I just finished watching this video from start to finish. thanks for posting this!

I also watched the video of that guy from Dynamix giving his feedback and comparison to the Medeli, its all very interesting.

I think one thing we can all agree on is - Social media is everything these days - his video just like your tutorial videos are all "Social media"... you make claims and observations, and so does everyone else over social media platforms.

I want to give my feedback here as food for thought...

I understand alot of vendors (and not just Keyboard / synth companies) are always trying to "simplify" things by reducing buttons on devices. Because in some cases - alot of buttons comes across to some people as daunting or "complex"... But in all essence, there is a lot of basic staple arranger functionality that needs a dedicated physical button, it just cant be replaced by a menu configuration or a "soft button"...

I think about arranger keyboards and other technology like this: how much can you achieve before needing to read the manual or watch hours of tutorial videos? sure you need a manual to go beyond the surface and deep dive to get into the nuts and bolts, but for an arranger keyboard with a large colour touch screen it shouldn't really be necessary.

Here are some examples:

The method you showed of switching from Arranger mode to solo voice (full keyboard) mode is absolutely ridiculous. Can you imagine trying to do all that on the fly while performing?

Sometimes while the arranger is playing I like to press 1 button (accomp) which immediately turns off tracks 3-8 for the base and accomp so all you hear are the 2 drum tracks that keep looping. then press the button again to bring them all back in. From what I can see - the most efficient way (on the fly) this can be achieved with the EVENT is to use the sliders to mute the 6 channels?... perhaps you have a way of programming this in the menu, but again what's wrong with having a dedicated button for such a staple feature? other brands have these buttons for a reason...

Another thing - you showed that you can have a row of soft buttons on the bottom of the screen for basic arranger functions like variations, fills, intros end endings - when you are playing live and you are trying to hit fills or switch functions in time, the touch screen doesn't always read your input unless you press it perfectly... And then if its a miss - you have missed a fill-in or a que for the next variation screwing up your performance. this happens to me on some korg keyboards where you need to press the track on the touch screen that you want to mute, and unmute etc...

I must say this keyboard is one of the most menu driven systems I have ever seen on any keyboard, probably even more than on my BK9 - which is a nightmare (death by scroll wheel!!)

You address the page up page down issue by saying you can assign 2 of the 7 assignable function (soft) buttons to these features... Now I am sure than any person that buys this keyboard will immediately want to set that up before anything else... so really you need to sacrifice 2 of the assignable soft buttons straight away for a basic function that simply should be there in the OS... hopefully something that can easily be addressed with an OS update??

Audio latency. you addressed this by saying that audio requires processing power / memory etc... so why not give the machine the right power it needs then?

Yamaha dabbled with audio styles for a little while (fair enough it wasn't as deep as Ketron) but still - no issues there with latency whatsoever.

You then mentioned that you can essentially go levels below to be on par with other arranger keyboards by using Midi styles to remove latency (as opposed to the real and live styles)... Lets be honest - the main hook to these Ketron boards is the Sound quality which comes from your AUDIO styles! To have latency on your flagship audio styles and use the fallback of "we are comparing to midi" doesn't sit well... it needs to be done right!

You made a lot of claims about how Ketron is next next level above the competition etc - but really in terms of the usability / interface it is not really ahead by any means. It pains me even thinking about trying to use that machine in a live situation.
