Hello all, I'm posting this after hours of trying various things that don't quite work, I'm sure the answer is staring me in the face but so far not revealing itself. Here's what I have: a linear actuator (car door motor) connected to a drum stick that creates a powerful mechanical drum...

Hi, I'm making a musical instrument which contains four Teensy 3.2s: one which is connected to the computer via USB, and acts as a master MIDI device, relaying messages out from the 3x serial ports. I'm using quad audio boards for multiple audio inputs hence the multiple teensys. My question...

Hi moo, a quick question to see if this is what I'm looking for. I want to make a sampler that does this: a live input can be sampled for as long as a button is pressed. A pot can then change the playback speed of the sample, so that for example the sample can be downtuned and played back very...

just want to say I'm really impressed by the build quality of this. Well conceived and executed, congratulations!

right so I did what others have suggested in previous posts as an intermediate work around: set up 3 different controllers one as MIDI, one as Serial + MIDI, and the other as Serial+MIDI+Audio. Each come up with their unique names which solves my problem, for now, unless I decide to add another...

hi, I've tried the suggestions listed in the documentation and the product ID definition, tried deleting devices in Windows Device Manager (Win 10) but the two devices I have keep being renamed in Ableton Live to whichever one was last plugged in. I have one called "footswitch" and one called...

I figured it out. As usual, writing down the problem in a logical manner both here and subsequently in code helped me figure it out. I replace the playFile function with this: void playFile(int out, const char* filename ) { unsigned long currentMillis = millis(); Serial.print( "Playing...

Hello, I've built a custom PCB around the Cirrus Logic CS42448 TDM chip, and have 8 mono outputs through which I want to play audio samples from a Windbond W25Q128JVSIQ flash. I can get samples playing no problem after a few days of figuring out how to get to that point, but now I'm...

nice one, I'll try that. Thanks for the suggestion, will let you know how I get on!

Hi, I'm trying to use a keypad library with teesny 3.2. When I compile the example I get a bunch of errors that look to be related to the wire.h library. It compilles fine for Arduino Uno. The library in question is written for use with the MCP23017 port expander, and is called Keypad_MC17...

Ok so I hacked together code from the examples (Record and sdToFlash) in order to record incoming audio from the line in of the audio board to SD, then immediately copy that to the flash chip. It then plays back from flash. However now that I'm attempting to make this work with four parts...

Hi, I couldn't find an answer to this in the forum but I'm wondering if it's possible to save audio data from the line input directly to a flash chip (I have a W25Q128FV soldered to the Audio Board using Teensy 3.2), or if it first needs to be saved to SD and then transferred into flash memory...

in terms of a nice easy to follow tutorial, this guy did a nice video series that helped me a lot when I first got started with the audio library: http://www.notesandvolts.com/2018/05/teensy-synth-part-1.html

+1 with the exact same sort of set up and notes cancelling...any advice appreciated. Did you figure out a solution to this Joyfultalk?

Hi, I'm having a problem with the example code SamplePlayer from the audio library. Its plays back the samples on button presses as expected when the teensy is powered by USB / connected to the computer, but when I power the unit with a USB cable connected to a regulated 5V from an LM7805, the...
