Can someone help with an envelope tremolo or rotary?

[rjclark]

Hey forum.  I used to use a Line6 MM4 and it had a feature where the the speed of the tremolo was based on the attack.  So when you would strum a chord, the tremolo would be very fast and then slow as the attack decayed.  I can't seem to find the magic values on my ModFactor.  I refuse to believe this think can't do it since already has everything it needs to do so, but…?

Thanks in advance for any help!

Hi rjclark, you should be able to to do this by:

1. setting the SPEED knob of the tremolo (or rotary) to your desired slow speed. 

2. Set the ModSource knob to Envelop or ADS

3. Turn the Rate knob (should be for sensitivity now) all the way up to 99

4. Strum a chord and set the SMOD to achieve your desired fast speed.

5.  Reduce the Rate (Sensitivity) to get your desired slow/fast sweep time. 

Does this help?

YES!  This is exactly what I'm looking for.  And this just opened up my eyes to how these lower row of knobs behave.  Thank you!

BTW, where in the UM does it specify that actual difference between Envelope and ADSR?  Do they act different?  If so, in what way?  I can't seem to find anything in the UM.

You're Welcome!

Yeah, the lower row of knobs is something more familiar to synth and keyboard guys, basically amplitude and frequency modulation.  DMOD  being amplitdue, SMOD being frequency.  But this row does allow for all the cool complex patterns that MF can do.  You can use it to build up cool rhythms in SQUARE wave chopping tremolos for example.

Also, ENVELOP and ADSR do act a little differently.  The envelope is a peak-follower, so it just follows a smoothed version of your input dymanics curve.  The ADSR is a pre-programmed attack-decay-sustain-release envelope that is triggered by your input sound.

How i make negative  modulation in Dmod or Smod?

Higher dynamic – little modulation depth or low speed

Lower dynamic – higher modulation depth or higher speed

It's possible?

Actually, that's not possible right now, but it's a good idea and totally doable, so perhaps we can do it in a update (if enough support is drummed up).  We could either be negative DMOD and SMOD values or add inverse envelope/ADSR shapes.  What would be more useful?

Thanks!

I wait for next FW update…:-)
