Function of Envelope view parameters

Software Instruments Pure LoFi
#1

In the manual, in 3.14. Main panel Advanced view, (p.44) there is a velocity %.

In the Envelope view, there is a velocity % (velocity>time, key>time).
I haven’t been able to tell exactly what they do.

It seems that key>time % (eg. 75%) acts like keytracking on the envelope. Higher notes seem louder. I may be hallucinating.

Hi @francoise ,

From the manual:
5.2.4. Envelope MIDI modulations

  • Key > Time: Envelope times (attack, decay, release) become more sensitive to
    keyboard note
  • Velocity > Time: Envelope times (attack, decay, release) become more sensitive
    to MIDI velocity
  • Velocity > Amp: Scale parameter becomes more sensitive to velocity

However there is a bug since the ATTACK TIME is’nt affected like it should.

Thank you LBH,

I read this part but I couldn’t clearly feel the change.
It seems that Key>time is keyboard scaling: higher notes are louder than lower notes when set at 70% (or more).
Since I play chords with left hand and melody with right hand, it’s an important setting.

Sensitive= speed at which the cursor moves on the envelope.

Disabling Velocity>Amp (0%) and velocity>Time (0%) and setting Key>time to -100% changes the speed at which the cursor moves on the envelope. With very low notes, the cursor will move more rapidly than with very high notes. And vice-versa set at +100%.
And Attack is not modified as you point out.

Same with Velocity Time set at -100%, on high velocity, the cursor moves more slowly and vice-versa.

I don’t see much difference with Velocity>Amp.

Hi again @francoise ,

  • Key > Time:
    This mean the note you play affect the time it take for the envelope curve to go from one point to another. The speed.

  • Velocity > Time:
    This mean the velocity you play affect the time it take for the envelope curve to go from one point to another. The speed.

  • Velocity > Amp
    This mean the velocity you play affect the scale for the envelope. The amount sent out from the envelope so to speak. It amplifies the Scale parameter.

All the percentage parameters can be set to both negative and positive values.

The effect you will get out of it depend on which parameter/s you modulate.
Keep in mind that each modulation you create can have it’s own modulation amount setting too.

You also have a Velocity setting for the main AMP envelope. This will affect the main output from the VCA.
If the setting is 100%, then the velocity control full level range. The maximum level will stay the same no matter the setting.

I hope this helps.
