GIGAPULSE IN THE MIDI MIXER 

GigaPulse Convolution can be used to model environments, instrument bodies, signal paths, 
digital reverbs, and pretty much anything else you can send audio through. It is up to the library 
or soundware developer as to how these impulse responses appear to the end-user within GVI.  

 

For instance, in the case of GigaPiano II, a piano soundboard resonance IR was embedded 
directly into the GIG instrument that the actual piano sample data is stored in. Because of this 
integration, the GigaPiano II appears as a single instrument when loaded into GVI; the 
illuminated “FX” button indicates that the instrument also contains embedded convolution.

Alternatively, a developer might choose to leave their GigaPulse content and Sample content 
separate, or modular. In these cases, the GigaPulse convolution appears as its own instrument 
on a Stacked Instrument Sub-Channel. This kind of Stack contains two types of instruments, 
those containing traditional sample data and those containing encoded GIG Instrument Banks 
(Impulse Responses). Again, the illuminated “FX” button indicates that the instrument sub-
channel contains embedded convolution.

OPENING THE GIGAPULSE UI 

There are two methods by which the GigaPulse UI can be opened from within the MIDI Mixer: 

 

 

 

   

FX Button:

 The FX button is located on the channel strip or sub-channel strip that 

contains the instrument with embedded convolution. Clicking on the green FX button 
will open a menu that lists all of the GigaPulse Instances and encoded GIG Instrument 
Banks available for that particular channel. From this FX menu, select “Edit” to open the 
GigaPulse UI (when only one bank is available, simply click on the bank name).  

 

  

 

GigaPulse Button:

 This global GigaPulse button is located in the GVI Navigation 

toolbar. The GigaPulse Button only becomes active when a channel containing an 
embedded GigaPulse instrument is selected.  Clicking on this button will then open the 
GigaPulse instance that exists on the selected channel.
