>2 Channel audio using MQS (Teensy 4.1). Is it possible?


New member
Hi There!

I'm completely new to the Teensy platform, I've chosen a T4.1 for a simple drum machine project using the Teensy Audio Library. I've messed around a little with the single-pin PWM and MQS schemes for audio output, and was satisfied with the quality of MQS, however I noticed documentation from PJRC only mentions 2 channel output. I'd like 4+ channels if possible.

The datasheet for the MCU (iMXRT1062) is vague on whether it supports more than 2 channels, It just says that MQS can be used for 2 channel audio from 2 "standard digital GPIO pins", of which T4.1 has many.

Can anyone advise me on this?
