Then click on options, then choose the "Audio/Image Sync" option. This option gives slightly more DSP resources to the .wav player and things are happy. I also play sound files off of the World Wide Web while connected via modem with no problems. note that although you *can* have 14.4 modem and .wav audio (i.e. digitized audio) at the same time, you *cannot* have MIDI sound as well without shutting down the modem. in order to have MIDI synthesis, you cannot be running either the modem or telephony stuff at the same time. since MIDI needs to be "by itself" anyway, it makes good sense to set all the MIDI stuff to the hightest quality sound (i.e. use up all the DSP). to do this (in windows at least) go to the mwave utils group and choose "select synthesizer" and choose "32 voice synthesizer". then go to the control panel, choose the MIDI mapper applet, and select setup "Mwave Ext. GM". doing this will result in noticiable better MIDI sound, especially on MIDI files with lots of instruments (quite decent actually, except maybe the drum patches are a somewhat lacking). considering most other "multimedia" notebooks only offer .wav sound to begin with (or pathetic FM synth MIDI which sounds like crap), I do not consider this a major shortcoming. of course, if you want to run something other than Windows or OS/2 (like Linux or even currently Win NT), the whole MWAVE appears to be useless... (in my opinion there at LEAST should be Win NT drivers!!!) -Todd =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Todd Tannenbaum email: tannenba@engr.wisc.edu Director of the Model Advanced Facility voice phone: (608) 262-3118 Computer-Aided Engineering Center FAX phone: (608) 265-4546 University of Wisconsin-Madison
