 A growing number of soft synths and effects are also compatible with MPE (such as Equator, UVI Falcon, and Sandman Pro), as well as a few hardware synths (such as Modal Electronics 002 and ARGON8, Futuresonus Parva, and Modor NF-1).In addition to the original 31.25 kbit/s current-loop transported on 5-pin DIN, other connectors have been used for the same electrical data, and transmission of MIDI streams in different forms over USB, IEEE 1394 a.k.a.FireWire, and Ethernet is now common.
