Hi all

I'm building a midi project that samples approx. 20 analogue signals and I need to do it as fast as possible. I'm wondering would it be faster to use 1 CD74HC4067 to multiplexer 10 channels to ADC0 and 1 CD74HC4067 to multiplexer 10 channels to ADC1 or, would it be faster to do away with the CD74HC4067 and utilize multiple channels on a teensy 3.5/3.6 and make use of the Teensy internal multiplexer?

any feedback would be much appreciated.

Ged.
