BMIDI Virtual MIDI SDK

What is the BMIDI SDK?

BMIDI is a cross platform SDK for developers or manufacturers who want to add virtual MIDI ports to their application or driver.
It is used by many companies — from very small to very large — for quick and easy virtual port support in their software.

Details

Essentially, BMIDI provides a simple library which allows applications to expose one or more MIDI ports to other MIDI applications. Those other applications use the BMIDI ports as if they were external hardware MIDI ports.

BMIDI is not a loopback driver, because one endpoint is always private, i.e. in your application. This architecture ensures best performance. A BMIDI application uses the BMIDI API to add or remove ports, to query ports, and to send/receive data to/from ports. The same BMIDI API is used on Windows, macOS, iOS/iPadOS, and Linux/RaspberryPi.
