When the instrument has enabled filter envelope and lowpass filter is selected, Xnn (panning) has no effect - the sample is always played in the center.
Moreover, there are some issues with other filters:
- Bandpass seems to have no influence on sound (or I have hearing problems)
- Highpass, Lowpass2 and Notch do not produce any sound when enabled.
