Device U1 music of plants. How to get the right MIDI notes?

Laurent Pigeolet's icon

Hello,

I recently bought the U1 device which transforms the electrical signal injected into a plant to transform it into MIDI signals: https://www.musiquedesplantes.fr/product-page/boitier-device. It's pretty rudimentary: it just generates regular note sequences with note pitches depending on the diatonic or chromatic scale that we choose on the device.
When I connect it with a MIDI cable to Sibelius software, the notes that fall within the staff are identical to the notes produced by the device. Good. But when I connect it to Max/msp with the "notein" object to begin to develop a patch with that, the notes that appear are completely random, they never correspond to what I hear. I use the scarlett4 interface or the simple Romi / o: same results with both. What can I do in Max to get the notes right? Thank you very much, Laurent.

Strange!
Did you check in Max' MIDITester what kind of informations you receive from your device? Maybe there are 2 different MIDI streams, you should print the notein values to the Max console to check what comes in.

Of course, yes! Why didn't I think about that earlier? There are 2 streams indeed. Thanks a lot! Laurent.

Max Patch
Copy patch and select New From Clipboard in Max.

Parfait.
Au fait, there is a polyphonic mode for the nslider object.
Are both streams on different MIDI channels?

BTW, how does this device sound?
