Plain is a large enclosed plain in central California that features native grasses and spring wildflowers. The rains of late 2022 and early 2023 filled the sometimes-dry Soda Lake at the northern end of the plain and set the stage for a spectacular wildflower boom featuring many species and colors.

Metasonix - RK2 XS-VCA

video upload by SchneidersLaden

"Here is a quick look at the Metasonix RK2 XS-VCA module - a tube-based VCA module with that Metasonix DNA. At gentle, soft settings the module is able to behave like a pretty normal VCA with some tube distortion but with rising gain the clipping distortion gets more and more. Turn up the Feedback and all hell is breaking loose. Sounds great right!"

"The ultimate vacuum tube VCA which can be more, for instance a pre-amp with 30dB gain, an amplifier for stereo and signal-cancelling effects and/or an extreme distortion effect. It can be gentle with a moderate bit of tube distortion but on the other hand it can tenderize a piece of meat with its raw power.

At gentle, soft settings the module is able to behave like a pretty normal VCA with some tube distortion but with rising gain the clipping distortion gets more and more. Turn up the Feedback and all hell is breaking loose.

In Metasonix' own words: 'What does it sound like? Imagine a slightly tubby tube amplifier, suddenly turning into a screaming chainsaw. And flying around the room to break your sappy bleeps and bloops. A bulldozer on fire crushing your nads. Strange tentacles of doom rise up from the bottom of the ocean and slap your sister's asscrack.'
Nothing to add."

Metasonix R-54

via this auction

"This is an impossible module to find and it was just luck that I was able to get it so I’m selling it with great reluctance. It kicks ass. Blast and blast, it’s got power and intensity. Grab it before I change my mind.

It uses a triode-pentode in a unique Wien-bridge circuit, to provide clean sine-wave oscillation. Using a Vactrol, the pitch of the R-54 is sweepable from less than 20 Hz to more than 5 kHz, continuously, via front-panel control or a CV input. By adjusting the waveshape/resonance control, the sinewave signal produced by the R-54 can be trimmed to less than 10% THD (depending on operating pitch)---with NONE of the problems inherent in solid-state oscillators and sine waveshapers. Because the Wien bridge contains no piecewise sine shaper or amplitude-control circuit or component. The tube itself performs that job. So the distortion products are entirely low-order, unlike the "sine waves" that solid-state VCOs or samplers produce.

Turn up the overdrive control, and the oscillator output clips the output amplifier pentode tube, for a unique soft-clipped square-wave sound. The simplicity of the R-54 will fool you--its behavior is odd and radical, and it will take you months or years to fully explore all of its quirks.

Now for the special trick. Plug an audio signal into the audio input. Instantly, the R-54 transforms from a VCO into a bandpass resonant voltage-controlled filter, with the same range as in VCO operation -- 20 Hz to 5 kHz. Its behavior and sound are unique. Again, you will be kept busy for years exploring all of its strangeness.

And now, it's got two new tricks. A VCA CV input allows you to control the output level of the R-54 as well as the amount of clipping in the output tube. Plus, a HARSH switch introduces a feedback loop into the CV control. Turn up the output level and the R-54 does very strange things.

CV response: Hz/v. Use a suitable MIDI/CV interface, or use our R-60 interface to obtain perfect equal-tempered tuning every time. Maximum output signal, 12 v p-p. Power requirement: +-12v dc, approx 150 mA. (All specifications are approximate and may vary from sample to sample.) Tubes used: 19KG8, 6AK5.

WARNING THIS MODULE USES 400mA FOR START UP!"

"We travel south on US Highway 395 and California Highway 14 in the high desert from the vicinity of Small Lake to the entrance of Red Rock Canyon State Park. Here US 395 emerges onto a wide desert plane near the border between Inyo and Kern Counties. It then splits from the northern end of CA 14, which was once part of US 6.

Eurorack Ring Modulators

video upload by John Schussler

"Ring modulation, according to the interwebs, is basically AM modulation (amplitude modulation) that goes through the full cycle. In AM modulation, any frequency below zero simply stops the oscillator. With ring modulation, you're still modulating the amplitude, but when the signal goes below zero volts it inverts the oscillator signal rather than stopping it. This creates a variety of new harmonics.

But those aren't necessarily 'ringing' harmonics. The ring in the name comes from the fact that most ring modulators use a "ring" of 4 diodes one into the other to create the effect.

Here's a sampling of the modules I have at the moment, doing a basic comparison of how their timbres differ. And a few have extra features that I'll try to resist playing with for sake of a fair comparison, but will probably fail in the attempt.

Sequence: Stochastic IG. VCO: Dixie II+ square (carrier) and saw (modulator). Envelope: Zadar

Metasonix TM-2 Dual Vacuum Tube BandPass Filter& VCA SN TM2-54

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

via this auction

"Metasonix TM-2 Vacuum Tube Dual Bandpass Filter and VCA. These are rare and highly sought after. This one is SerNum 54. It is also the early gold version before Eric Barbour went to bright yellow. They are rare, some sell for ridiculous prices, this one is fairly priced.

This filter is very raw, It can growl, bark and squeal like a stuck pig. It has CV inputs for Filter and VCA, which means you can rock out with this interacting with your modular synth, or stick in an expression pedal for your guitar.

There are several videos of the TM-2 on Youtube (not mine if you want to hear it.

This one is in great shape, everything works and it has very low hours of use. I'm only selling it because I am downsizing and I'm not using it much. Time for someone else to have fun with it.

Metasonix R-53 Vacuum Tube Waveshaper

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

via this auction

"The R-53 is directly derived from our legendary TM-1 device.

It uses a 12AF6/BD6 remote-cutoff pentode and a 12AV7 dual triode. Waveshaping is provided by a vacuum-tube "pulser" circuit that spits irregular pulses onto the input waveform. They synchronize erratically with the input pitch (if a waveform with sharp transitions is used). Combined with true vacuum-tube circuit distortion, this can provide a vast range of complex, aggressive distortion effects, utterly unique in the world.

A basic ring-modulation function is also available in the unit--applying a carrier pitch from an external oscillator to the screen grid of the pentode, this allows making inharmonic sum-and-difference pitch sound effects, with a unique vacuum tube pentode sound."
