**Wave Morphing With Teensy 4.1 and Audio Adapter Shorts#**

A demonstration of using a Teensy 4.1 and an Audio Adapter Board to synthesise and morph waves types.

I have been having fun making sounds that can change. All these are done using the Teensy Audio System Design Tool, together with the WAVEFORM\_ARBITRARY type, which means I can literally design my own wave form on the fly and it is powerful enough to allow morphing between different wave shapes as seen here. Very cool!

This is awesome @John136772 ! I love your approach to DIY synth building.  
This can’t have been easy to create - Mad cred for the retro buttons, and split display too 😃

Thanks Michael, the whole project started because of the PB86 click buttons and also that Core stocked the PCB converter things and multiplexers. I used the Core Pico Devs OLEDs too as they were easy to use together.  
Not sure where I’m going with this next…
