TX-6 and send/return to external effects pedal

I’m wondering. Can you send and return from the TX-6 to external pedals? Or maybe even to iPad effect plugins? I’m just curious since I’d really want to expand on the built in effects of the TX-6.

I think they mention using the aux output for this in the user guide TX–6 guide

Yess, this is the intended use of the AUX output. I have used it successfully with a couple of UAD Pedals which are stereo. This video is using a pedal on AUX. https://youtu.be/wp3_J4cjjBs and here’s one using an iphone Using the iPhone as a send effect on teenage engineering TX-6 - YouTube

Yes. I do it all the time with my Chase Bliss gear.
