Got some questions a the end, concept and design first. Welcome any feedback. Concept Concept isn't anything particularly unique. There are several things out there in synth land that do similar, my concept just does a few things in a way I would like more. A lot of granular samplers us the Pi...

Might I suggest what you are looking for is called a "fully differential amplifier". Here is a good article on the subject https://sound-au.com/articles/balanced-io.htm. Your old pro audio gear used to be entirely fully differential, but as you can see you have to double your part count...

Back in 2016 I had made a thread https://forum.pjrc.com/threads/40982-3-6-as-a-Modular-Synthesizer-DSP and ended up doing some analog projects instead. Decided to give digital another go and saw the 4.0 was coming so cooked up a new design. You can see my design here...

I would suggest starting with a stereo effects processor and an analog mixer with effects inserts as separate projects. Looking at how to scale your inputs and outputs is important. You will want to protect your teensy/codec/ADC/DAC with buffer op amps and current limiting. Buffer op amps...

I posted in these forums a while ago about doing something with TDM that may have spurred Paul to make his test boards (a lot of I/O in eurorack). Since my idea of what to do has changed a bit and I am only looking to do 4 in 4 out. I was wondering if there is any roadblock to using a WM8731...

Yeah, I am now diving into the codec datasheets. Need to do more research so I can ask the right questions. I am eyeing the TI PCM3168A right now with its 6ADC/8DAC, no switching. http://www.ti.com/product/PCM3168A/description There is a nice write up on an application here as well...

Thank you all for the great replies. Looks like I have a lot more research to do into TDM and such, thanks for putting me on the right path to more understanding here. The TDM is all new information to me, but it looks like a good fit to my application. If the DRAM is good enough for the DLD it...

I already know something like this is possible and will be basing my path forward on successful projects like Ornament and Crime https://github.com/mxmxmx/O_C My own experience with microcontrollers is a graduate level mechatronics course that mainly focused on motor controllers and the like as...
