Does anyone here besides the creator Jos Maas has an mp3 sample of music created using OMB that is as good as sample using Yammy PSR2000 ? thx.

Can I use a laptop and a cheapo CASIO like WK-3000 to build a homemade arranger ? How about the voices - is it something I can just buy online and download to the laptop and use it in the OMB ? How about delay issues when pressing the fill buttons (I guess using one of the laptop keys), etc ?
