... I really like your idea, sounds interesting. A few years ago I used one of these "hire a developer" platforms to start a project for something similar. I am probably one of the longest time user of MIDITEMP MIDI matrix systems. Bought my fist one in my hometown where they started after leaving the university.

On what platform are you working? What hardware will you support?

Don't know if it is possible to writ a PN on this board, would like to hear from you ...

Bests,

The product is already released, so you can get your own free 30-day trial copy that is fully functional and try it out. Just go to muckuper.com, register and download it.

It currently runs on any PC with Windows 7 and above. I even tried it on an inexpensive (<$180) Windows 10 tablet and it ran great. Working on a Mac version next. It comes with a file to integrate with SONAR, instructions on how to integrate with Ableton Live, and a Lemur template to remote control your performance from your iPhone or iPad. If you have a touch-screen PC or tablet then you probably will not need the iPhone control because the performance mode buttons were designed for a touch screen.

You can use any MIDI hardware, MIDI bridge like LoobBe30, and connect to anything that can send or receive MIDI. You can use it with as many physical synths and virtual synths as you want, (in case of virtuals, as many as your computer will handle), And you can layer and split any of those synths onto the same keyboards or pads, make chords out of notes, make intervals, transpose, convert control messages, and lots of such goodies. You can even merge MIDI from different sources to the same device (for example a separate pad controller and keyboard). In the end, it lets you organize all these layers, splits, etc.as scenes that you assign to songs. You then assign songs to a setlist, launch performance mode, and the program will step you through each scene like you have a new gear setup for every song. And it does it smoothly with no glitches, so long as you are mindful of the limitations of the synths you are using.

If you follow the YouTube link on the site you can view demo videos. My playing is mediocre, but you will get the idea of what can be done. Let me know what you think!

Hi. You can also check this site https://github.com/TheKikGen/USBMidiKliK4x4 https://github.com/TheKikGen/USBMidiKliK4x4. It is a hack based on the Midiplus / Miditech 4x4 midi interface. That firmware solves the "Same productid/vendor id" issue, and add multi-routing features. More, you can rename the USB device with SYSEX...

the theoretical limit of the operating system and DAW or editor software will in all case be futile, because the bottleneck is usually the number of clients supported by the USB driver.

some interfaces like the ones from opcode support at least 8 devices (for both serial and USB), others only support 4 or even only 2 (steinberg midex-8 USB under OSX PPC)

in other words: for 40 devices it can easily be realized by simply using midi interfaces which allow 4x 15-port or 8x 8-port clients per 1 host computer - or mixing different brands of interfaces.

for extreme uses of midi under USB 1 one should be aware about the bandwidth (31.3kbit/s per midi port vs 12,000 per USB 1.1 port suggest a limit of ~500 midi ports) but i am probably the last person who uses USB 1 equipped host computers anyway.
