Hi Fran,

You mentioned "The SD1000 is not USB powered. Power adapter is supplied.".

Yes, the SD1000 comes with a power adapter with a plug mix of 4 interchangeable plugs for different countries. My SD1000 came with the old power supply which did not match the new plugs. Before AJ shipped me the new power supply replacement, I powered the SD1000 using USB 3.0 port of my laptops directly without any issues. I have since then powered the SD1000 using USB 3.0 port only. I use vArranger2 software with the SD1000, and I like its sounds in general.

There is a discussion thread about SD1000 USB power issue in Dan's vArranger discussion forum. Some SD1000 owners power their SD1000s with USB port, while the rest found that powering SD1000 through USB was impossible:
