"One of the classic modules of all time, and in its original R.A. Moog incarnation, dating from January (or possibly November) 1969. This example has a 'Bypass' switch mod. This looks very much like a factory modification requested by the original buyer - the style of switch and the black Dymo label seem exactly what Moog would have used at the time. Bought by the current owner in 1999, with light use in a smoke-free home studio. Working well. At some time in the past this actual module was sent to Paul Schreiber to help him design the MOTM 940, and Paul calibrated it to self-oscillate correctly. Situated in the USA but light enough to send economically worldwide."

"Four classic mid-seventies modules: one 921A Oscillator Driver, and three 921B Oscillators. Complete with an International Power switchable power supply (now more commonly badged Power One) and a wiring harness / loom wired for five modules - the four 921s here, and a fifth module - until now, the 904 in the previous lot. ***This will need encasing***, and of course the modules will need to go in a simple case or an existing cabinet. In very nice cosmetic condition, and working well. Bought by the current owner in 2003, and since lightly used in a non-smoking home studio. The power supply has a standard IEC mains socket and fused switch with power light. The fuse will need to be changed if the voltage is switched from USA, where it is currently located."

Ultra-rare Waldeck 70s US Synth

"One of the rarest synths ever - this one is serial number 7 out of about 10 that were built. They were designed in the late 70s by Steven Waldeck, professor at the Art Institute of Chicago. Although there are so few of them there is a good deal of information gathered at the excellent matrixsynth site: https://www.matrixsynth.com/2016/05/more-info-on-vintage-waldeck.html?m=1 We had this example imported from the USA with the aim of having Dani at Hideaway do her magic - but sadly she has too many other projects on the go, and could give no idea of how many hours it would take - and how economically viable it would be. She did check it for electrical safety: 'If it was a 240V piece I'd say it would need some serious attention to detail and most definitely grounded - at 120V, I would say at the very least it should be checked over properly and some addition of sleeving/insulating sheet of the mains wiring on the transformer, fuse and switch terminals.' Bear that in mind along with Mark Verbos' honest appraisal of another example from the matrixsynth page, and consider it a fascinating project, inspired by the VCS3 but definitely not a VCS3. Good for sound effects and weirdness, but not accurately pitched notes. Dani's general verdict as it stands: 'This was clearly intended to be aimed more at making sound effects than to be used as a well calibrated and stable musical instrument - the whole thing is extremely drifty with very narrow usable control ranges on the oscillators - there is a fair amount that doesn't work but I still had some fun making some sort of recording with it to mark the occasion.' https://soundcloud.com/hideaway-studio/1978-waldeck-on-the-waldeck/s-2j3HAUd60BE (corrected URL!)"

Korg multi/poly CS-80 Style Brass

video upload by Alec Sea

"Noodling on a CS-80 inspired preset I made for the Korg multi/poly. Using my new Native Instruments Kontrol S61 mk III with poly aftertouch. The bass drone and the brass sound are from the multi/poly, percussion is from the wavestate and UAFX Golden in 224 Hall mode provides the reverb. The multi/poly has a pretty good reverb, but this sound needs a Lexicon-style reverb. I used Arturia's CS-80 V as a reference, since I sadly don't have access to a real CS-80!"

03-The Casio Casiotone 405- Delayed Vibrato

video upload by AutomaticGainsay

"Here is a video that demonstrates the effects of the delayed vibrato function on the timbres and amplitudes of the tones (presets) found on the Casio Casiotone 405.

The theme of this series was made with the Casio Casiotone 405 and drums from GarageBand."
