Summary0000008: OpenMPT needs a filter mode that is compatible with Impulse Tracker
Description

Currently, OpenMPT's lowpass filter doesn't sound anything like IT's own filter. Thus, OpenMPT needs a filter mode that sound more like Impulse Tracker.

Additional Information

I've adapted IT's filter formulas and tables in Revision 1075. The filter pretty much sounds like XMPlay now.
