I downloaded a demo version of FL Studios Producer and am way impressed by it. Its totally free. The only issue with the demo copy is u cant save the stuff you are working on, and I have problems with Eq'ing once I am done programming. But, its got tons of cool gadgets on it, and a super human drum sequencer. There is a small learning curve but besides that I absolutely love the program. But, I use a 4 track too and with FL studio you can sequence a bus load of tracks and record em to the tape deck. Ive built tracks with upwards of 64 seperate parts before. Good luck !
