CYBERYOGI =CO=Windler Posted January 31, 2016 Share Posted January 31, 2016 On eBay I saw a rare workstation keyboard Casio CTK-711EX, which looks like an even bulkier variant of the mythical CTK-1000 with additional LCD display, 232 ToneBank, 110 rhythms and 3.5'' diskette drive. May it be that this one was "the real thing" while CTK-1000 was only a cut down household variant? (See here for my info and hardware analysis of CTK-1000.) Here is a YouTube clip about the CTK-711EX: My CTK-1000 panel PCB contains a strange adapter like when the hardware was originally designed for something else. Perhaps it was the LCD based CTK-711EX. This would namely explain why the fairly complex sequencer and synth in CTK-1000 was made but not means of data storage. By the way, I found out the mysterious meaning of "IXA Sound Source". It's "Integrated Cross-Sound Architecture" (thanks Synrise for info), which IMO sounds more like an advertisement name without technical meaning and therefore likely soon was dropped by Casio. I just found the CTK-711EX service manual from 1998, and the main ICs do strongly differ (see CTK-1000 hardware analysis). Thus it is likely more the case design than technical similarity. 2 Quote Link to comment Share on other sites More sharing options...

XW-Addict Posted December 3, 2017 Share Posted December 3, 2017 Bulky indeed lots of wasted space but the design is good. Quote Link to comment Share on other sites More sharing options...
MitsuharuSan Posted June 15, 2018 Share Posted June 15, 2018 IIRC, CTKs 711ex and 811ex are "upgraded" versions of CTKs 601 and 611. I had a 601, it's a nice keyboard with some limited editable parameters. Nothing huge, but thanks to the synth section it's capable of doing interesting sounds. It's definitely different from the CTK-1000, though (I had both at the same time to compare), but I would say that they're both nice instruments. A friend of mine repaired a 711ex when I still had my 601 - which is in his hands now, by the way - and I remember that it had the same timbres and rhythms plus more, so it's probably the same sound generator with extra features. For instance, it had a sort of "wah lead" sound (I'm not sure what it was actually called) that the 601 didn't. 1 Quote Link to comment Share on other sites More sharing options...
Szo Posted February 9, 2022 Share Posted February 9, 2022 On CTK 711 EX the scheme of DSP effects were: 10 (REVERB 1, 2, 3; CHORUS; TREMOLO; PHASE SHIFTER; OR- GAN SPEAKER; ENHANCER; FLANGER; EQ LOUDNESS t correspond to the effects 00-09 found in Casio CTK 750 from 1994 (CTK 711 EX is from 1998) - except the older one had more - 16 in total - DELAY 1, DELAY 2, ANALOG DELAY, TAP DELAY, CHORUS REVERB, TREMOLO REVERB.
