Minimal Instrumental Hiphop SegueMP3 | WAV
Sparse, minimal downtempo breakbeat and a Moog-ish bassline. This clip is only 34 seconds long so it would have to be a segue, incidental music or music cue.
Too Cool for HomeschoolMP3 | WAV
This track starts with solo turntablism filtered with light delay. The beat drops-- a simple, crisp drum-machine breakbeat with sub bass. The beat is then filtered through a flanger while the turntablism continues.
Filtered Breakbeat with Clav SoloMP3
The main solo on this track is performed with the Native Instruments Elektrik Piano Clavinet (along with some filtering effects). The breakbeat has a lowpass filter using Ableton Live's built-in Auto-filter effect.
I'm trying to use the first track with the Moog bass line on a track. I'm not that musically knowledgable, and I'd like to know what notes are being played in the bass line so I can match it.
