I've Run Out of Memory - Static Machines Time?

Morning all . . .
I’ve had a quick experiment with the static chain from card thing . . .
I checked that other chains read from the card okay. I’ve got some percussion chains and they work fine from static. Looking at the electric piano chords though, they show ERR even in the browser!
I’ve noticed also that the details at the bottom of the screen differ for the percussion and piano chains.

Percussion 44.1 24b 2 Ch with a smiley face
Piano 30.4k 32b 2 Ch unhappy face.

Both work in flex. Only percussion in static.
