Thank you. It worked.

I'm trying to read a simple signal from an encoder. I've been having terrible luck, and I just want to make sure I'm using a proper circuit. I'm using this encoder http://www.alps.com/products/WebObjects/catalog.woa/E/HTML/Encoder/Incremental/EC10E/EC10E1220501.html (which I'm interpreting as...

I've been trying to read changes from a simple rotary encoder. I've connected the encoder's two pins to pins 14 and 16 on the Teensy 3. There is also a third pin on the encoder. I am under the impression that the first two pins handle the encoder portion while the third pin handles the button...

I have been getting very inconsistent, glitchy output from my teensy and breadboard setup. My intention was that a button/combination of buttons would result in a certain message to the console. However, the message would chatter unpredictably. For the longest time I thought there was a...

Issue is solved. Apparently the Android Grand Piano app has a default setting of "Output to Midi/USB". Once I deselected this, the notes continued to play. Still, I'd like to know why changing this setting fixed the problem. If the problem was simply message transfer back to the Teensy...

As an addendum to the above info: When I connect the same code to Midi-Ox (and my PC's default Midi Synth), I also only hear a couple of notes played before it stops. On Midi-Ox, I hear no new notes playing AND I see no new messages appearing. In other words, the problem seems to be on the...

I installed Midi-Ox and verified that the Teensy was in fact transmitting. I then added a large delay in the setup() function. Android's Grand Piano Pro was finally able to play sounds from the Teensy. However, the app plays the note only four times and then stops. I figure there must be...

I apologize for the repetition. I was trying to generalize the question more. I will try Midi-Ox later in the day. I tried setting up Midi-Ox on a different PC before with limited success, but at the time I was having problems with Arduino (hence trying Teensy now).

The Teensy supposedly emulates a Midi USB device, but I have not been able to get it to play any notes on an Android keyboard app. The Android keyboard app supports Midi USB, and it play notes when connected to other USB Midi controllers. My Android device will recognize a Midi USB device, but...

I have no way of testing it with a Mac or PC. I have no Mac, and my PC does not have any sort of DAW or MIDI keyboard.

No, that didn't do it. I'm not sure what other information there is to give.

I am trying to make my Teensy 3.0 play notes on my Nexus 7. The two devices are connected via a regular USB and an On-the-Go adapter cable (I've see these two cables work fine with an ordinary Midi controller). I also selected "Midi" under board type. After I plug the Teensy into my Nexus 7...
