Why don't you try Cubase ?
Acid is a great application, but for the "serious work" I think programs like Cubase or Logic have alot of more interesting features.
Cubase is a very decent sequenser, completely multi-track, with great MIDI ánd AUDIO editing features. Ánd you have all the plugin features, of course. And decent mixing panels, with EQ features, FX, ...
And Cubase has with his "ReWire"-technology an automatic link with programs such as "Reason" and "Rebirth" (that means you can control the BPM from within Cubase, and you can put all VST FX from Cubase on the Reason or Rebirth channels - yes there are seperate mixer channels in Cubase for all sub-parts of Rebirth/Reason).
You could operate from within Cubase things like the BPM of your drummachine, and you could record within Cubase the drum stuff on one or more stereo audio channels (I mean the BD, HH, SD, etc. all seperately).
