thanks Robert and Giulio. I have fixed the issue, which was very simply that I had the power hooked up wrongly. I think what threw me off was that there is still audio output even though the op amp was not powered. The module is soooo much more useful to me now the audio output is at a level of other eurorack modules. And still the debugging/learning experience was useful also. I think perhaps a note on the testing page that audio may still output even if the amp is not working maybe be helpful to others, also to double check the power

yeah i've tested it again, and that is what happens. perhaps i am testing wrongly. i am using a multimeter in DC volt mode to test against the other end of a eurorack jack that is in the audio out of the pepper, black lead on the long part of the jack and red lead on the tip of the jack. also when i remove the power from the amplifier board i get the same results (i am unsure why i get audio output). i will double check the components and see if I can unsolder and reflow the joints tomorrow. (a bit difficult with the way the board is attached).

On this page https://github.com/BelaPlatform/bela-pepper/wiki/Building-the-Module it says that the "The text of the regulator should face towards the bottom of the PCB." I'm not sure what this means? Is the bottom the other side of the board or the bottom where the buttons are? I'm assuming the buttons as the square (12v) pad should be the input to the regulator according to the datasheet https://recom-power.com/pdf/Innoline/R-78-0.5.pdf.

Were you running Orac before you updated the software? are you sure its deteriorated?

No I am a complete newbie, just trying things out before getting into the weeds. I am not sure how well the previous version performed. I might do some more testing and get back to you.

Beaglebone AI

Hmm, I don't know much about this, would it be a drop in replacement for the beaglebone black? I guess that would make it a neat upgrade for my pepper once it's built then!
