When more connections are established, the library pauses every now and then.
This stops the whole program for a few seconds.
How can I fix that.
I am using version 1.0.5
Thanks in advance.

@hupool - Something to keep in mind is a lot of thumb drives have small write buffers. I have a 16G Kingston DataTraveler 3.0 that can only do 1.5- 1.6 MB/s. This a fairly old thumb drive. A newer 128G Kingston drive...

Hi,
for a sketch with Teensy 3.5, developped on Arduino IDE/Teensyduino, I want to use data types uint8_t and uint16_t.
What header file has to be included to know these data types?

As noted in #2 above that's exactly the problem - AudioEffectEnvelope (and pretty much all audio library classes) inherits from AudioStream.

@lokki - would be interesting to see the startup of the sketch. For example with my Bamboo one it starts with:

Yup ... change your calls to AudioEffectEnvelope functions to use float values for the parameters, so for example env2.release(0.0f).
You've passed an integer to the function, and as the error messages are saying,...

Thank you. I should have known it was the serial buffer. I have to figure out how big the block actually is and how to get it through with the code. I appreciate the information.

I think that's correct. It's not just TeensyThreads, but rather any RTOS with a stack per task. And T4.x is okay because it uses smalloc() rather than malloc?
