Bypass

[aztekdesigns]

I was wondering how to make a simple Bypass button for a effect, when I click the button it will bypass the entire plugin. I know its probably a simple question but I am new to DSP!!

Cheers,
Aztek:)

do you already have a plugin working? Bypass would be just simply don't do any handling of the audio data.

Yes just a simple Graphic EQ, ok but still need an idea on how to do it.

I found this code in the Steinberg SDK,

//-------------------------------------------------------------------------------------------------------
/// \name State Transitions
//-------------------------------------------------------------------------------------------------------
//@{
virtual void open () {} ///< Called when plug-in is initialized
virtual void close () {} ///< Called when plug-in will be released
virtual void suspend () {} ///< Called when plug-in is switched to off
virtual void resume () {} ///< Called when plug-in is switched to on


Would this be what i was looking for?

No, those are events called by the host. You override them to react to the changes.

If it is your own plugin you want to suspend.. Well, you create a button that toggles a boolean. Inside your processor method, if the boolean is set, you merely copy the contents of the inputs into the outputs (effectively bypassing). If not, run your active code.

In your ProcessBlock you can do something like this...

Code: Select all

if(numChannels < 2 || MasterBypass)
{} // Passthrough
else
{ // do processing

float* leftData = buffer0;
float* rightData = buffer1

for(i=0; i<numSamples; i++)
engine(&leftData[i],&rightData[i]);

}

Cheers that worked and was nice and quick
