I don't think I ever knew these were made in Poland. This is the first post to mention it.
"This Junost-21 synthesizer is a vintage piece of equipment that is made in Poland. It comes in its original box and includes all manuals. The synthesizer has 37 keys and is a keyboard type with synth keys. It has a MIDI (DIN) Out port and two pedal inputs. The Junost-21 is an analog synthesizer that features a modulation wheel, arpeggiator, and built-in effects. It is a great addition to any collection of synthesizers or pro audio equipment. This synthesizer is in working condition and is sure to provide hours of musical enjoyment."
"Completely overhauled Crumar DS-2 synthesizer with its original owner's (in German) and service manual available! All potentiometers are been replaced by new ones, the volumes of the monophonic and polyphonic part are matched, it's recapped and serviced...
The DS2 is a fantastic synth to work with. It can be played polyphonic and/or monophonic, it has two LFOs which can be used at the same time, I like the modulation options where you can choose which LFO you use, it has two glide modes, a great filter, two ENVs and so on."
The following was sent in by Anastasia Chernysheva, a Ph.D. student at University of Illinois Urbana-Champaign.
"In 1979, Donald Buchla invited experimental composer and his friend, David Rosenboom to collaborate on the design of a new, keyboard instrument with digital sound generation and hybrid, computer-controlled, analog outputs. The result was the Touché, released in the spring of 1980.
Among particular traits of the instrument are: • flexibility in use – highly programmable, (64 programmable function parameters available), Touché offers a library of “instrument” structures that could be stored as “presets”; • responsiveness – a user of Touché would enjoy a broad ability to program multiple stimuli and response structures in performance; • non-linear waveshaping – Touché permits to produce an enormous range of sound with efficient means of control, i.e. using a small number of knobs
The guiding idea of the instrument design was to optimize it for live performance. The hybrid, digital-analog nature of Touché assumes the following. • On the digital side: a sound-generating engine produced a wide range of timbre of sound possibilities with non-linear wave shaping techniques. • On the analog side: a programmable analog circuit called Multiple Arbitrary Function Generator (MARF) enabled extensive control of all sound synthesis parameters.
Rosenboom’s recordings Future Travel (1981) and Daytime Viewing (1983) offer extensive exposure to some particular sound worlds created with the Touché. Other than being used for these recordings and in the recent release by Richard Smith a.k.a. Shusta Cults, (the current owner of Rosenboom’s Touché), the instrument barely may be heard in any other recording. Only 4 instruments exist today but just one of them is in the functional condition.
To learn more about the history and design of the instrument check out the lecture about Buchla Touché given at University of Illinois (2022). Technical parameters of the instrument may be found in the brochure for the instrument. Download the PDF here."

"Guest lecture at EMS Forum: Circuits and Fingers – Composer-Performer Convergence in Electronic Instrument Designs, Oct 5th
With the director of Experimental Music Studios – Eli Fieldsteel.
According to Kimberly S Beasley, "This [Sonic Six] has been in the possession of our Professor Emeritus Dr. William Schirmer as it was given to him by Hoskins. Hoskins' granddaughter Dorothy is also aware of the instrument. We also have a large collection of manuscripts of Hoskins.
There is also a mini-Moog we just refurbished in our recording studio."
"Purchased in Denver in 1979 and lived in the mountains since then. It was only moved twice. It is in working but finicky condition. Has not any restoration work done.
You get the keyboard and all this other stuff too!

"This video describes and demonstrates a novel synthesizer module I recently designed and built out of a "Speech Synthesis" Kit that was distributed to schools by Bell Labs in the 1960s. After walking through some basic background on the kit and how I adapted it, I demo the kinds of sounds this module makes."
