pretty cool delay sound! sounds warm and analog,
although digital! and looks pretty cool, too!

Sounds amazing. did you use only the teensy memory or some expansion chips?

Nice!  I'm not sure how you built it, but it's totally neat.

Hi, great project! I'm doing something similar using a Teensy 3.1, the Audio Adaptor board and an Oled 0.96" display, just like you did. The thing is both the Audio adaptor and the OLed disp use SDA SCL signals of the Teensy board. How can you possibly handle the same signals for different purposes? I took a look to your blog and I couldn't find an answer to my problem. Thanks! Cheers, A.

Love this project, I've been trying to do pretty much the same thing, in an attempt to make a delay unit for an active speaker (delay tower). But I experienced a lot of noise-problems, possibly related to impedance or perhaps because I need to disable some auto-volume or set line-in-level and line-out-level for the chip differently. I use the line-in and line-out terminals on the audio board. Did you experience anything similar to this, and how did you fix it? Is there any chance, you can publish some of the source-code? (primarily for setting up the audio-part). I would be very grateful for any details, you can provide :-)

Do you think a Raspberry Pi Zero W would be a suitable alternative to use for this project or does it not have as much processing power/ real-time capability as a microcontroller like the Teensy?

how complicated is it to give audio i/o to a Teensy for a hi-z instrument like a guitar? i guess there needs to be an opamp on the input side, some kind of voltage regulator to protect the teensy on both input and output, anything else? Is there a thread at PJRC you'd recommend by chance?
