I am a former demo guy for Ketron & produced a video owners manual, so I am familiar & a little partial to Ketron. One of the reasons is that navigation is easier than the big 3 or 4 manufacturers in my opinion.
Let's also keep in mind that if you compare all arranger products over the last 10 years, General Music has always been out in front with innovation. Big Screens, Notation, Sampling & Wav Sync were features back in 1996 .
That being said, I think many people have this impression that Ketron has poor navigation and editing is lacking . But it's not. Editing of styles or midi sequences is extremely easy and how Ketron utilizes the hard drive is different than most companies.
When you buy any Ketron product and take it out of the box & you listen to a style play , press 1 button and the screen changes so that you can view the sounds & volumne levels with the press of one button . You can change sounds & levels in real time. If your happy with the changes, you press save enter and one more button (F2) and the keyboard will save your changes ,without saving to a registration. Kind of an instant snap shot of your style preferences.
Editing sound & volume levels is easy with Midi Sequence playback as well.If you copy a midi file to the hard drive, you can play that midi directly from the hard drive and change sound and volume levels and save your changes, without losing the original midi sequence and save on the hard drive.
In regards to audio loops with Ketron products. It was easy to sync drums (SD1) , because drums do not respond to chord progressions. The thinking is audio produces the best playback of real instruments.
With Audya, they are using midi as the map to change multiple audio loops in real time , which is not currently done on any arranger keyboard.
Midi is numbers vs. audio is realistic. Sampling a guy or girl playing guitar is better than using numbers to create that strum....It's getting the multiple samples at the same time, change in real time. That is the trick. Answer ? Use midi to manipulate audio. Hence, Audya !
I hope what I'm saying makes sense.
