The attached pic was this:
In these day I went on with my tests... and this assembly showed some limit: with intense use of the chip some errors appares. I guess if a small PCB with its groun plane could help data...
Hi Michael,
I had not notice that!
So.. thank you for your detailed analysis: at the moment I would remain on Teensy 3.6, or maybe switch to T4.0 in a next release; and for all the topics you point out I have no...
But... I found this post:

It says that for polyphonic application (mine uses 8 voices at least) it's raccomanded flash chip, not SD...
Good suggestion! I had not considered this!
For my application, the midi expander:

100M for file system is more than enough!! :o
This is so important to me! I didn't know this fact of quad SPI... Maybe it means that reading data rate from micro SD card on Teensy is comparable/faster than from flash memory soldered on Audio shield.. :rolleyes:...
Hi Michael, thank you for your answer; I didn't get if you are talking about W25Q256 32M 16-pin chip or about the W25Q128 16M 8-pin chip (which is not my case); I'm using SerialFlash in my code.
Maybe I'm too...
Hi all, I'm experimenting a W25Q256FV 16-pin SOIC 300-mil on Audio shield Rev B (on teensy 3.6, clock 240MHz), in order to store audio files to be played. Actually I have connected the flash chip with short wires:
