My synthesizer (Yamaha mx88) is plugged into the back (which has no gain controls) of my audio interface (Focusrite Scarlett 4i4) and that is plugged into my laptop (MacBook pro) running Focusrite control and Ableton live. The signal reads around -36db. Is this normal? Why is the signal so low?

Sounds like your signal is too low.

This can come, e.g. from impedance mismatch (i.e. output and input aer a bad couple).

Sometimes using the headphone output helps.

A preamp inserted might help. However, e.g. with impedance mismatch, you may experience more noise.
