Installation is very easy, provided you have a computer running Windows 98 ... or DOS. The majority of sound cards is recognized, but the Soundblaster 64 is not supported. SB16 and SB Live and affiliates operate without problem.
There is almost nothing to configure, once the software starts, it is ready to use. on the other hand, back side, make sure to have active EMS memory otherwise not be able to upload large files.
As for the manual ... the software comes with a few text files, but not exhaustive enough to get started. To learn, it is better to recover music files (modules) and see how they are made.
I have a Pentium 150MHz with a 64MB RAM Windows 98 SE, with a sound card as SB16. It works well, a condition not to launch disk access during playback: sound card then starts to sizzle, but just reset it with Ctrl + I, so that this problem is not really embarrassing.
The performances are perfect. I have never encountered any polyphony limit in size or open file.
The software is very stable, the only way I know to do is to ask freezer to calculate the duration of the music being edited and the file contains an infinite loop FadeOut.
I use it for 10 years, and I am always surprised by the possibilities. The fact that the software is fully controllable from the keyboard makes it really nice to handle. The major weakness of this software is that it runs under DOS. However, there is a perfect clone (schismtracker) that runs on Linux and Windows.
Second negative point, the software does not have a renderer to a wav, forcing a move by another software to make a CD.
It is a tracker: the music is entirely based on samples (contained in the project file) which is quite limiting when you have got used synthesizers. The effects available are very limited (no filter, no echo) and must be applied to each channel separately.
However, I have not found other sequencer interface is also convenient, which is reminiscent of hardware sequencers.
