    Thank you Pete, that's great! This forum is brilliant :) Within a few hours of reporting my issue I had both a great temporary workaround and a long-term fix - incredible! :D
  2. No worries, thanks for having a look!

    An interesting development! I've just tried changing the code so that the connection is declared statically, and the behaviour is exactly the same. Here's the code I've just tried:


    #include...

    Yes, sadly I come from the world of Javascript, and haven't managed to rid myself of those tendencies! I was aware while writing the code for my synth that RAM usage might be an issue, but the Teensy...

    Thanks for the reply! Yes, that would solve the particular problem that I have shown in my example, but the problem is that I think I have to create new connections to do what I'm trying to do (which...
  6. Audio stops working when repeatedly creating/disconnecting AudioConnections

    Hi all, I've found some behaviour which is either a bug, something stupid I've done with pointers, or just me pushing the audio library past its limits!

    I've been designing a modular synth where...

    Looks like you're only reading the value from the 4051 once per loop. I think you need to do analogRead(19) (and the smoothing code) each time you change the channel of the 4051 (six times per loop...

    Oh cool! Thanks for featuring it :) Teensy is such a great platform, it's perfect for the sort of thing I like to do, making musical instruments that don't require a computer. Fun fact: last week, my...

    I've now finished the project, and I'm really pleased with how it turned out. Here are a couple of videos of the synth in action:

    Teensy-based modular synth system

    Hi all, thought some of you might be interested in a project I'm currently working on for the Hackaday musical instrument challenge. It's a Teensy-based modular synthesizer:...

    That sounds like a good idea, I'll see what I can do.

    Okay, looks like you were right! I declared the output object at the beginning of the sketch (since there'll only ever be one of them anyway) and it now works. Thank you!

    Thanks for taking a look. There is an I2S audio object but it's in the Output.h class. The code is a bit unusual in that I'm trying to make a modular synth, where you can add and remove various...
  15. Strange error when reconnecting Teensy (audio board not working on reboot)

    Hi all,

    I've got some odd behaviour in a sketch I've written. It's a fairly complicated synthesizer sketch but it works fine on my Teensy 3.2 with the audio board, until I unplug the Teensy and...

    Great, thanks Pete. New (final?) version live now, including u-law encoding by default. Think that means all the features of the original are now implemented (plus bonus MP3/FLAC/other format support...

    Cool, went back and rewrote the code that created the 32-bit words, and the unaligned.wav file now seems to work. There's still some extra padding that isn't created by the original wav2sketch...

    Thanks Pete, that's really useful - getting the same NaN result at my end with that file so will look into it. Just uploaded a new version with support for different sample rates. U-law compression...

    Brilliant, thanks Pete :)

    Ah, well spotted. I've now fixed the code so it doesn't produce a 9-digit entry - the problem was that I had only been testing with very short sounds.

    If I've understood the original wav2sketch...

    Thanks, Paul! I'm actually writing a tutorial for a magazine in the UK about creating a basic Teensy drum machine, will send you a link when it's published :) Is there a link anywhere on your website...
  23. Online version of wav2sketch utility - need testers please!

    Hi all,

    I've attempted to make an HTML/Javascript version of the wav2sketch utility that converts WAV files into Teensy-compatible code. Would anyone be willing to test it out for me? Have only...
