I wonder if you may have the same problems I have had with my midi controller keyboard. It has the USB connector and worked beautifully for adding melodies to my BIAB songs as long as I used XP. When I got my new computer with Windows 7, then nothing worked right. I have never been able to sync the controller with BIAB even after downloading the latest drivers from the manufacturer. The tone always comes in a few ticks too late amd there is no way to adjust the latency with the VST synth as it it set automatically by the program. Was thinking of going back to using my regular keyboard by using this converter device but then I noticed that it did not say it would work for Win 7. It states specifically that it works for XP, Vista and ETC. but it did not state that it would work for Win 7. Has anyone had experience using this converter with WIN 7?
