Pitch Glide not working in Parallel Path (Channel B)

Hi,

 

I'm using a POD HD Desktop with FBV II foot controller.

 

I have an effects heavy patch and I want to move the pitch glide (Whammy) from start of chain into parallel path with no amp.

 

Chain is this:-

 

Q Filter (fixed wah) - A/B splitter ->

 

Channel A --> Screamer --> Classic Dist ---> Dealy w/mod ---> A30TB --> Mixer Left

Channel B --> Pitch Glide ---> No Amp --- Mixer Right

 

Mixer Output ---> Reverb --> USB Output

 

Previously Pitch Glide was following Q Filter and before A/B Splitter. On/off is set to EXP Toe switch, Exp 1 controls pitch.

 

Problem:  When in parallel path there is no effect - the pitch glide does nothing like it isn't there.  Mixer is set to 0dB 100% Right. Input 1 = Guitar, Input 2 = Mic, trim pot down.

I also notice there is no "Single Volume Control" in channel B AMP settings display panel - it shows all controls (Drive, Bass, Middle etc)

 

Any idea why this isn't working?

    In addition -  I can't add an AMP Sim in channel B because it hits the DSP limit.

      You need to set input 2 to also be guitar, when you use dual paths input 1 goes to top path and input 2 goes to bottom, at present the pitch glide will only be affecting the mic input.

       

      It would be easier if you could set it to a proper mono input structure but at present I believe this is the only way to do it

        Hi Sidysm, 

         

        Thanks for your reply.  If I understand you correctly,  the A/B splitter DOES NOT IN FACT split a Mono signal into two? If true then it's presence seems irrelevant.

         

        Does this represent the TRUE signal path in a POD HD (regardless of Input settings):-

         

         

        Input 1  --> Mono Signal Chain to Mixer Input Left/A --> Mixer Output Channel A @ Left Stereo Pan Setting

        Input 2  --> Mono Signal Chain to Mixer Input Right/B --> Mixer Output Channel B @ Right Stereo Pan Setting

         

        So if both Mixer channels are centered you get a stereo output albeit centred in the stereo spread. You only get mono if you put a true mono FX after the mixer?

         

        I may raise this as a different thread - because other Line 6 advice says use Guitar/Mic-Off  to stop amps/FX overdriving. So there's a big conradiction here.

          I have a separate post over on the thread here that takes the manual information.  It might be worth chewing through that --> http://line6.com/support/message/356211#356211

           

          It includes the following key statements  ...

           

          • In a configuration with no Amp or FX Blocks in Pre, Input 1 is fed only to Path A and Input 2 only to Path B. Therefore, this is the best configuration if you want to retain discrete Input Sources into Paths A & B.

          • Placing an Amp Block or an active mono FX Model in Pre results in a “mix-down” of Input Sources 1 & 2, feeding the same, combined signal into each Path A & B.

           

          It goes on to say about FX

           

          • ... some Models (all EQs, Wahs & Volume, and some Modulations, Filters, Pitches and Delays, as well as the FX Loop) preserve a stereo output within the signal chain, while others (all Dynamics, Distortions, all Amps & Preamps, and other various Models) are mono FX and do not.

           

          The trick then is to find a suitable effect to use as your splitter.
