LED behaviour on M:S

Elektron Gear Model:Samples
#1

Hi All,

I recently bought a M:S and I realise the sample button LED doesn’t light up, nor does the wrench/config button or LFO button - is this normal?

I’m fairly sure that ‘sample’ and ‘LFO’ only light up when locking that parameter.

I can’t remember what causes the ‘wrench’/settings button to light up.
