Topic: Inaccurate VST controls

I need to precisely set the values into my VST interface (I’m working with an Eigenmike32) but they only change by more or less regular steps, so I’m unable to get the desired value. Is there a way to get a more accurate control over the knobs or, even better, a way to numerically enter the desired values?

I’m guessing the plugin you are using doesn’t have its own editor, but instead uses the Podium native editor interface. If that is the case, then you can hold the Shift key down while clicking a parameter dial, to fine adjust the value. There is currently no way to enter a numerical value in the Podium native editor interface.

Can you tell me whether there is a way to directly modify/edit values inside a fxp file containing presets for my VST?

The fxp file is a binary file and not a text file, so it will be very tricky to modify the fxp file directly. You’ll need a binary utility tool and some knowledge about the structure of an fxp file.

This is the code for the fxp header format I use in Podium:

	// Based on fxProgram from vstfxstore.h in VST API

struct VstProgramFileHeader {

ULONG_BE		m_FileMagic;

ULONG_BE		m_ByteSize;



ULONG_BE		m_TypeMagic;

ULONG_BE		m_TypeVersion;

ULONG_BE		m_PluginID;

ULONG_BE		m_PluginVersion;



ULONG_BE		m_NumParams;

char				m_Name[28];							// Null-terminated.



// m_TypeMagic == 'FxCk':

// float_BE m_Params[m_NumParams];



// m_TypeMagic == 'FPCh':

// ULONG_BE m_ChunkSize

// UBYTE m_Data[m_ChunkSize]

};

Whether the data is stored as an array of floats or an unspecified chunk of data, will depend on the plugin.
