I am from Turkey. The reason i consider this option is because my wife needs a tablet. So it feels like 2in1. Ignore currency but lets make a calculation.
Korg Kross 2 is 4000 TRY
Korg Krome is 5000 TRY
Ipad 128 GB 2800 TRY + Impulse 49 1500 TRY + Ipad Connector 300 TRY = 4600 TRY
Pros of second way is Ipad can be used by my wife for her work.
Cons is you need to buy many apps for different kind of sounds. I am not sure if you can find sweet brass ,string sounds. I am obssessed with them.
Other option comes with many sounds but you cant surf internet with it.
Whatever i pick i need solid 5000 TRY in my pocket. But nice brainstorm going here,ive found answers to many questions that i wonder ,thanks to you guys. This comunity is awesome.
It makes sense to go the iPad route if that is going to offer the best vfm for your family needs, but there is a big BUT and that is the quality of the instrument voices you seek that are available via Apps.
BTW
A non Pro version of an iPad is old tech and I for one would suggest that this is not the best buy for the long term.
The new iPad Pro has a different connector so expect that the availability of Lightning connectors fitted to current standard iPads to drop off considerably in the not to distant future just as the old 30 pin has so if you do buy a standard iPad do buy a couple of each of the connection leads that you will need..
If you plan on storing music and images on an iPad then 128Gb is barely enough, remember what I wrote earlier, my 128Gb iPad is practically full.
If you are going top use it for your music then screen size become important, I do have an old 16Gb iPad with 9.7" screen and that is a bit small for any detailed work hence why I suggest a Pro version and ideally the larger the screen the better.
As far as Apps go there are a lot of Synth Apps, which for me can become boring and repetitive.
Music Studio is a pretty good App with a full range of instrument voices but alas not one of the Brass voices compares at all to those on my Kross 2.
Have a look at this
It is the best App that I have found so far and the Lite version is free there is a paid for version which includes far more Instruments.
The last thing that I suggest you do is to buy the hardware before you find the Apps that suit the music you wany to play.
Good luck.
