Roland Jupiter 6 Polyphonic Analog Synthesizer: Serviced

"The legendary and highly coveted dark-horse of the big boi Roland polys—the Jupiter 6.
Mine is in amazing shape inside and out. Serviced by Foleytronics a few years ago. Everything works and sounds as it sold.
This one in particular has a unique provenance; it was sold at PI Music in Cleveland which is where treznor use to work. It's the place he mentions selling DX7s in the documentary "I Dream Of Wires". If you watch the video you will see the original PI music sticker on the back of the unit in good shape.
I love the Jupiter 6 more than the Jupiter 8 and have personally owned both. It's my favorite Roland poly and one of the only vintage polys to feature a multi-mode filter. The synth sounds raw, dark, and melancholic."

Red Roland SH-101 Monophonic Analog Synthesizer: Serviced

"Restored vintage red Roland SH-101. New power switch, recap and calibration. Power button was replaced a few years ago. If you touch it while the unit is on you'll hear pitch wobble. That said, unit is tuned and holds absolute pitch from F1-C6. The filter and amp envelopes are calibrated as well. Sounds incredible. Recently texted with C batteries, works great
Two things of note: I removed the dust covers on both units in the transpose and LFO section. Personal preference. The red unit has a unique mod wheel that was modified by the previous owner to have a very satisfying mechanical 'click' when out the mod stick up to trigger the LFO. I've owned and serviced over a dozen 101s and never encountered another like it."

Original SEM vs Behringer—Which Reigns Supreme?
video upload by Memetune Studio
"A basic comparison between a vintage Oberheim SEM and a Behringer 2-XM
The idea is to see if the VCO, VCF and envelopes sound and behave the same, or are there subtle differences that mean that I won't be selling my Four Voice any time soon 😉"
Moog Muse -nature sounds, woodwinds and pads

"A song that incorporates a some of the Muse's smoothness. Done almost entirely with the Muse, except for the crow call- which is the 3rd Wave."
This Looper Hits Differently. But Why?
video upload by Synthux Academy
"In this video, I’ll show how we designed Spotykach - a looping playground designed to feel alive, responsive, and intuitive. Gesture, response, light, and sound all come together to make looping more like playing an acoustic instrument than scrolling through menus.
