are any other plug-ing possible to work with ak or these 3 only?

Tomic - I'm not sure what you are referring to here. Which 3 plug-ins?

Tomic,
 
They just released Electric Grand, which can be added to these three...

This is not a sampler, it's a Keyboard VI...and only XLN Audio sells the modules for this..

So, you can't use third party "plugins" within AK...

thanks,cclarry,that is exactly what i wanted to know

i tryed to use yamaha clp 470 with AK,that is not working,may be i missed something,help needed

Tomic,

Since there are no specifics...here are some possibilities...
 
It appears that the Yamaha only supports USB recording and DATA transfer...not MIDI via USB.
If that is the case, then you can't use the Yamaha as a controller for use
with AK via USB...

If you are using the MIDI interface on the Yamaha, and a MIDI interface to get the
MIDI to the computer, then make sure you have the device set up in the "Audio and MIDI" settings,
which is in the upper left hand corner of the interface..on AK...

Don't know if that helps...

cclarry,many thanks,and you are right.....Not only do we make the music...  
the music makes us...    

cclary,
Fate is playing with us,and we are playing a pipe!
your turn now
 

I've seen and heard nothing but great stuff about Addictive Keys.
 
For $29 (apparently on special from $179) it's too good to resist.  Helps me avoid paying $300 for one of the Ivory packages.  I just want a couple good sounding pianos and this appears to fill the ticket for what I've needed.
