What I generally prefer is to use stacking headers. Adafruit sells 2 14-position stacking header + 1 5-position stacking header that is just right for the Teensy (or the Adafruit Itsy-Bitsy which uses the same 14-pin side pins + 5-pin rear...

Physical space is not an issue and I don't plan to use the sd card on the audio shield, so I figured it would be most convenient to have access to the button on top. Does that restrict me in what pins I have access to on the board in any way?

That's what I have (pictured above). I think I just need to get longer female sockets to get it to work with the breadboard.

Thanks! I couldnt find 14-pins that were in stock except on Amazon

Long headers Something like this will do the job.

OK, what is the best way to stack these if we want to use a breadboard? I have found some longer female stacking pins on amazon, that I could use like this, (but with longer pins on the bottom of the stack).

Hello, I bought the recent sale package with a 4.0, pins, and audio shield. I want to be able to use them with a breadboard while I develop my project, but I am unsure about the correct way to stack them together before soldering. The pics show...

And it is faster if not bigger on the inside too. Congrats.

Just received my Teensy today... it's smaller than I imagined. I'm excited to get started soon!

I'm looking at this display, it appears to be approx 3" wide viewing area with 20x4 character space, https://www.amazon.com/dp/B0D2L9VGQ9/ Only 4 wires to connect. Any ideas if there would be any electrical or code problems with using this LCD...

Take a look <here> for the recommended MIDI circuitry. MIDI on the Teensy is very easy, and the audio library capabilities are fantastic !! Mark J Culross KD5RXT

I just ordered a 4.0 + Shield & pins on the black friday sale. I already have a box of potentiometers and several sets of resisters/caps and a breadboard. I have 5 KY-040 encoders in my amazon cart, but I'm wondering what exactly will I need to...

Thanks Mark!

Hiya, that looks perfectly achievable with a teensy. Couple of things you asked about, that I thought I'd address, regarding the encoders and presets. If you look at the "KY40" type encoders, they're a mechanical encoder, with a push button...

The PJRC Audio Adapter Rev D stacks perfectly on top of either the T4.0 or the T4.1 (the pinout of the Audio Adapter matches 1-for-1 with the Teensy). It is not recommended to hard solder them together, but rather to use stacking header pins &...

@Paul Hesketh Thanks so much for the answers. This is enough to get me going in the right direction! One more question, is it logical to start building with the bare audio then upgrade and update the project to audioshield later? Money is not an...

@kd5rxt-mark Thanks for the reply! I have used an iPad with Audiokit Synth One and while I like the sound, I am not thrilled with the touchscreen experience. that's why I'm wanting to build something with physical knobs. But who knows, maybe I...

I've been noodling on this synth idea for a long time, and it looks like a Teensy can do what I want to do: An 8 voice polyphonic, 2-osc subtractive synth. Amp and Filter envelopes, 2 LFOs per voice, and one or two global LFOs. The first row of...

Hi! I made another Teensy-based polysynth using parts from other discarded projects. It is the usual subtractive setup but I am trying to make it more flexible in terms of modulation to create more variety than my previous attempts. I would like...
