Dan's got a herculean task if he thinks he's going to make a VSTi engine in an arranger. Look at how difficult that task proved for Lionstracs. The onboard ROM libraries of even most BOTL arrangers are so extensive, so well sampled, and most importantly, so WELL INTEGRATED they have so far defied software equivalency.

I think Dan's time would be better spent making the software arranger work seamlessly with current TOTL (or MOTL) WS's like the MotifXF, Kronos, etc., and forget about the task of providing a soundsource that honestly stands little chance of bettering even an S910 or BK-5.

I mean, if you want an arranger with that sound quality, you are going to BUY an S910 or BK-5, etc.!

What we are looking for with software arrangers is MUCH better than currently available. And the only place you are going to find that is in a good WS.

If Dan were to concentrate on translation tables between PA3X style sounds (and Tyros4, Ketron Audya, Roland G70/BK-7m etc.) and Kronos ROM sounds (or MotifXF, Fantom-G or Jupiter80) it would be a world-class product. But tie it to naff user soundfonts of underdeveloped VSTi's, it will only ever be an also-ran, IMHO.

Learn from Lionstracs, Dan! Use existing, well thought out sound sources, and leave the VSTi integration to only an add-on afterthought! The Ketron module success shows the way.
