"As you can tell, this is a very specialized version of this classic drum machine. This 909 contains modifications (thanks to Colin Fraser) to the kick as well as the high-hats, to give you far more flexibility that what is traditionally offered by a typical 909. The mods to the kick are the group of three rotary controls above low/mid Tom controls. As you can see, the same rotary knobs that were on the original were used on the mods. Mods to kick add three new controls:

- Pitch: controls the frequency of the bass drum oscillator
- Drive: allows waveform adjustment from normal to square, for hard clipped sounds
- Tune Depth: varies the amount of the initial pitch sweep (decay is set by TUNE control)

These mods literally give the 909 the ability to produce any kind of kick imaginable, from overdriven, to deep, pulsating kicks. I've posted 5 minutes worth of nothing but these modified kicks on Youtube - this is just the tip of the iceberg. You could literally tinker with variations to the kicks for days.

The hi-hats mod gives a tune control for the hi-hats that functions the same way as the tune controls for the crash and ride cymbals. This adds a lot of depth and flexibility. Youtube video with sounds of the Hi-Hat mods can be found here:
