Used by
Brother and Baby Lock home machines, and many other machines and programs that accept it.
What it keeps
Stitch positions, colour stops, a thread slot from the 64 colour Brother chart, small thumbnails, and with version 6 the exact colours and names as well.
What it can't hold
On the machine itself, anything beyond the Brother chart: its screen shows the nearest of those 64 colours.
What to watch for
Brother machines only have a few hoop sizes, and a design that overhangs the hoop usually will not load. Check the size before you transfer it.
Best for
Any Brother or Baby Lock machine. Hoopbench writes PES version 6, and version 1 if very old software needs it.
