Midi Drum Editor

[Matt303]

Does anyone know of a cheap drum editor whic I can use for Midi drum editing. I dont want to do any sampling or sample playing. All I want is to be able to edit a drum pattern graphically on my PC and play it via a keyboard. I could do this years ago with Steinberg Pro 24 so I'm sure there must be something out there maybe even a bit of shareware. If possible I would like to be able to set up a midi map of the keyboard drum kits
