When will Ketron start putting out new sounds for the VEGA? Other than the one Orchestral set and the Lebanese card, I am not aware of any more. Given that you have to open the keyboard to install the Lebanese card (instead of loading it from disk for the Orchestral sounds from Ketron) it is not practical to have more than one expansion card sound set. If you buy the Lebanese and pay a rip off price of $400 for it, you can't replace it unless you open the VEGA and put in another $200 sound expansion card.
The solution is for Ketron to have more choices of sounds available, or sell the Lebanese sounds on disk.
If this problem is not solved soon, I like many others, will sell the VEGA and buy a Korg PA-80 which has an Arabic/Turkish card that sells for $180 in a form you can plug in the keyboard without having to open it (take screws out like Vega). You can also sample sounds on the PA-80 as well.
