Hello to everyone, I start a project of synth with teensy 3.6 via its internal dac. I found a simply sketch to try the MIDI to synth connection.
I connect on USB Host port an ARTURIA MINI LAB MK2 MIDI CONTROLLER. The power supply is only from teensy USB via computer.
The system work well but I have a noise on DAC when any led on the ARTURIA goes ON. If any led don't blink the sound is good, but I have a 400 Hz noise perfectly synchronous with the blink led.
If I press one PAD with led the noise is continous.
If I use a phone charger for teensy, the noise is so low ( but present anyway)
I use this code:

thanks a lot
