"This listing is for a very rare and historic Yamaha GS-1 88-Key Keyboard Synthesizer w/ Voice library & Anvil Road Cases.
We are selling this keyboard on behalf of famed Keyboardist Russell Ferrante of The Yellow Jackets. Russell also used this keyboard while on tour with Joni Mitchell as evidenced by her name stenciled on the road cases!
You can see and hear this keyboard in action on youtube with Russell playing it live with Joni Mitchell, along with band mates Vinnie Calaiuta, Larry Klein and Michael Landau!
Search: 'Joni Mitchell, Vinnie Colaiuta, Mike Landau, Larry Klein,Russell Ferrante - live-You are so square'
WORKING CONDITION: Fair - Mostly works and sounds incredible. When a card is entered into the drive it takes a second for the sound to load in, which is probably normal. Certain cards give access to the full keyboard, whereas others may only allow half, we don't know if this is by design or a result of a faulty card.
The tremolo section is working nicely, however, the detune and vibrato sections don't appear to function properly. The knob on the far left next to the keyboard doesn't properly work either. This synth has been in storage for ages and has not been used or serviced in years. Some TLC and attention would be advised before counting on it for another Joni Mitchell tour! Otherwise, this synth still sounds great and is currently listed in fair working condition.
PHYSICAL CONDITION: Fair - There are some notable scuffs and minor chips in the wooden chassis. Mostly notably the back and sides of the synth have a tacky-like texture from sitting in a road case for years where the deteriorating foam melded with the finish. We cleaned the entire unit extensively but the finish will need to be refurbished in order to get rid of that tacky texture.
However, the top surface, keyboard, and control section are all clean with no sticky feeling. This is good. The pedals are slightly loose from the frame as well. In all, each key, button, and knob is intact and ready for action. Overall, the physical condition is fair."

Teenage Engineering OP1 Field // Sound Quality You Can Finally Trust?
video upload by Dexba
"Yes, no, overpriced toy, saviour of all the portable jams, we will probably never know (and to each their own opinion). I got one, I was sceptical, because I already had four original OP1 in the past, and I was always tempted more by the idea, rather than any particular characteristic other than the portability.
The sound quality on the previous iteration was risible, the output used to hiss like a cat, it lacked dimension, character (other than being toyish) and practicality.
OP1 Field changes almost everything: it now features control over the quality of the tape and some other parameters, different projects we can save and recall, and sound quality is now at least up to par the job of not sounding like the Casio common ancestor, the new Mother Reverb sounds like a reverb and the Spring has become useful! WOW, and I am not sarcastic.
I would have never imagined a jam on my huge speakers with the previous OP1, and now here I am, with one track of the new Dimension analogue-ish synth through the cow (yes!) and the other three tracks coming from Strings, with an increasing number of overdubbing, always through the Grid effect.
Yes, it still lacks some features (I am not talking about the Undo, but for example the possibility of recording on tape while recording the master: it would have been handy to push the overdubbing even further), and the maximum sample length is a bit... old school, but I am so happy I can finally welcome an instrument I won't sell out of frustration in a matter of weeks 🧡"

Swamp Flux The Biggest Foot: Nintendo Wii Balance Board to CV Eurorack Module
via Kickstarter
"The Biggest Foot converts wireless Bluetooth signals from the Nintendo Wii Balance Board into control voltages you can use in your Eurorack synthesizer.
The Biggest Foot can record and play back your motions at various speeds or be used live. Playback can be triggered manually or by a CV gate to the Reset input. The module is 10HP and working. Test units are being shown at Superbooth 23 and small synth meets in and around the Carolinas. It still has some bugs to work out, but they are minor enough that it's now time to ask 'would you buy this thing?'
I have spent almost a year researching and developing The Biggest Foot from concept to working prototype through generous Patreon support, but the sum of those donations is rather small compared to how much it costs to get a module manufactured at scale. Using Kickstarter, I'm hoping to launch not just a module, but a business too."
Behringer System 55 - First Test
video upload by O.Z. Hall
"The Behringer System 55 does not have any module called 'slew' or 'glide' or 'portamento'.
A 'slew limiter' is the circuit which creates the 'glide/portamento' effect on a synthesizer. It is basically a 6db/octave low pass filter capable of sub audio cutoff frequencies.
In this video with the Behringer System 55, I'm using the 'lowpass' eq in the 923 module as a slew limiter (glide/portamento effect)."
