I bought a devterm without any idea what I was going to use it for, and now I think I know. I want to make a digital instrument using [Pure Data](https://puredata.info/). Looking into some of the things people have made to use Pd, I came across some videos of a rasPi with a soundcard hat. Is there any interest in a soundcard for the Devterm? ---

I’d love to be able to use mine as a synth, I’d thought about trying to install a few for fun ---

A tiny synth expansion that would generate the audio sounds real fun! I’m immediately reminded of [M8 Tracker](https://dirtywave.com/). That one’s actually powered by a [Teensy](https://www.pjrc.com/teensy/) microcontroller. ---

Quick plug to my thread about using the EXT for porting pi hats: [https://forum.clockworkpi.com/t/designing-a-ext-prototyping-breakout-with-raspberry-pi-hat-compatibility/](https://forum.clockworkpi.com/t/designing-a-ext-prototyping-breakout-with-raspberry-pi-hat-compatibility/) Here’s my hookup: ![IMG_20210701_145757](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/0/0652df5b4feb14c060904aceb0833cc22f090fe7.jpeg) Just waiting on my A04! But when it arrives I’ll be posting my progress on getting this soundcard to work. EDIT: Another pic. That PCB with the hat reduces to half-size. So those audio connectors will sit right inside the printer hatch. ![IMG_20210701_150813](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/6/611ff6528aed96d23123e96ec78df6f453cb0b20.jpeg) ---

[quote=“DustinWoods, post:4, topic:7181”] A04! But when it arrives I’ll be posting my progress on getting this soundcard to work. porting pi hats is an awesome idea! ---

I was looking at [Orca](https://100r.co/site/orca.html) as a sequencer and I don’t know exactly what for a synth. ---

I had the same idea myself! ---

Neat! Porting the hats over is a really good idea going forward. I did notice that they had the GPIO connector and thought that I should look into what is available. Just got my a06 and just starting to see what I can make it do. ---

Hal retweeted this: [https://twitter.com/patriciogv/status/1520857693484986371](https://twitter.com/patriciogv/status/1520857693484986371) I have also tried Orca+OPZ, works like a charm I was thinking “hmm why not use the 40pin fpc connector instead of a full ext. breakout board…” and I mapped it out: ![image](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/e/ef5823148ef4d2869c0e2768ddd9bf10f9cd1724.png) There’s no way this is going to be useful, and @DustinWoods 's way is the only right way. ---

right, so we only have a handful of GPIO available even if we took one of the FPC headers out on a ribbon… sad ☹ ---

Worry not: ![image](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/e/eb370799dc93c54ddd0c35ab8be41ccf401e2aa6.jpeg) Can also fit a Maya22 USB soundcard in there I believe. Did that once to my other cyberdeck/synth thing, when you remove the tall audio jack from the board the height should be acceptable.
