@InvalidSyntax(2):
In my project, I was using the Audio Adapter, which has the headphone jack right on the board. Sorry, I don't have any experience with making use of signals directly from DACs.

Sorry, I overlooked the fact that you are using the Teensy LC, which, as Paul pointed out, does not have the required USBhost port. Sorry that I did not really answer your question completely and/or correctly. ...
@syusaku sano:
Using my best guess from your pictures and your description, I am guessing that the connection between the PC and the Line6 pocketPOD is via USB. If that is the case, you will need to connect a USB...
@InvalidSyntax:
I can't speak specifically to mixing USB audio with waveforms, but I can tell you that in my TeensyMIDIPolySynth project (which used physical pots read thru analog pin inputs to adjust many different...
@luni:
Nice !!
Would it be better to move the calling of "Serial.println("triggered <--------------");" down into loop(), where the "start" condition is detected, rather than having it called in the onTimer()...
Not 100% sure, but I'd bet that tutorial is for the older AVR-based Teensies & isn't appropriate for the Teensy 4.0. Take a look at <this> thread & see if it will get you where you're wanting to go . . .

Being in the US, not sure if either Adafruit or SparkFun are available for you in the UK. If the 74HC595 will work for your application, Adafruit sells the individual ICs (3-pack) & SparkFun sells a convenient breakout...
Q1 (with Q2): with two channels, each with gain set to 1, the output audio will be a combo of the two inputs without any attenuation or amplification?
A1 (with A2): Yes. Note that, if the two inputs are both full-size...
You beat me to the punch . . . sorry to come late to the party, but happy that I'm at least walking a similar path !!
So, how about if, in addition to the interrupt at zero crossing which manages turn-on, you run a...
@SoulReaver:
Whoops, I should have paid more attention to the fact that you are using a T3.2 . . . you are entirely correct that it has 5V-tolerant pins. Mea Culpa !! (I'd use the excuse that I play strictly with...
I have not messed with either a zero-crossing circuit or with dimmers (since the long-ago TRIAC choppers . . . I'm showing my age !!), but could you use the following:
- globally define & initialize (each to full on)...
@SoulReaver: Looking at the wiring setup image from your OP, I would check the output signal level from the IR receiver (using an o-scope, not a meter...your meter will not give you the peak value, which is what you...
Stick with it, you're very, very close to accomplishing your intent !! My compliments on your work & your persistence !!
Try making the simple changes flagged below in RED & see if that makes a positive change to...
@NotSo:
Let's see if I understand your intent correctly:
I) detect a sound & determine its frequency
II) send a MIDI NoteOn for the note/frequency detected
III) if/when the sound goes away, send a NoteOff for...
Maybe you just made a simple typo, but I would not expect any well-designed device that is intended to provide USB power to be putting out anywhere near 6VDC. Prior to USB 2.0, the USB spec defined 5.25VDC as the...
@ralphhipps: For clarity, the "# key" that BriComp refers to is the "#" button located above the editor area (not the "#" key on the keyboard). You can use one of the following ways to make use of this button, which...
