Porting Audio Library to Debian/Raspbian

Hi guys,
I've recently been working on my polyphonic synthesizer on PlatformIO with cpp.

I've been looking to add more features i.e. 4 track mixer, AI stem splitter, etc. but ran into some memory limitations.
I decided to look into the Raspberry pi CM4, because it has way more memory, and I'd also like to try HDMI graphics and the built-in wireless.

I really like the Teensy audio library, and would like to keep using it.
Could someone help me with porting to debian/raspbian? I'm definitely a beginner to linux/compiling, but very eager to learn.
I have a Pi 400 right now for testing and am looking to buy a CM4 soon (when I can find stock)

Lastly, would I need a Teensy compatible DAC? I've seen other people use the audio shield with Pi https://forums.raspberrypi.com/viewtopic.php?p=1906303&hilit=teensy+audio#p1906303
 
Probably much easily to stay with Teensy running the audio library and add a Pi just for user interface. Probably best to connect then with serial.
 
You could also connect the Pi to the teensy using the i2s interfaces or using the USB audio interfaces
and thus having some memory/cpu intensive processing taken care of by the pi, but still use the teensy for the other fun stuff

I have also been thinking porting the lib.
That was mostly because I wanted to simulate the sounds before putting them into the teensy,
but that would soon be doable with the OSC implementation + live edit.

Also porting the lib would not be fair to PJRC

4 track mixer, what do you mean?

Do you know that you can add total 16Mbyte of external PSRAM?
