I have not read the manual because the interface is super easy to understand and implement.
As against small problems with this app, with four instruments it pumps a lot of CPU I have a 2ghz athlon 64 and 1.5 gigabytes of ram.
After all it is stable so it is trs satisfesant.
I use it for about 4-5 months
The sound is average; correct for the freeware;
The system is perfect 16 instruments at the same time a voice noon (one per channel): this is very practical
Despite some default level processor, I exchange it for anything.
