How do I play and loop my giga format drum samples without a keyboard? Do I need software or hardware? Do I need a sampler or sequencer? A midi keyboard? Is the capability already in my software? I've done some drum programming (in standard music notation) in Cubase. I have a MusicXPC S3 with the following software and samples:
GigaStudio3 Ensemble
Cubase Studio4
Encore
BandInABox
LarrySeyerAcousticDrums
LatinGrooveFactoryBrazil
SteveGaddDrumScores
DS SoundwareUltimateOrchestralPercussionSampleLibrary
ChristianLaneUltimateMarimbaandVibes

Where to start?
