Engineered to be an all-in-one controller solution, the Akai Professional MPK261 is a performance pad and keyboard controller that combines deep software integration, enhanced workflow, and core technologies from the iconic line of MPC workstations. Each member of Akai Pro's MPK series comes fully loaded with a comprehensive interface for manipulating virtual instruments, effect plugins, DAWs, and more. MPK261 features 61 semi-weighted keys with aftertouch, 8 assignable knobs, faders, and switches, 16 MPC-style pads with RGB feedback, and onboard transport buttons. Three banks expand the number of knobs, faders, and switches (up to 24 each), and four pad banks expand the number of pads (up to 64 total). Plus, MPK261 is optimized to interface directly with your Mac or PC with USB power and plug-and-play connectivity.

Virtual MIDI driver for Windows 7 up to Windows 10, 32 and 64 bit with the ability to dynamically create and destroy freely nameable MIDI-ports. The necessity for virtualMIDI came along when I implemented my -driver. Later I also used this driver when I created for people who only need simple loopback MIDI-ports. I had some pretty specific requirements: • Compatibility from Windows XP to Windows 10 • Both 32bit and 64bit operation • On-the-fly creation (and destruction) of freely nameable virtual MIDI-ports • Only one side of the ports was supposed to be visible to the public • The other side only visible via a private interface • Multi-client-capability 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. All of the people there suggested to use the DMusUart and the MPU401 sample as a starting-point. So that’s what I did and creating the actual driver had been not too hard after getting enough insights at the WDK-documentation.

Virtual MIDI Piano Keyboard 0.4 Virtual MIDI Piano Keyboard is a MIDI events generator and receiver.You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another.

Nevertheless all the stuff people had done prior to my attempts would not quite achieve what my requirement were. All of those other virtual MIDI miniport driver implementations actually developed simple static “loopback” MIDI-ports. Loopback meaning that both ends of this port would be public. 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). This was not satisfactory, so I looked some more and I found references to dynamic creation of sub-devices. But this was a hard nut to crack.

Finally I had been able to locate a guy who was doing something similar for a virtual soundcard-driver for digital-audio-broadcast. His insights have been invaluable. It still took quite some time to get everything going smoothly, but I finally succeeded in creating this driver. One problem remained: Since Microsoft introduced Vista, all drivers for 64bit need to be code-signed. 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: Only companies incorporated could apply for such a code-signing-certificate. Many people in the driver-development-community urged Microsoft to rectify this.
