Why can't the envelope start middle way? with LFO as you see i was able to put a point middle way but with envelope it seems like it doesn't do it

 

Well some synths have both a positive and negative part of the envelopes so they do indeed start in the middle.. Most of the Yamaha romplers do this.So the Ex5, and the Motifs.

 

I have attached 2 pictures to you:

ADSR The most common kind of envelope generator has four stages: attack, decay, sustain, and release (ADSR).

Attack is the time taken for initial run-up of level from nil to peak, beginning when the key is pressed.
Decay is the time taken for the subsequent run down from the attack level to the designated sustain level.
Sustain is the level during the main sequence of the sound's duration, until the key is released.
Release is the time taken for the level to decay from the sustain level to zero after the key is released.

While attack, decay, and release refer to time, sustain refers to level

 

but why can't the envelope start attack at the middle....you show only full attack as starting point in your picture


for example for Volume envelope

Attack shows how quick it will reach full sound from 0....

but can't i start sound at middle instead of 0 ?

thats why i am trying to put attack at the middle

More quickly
- The tone rises faster and can be heard earlier.
- Good for plucks and drums. Makes the attack harder.

Slower
- The sound rises more slowly and can be heard later.
- Good for pads. Makes the attack softer.

ok i think its solved

the start volume middle way needs to be set up by the level knob of the oscillator.

 

As far as I can tell, with LFO you didn't put the start (first point) in the middle. You've put the second point in the middle. It is just that the first and second points occur at the same point in time.

If you move the first point, the endpoint of the LFO will also move.

Solution: change the LFO "mode" to envelope and draw whatever you want. (I don't use Vital much, but I guess it's similar to Serum)

 

With the 3 volume controls. you regulate the volume of the sound generator (OSC). You can use the volume controls to regulate the relationship between OSC 1 - OSC 2 - OSC 3. If the OSC should sound louder, the OSC 2 should sound quieter, OSC 2 and 2 should be in the background. It is best to start with OSC 1 and when the sound is there, work on the next OSC. OSC 3 can also be used very well as a sub-bass.

 

One can many times depending on the synth or modulation vst tool change the phase of the LFO so that it begins on the rise or any other point of the waveform that you so desire.
