via this auction Circuit bent Speak & Spells and Speak & Maths are referred to Incators. Via suite101.com where you'll find additional info: "An incantor is the name given to a circuit-bent Speak and Spell or Speak and Math. The name was given by the incantor's inventor, Reed Ghazala. The name originally referred to instruments built by Ghazala, but the term has come to describe any Speak and Spell-type toy modified by circuit-bending. If you're unclear on what circuit-bending is, check out An Introduction to Circuit Bending. Because of their availability and ease of construction, incantors have proved to be one of the most popular circuit-bending projects. Even Mick Jagger has one."
via this auction "The synth has an added 25-pin connector on the left side, which does not affect any normal functions, and if you know how to use it it could come in handy. I do not know what it was used for by the previous owner. Because of this modification I am allowing returns"
Returns? I think that is the first time I've actually seen that on Ebay. Anyway, anyone have any ideas what the mod would be for?
Note this is the 3rd one to go up in the last two weeks. Interesting how relatively rare synths can come up in runs like that. I'm counting six total this year searching on Roland HS 60 here and on MATRIXSYNTH-B.
"As a happy owner of one of the amazing fullsize continuums, Jan Hinnerk Helms takes us through the possibilities and sounds of this handmade three-dimensional midi-controller in a workshop at Schneiders Buero.
"This demo i made in 2004 with audiotracks in Logic sequencer. Every sound is a audiotrack. All sounds drums fx etc. are pure from Yamaha TX7. No add of external FX, or dynamic FX. Delays i realized with midi, also pannings. Reverb with helb from right envelope programming. There are no layers in this track. Yamaha TX7 is the module of the legendary Yamaha DX7. 6OP FM synthesizer, no filter, no FX, no samples. This demo show only a little bit of 6OP-FM. If you take time for programming TX7 ... or an SY77 ... than you will listen much more interessting sounds. In this demo i not programmet the typically FM-Piano and this all 80s stuff. Listen more at http://www.deepsonic.ch" Update via fanwander in the comments: "The sound of the video is not made by the seller, but by Mischa Blättler from www.deepsonic.ch (See http://www.deepsonic.ch/deep/htm/synth_pure.php) Btw: does anyone know more about the Features of Version 1.4 versus Version 1.2?"
"The LCD is back-lit, unlike all the other ones you'll see today and most other days on eBay. It's also version 1.4 firmware. Not 1.2 and not the buggy 1.3 that replaced 1.2."
Note the TX7 is only editable via MIDI. More info on the display here.
