I have prepared a small & simple to use SDK with bindings for C/C++, Delphi, Java and C#. If you have a music-application that needs to create its own freely named MIDI-devices on-the-fly – virtualMIDI is exactly the right tool. But it can be used for other tasks as well.
Midi patchbay software driver#
The driver is currently part of the rtpMIDI-driver network-MIDI driver and the loopMIDI virtual loopback MIDI cable.

Since that time it is also possible for individuals to get their own code-signing certificate to be able to run their drivers on the 64bit versions of Vista and Windows 7. And finally in May of 2010 it has been done. Many people in the driver-development-community urged Microsoft to rectify this. Only companies incorporated could apply for such a code-signing-certificate. Though the idea itself is pretty nifty – to know the specific company that the code running in the kernel comes from – it had a severe drawback:
One problem remained: Since Microsoft introduced Vista, all drivers for 64bit need to be code-signed. It still took quite some time to get everything going smoothly, but I finally succeeded in creating this driver. Finally I had been able to locate a guy who was doing something similar for a virtual soundcard-driver for digital-audio-broadcast. This was not satisfactory, so I looked some more and I found references to dynamic creation of sub-devices. Static meaning that the number of ports and their names would be fixed at install-time of the driver (via the inf-file of the driver). Loopback meaning that both ends of this port would be public. 8-in/8-out MIDI interface, patchbay, and merger with time code sync. Nevertheless all the stuff people had done prior to my attempts would not quite achieve what my requirement were.Īll of those other virtual MIDI miniport driver implementations actually developed simple static “loopback” MIDI-ports. So that’s what I did and creating the actual driver had been not too hard after getting enough insights at the WDK-documentation. Since I had been hanging around on the wdmaudiodev mailinglist for quite some time due to my interest in kernel-streaming, I had already read quite a bit on the topic over there.Īll of the people there suggested to use the DMusUart and the MPU401 sample as a starting-point.
The other side only visible via a private interface.Only one side of the ports was supposed to be visible to the public.It can use FLTK or GTKmm for the interface and take advantage. On-the-fly creation (and destruction) of freely nameable virtual MIDI-ports ALSA Patch Bay is a graphical patch bay for the ALSA sequencer API and the JACK audio API.This freeware tool is also used to monitor the status of. Compatibility from Windows XP to Windows 10 AL-88s are supplied ready to use, the actual linking is managed via the CopperLan Manager software.Later I also used this driver when I created loopMIDI for people who only need simple loopback MIDI-ports. The necessity for virtualMIDI came along when I implemented my rtpMIDI-driver.
