Hi David,
it is a though job to make good drumparts. To my opinion one must have drumskills to make good variations. By Using steprecord it is of course possible, but also difficult to make a 'good sounding' drumparts. I mostly use midifiles to cut out/transpose drumparts. There are 'millions' on the internet. As an example you could try/listen to some of them on http://www.keso.nl . For instance 'Wipe out' is made with the help of an midifile.
Succes and I am sure that there are members which can help you with other ideas or suggestions.
Greetings,
Cees
