how do i set a pre-delay for reberb using DH_Reverb 1.1+ ?
I know that pre-delay is the time between the first dry signal and the first sonic reflection, and at first i used a delay after the Reverb with a dry/wet funtion but i believe this is not correct?!!
Doesnt the delay must only create a sonic reflection instead of all signal together after "some" time?...i mean..this sonic reflection is just the first part of the Reverb reflection and does not contains the dry signal, no?!!
So if this is correct (cause im not sure) how do i create it?

Thanks Rob. I believe this must be done with some sort of Sample and Hold but for audio not voltage. I think this way i could separate the Reverb reflection from the dry signal. I must ask someone who already made one.
Thanks again boss.

I was thinking about using a CK envelope with a exp. root shape or so for attack.

i never saw such thing...i do not use CK modules cause i never had money apart to buy them. could it be possible with anormal ADSR? i mean... i can trigger the gate as i want... There is a DH module for time trigger gate. I can trigger at the same time the sound enters and maybe grab just a bit of it to input in the reverb.
Would this theoricaly work? or maybe not cause i have t separate the whole sound to set up a start point for the reverb. : S

Am not sure it will work with a Envelope/ADSR, the idea is to use it to variably silence the beginning of a sound. I proposed CK his envelope due to the shapes it offer, maybe the normal could work as well but the shape of the attack will probebly not be sharp enough.. Do note that I never tried this, it's just an idea i have.  When I got time I will test it ok. |

ok boss, i will test the alternative theory with a normal ADSR to see wich effect i can achieve. Thanks. |

Hey Rob, could you check this prefab for me? this is what i came up with... i just wanna know if it is a pre-delay to you, im not familiarized with it.... anyway even if its not, im gonna apply something like this in my Reverb plugin, it sounds cool even if is not a pre-delay. Predelay test.zip (5.71 KB) Thanks: Duarte V. |

Duarte, Build your test like this, it's not 100% correct but seems to work while changing the duration between 0 and 200+ ms or so. Try it.. What you made didn't work with the trigger module from DH, when I pressed a note several times the reverb started working.. not at first note pressed. -> Envelope out from DH_EnvSeg goes to VCA Volume in. -> Loop should be set to: 1. -> Shape used: S-curve. Requirements: - DH_EnvSeg- DH_msToVoltageScreenshot:  |

Think this could be improved, need to think some more about this.
What just needs to happen is to delay the volume of the VCA from going from 0 to 10 Volts by X amount of ms.
Maybe just use a delay2 module + AND gate or so. Then maybe the envelope module can be removed.
To be continued!

This works when a note is pressed once, but it doesn't return fast enough to 0 Volts so if you'd press notes fast it fails to predelay it correctly. :/  |

Ok Rob, i will try the first example. Even if is not 100% it is better than what i had till now ... Thanks for your effort boss. Well, (editing) ... i want to make a plugin not a vsti, so where do i connect the gate of DH_EnvSeg? I believe i must use the DH trigger module anyway... gonna see if works |

OK...i tried both examples you gave.
example 1 does not seems to release any kind of reverb, i tried long enough samples but they always sounded dry, even pushing the size, damp and mix of the DH reverb module to the maximum.
example 2 seems cool, even with the no return to 0 volts fastly, i just do not know is where i connect the voice combinner when creating an fx plugin instead of a vsti. I never set MIDI2CV in my plugins. Is this a correct procedure? and if i do set, i have to connect the MIDI IN also, isn´t it?
I´m confused ...sorry!

Let me try to rework them with the dh trigger module then.

Doesnt the delay must only create a sonic reflection instead of all signal together after "some" time?...i mean..this sonic reflection is just the first part of the Reverb reflection and does not contains the dry signal, no?!! So if this is correct (cause im not sure) how do i create it? You wrote that You put the Delay AFTER the Reverb? It has to be in front of it, hence the name "Pre". To make a good predelay (simulating walls at different distances) You could hook up 6-8 delays with different times. If You search for BBD(Bucket Brigade Delay)-chips, some examples of good times to setup in the delays can be found. Use one (mono) or two delays (for stereo) to create the predelay and the remaining 6 for simulating Early reflections. Combined with DHs Reverb, it can be set to sound pretty amasing. One other trick to use, to avoid "ringing" reverbs is to randomly and very subtle "wobble" the input signal by volume and/or pitch, i.e. slight chorus, barely audioble, but enough to "massage" the reverb. Hope some of this was usefull. Best, Claus |

Btw. I should point out that to make a more refined simulation, You'll need to feed each delay back to a single input that then again feeds all the delays and so forth. But You will need the SE feedback module to sum the wires, before feeding the input again.

I saw some diagrams about the delayed feedback system in google... i think im understanding this, but i thought that pre-delay reverb meant that longer it was the delay, later the reverb would trigger, making this way a small dry signal on start and a reflection considering the start point of the reverb over the sound affected.
Anyway..
Lot of Thanks... i will get back to this later.. in the meanwhile i started some other projects and i will leave this one for later cause im thinking on creating a pack of special plugins where i want to include this technique.
Appreciated bros.

Oh, forgot to mention that the predelay is placed between the 6 BBD-like ones and the Reverb itself. It works somehow  Ahh, okidokey |
