Guys,
I have had Dan's vArranger for almost 2 years now and have used it without any issues on gigs. I use mine with Ketron's SD2 module. I also have used Yamaha and Roland styles and they are pretty nice with vArranger. My controller is a Roland A-Pro 800.

Dan has been outstanding as a provider of support and answering questions for his product. I have often said the big manufacturers should be just half as good as Dan in providing support and upgrades.

Deane
