1) GrooveMixer Download
This is a versatile, simple to use and learn little program with a lot of different options. It is a great choice if you a looking for a simple beat maker. more The file is about 5 MB in size and comes with a few per-loaded samples (909, 808 and Linn) and you can add more samples with relative ease. My only problem with it is that there is no kind of piano roll making it virtually impossible to put any kind of melody in your project. In all fairness I the program was not created to be a full service DAW, just a beat maker. My top pick for free beat maker.
Pros: plenty of options, great for making beats.
Cons: No piano roll. no option for 1/2, 1/4 1/8 or beyond snapping.
Here is a simple demo tutorial:

2)Beat Maker Download
This program was close to top pick but lost out because of no playlist feature meaning you can only make an 8 bar beat and not a full song. Other than that this app is loaded with features and even has a cool virtual pad drum machine if you want to mess around with a virtual drum kit.
Pros: even more features and different things to do than GrooveMixer. Simple Piano Roll!
Cons: No way to make a full song with multiple beats. Pre-loaded samples in pattern maker.
3) My Beat Creator Download
My Beat Creator is kind of like Beat maker minus a lot of the cool features (drum machine etc.)
It does have a visually stimulating blue user interface and is very straight forward with some basic features. If you are looking to create simple, one pattern beats fast without any hassle this is the program for you.
Pros: simple, easy to use and pretty.
Cons: Very few features and only one pattern. Pre-loaded samples.
