[Stk] Problems with sample rates

[SHARM info]

Hello,

I'm using several instruments (ModalBar, for instance) and I have a problem
with using different sample rates.

Everything works perfectly with 11025Hz.

Using 44100Hz is problematic. The amplitude is very low and it sounds
strange, like low quality bells with smearing sounds (hard to describe).

I set the sample rate before the creation of the instruments
(setSampleRate() before the new operator).

Any idea?
