This is why MIDI Polysher was rebuilt from scratch and it is now available as 32/64-bit VST plug-in for both Windows and Mac OSX. However, musicians have shown interest for this plug-in which can be used in other VST DAWs. I have prepared a small & simple to use SDK with bindings for C/C++, Delphi, Java and C#.MIDI Polysher is a free VST plugin primarly designed for eaReckon BloXpander users (but it works with other compatible VST host software).īloXpander is now provided with its own full-featured MIDI filter and therefore, BloXpander users do not really need this plug-in anymore. 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 WINDOWS DRIVERThe driver is currently part of the rtpMIDI-driver network-MIDI driver and the loopMIDI virtual loopback MIDI cable. MIDI PATCHBAY SOFTWARE WINDOWS DRIVERSSince 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. 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.
