zdubair Posted December 7, 2016 Share Posted December 7, 2016 Hello I am trying to find out if WK7600 and CTK6250 use the same sound synthesis and if the sound output is of equal quality in both keyboards. I have asked around and the anwers are confusing - some say both keyboards have the same AHL synthesises but some say the WK7600 har superior sound quality using a more complex synthesises... So i am hoping someone here could clarify this subject... Greetings Zdubair Quote Link to comment Share on other sites More sharing options...
Vorbis Posted December 8, 2016 Share Posted December 8, 2016 Here is a specification sheet that details the differences between CTK6250 and the WK7600 keyboards. There are significant differences between those keyboards. You will need to decide which features are important for you. The CTK6250 and the WK7600 are newer versions of the CTK6000/ WK7500 with just a few added features on each.

So i am hoping someone here could clarify this subject... Greetings Zdubair The WK-7600 uses tri-element AHL while the CTK-6250 uses dual element AHL. In terms of what this technical difference means for a user is higher polyphony (notes plated at once -- 64 on the WK vs 48 on the CTK) - and also the drawbar organ sim on the WK. If you plan on doing a lot of multitrack sequencing, having a higher polyphony count is very important. Likewise, if you use a lot of rock organ in your music, the WK is a better choice. Having 76 keys on the WK is nice, but if you only want/need 61 but want the better engine, note the CTK-7200 is identical to the WK-7600 except for the number of keys. Lastly, you were asking about the "synthesis" and sound quality, I may be wrong on this but I believe they are the same on the 6250 and 7600 -- again the real difference comes down to polyphony and the organ sim. This is just a gut feeling as I have played both models and the sound quality sounds the same on both. Quote Link to comment Share on other sites More sharing options...

Scott, My understanding of AHL elements is that the Tri-Element is composed of 3 individual samples to produce a higher tone resolution versus the Dual Element which would have 2 samples. I may be misunderstanding this altogether however. It would be nice to know exactly what that specification means.

zdubair Posted December 9, 2016 Author Share Posted December 9, 2016 Hm... well still a bit unclear - i also asked Casio directly but only got a referal to manuals. Here in Sweden the price difference between WK7600 and CTK6250 is not big at all (3800/3000) - i would prefer the CTK due to lack of space.

Brad Saucier Posted December 9, 2016 Share Posted December 9, 2016 You be the judge. 6250 - https://www.youtube.com/watch?v=RneDBMSbZ10 7600 - https://www.youtube.com/watch?v=3qfNln2Y0B4 Quote Link to comment Share on other sites More sharing options...
Vorbis Posted December 9, 2016 Share Posted December 9, 2016 Well this is how Casio describes AHL. http://www.casio-music.com/euro/glossary/ A AHL sound source AHL is the acronym for “Acoustic & Highly-compressed Large-waveform”, a technology for sound production developed by CASIO. This technology makes the realistic reproduction of acoustic instruments, especially piano sounds, possible. Quote Link to comment Share on other sites More sharing options...
zdubair Posted December 10, 2016 Author Share Posted December 10, 2016 Listening to videos and i can't hear any obvious difference between these keyboards. I think I will go for CTK 6250, Quote Link to comment Share on other sites More sharing options...

This may be true - but it also may only apply to the piano samples. I like Brad's suggestion: Listen to the demos and let your ear decide. :-) Quote Link to comment Share on other sites More sharing options...
