like old mobb deep or black cocaine???? alchemist beats are usually mainly sampled, from a wide variety of genres but he uses a lot of spanish records, which seem to have pretty good basslines. justch watch youtube vids on al you'll see what i mean.
otherwise any daw can produce a good bass patch, just take a simple sine wave and mess around with the cutoff/resonance a little bit and you'll have a basic, simple hip hop bassline. later on you can mess around with multiple oscillators and lfos to get more custom sounding shit
