Is there an easy way to call SDbegin() for ONE music maker from TWO different 3.2 processors using SPI?

Basically a way to call playTrack() from both processors without SPI conflict?

.. just playing SD sound .wavs... not saving data to SD

disable one teensy SPI while enabling the other? impedance settings for SPI? two masters, one slave?

Anyone do this?

I did read that SDFat has this capability, but still wondering if someone has a code /hardware setup example....

THANK YOU for any pointers or links!
