Varian Turbomolecular pump

A tubomolecular vacuum pump sampled and mangled into a pad....

The story

In one of the labs at work we have a tubomolecular vacuum pump that whines away at 75k rpm persistently.

I took a sample of this racket and attempted to make an organ pad sort of thing out of it.

The sample is played in reverse on the right channel, both left and right are detuned 4 cents apart and also start at a slightly different point in an attempt to create stereo width. Some filtering, saturation and reveb is added to make the sound a bit thicker and a flanger is added with a control knob should you want a bit more spinny-ness.


Leave a review to let others know what you thought of the instrument!

  • An interesting but limited sound

    A drone-like pad that you have to hear it yourself. It is quite chaotic and if you play more than 2 notes, it becomes chaotic very quickly. There is a little knob to make it more "spinny", which is like shifting its pitch up and down a little bit. It's interesting, but I think it has a very limited range of use. You might disagree though!

  • Average Sound, Great Name

    The sound, while not an everyday sound, could work well in many contexts. Enjoy!

  • Both deep and meaningful

    Not for everyday, but when you're having one of those "I need to blast myself into a vacuum sealed turbomolecular exploration of the cosmos" moments, this is just the thing.
