This is the first post to feature the Zerosum Inertia Horripilation.

"6/14/25 (abhorrent) Roland System 100m + Metasonix R-54 + Zerosum Inertia Horripilation + Peavey 1300 + Alesis MIDIVERB II

Some sludgy Sample & Hold. Pamela’s New Workout clocks the Roland System 100m 150 module’s S&H, which sends its clock out to the 140 envelope and its S&H out to both 110 VCOs, both 110 VCFs. The 140 envelope controls both 110 VCAs. The 150 LFO and the 140 LFO also modulate the VCFs on the two 110 modules. The upper 110 runs through the Zerosum Inertia Horripilation module, which is also modulated by the 150 S&H. The lower 110 runs through the Metasonix R-54, modulated by the 150 S&H signal. The R-54 runs through the Peavey 1300 and is panned center. The Horripilation signal is panned a bit left. Both signals receive some room reverb from the Alesis MIDIVERB II."

GS Music Bree6 // Small Simple and Sublime

video upload by Starsky Carr

https://www.gsmusic.com/

"Sound is everything... and the GS MUSIC Bree6 doesn't fail to deliver. There's an intangible quality to the tone of their synths. The GS MUSIC e7 bing their first offering, that bowled me off my feet when I first got my hands on it.

This was first announced in NAMM 2024, so it's took a while to get to me - and it was worth the wait. Its a single VCO 6 voice polysynth with a 24dB LP filter and all analog signal path ... so it's in the same ball park as Juno's except this is a VCO, not a DCO, and has a different flavour.

Importantly for a boutique synth manufacturer, this feels great to use - its got a knob per function interface thats so intuitive and easy to navigate you'll be an expert in minutes!"

new, a sponge based audio oscillator

video upload by RS-Elc

"Sponge material shows an extremely large dielectric constant that changes with the amount of compression. It can be made into a wide range variable capacitor when clamped between two metal plates. Capacitors in the range of 100nF can be made with only a few cm of (cellulose based) sponge material.

This movie shows a sponge-based oscillator and a sponge-based lowpass filter as an introduction into 'Spongetronics'. Comes with oscilloscope waveforms and resulting sounds. More info on Elektor Labs."

Roland JX-10 Custom Ambient Sounds (read description)

video upload by LFOstore

"We explored the older brother of whole JX
series - mighty JX-10!

It's like 2 JX-8P's in one keyboard.

As you may know this model is kinda unfinished and originally having no sysex or midi implementation.

If battery will die you will lost all your sounds and the only way to restore them - is to buy original or retro cartridge.

here: https://www.ebay.com/itm/335389922310

If you having such a cartridge you can easily
save soundsets on the synth and on the computer.

Even without Vecoven upgrade.

While we are waiting the cartridge replica, this video showing that we already started to make our, soundset.

Enjoy!"

Startone MK400 review: $170 beginner's keyboard with HIDDEN features

video upload by Floyd Steinberg

"The Startone MK400 (aka Medeli MK401) is a 61 keys 64 voice 16 part multitimbral keyboard with long feature list, including a sampler. It can record MIDI and audio directly to SD card and send audio over USB to your DAW. It also has some undocumented but powerful features that I briefly show in this video. My review of the MK300 still is one of my most popular videos with over 100.000 views - the MK300 is a go-to keyboard for kids who want / are encouraged by their parents to learn the piano because of its note stand, a good sounding piano patch and a sustain pedal plug. The MK400 is built on the same ideas, but adds a lot of functionality, upping the price to $170, which still is an incredible bargain.
