Getting a pitched drill sound

[tpantano]

Any ideas on how I could get a sound similar to an electric drill, very abrasive, but still with some frequencies to give it a pitch?

I've tried many different things with cross mod, vpm, noise, ring, sync, waveshaping, filter mod, lfo mod and effects, but I always spend a good 20 to 30 minutes on a patch before getting nowhere and not saving in a fit of frustration.

I think getting the harsh, abrasive characteristic of a drill will need some sort of very fast lfo modulation of something, but I can't figure out what. Also, a lot of saws to make it close to noise but still pitched.

Depends what kind of drill you're after too.

A hammer-action or masonry drill will have a definate regular 'thump' as it powers into the wall.
A dentist's drill is relatively quiet and will be more of a high pitched whine.

A drill in the room next door sounds more like a violent vibration (a bit like a mobile phone on a hard, flat wooden surface)

Probably amplitude (tremolo) and maybe filter cutoff as well. Probably need to add distortion and/or grain/decimator as an effect for the abrasive sound. Haven't tried it myself though, so these are just guesses as to how I'd approach it initially.

maybe I'm thinking of the wrong power tool, but that.

Hi,

well this would have been a good challenge fot the RPC

The first thing that comes to my mind with such a sound is the frequency. A drill goes from 0 to its work frequency in a short time (0,5 ~ 1 sec maybe?). Depending on the load (push force and resistance from the material being drilled) it's frequency may slow down and/or rise depending on that load. When the switch or trigger is released, the freqency drops to 0 again. What do we get from this facts? An envelope with attack high sustain (to avoid decay) and release.

The second fact the drill has a motor and gears, where the motor has a high pitch that is reduced by the gears, so it is a combination of different frequencies and waves that have something in common: they vary proportionally to the RPM in the same relation.

The third would be the bit in the material, which creates a grinning and scratching sound and the resonances that come from the material being drilled. Hmm.. this reminds me the movie marathon man, a simple but very effective effect with that dentist drill.

I think you will need to combine and synchronize all possible oscillators and LFO's to get such a sound. Good luck!

Here's what I have so far. Could easily be used in some nice industrial dubstep or something

Wow, that ia a good aproximation, tpantano. Now you could try to get more harmonics from it (maybe with the comb filter?)

well, I used a serial high pass to cut a little off the low end, which was too full sounding. But I could fool around with having filter 1 somewhere between high and low pass, then put in a comb.

Start with a low note, legato to other notes to change the pitch then end with a low note before release.

Today I've tried to make on R3 sync'ed lead from Laserdance's "Shotgun", but in the end I've achieved something faaar more interesting.

Hold lower E note on R3 keyboard and enjoy

You can also play with EG3 parameters to change character of this "rising".
