You might be able to get Native-Instruments Komplete Start to work ok. This has a heap of virtual instruments. Or look at Amplesound’s free bass and guitar (not as good as the paid for jobs but are ok). There are any amount of free sampled pianos and the like out there. Also many synths where one can create almost anything they want.

Just a thought
