Question about BT-4 and using a volume pedal
-
Hi, I'm thinking about getting a BT-4 and a volume pedal -- but I have a question.
Will the volume pedal adjust the "master' control on the modeled amp (in IOS BIAS FX or BIAS AMP), or will the volume pedal adjust the output signal level (that is, not changing the sound of the modeled amp.)
Thanks!

Actually you can use an expression pedal to connect into the BT-4
I'm not sure you can connect a volume pedal into BT-4
Once you do that in Bias Fx you can add in the signal chain the "volume pedal" and assign it to your expression pedal with a CC midi number
Then the behaivor of the volume pedal mainly depends on where you place it
Before the amp it works like a gain control (think to your guitar volume knob)
After the amp it should work like a master volume control.
In any cases there won't be any changes to the master volume knob setting of the modeled amp nor the master output level of Bias FX
Hope this helps
P.s.
Of course you may use a classic volume pedal between your guitar and your audio interface..and it will work as a gain control

@salvatore-di-piazza thanks - I should have been more careful and said expression pedal -- and thanks for the tip about placement.
Do you think using the expression pedal as a volume pedal would address the issue in the other thread about removing the noise that happens when switching between presets? Or, since the volume pedal would be "inside" the preset, we'd still hear the noise when switching?
One other idea - what about putting a true volume pedal between the audio interface (iRig HD 2) and the amp? That would allow pulling the volume back to zero before switching patches?
-
the noise could be something related to the electric current flow due the hardware you're using (audio interface, guitar, power supply) or it could be just related to the software itself.
In order to esclude the first possibility you shoud do some tests:
1 - try different guitars (humbuckers instead of single coil for example)
2 - try different audio interface
iRig HD2 relies on analog connection. Most probalby this is the reason why you get the noises you mention. Try a lightning/USB audio interface instead3 - try different power supply
Is you iPad connected to a power supply? try without it4 - keep the volume of your guitar to zero and try to change preset. Do you still hear noise?
5 - if yes disconnect your guitar from the audio interface and try again
6 - still hearing noise? disconnect your audio inteface and try again
7 - at this point if you are still hearing noise I would say that it depends on the software and add a virtual volume pedal before or after the amp in bias fx won't solve anything
8 - the better thing you could do at this point would be to adding a volume pedal between the audio interface and the speaker monitors.
BUT, If you need the volume pedal only to avoid the risk to hear those noises when changing presets, I would recommend you to buy a "mute switch" or something like that, it would be more handy and fast...Anyway keep in mind that if you listen from the "headphones out" of your iRig HD you'll need a stereo switch or a stereo volume pedal. Don't forget also to take note of what kind of impedance you need just in case you want to buy a volume pedal
point eight sounds too tricky and complicated to me. I wonder if it does worth...I bet that buying a lightining/USB audio interface and get rid of the iRig will solve all your troubles =)

@salvatore-di-piazza thanks for this detailed list - some of these I’ve tested, some I had not thought about. (The iRig HD 2 has a lightning connection to the iPad).
Another thing I’ll test, the headphone output from the iPad, to see if it shows the switching noise also.
And , just for anyone reading, the noise when switching presets is sort of a ‘whoom’ noise, as opposed to say, a ‘pop’.

Ok, So the hd 2 has a lightining connection, I forgot that :)
Would you record a short video for us showing the noise you've talking about?
plus, I think you could test the virtual volume pedal in Bias fx without necessarily having an expression pedal connected to the BT-4
-
@salvatore-di-piazza Well, I just tried uploading a video showing the noise when switching in BIAS AMP, but I got a message that I don't have enough privilege for that action.
But, I can also tell you that I experimented in BIAS FX with putting a virtual volume pedal at the end of the chain in two presets, and set the volume pedal all the way back to mute -- and then when switching between the two presets, no noise!
(Putting the virtual volume pedal at the beginning of the chain, the noise was still present)
So, I'm going to try a physical volume pedal. That will also allow me to moderate presets that are different volume levels.
-
@salvatore-di-piazza An update - I put a volume pedal in between the iRig HD 2 and my amp, and I'm very happy so far with the results. The volume pedal not only lets me silence the noise of switching between presets, but also lets me adjust to different volume levels between presets. And, I can also use the guitar volume knob to affect the amount of breakup in the amp preset. Looks like a very workable solution.

Yup. Sounds cool. I'm glad you've found a solution!
