OK.. here's a list of the known problems - I'm working on them, so unless you know how to help... please don't write to me about it! 1) Apparently, many problems have been encountered with QEMM... I really don't know what's going wrong here at the moment (I haven't had any experience with QEMM myself), but try using the following line in your CONFIG.SYS file. If this still doesnt' work, I would recommend that you steer clear of QEMM if possible for the meantime. DEVICE=\QEMM.SYS DMA=64, HANDLES=255 2) With the GUS, 16-bit samples > 256k will *NOT* be played correctly. This is due to a 'quirk' of the GUS - something that I don't know how to easily fix. This does *NOT* occur with 8-bit samples. (This is the same problem that you'll find in FastTracker II also) 3) Some MODs/S3Ms won't sound quite correct if they use G00 commands after Exx or Fxx commands, because in Impulse Tracker, the 'memory' for Exx, Fxx and Gxx are linked, whereas this is not so for MODs/S3Ms. Also, S3M also links Exx and Dxx (I *THINK*) whereas IT does *NOT* 4) The "Active Channels" indication is *NOT* always 100% accurate (it's even affected by stuff played in muted channels.....) Also, on a GUS or AWE32, the program requires the hardware to provide the 'end of note indication', whereas the mixing routines are calculated internally... hence, if the hardware provides the indication a little later than expected, another channel is allocated - what this means is that the value as played on wavetable cards *MAY* differ from the value played on software-mixed cards. This difference is minor (ie. 2 channels at most, unless you *TRY* to setup a special situation) 5) There is no 'enforce Amiga limits' option in IT (Which was in ST3) so pitches of notes exceeding the Amiga limit will not be suitably played. 6) If your system behaves unexpectedly in IT, it *MAY* be necessary to specify the complete parameter list on the command line. This should NOT be a problem in most cases, but it has been known to occur. 7) In Windows '95, if you shell to DOS when using SB on a high IRQ, then playback may stop! I've got no idea as to why this happens, but it seems to restore itself after loading another module (on a SB16) 8) Loading a MMTSRed sample/module in Windows '95 can screw up some/several samples if the song is playing. This seems to be a problem of Win95!
