Yeah for sure! what you have made has so much potential : ) I will keep an eye on the forums for progress on the multi in via USB. keep up the great work!
A

such great work! have you been able to get more than 2 channels of audio into the Teensy via the usb? A

great work! keep us updated : ) I am really keen to be able to run more than stereo audio track into a Teensy via the usb.
A.

The original poster has gone quiet I think but if you are able to take this on that would be amazing! Would be handy for many people on here

Ta recursinging!

4 of the Teenys have loops loaded into them which can be triggered together using the buttons which are conneted via the keypad library. I have stereo outputs for Drums, Risers,...

Few pics from the build!

Its back up! here you are : )

there is actually an issue with the video! the host is taking it down and it will be going back online tomorrow! : o

Hey all!

Here is a live video I put together using my Teensy setup:

And here are some pics of the build:...

Thought you guys might be interested in this post.... https://github.com/greiman/SdFat-beta/issues/51#issuecomment-646184476

It seems Bill doesn't have any interest in developing SDfat further...

Thanks KurtE, sound advice. Looks like its just the examples that have been updated as you say.

Hello, what are the minor updates to SD and Wire examples? will the SD changes help with playing audio from an SD?

Ta Dionysus, unfortunately they are only 8 megabytes and I need several gb minimum!

Ta for the input both : ) The code in my original post actually didn't work in the end so I would avoid that. I have spent today setting up a Teensy to work with the Tsunami and provide a legato...

Ta for the replies gents. Cool looking kit boxxofrobots. If possible it would be good to keep this thread on topic. I really have no interest in running linux, and the SD issue with the T4 seems...

Ta for the message, I can't code in python and really don't want an os running so pi is out of the running.

The SD issues are present even if you only have two wav players so I am sure it will get...

Thanks for the reply Newton!

I since abandoned trying to get 8 working at the same time, I have 4x Teensy 4.0 networked using serial and they trigger 2 tracks each. I have put well over 2 weeks...

Here is a link to a quick how to I did for getting 2x PCM5102A in quad working on T4..

https://forum.pjrc.com/threads/60988-Teensy-4-0-Quad-I2s-with-2x-PCM5102a-Working

I have asked the in the SDfat SDIO T4 thread if there is a solution to the hangs caused when playing multiple wavs and provided example code...
...

Hello all! I am trying to rid my system of clicks and pops when loading multiple WAVs, several people have mentioned the issues with SD.h so I am trying sdfat on T4. SdFormatter, SdInfo and...

this is great, good shout changing the colour of the slaves, that makes life a lot easier.

For what its worth I like having access to all the inputs, outputs etc in a large list rather than menu...

That is great info thank you. I have been working through this with a friend who is a much better programmer than me and he said a similar thing about having a multi-threaded runtime. I wouldn't be...

This demonstrates the issue even more clearly. 4 WAVs launched at the same time creates the drop out i am talking about if you trigger it a couple of times..


#include <Audio.h>

No issues with SD read speed...


SD Card Test
------------
SD card is connected :-)
Card type is SDHC
File system space is 63848.94 Mbytes.
SD library is able to access the filesystem...

I think I just need a way to buffer the audio but as wavs only play at realtime I am not sure how to go about it. I was hoping to increase AUDIO_BLOCK_SAMPLES to make the lib more robust to clicks as...

So this code shows part of the problem. triggering the sample that is already playing should result in a click but there is a bit of distortion in there as well that you can "tune" by adjusting the...

it makes more memory available but doesn't fill it with buffer which is what i would like to do : )

awesome stuff! I will keep an eye on progress and most likely get a couple once they are available : ) i only need 4 outs per teensy but keen for high quality.

I would really love to be able to add some buffer in the audio library to prevent pops and clicks. if i have a couple of wavs playing then i get pops and clicks when i open envelopes. its fine with...

That is awesome! Nice work, how many can you daisy chain at the moment and do you have to SMD solder to get them up and running or do they come populated from the fabricator? hype!

Thanks for the reply! That makes a lot of sense. A friend of mine pointed out that I can probably solve this problem by using AudioRecordQueue and AudioPlayQueue to create a buffer! Looking forward...

since writing the above post I have noticed some files load better than others, even if they are the same length file name and same size file :/ I managed to get the Sdfat.h beta to compile with the...

After 3 or 4 brutal days of trying, failing and trying some more I started back again at the WavFilePlayer example and built it up into a test sketch to try and work out why I was getting clicks and...

Someone else feel free to correct me on this if I am wrong but I am pretty sure each I2S connection needs constant data or it wont work, it doesn't work like SPI.

I have just spent a lot of time...

Hello!

I am struggling to stop and play multiple WAVs from a fast SD card on T4 without glitches
In the audio sys design tool uncommenting #define USE_TEENSY3_OPTIMIZED_CODE in SD_t3.h is...

Thanks Michael, after lots of tinkering I have realised I don't need 2 way communication, so I have the master with TX connected to the RX of a slave, next I was thinking of just adding another wire...

I managed to get my code to compile using the Adafruit TFT lib but whenever I called playwav it would hang unless I commented out wire begin so I have admitted defeat and I will use UART. Thanks for...

The Audio Boards would need a redesign to be able to use SPI for control I am pretty sure. only the control data is sent via I2C. audio is sent via I2S which is a common protocol for sending audio.
...

Okay So! I have audio working via updating the control elements : ) thank you for your explanation.

I have now added "#include <ILI9341_t3.h>" for the screen I am using. Here is the code and the...

Thanks for the reply. I am pretty familiar with the Arduino i2c library but I have never used an arduino/teensy as a slave before. I just want to send trigger messages of a few bytes from one to...

Thanks I will look into rs485, I want to send a signal from the master to several slaves all at the same time, as well as communicate with each individually. Maybe my time is better spent looking...

Thanks vjmuzik, I wasn't aware you could easily talk to multiple devices using uart, I will have more of a look into that. Is there a suitable library known working for T4?

edit: it doesn't seem...

If I do this in WireIMXRT.cpp which is where the error is caused when I add Audio.h


//#include "Wire.h"
#include <i2c_driver.h>

I get a whole heap of...

Thanks I have realised that is what I need to do but searching Audio.h for wire provided no results.

edit: i see it shows where the issue is in the readout.

Also if I go down this route is...

As per the topic. I need to get a few of these talking to each other! There is no slave options in any of the libs it seems...

I have tried RichardG's valiant effort at adding I2C slave to the...

Hello! All was looking good until I tried to include the audio lib or the lcd lib, it then throws lots of error on compile. here is the code... T4 on 1.52. What can I do? It compiles fine if I remove...

I found the info in various places on the forum but not all in one place so I thought someone might find it useful like this...

Thanks to chipaudette who provided the test code...

Looks like its just in in the new version! Did you get one of your boards made JayShoe, is it up and running?

It really sounds like #define USE_TEENSY3_OPTIMIZED_CODE would fix my issue but even just on the wavplayer example on T4 it wont compile...
