Attack Decay Sustain Relase
in analog circuits it used to be a bit of fun
since computer chips came of age its all in how you feed the D/a convertor on the output jack
a lot of the new stuff uses sampled sounds from real instruments
ADSR stands for Attack, Decay, Sustain, Release. It is used to describe the envelope or shape of a sound wave over time. Specifically, it defines how a note's volume changes from the moment it is triggered until it fades out.
You can increase the efficiency of VST by using the following methods. 1 - Use fewer Unison Voices - Each unison voice creates a replica of the original signal, which means double the work. Try to use a low unison voice value. 6-9 is good. 2 - Use modulation wisely - Modulation is automated automation; the more the number of modulated parameters, the more will be CPU used. 3 - Choose the plugin wisely - You can make a basic pluck simply by using a saw wav and a Low pass filter with an ADSR envelope, for this purpose using a High Spec VST I not necessary. 4 - Avoid Plugins with heavy RAM usage; like Kontakt libraries with high sample rate and storage. 5 - Get presets for plugin with low specs - like ANNMS Music, you can find presets for plugin like GMS, Toxic Biohazard, Harmor etc. These lugins are very efficient and the presets are free.
my best bet would be either a Gary hurst mk 1 modified by roger mayer or a Gary hurst mk2...again, modified by roger mayer... regarding the mk 1, i doubt that very much was done to it...however, i have been able to replicate the "you shook me" fuzz (including that crackling 6 string bass note) by changing all transistors to silicon, modifiying the input bias network and installing a diode to change the input characteristics...this would have been a diode that would be switched in and out to requirement... clearly, there are overlapping parts to the song where either two fuzz boxes were used, or some kind of gating effect was brought into use as a means of controlling noise...during separate overdub sessions... the amplifier referred to as being used by page was a supro, yes, but not the one as stated...i have maintained this position for years... add in the mysterious eq technique (aka "Q mapping") and with a couple of hours of experimentation, one could come extremely close to the "you shook me" sound...additionally, some of the adsr circuits could add overtone harmonics and a slight buzzing effect during decay of the guitar note... hope my input has been helpful... hingethunder64@yahoo.com
