Virus A LFO delay is there a function?

[lionelred]

Hi there
I was wondering if there is a way of delaying the lfo for it to swell in later rather than at the start of the envelope.
I have this function on my MKS 80 And Juno 106 but can't find it in the menus.

Hi there,

Just to clarify, you want to press a key and then have the LFO's intensity (modulating something like pitch or similar) ramp up slowly?

Unfortunately I don't believe there is a dedicated setting for that.

However you can fake it by:

1) Riding the mod-wheel manually to modulate the LFO, or..

2) Using aftertouch to modulate the LFO (pressing the keys down harder after note-on effectively controls the LFO modulation amount), or..

3) using a spare Envelope (Filter or Amp), if you have one available, to modulate the LFO intensity over time, or..

4) setting up another LFO (let's say LFO2) in one-shot mode to modulate the LFO1 amount over time.

Options 1, 2 and 3 are easiest, but 1 and 2 require manual operation, and 3 requires that the Amp or Filter Envelope is free for use (often they're tied up for other stuff which limits their use). That said, option 2 (aftertouch) is a really great, expressive method to use if your MIDI keyboard has aftertouch available.

Creating a ramp-up type effect using option 4 is more complex and not for the faint hearted as it requires exact knowledge of how the LFOs work including their contours and trigger-phases - for example, creating a one-shot upward ramp type effect will actually require using the triangle LFO waveform with an appropriate contour and trigger phase, as unfortunately the sawtooth waveform only works as a declining saw rather than a rising one. However I've found there's a tiny little glitch with the triangle waveform when you're using it this way, and to erase it you need yet another additional LFO.

A simple, delayed on/off modulation is much easier though (using a one-shot LFO using a square waveform) compared to a faded ramp-up type effect. It depends on the effect you're after.

If you want me to go in more detail explaining each step I will do. If so, let me know exactly what you're modulating via the LFO (oscillator pitch? pulse-width? others?) as well as the LFO amount, and the delay time, and if you want the effect to fade in smoothly, or abruptly.

There may be other ways to do it, but those are my first thoughts.

Hi..



what he is asking for....i think that is possible on LFO 3.....LFO fade in....

is that a way to do it?? to have the lfo fade in gradually...

try it...

:)

Lol....

Nutrino, you're a star!

I hang my head in shame. Gahh.

Bravo young sir. :)

Sorry to revive an old thread & that

I came here looking for info on how to put a delay on LFO 1 & 2 & now I'm kicking myself that I didn't figure this out for myself.

The Mod Matrix is your friend :cool:

too bad there are no logical modulators in the ModMatrix
