Subject description: New midi-utility concept: table-driven midi integration, all pc input midified, easy mixing
Reply with quote  Mark this post and the followings unread

Introducing a radical new midi-utility concept: table-driven midi integration software for faster, flexible instrument building. All inputs on a PC can become midi inputs, as needed, with easy reconfiguration.

Midi Integrator 1.0 is fully tested and works as soon as unzipped on Win/Mac systems.

The online description can be found here: http://www.altkeyboards.com/integrator and you can download the Max/MSP source, executable and manual here: http://www.altkeyboards.com/file-cabinet. Midi Integrator is copyrighted and released under GPL3.

A few highlights of Integrator:

· Adds sustain, pitch-bend and modulation controls, via one or more touch-pads or a mouse, to any midi system with a Win/Mac PC .

· Can trigger any note, control command, pitch-bend, or preset action at the touch of a key;

- Converts your PC-keyboard into an auxiliary midi-input controller and keyboard.

· Works especially well with 2-dimensional instruments like the Axis-49 and -64.

· Enables features that are normally considered “high-end”, such as keyboard splitting (parts of a keyboard playing other instrumental sounds), key-modulation or octave-shifting at the touch of an assigned key.

· Extensible with a Max/MSP development system. For example, it can be made fully micro-tonal.

I discovered the need for a midi integration system when building my then-experimental jammer keyboard. I found that programming key-reassignment was an absolute pain, and so I made the configuration table-driven. This proved to be very significantly faster and much more convenient.

Then, I envisioned a host of features to push a midi system well beyond the ordinary: multiple-sustain controls, mouse-controlled pitch bend, key-modulation, and more. I guessed that with a little bit of extra work I could create a system useful to many, and so I put sustained effort into creating a package that could be easily customized according to your needs. I also created a variety of annotated configuration tables to help get started.

Well, the "little bit of work" turned out to be a "fair bit of work", so I hope many musicians and developers find my system useful. If you think Midi Integrator has merit, please post about it!

That looks very interesting, I will have a look at it over the weekend.

Cool!

I have experimented a bit with HIDs in ChucK (mainly multiple mice), and a critical stumbling block for me was that i couldn't block the HIDs from interacting with the computer besides controlling e.g. a synth. So if I moved a mouse to change a parameter, it also moved the mouse pointer on the screen on my Mac. If I pressed a key on a keyboard, it typed something on the computer.

Is this something that your software can solve?

I've partly addressed this - for security reasons windows won't allow the mouse or the keyboard to be completely intercepted.
What I do is full-screen the program and run it stand-alone on a netbook that has been customized to run music - it won't go to sleep, anything that causes interrupts has been removed. I usually start it up, and close the lid.
I've also seen hints that on Macs that a second pointing device, a touchpad, can be assigned to be a HID, and hence feed midi modulation alone. Others will have to test this.
I've documented what internal routines in windows to turn off to turn off - I find that HP netbooks work well with ASIO drivers.
Does this answer your question?
