This hoover tutorial was requested by d_b. I finally got time to do it. I hope its helpful.
History:
The 'hoover' was first used in the track 'Mentasm' by Second Phase (1991, R&S). 'Second Phase' was a collaboration between Joey Beltram and Mundo Muzique. The mentasm sound was taken directly from the Roland Alpha Juno-2, it's a factory preset on there called 'What the...!'. Then, according to beltram himself:
We edited the shit out of it, sampled it in another keyboard I own and proceeded to edit it some more (that gave it the extra punch that the alpha didnt have). Thats why nobody had ever been able to duplicate that sound quite like mentasm and thats why it has that deep sub in the midle and acid filter parts toward the end, we were no longer working with the alpha.
Thanks to Rounser for that quote. Scroll down to his post for the full text
Later on, Human Resource used a similar sound in their track 'Dominator'. This was the beginning of a trend, and lots of people have used the hoover sound since.
There is no right or wrong name: hoover or mentasm, but a 'mentasm', or rather the mentasm, is now generally considered to be only the sound sampled from the track 'mentasm'. Whereas 'a hoover' is a broad name for the type of sound, synthesized or sampled.
No matter what anyone tells you, 'Hoover' is not another name for a reese. This is something else entirely and is commonly confused.
Some hoovers:
Second Phase - Mentasm - audio
Human Resource - Dominator audio
English Muffin - Blood of an english muffin - audio
Prodigy - Charly rename to wav
Technique:
Its basically 2 PWM Saw-waves, which is a piece of piss to make in reason
Create a subtractor synth, enter a longish C3 note on the sequencer, loop and press play.
Starting from the Initialize patch, make the following changes:
Osc1 phase: 127
Osc1 phase-type: subtract
Osc1 waveform: saw (|\)
-----
Lfo1 sync: on
Lfo1 rate: 2/4
Lfo1 amt: 127
Lfo1 waveform: triangle (/\)
Lfo1 dest: phase
-----
Mod-env decay: 56
Mod-env gain: 40
Mod-env dest: osc1
----
Filt-env att: 59
Filt-env decay: 57
Filt-env amt: 0
----
Velocity f.env: 0
----
Ok, thats the basic patch. The filter envelope isn't doing anything just yet.
The key ingredient here is the 'phase' knob. By turning this to the right you are creating a duplicated and slightly delayed copy of the wave. So, in effect you have two saw waves, but the subtract or multiply options add them together in different ways (refer to the manual for details). The LFO is modulating the 'phase' (delay) between the copies. This is similar to an effect called 'pulse-width modulation (PWM)'.
PWM is the squashing and stretching of the gaps between a pulse/squarewave over time. Its called 'pulse width' modulation because you can only usually do it with pulse-waves on most synths, but with the subtractor and the juno you can PWM saw waves.
The Modulation envelope is causing that big decaying drop in pitch. You could just set the amount to zero and automate the pitch wheel instead (which is more flexible).
Ok, cool. Now, Usually on all good hoover sounds theres a little 'Woaaw' sound in there, this is how i do it...
1) Click on your synth
2) Create a 'PEQ--2 Parametric EQ' as an insert (Chain should be: Synth > EQ > Mixer)
3) Eq settings: A-freq:39, A-q:48, A-gain: 59 | B:eek:N, B-freq:20, B-q:103, B-gain:33
4) Create a Spider CV splitter/Merger
5) Press TAB and flip over to the back
6) Take the 'Filt Env' CV-out and plug it into the 'split A cv input'
7) Take 'split A output 1' and plug it into the 'Freq1' CV-in on the EQ
Take 'split A output 2' and plug it into the 'Freq2' CV-in on the EQ
6) Adjust the 'Freq1' & 'Freq2' CV Levels (knobs just below the input sockets) to 38
After your EQ put in a CF101 chorus to thicken up the sound
Delay: 95
Feedback: 0
Rate: 2/4
LFO sync: on
Mod amt: 40
Muck about, resample, put in a NNXT and play with the pitch envelope and pitch wheel.
It'll never sound like a juno, but its still a nice hoover.
Post your own techniques, comments, criticisms, and questions...
