Hopefully I am wrong, please someone say so...
I did find a lot of examples showing how to use the teensy as a MIDI controller. But I want to use Teensy as a sound generator, and I want to connect a keyboard controller to it.
This is very easy to do with an iPad for instance and I have done that.
However, it appears that it does not work in general with a USB Midi keyboard controller, and I can't find instructions to make this work.
Can anybody help please ?
