BuckeyeTodd Posted March 12, 2017 Share Posted March 12, 2017 My volume pedal has no in between volume, it's either full on or completely off. When I set the block up, you can see it showing a gradual increase on the graph, but there is none when actually using it. Any ideas how to fix this?

timmyo Posted March 14, 2017 Share Posted March 14, 2017 The volume pedal block defaults to linear - change that to logarithmic and you will get the smooth change you are looking for. Volume pedals (and indeed guitar pots) usually have log pots in them - no idea why the volume block defaults to linear :-/ Quote Link to comment Share on other sites More sharing options...
jbuhajla Posted March 14, 2017 Share Posted March 14, 2017 Linear will change from 0-100% in a constant slope (linear) change. Logarithmic also changes from 0-100%, but the change is a curve and not a straight line. Either way, it should not make a sudden jump from 0 right to 100. I would try deleting that block and drop in a fresh one and don't change the default settings. It will default to EXP2. If it still jumps, then there is an issue.

PeterHamm Posted March 14, 2017 Share Posted March 14, 2017 Do you have a compressor after the volume pedal? If so, switch their position if you can. Quote Link to comment Share on other sites More sharing options...

Yes the *value* changes smoothly, but the way the ear perceives loudness means that for a linear *sounding* increase in volume the pedal needs a *logarithmic* sweep. Try it, you'll see what I mean.

FlyingsCool Posted March 14, 2017 Share Posted March 14, 2017 Also, try changing the location of the pedal in your change. If you put it before your amp, it's acting like your guitar's volume knob, and, for a lot of amps, pretty much just controls the tone, not the volume. If you place the pedal after your amp, it'll act more like a volume pedal. As the previous poster said, logarithmic is closer to the way the ear perceives loudness. I like to place mine after the amp and before the delay and reverb(s) for swells and such. Quote Link to comment Share on other sites More sharing options...
BuckeyeTodd Posted March 14, 2017 Author Share Posted March 14, 2017 I just received an email from Line 6 about this... "When a volume is in the signal near the beginning, the range of the "throw" is diminished due to the lack of dynamic range and compression introduced from the amp model. If you want to change that, move the volume pedal block to the end of the signal chain." Quote Link to comment Share on other sites More sharing options...

I'm going to move it and see what happens, thanks Quote Link to comment Share on other sites More sharing options...
tagmusenmagnus1 Posted March 14, 2017 Share Posted March 14, 2017 I actually use two block to get to the right sweep. I have two in series both set to Log - this way it gets near the sweep i want... not perfectly, though. Quote Link to comment Share on other sites More sharing options...
HonestOpinion Posted March 14, 2017 Share Posted March 14, 2017 ... I like to place mine after the amp and before the delay and reverb(s) for swells and such. I also place mine after the amp/cab and before any delay, reverb, or even mod effects like chorus that have a delay. That way the trails don't get cut off prematurely if you crank down your volume via the expression pedal. Quote Link to comment Share on other sites More sharing options...

FlyingsCool Posted March 15, 2017 Share Posted March 15, 2017 One other issue I did once was I accidentally set up the expression pedal as a footswitch on/off controller. :o Clearing it fixed it Quote Link to comment Share on other sites More sharing options...
duncann Posted March 15, 2017 Share Posted March 15, 2017 If your using Helix in a studio setting, using midi to change the expression controller provides for much more accurate, customized, and repeatable volume control. Quote Link to comment Share on other sites More sharing options...

Yep I agree - whenever I forget to change it to log I realise because it sounds like all the change is coming right a the start of the travel t Quote Link to comment Share on other sites More sharing options...
FlyteBand Posted June 22, 2021 Share Posted June 22, 2021 Very helpful, I have been using my Ernie Ball volume pedal externally first in chain for nice gradual swells in volume. I was unhappy with the instant volume on Helix. I will try these recommendations this week. Thanks. Quote Link to comment Share on other sites More sharing options...
