First, thank you for your reply and sorry it took me a bit to write back. I listened to the Miroslav violin solo that you produced and the sound is very nice. Not being very good on the keyboard, I am somewhat limited as far as playing a piece. However, I am a composer, have a very creative mind, and want to go beyond my current boundaries. In addition to sound quality, which, from your writing, it seems that Miroslav could be quite as good as GPO, I am looking for ease of use, and if needed, being able to speak to someone from tech support who are as readily available to answer questions as BIAB people.
Also, I'd be using this in RealBand and/or Pro Tools, which I forgot to mention on my first note, and as such, are both GPO and Miroslav compatible with both DAWs?

To summarize:
Looking into GPO vs IK Miroslav, which:
1 - is more 'user friendly' (putting aside speed and convenience)
2 - offers good tech support
3 - is compatible with both RealBand and PT?

On the side, I know that Groove 3 has tutorial videos on SampleTank, which would be the player through which you load Miroslav's sounds. Are there tutorial videos on GPO?
