Quick Start-Loading & Adjusting GigaPulse

Load GigaPulse:

There are two ways to load gigapulse.

For GigaPulse VST, consult your DAW software documentation on how to use VST plugins. (Some host applications allow you to insert VST FX on a mixer channel strips) Once GigaPulse VST is up and running, it works nearly identical to GigaPulse Pro. (The

GigaStudio 3.0 built in version)

For GigaPulse Pro, assign an instrument to a MIDI channel.

Then route that channel to a pair of inputs on the DSP Station mixer.

Open the GigaPulse on an insert in that DSP channel.

See the chapter “GigaPulse Pro Signal Flow” for a more in depth explanation of the Gigastudio signal ﬂow and instrument loading.

Alternatively, you can load a Gig ﬁle that has been encoded with a GigaPulse Instrument Impulse Set. When you load such an instrument, GigaPulse will also be loaded. You may open the GigaPulse interface or select different GigaPulse environments (if available) by clicking the ‘FX’ dropdown on the instrument’s MidiMixer Channel.

Select Environment:

In Acoustic Space, select the desired environment from the Bank dropdown list.

The drop down menu labeled Bank will bring up a Directory/File list of different recording spaces that are available on the system. Select the environment you want from the list it gives. What shows up in this list is determined by the settings in the ConﬁgurationWindow. (GigaPulse File Menu/Conﬁguration)

Note that the checked items in the bank dropdown menus indicate the currently select bank. If there are more than one check on a given menu cascade, then a single bank is selected and can be found using each of the redundant search paths being display.

Enable Microphones:

To enable the other microphones, simply click on them with the mouse. Keep in mind that each extra microphone uses extra CPU resources.

Alternatively, you can use the ‘ON” buttons in the Microphone Fader section to enable and disable mics (see “Adjust Mic Levels”, below). For GigaPulseSP, this is the only way to control microphone use.

Select Stage Positions:

Point Source Method:

Click on any single stage position (square) with the mouse. All the enabled mics will reference that one point for all the room characteristics. This is best for a single instrument or very small group, and is very good for monaural sources. Try out several positions while playing audio through the GigaPulse to hear the results.

Multi-Placement Method:

Instead of referencing a single position on the stage, the Multi-Placement mode mic selection allows speciﬁc microphones to be assigned directly to speciﬁc stage positions. To do this, hold down the ctrl key and then click on a mic. Then select a stage position. Repeat for the other mic positions that you want to assign.

Multi-Placement Mode can be used for a variety of effects.

Stereo spread across the stage spanning from any position to another. This would be ideal for a string ensemble. It would effectively place an ensemble across the stage and preserve the stereo image. Assigning and ensemble with the point source method tends to decrease the stereo imaging. In fact, you can’t tell the difference between a mono and stereo sample with the point source method.

GigaPulse Pro Input Levels:

GigaPulse VST Input Levels:

There are separate controls for the Left, Right and Master input levels. The Master level will adjust the Left and Right levels together while keeping them relative to each other. Each slave control’s relative position is remembered even if the master attempts to drive the slave past a maximum or minimum point.

Moving the individual Left or Right inputs will also adjust the Master input level by 50 percent. If you move one of the Left or Right knobs, the Master will be increased or reduced by half that amount. (Showing the average between the two signals)

If the master is moves such that it forces one (but not both) of the faders to the maximum or minimum, the Master will maintain the average of the two faders trajectory (the position of the fader if it had NOT been limited by the maximum or minimum). As such, a maximized slave fader will not move until the master has pulled the slave’s trajectory below the maximum value.

For GigaPulse SP and Pro there are 4 mic groups, typically Front, Wide, Surround, and Center (although the impulse set designer may give these groups (and the mics within them) alternative names. GigaPulse VST only has one mic group and defaults to the front mic group of a given impulse set.

Note that each mic group has a Master and two slaves (only one slave and no master’s for the center mic group). The master/slave controls work in the same way as the input level controls. If a mic group is not displayed, it is because the mics within the group have no impulses or have been disabled by the impulse set designer.

For GigaPulse Pro, there is also a Master Mic Group which controls the masters of the 4 individual mic groups.

Acoustic Space: Cascade Button

The Cascade Button combines the beneﬁts, settings & impulse sets of two different banks while using the CPU resources of only one. You get two for the price of one using this feature. A room impulse uses plenty of CPU resources as it is. Imagine you also want to add a Violin Body or Piano Resonance to the mix. Normally doing so would require two separate instances of GigaPulse to be loaded and thus twice the CPU load. However, Cascade Mode resolves the problem by combining two or more impulse sets.

The only limitation with the Cascade feature is that you lose access to the settings of the ﬁrst GigaPulse banks once you have clicked on the cascade button. You can tweak the second one after cascading but not the ﬁrst one.

To use the cascade mode of GigaPulse to Combine two ImpulseSets:

For example, you can apply a ConcertHall as well as a PianoBody to a dry piano.

1. Select a Bank to load the ﬁrst ImpulseSet (i.e.ConcertHall) and adjust the controls to your liking.

2. Click on the ‘Cascade’ button to turn it on (the yellow ‘on’ light should appear in the ‘Cascade’ button).

3. Select a Bank to load the second ImpulseSet (i.e. PianoBody).

At this time, the latest impulse set that is loaded (i.e. PianoBody) is combined with the ﬁrst (ConcertHall) sound created in step (1). As you play notes, you will hear attributes of each…as if your instrument is being played in the (PianoBody) within the (ConcertHall).

Note that the ‘Cascade’ button’s ‘On’ light remains in the ‘On’ state. This indicates that GigaPulse remains in ‘Cascade Mode’ (cascading the ﬁrst impulse set (ConcertHall) with the current ImpulseSet and settings). If desired, you may encode this cascaded GigaPulse conﬁguration to a Gig File using the ‘File’ menu’s ‘Encode Current Cfg to a Gig Instrument’.

4. Repeat Step 3 as often as desired. For example: Load a different ImpulseSet (i.e. GuitarBody).

At this time, the latest impulse set that is loaded (i.e. GuitarBody) is combined with the ﬁrst (ConcertHall). As you play notes, you will hear attributes of each…as if your instrument is being played in the (GuitarBody) within the (ConcertHall). The (PianoBody) impulse set is no longer applied…it was replaced by the (GuitarBody).

GigaPulse™ User Guide

GigaPulse Interface

5. To disable ‘Cascade Mode’, simple click the ‘Cascade’ button again and the ‘On’ light will turn off. This indicates that ‘Cascade Mode’ has been disabled.

At this time, all preserved cascade states are removed. You will only hear your instrument’s notes being played through the current GigaPulse conﬁguration.

GigaPulse Interface

To use the cascade mode of GigaPulse to Combine more than two ImpulseSets:

For example, you might want to remove an OriginalPianoBody from a normal piano GigInstrument, then apply a ConcertHall as well as a ReplacementPianoBody.

1. Load the ﬁrst ImpulseSet Preset (i.e. ConcertHall).

2. Click on the ‘Cascade’ button to turn it on (the yellow ‘on’ light should appear in the ‘Cascade’ button).

3. Load the second ImpulseSet Preset (i.e. InverseOriginalPianoBody, to remove the piano body).

As before, the latest impulse set that is loaded (i.e. InverseOriginalPianoBody) is combined with the ﬁrst (ConcertHall). As you play notes,you will hear attributes of each…as if your instrument is being played without the (OriginalPianoBody) within the (ConcertHall).

You may continue to tweak the controls and change banks/presets. As long as the ‘Cascade’ button light remains on, your current GigaPulse conﬁguration is being cascaded with the GigaPulse conﬁguration preserved in steps (1) and (2).

4. To apply another cascaded impulse set, use the Super Cascade Mode. Hold down the control key and click on the ‘Cascade’ button (Ctrl-Cascade).

Note that the ‘Cascade’ button light goes off momentarily. When it comes back on, your current state (steps 1-4) is preserved as a combined model (ReplacementPianoBody+Co ncertHall). You are again in normal ‘Cascade’ mode, ready to bring in your third impulse set (ReplacementPianoBody).

GigaPulse™ User Guide

GigaPulse Interface

5. Load a third ImpulseSet (i.e. ReplacementPianoBody).

At this time, the latest impulse set that is loaded (i.e. ReplacementPianoBody) is combined with the preserved model (ReplacementPianoBody+ConcertHall). As you play notes, you will hear attributes of each…as if your instrument is being played with the (OriginalPianoBody) removed, the (ReplacementPianoBody) added, and within the (ConcertHall).

You may continue to tweak the controls and change banks/presets. As long as the

‘Cascade’ button light remains on, your current GigaPulse conﬁguration is being cascaded with the GigaPulse conﬁguration preserved in steps (1) thru (4).

If desired, you may encode this cascaded GigaPulse conﬁguration to a Gig File using the ‘File’ menu’s ‘Encode Current Cfg to a Gig Instrument’.

6. Repeat steps 4-5 as often as required for your needs.

7. Turn off ‘Cascade Mode’ by clicking on the ‘Cascade’ button.

At this time, all preserved cascade states are removed. You will only hear your instrument’s notes being played through the current GigaPulse conﬁguration.

PLACEMENT SELECTION:

Note: Not available in GigaPulse SP.

Having the performance and the performance space are only two parts of the recording equation; microphones are still required. Using Placement Selection, you can control the mics and their relationship to a variety of stage or environment positions

Halls & Room Environments:

For Halls & Rooms, the Placement Selection pane shows placement of the mics – round markers – and up to 18-labeled square stage or environment position markers.

The stage position markers show where the Impulse Responses were measured in the real world when the impulses were created. This will permit you to move different instruments around the stage, whether right or left, or closer or farther away.

Tail Model:

The user may override enable/disable of the tail extention (for impulses sets over 3

seconds in length) by clicking on this button. Note that when a new bank selection is made, the user override will be cancelled and the impulse set’s default will be set.

The Tail Model is used when dealing with impulses that are longer than 3 seconds. (48khz 131072 samples to be exact). After 3 seconds, the Tail Model will smoothly blend an algorithm reverb tail near the 3-second cutoff into the digital reverb. This can save a lot of CPU resources with virtually no noticeable change in audio. (This tail will ideally kick in at very low levels as the reverb is trailing off) If the impulse environment is less than 3 seconds, the Tail Model will not be enabled, and enabling it will have no effect.

MIC REPLACEMENT:

Different microphones have different recording characteristics. Microphones come

in different quality levels (price will be a clue), and they also have different directional characteristics (Omni directional, Cardoid, Wide Cardoid, Hyper Cardoid, Figure 8), They may also give different responses according to the pitch or timbre of the source audio. To cover all these possibilities, GigaPulse includes a generous selection of Microphone impulse models. You can use these to remove the characteristics of one microphone and replace it with the characteristics of another. Note: Processor impulses may also be used here. “E.G. Boxinator”

Note that using original (inverse) and/or replacement mics (as well as Pattern and Filter selections) will cause GigaPulse to run pause and run a short calculation when the mic models are chosen, but they do not require additional CPU when processing audio.

Drop Down Menus:

GigaPulse gives you a generous choice of microphones. Choose these using the Drop Down Menus.

Original Mic:

Provides a list of microphones that might have been used in

the original recording that is being processed by GigaPulse.

By selecting the appropriate mic, you apply the inverse

impulse response, which effectively removes its character of

the selected mic model from the original audio.

(This is why we have the (inv) at the beginning of the majority of choices.)

Replacement Mic:

Provides a similar list, but these microphones are used to

replace the original one.

GigaPulse™ User Guide

One thing is important to understand here, that the match with the microphones used may not be absolutely perfect. The characteristics employed by GigaPulse are those of good condition, unmodiﬁed models,and there may be variations according to age and wear. The match should be fairly close in most cases though.

TurboMode->PureMode (not recommended)

PureMode is a 100% mathematically perfect convolution without the use of an artiﬁcial reverb tail model for up to 3 seconds.

Convolution is very CPU intensive and therefore the default setting (Turbo Mode) is an effective limit of three seconds of actual convolution at 48 kHz before going into the Tail Model.

It is very likely that PureMode can be used more in the future, as computers get more powerful. Until then however, we recommend leaving it set to Turbo Mode. Pure Mode would mainly be used for ambiences that are longer than three seconds and the artiﬁcial tail model is noticeable.

Render Current Cfg to a single Source Placement

This feature is used to compress a multiple source impulse set down to a single source set. A single source impulse set deletes all the un-referenced impulse positions leaving a single position and the microphones. There are a couple of reasons why you would want to collapse and impulse set down like this.

The main purpose is if you want to encode an impulse to a .Gig ﬁle in GigaStudio

3.0. When an impulse is encoded to a gig ﬁle,it will automatically load when ever the instrument is loaded into GigaStudio with all its default settings. It doesn’t use up any inserts or aux busses in the process. This is often done for convenience and simpliﬁcation. Simply load the instrument and play without having to go load GigaPulse, hunt for a bank and make settings. Everything is ready to go as soon as the instrument is loaded. However, it also allows developers to ship built in impulse banks with their libraries and they will work on all the versions of GigaStudio 3.0. (GigaPulse Pro is not included in the lighter versions)

The other purpose would be to simplify favorite banks and have them use fewer resources. For example, an impulse set with 18 stage positions could be 33 megabytes. When reduced to a single source, it can get down to about a single megabyte in size. That saves RAM and hard disk space.

Start off by loading a room or a hall and making some placement and parameter settings. (Use the Multi Placement mode and assign at least two or more of the mics to their own stage position. )

In this example, we are using the

Empirical Room

bank that ships with the GigaPulse.

GigaPulse™ User Guide

GigaPulse File Menu

This impulse set is 66 megabytes in size on the hard drive at this point.

That is because it has all 18-stage positions for every microphone built into it. (up to 128 impulses) These are available and ready to access at a moments notice. However, by reducing this bank down to a single source, we can drastically simplify and reduce the

size of it.

Next, choose

To use this feature, you would ﬁrst pick out your bank and make all your settings. In this case we will use the Violin body.

The impulses of the Violin bodies are recorded from 6 positions. Experimenting with enabling & disabling various mics and adjusting their levels & perspectives can create an inﬁnite variety of sound characteristics.

Using all the mic positions at once uses a lot of extra CPU power.

If we have all 6 enabled at once, mixing them down will cut the CPU usage down to a third of the amount. (2-channel stereo instead of 6 channels)

Use the Mic to Mixer routing to assign the violin mics to the DSP station mixer channels. In this case, they are all going to 1-2.

You can tweak the individual mic levels & perspective and even replace the microphones with other models.

Once its done saving, we are left with a simpliﬁed version of the Violin impulse bank.

The graphic is the same but there is now only one violin body available and two mic positions. (these are the mix downs of the 6 earlier ones represented by the two overhead mics)

Mic to Mixer Routing has been pared down to the two channels.

The Mix Master section is also pared down to the two channels.

What we have at this point is the same audio result as before but it is mixed down and more manageable. It also uses a third of the CPU resources. The only thing that is lost at this point is the ability to choose violin bodies & mic positions & adjust the mic levels etc. You can always go back to the original bank and start over though. You can create a huge collection of your favorite bodies and mic settings using this technique.

GigaPulse™ User Guide

GigaPulse File Menu

Keep in mind the number of resultant mic channels is dependent on the DSP station routing. You could have GigaPulse Mic to Mixer setup to use all 7 output channels, but if the DSP station mixes these down to 2 hardware output channels, then you’ll only get 2 mic channels.

The DSP Station’s routing and fader and pan values are also taken into account when calculating the impulse set’s new impulses (insert, group, output). However, no other DSP Station feature is calculated into the resultant impulses (no EQ, Dynamics, other effects).

Encode Current Cfg to a Gig Instrument Preset: (GigaStudio 3 Orchestra & GigaPulse Pro Only)

This feature allows you to encode a currently loaded GigaPulse conﬁguration to a GigaStudio instrument. Doing so embeds the GigaPulse environment into the instrument. When the instrument is loaded into GigaStudio, the environment is also loaded with all the default settings. This has proven most useful for things like the GigaPiano II where the pedal down resonance is pure GigaPulse audio. Just load the piano and play it. The sustain pedal triggers the GigaPulse environment as you play it.

This could be done manually by loading just the piano samples to a MIDI channel and then opening GigaPulse on an insert in DSP station, then ﬁnding the Piano resonance bank. However, encoding the GigaPulse environment saves all that hassle.

Now the meters in channels 1-8 light up.

1,2 is the Front L & Front R Mics 3,4 is the Wide L & Wide R Mics 5,6 is the Surr L & Surr R Mics 7 is the Center Channel Mic (Left side)

You can even label the mixer channels as we have in this example.

At this point it is not recommended to assign any audio through channels 3-8 since they are occupied with audio routing.

Be sure to experiment with enabling & disabling various mics and test out various Mic to Mixer Routing settings and check the results in the mixer meters.

The last step in routing the audio is to assign the mixer channels to audio outputs.

At the bottom of each mixer channel is an

dropdown menu.

From that dropdown menu, you can assign the mixer channel to a mixer group or directly to the audio card outputs.

In this case, assign each channel to a different audio output.

Channel 1,2 to Outputs 1,2 Channel 3,4 to Outputs 3,4 Channel 5,6 to Outputs 5,6 Channel 7,8 to Outputs 7,8

Now the audio will be routed to the physical outputs of the sound card.

7-Channel Audio:

To get a full 7-channel surround environment in the studio you would need 7 speakers arranged similar to the mic positions to reproduce the GigaPulse Halls & Rooms. Other impulse banks in the future could have differing mic setups. The Wide mics could be in between the front and center mics for a wide screen array for example. (Like 7.1 theater cinema setups)

If we were connecting the GigaStudio audio card directly to the speakers, this is how

the audio outputs would get assigned.

Outputs 1,2 to the Front Left & Right Speakers Outputs 3,4 to the Wide Left & Right Speakers Outputs 5,6 to the Surround Left & Right Speakers Outputs 7 to the Center Speaker.

The same concept applies if you are using a mixer, rewire or an external sequencer. Eventually, these channels would be routed to these particular speakers.

5-Channel Audio

If you don’t have a full 7.1 channel system but instead have a 5.1 system, you could do a couple of things.

Disable the Wide Left & Right Mic positions and just not use them.

Or you could keep them enabled and assign them to the same channels as the Front Left & Right Mic channels.

This would then only use 5 channels instead of 7. Those can then be routed to 5 audio outputs.

2-Channel (Stereo) Audio

GigaPulse-Pro Signal Flow

If you are dealing with a stereo monitoring environment (only two speakers) then set the Mic to Mixer Routing to “True Stereo” This automatically collapses all the mic positions down to two channels.

GigaPulse Mic to Mixer routing-Aux Busses

Once you are familiar with how the routing works, you can then more easily move on to using the Auxiliary Sends & Returns. This allows several mixer channels to share a single instance of the GigaPulse or any other effect plug-in.

Expand Aux Channel one by clicking on the triangle. (Same as with the mixer channels)

In this case, go to the DSP Station and select the at the bottom. This will bring up the Aux Returns channels.

Aux Returns tab

GigaPulse-Pro Signal Flow

Click on the triangle on the top insert slot and open the GigaPulse. (Same as before on the mixer channels)

Now we have the ﬁrst 4 Aux Return channels

assigned to the hardware outputs.

Just like with the mixer channels, you can now assign the Aux Return channels to the audio card outputs.

The Mic to Mixer Routing will now spread the

GigaPulse audio across these channels the same

was as before with the mixer channels.

At this point it is not recommended to assign

anything to Aux Returns 2-4 since they are occupied

with audio routing.

Now go back to the channel inputs and enable Aux Send 1 and crank up the level to hear the result. You can do this with any mixer input channel and several channels can now use the GigaPulse at the same time with custom amounts of effect on each channel.

The GigaPulse audio will be routed to the audio channels.

Mic to Mixer Routing-Different channels

Ok, what if we put the GigaPulse on some other pair of channels. (11,12 for example) What would the Mic to Mixer Routing display then?

This is very straightforward. The numbers would start at 11 and go through 17 instead of 1-7.

100

Everything still works the same but using channels 11-17 instead.

Keep in mind that in this setup, we don’t recommend assigning any instruments to channels 13-18.

They are being used to route the GigaPulse audio and any instrument assigned to them will also get routed to the channels output and it will interfere with the GigaPulse audio path.
