Thread: Teensy 3.1 USB Midi - cannot connect to USB Midi Keyboard controller (iPad works ok)

    Teensy 3.1 USB Midi - cannot connect to USB Midi Keyboard controller (iPad works ok)

    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 ?

    That cannot work for the moment as the Teensy doesn't support USB host mode.

    Merci beaucoup, so I don't need to invest more time researching. A+

    If you have a standard MIDI din output you could connect it to the teensy vis a standard midi plug. The iconnect midi products can also act as a bridge between both devices.

    Thank you for your kind words !
    I designed it to midi-fy my Monotron Duo. It hosts a dual DAC and a dual digital potentiometer. With the Teensy 3.1 I have 3 DAC outputs in total.
    Here is a demo:

    The board is fitted with another I/O pad from the teensy, I thought that I would need it to generate the gate signal for the monotron duo - but it's no longer needed (unlike the monotron, the Duo generates its own gate signal).
    So now I will use that I/O as a Midi input.
    I made 5 of these boards, I still have 4 and just put one on eBay for sale.
