How to create two Gig Performer instances with a single client ASIO Driver on Windows

How to create two Gig Performer instances with a single client ASIO Driver on Windows

Gig Performer has built-in support for multiple instances. Creating a second Gig Performer instance is easy. Just select File -> Create New Instance… (or open an existing one) and you’re all set:

Two instances of Gig Performer - guitar and keyboards

This works great on macOS and on many Windows computers without further tweaking.

Unfortunately, some Windows ASIO drivers still allow only one application (Gig Performer with two instances counts as two applications) to use the audio interface at a time. These are known as single-client drivers. Multi-client audio drivers started coming out years ago, but sadly there are still many drivers out there that do not allow you to use the same audio device with more than one audio application at a time. This also prevents your second Gig Performer instance from using the audio interface.

If you find yourself in this situation, the first thing you should do is to see if there is an update for your audio device driver available that does in fact support multiple applications simultaneously. Consider also complaining to the company providing the driver, if they hear from enough people, perhaps they’ll fix it.

If there is no update, there’s still a way — just follow these instructions:

  1. Install the ASIO4ALL drivers on your computer
  2. Open (or create) a second Gig Performer instance and go to its Audio Options,
  3. Select the ASIO and ASIO4ALL driver matching the sample rate of your main instance.
  4. Click on the “Control Panel” button once you have switched to the ASIO4ALL driver and make sure that your real audio interface is selected within the ASIO4ALL driver.

That’s it. Your second instance will remember the specified audio settings and will now always open using the correct driver.

Should you need to route MIDI from one Gig Performer instance to another – you can use install a virtual MIDI port driver (NB, if you happen to be reading this but are using a Mac, virtual MIDI ports are built-in to OS X and are called IAC ports).

LoopBe1 is a free MIDI loopback driver for personal use. You can download it here: 

There is also loopMIDI from Tobias Erichsen

Once installed and configured if necessary, virtual MIDI ports simply show up in Gig Performer as another input or output MIDI device. Just send any MIDI data you want from one Gig Performer instance into a MIDI Out block for LoopBe1 and receive it in your other instance using a MIDI In block.

One caveat: make sure you are not using any MIDI In OMNI blocks if you’re doing this. Otherwise you will set up an infinite feedback loop because MIDI In OMNI blocks will receive all incoming MIDI data, including data you just sent out.

Scaling Curves

Scaling curves allow you to control the shape of the output of a widget or convert an incoming note velocity to a new velocity. Various predefined curves are available and they can be tweaked as necessary. You can also just draw your own curve as well to achieve the effect you require.


MIDI File Player Plugin

You can load up to 128 MIDI song files in a single plugin instance. Switch from one song to another, mute tracks and/or change their channel numbers. Tempo can be controlled by individual songs or you can use the global tempo and tap tempo to control the BPM interactively.


Favorites and Presets

Create a sound by placing and interconnecting your desired plugins, such as a synth, some effects and perhaps a mixer. Select them all and then save the selection as a named favorite. The favorite will subsequently show up in all plugin insert menus, making it easy for you to recreate that configuration whenever you need it again. This feature is also very powerful for creating your needed sounds on your studio computer and then transferring them to your touring laptop.


Probabilistic Sound Designer

Parameters you select in an open plugin are captured into the Probabilistic Sound Designer dialog window. When you click Randomize, you're only adjusting those selected parameters. Each entry in the PSD dialog has a curve but unlike widgets where the curve controls scaling, in the PSD the curves are used to define the probability of particular values being selected. Make sure the filter cutoff never gets too slow so as to block all sound. Perhaps adjust the max range of the VCA attack parameter so that the sound doesn't have too much delay. Constrain the octave ranges of the oscillators, perhaps ensuring that 1/3rd of the time we select 8' and 2/3rds of the time we select 4'. The possibilities are endless.


More Widgets

Numerous new widgets are included in Gig Performer - a new sustain pedal, plastic knobs, drum pads and more colored sliders. Shapes can be colored with different borders and fill colors and morphed from rectangular to circular. Your creativity is now the limit to creating fabulous front panels in Gig Performer.


MIDI Message Helper

Select MIDI devices by name. Choose the MIDI message type and adjust the appropriate parameters for the specific type



Layout management

Gig Performer supports arbitrary resizing. Layout your widgets the way you want - resize the main window and the widgets will grow or shrink as necessary to maintain the same interrelationships. No matter what size screen you have, your front panels will still be neat and usable.


Undo Support

If you move your widgets around and/or resize them, or even delete them by mistake, the Undo facility will correct your mistake. Minor moves to a widget by mistake will no longer spoil your design


Plugin Channel Count

Some plugins support a large number of outputs and they depend on the traditional channel strip to control how many ports should be available.   When you only need a stereo pair, it is convenient not to have a large horizontal block. In Gig Performer, the number of available ports  is controlled by the channel count override, which can be applied to individual plugins and will be remembered when the gigfile is reloaded or if the plugin is saved as a favorite.


Input muting and output fading

Rather than a single audio length tail, Gig Performer 4 gives you the ability to control input muting and output fading separately. Input muting controls how much time it takes for audio input to be silenced when you leave the rackspace. Output fading controls how much time will be taken for audio to fade out when you leave the rackspace.


Faster Plugin Finder

Instead of searching through menus of perhaps hundreds of plugins (you know who you are!), the Quick Plugin Finder makes it easy to find the plugin you need by simply typing partial strings. For example, as shown here, to find the Modartt Pianoteq 7 plugins, it's enough to type pia mod 7 (in any order, by the way)  to restrict the list of available plugins to those matching your query. The Quick Plugin Finder also knows about manufacturers, presets and favorites.



Touch Friendly Input

Any entry field can be changed by either dragging your mouse (or finger) up or down, or by using the large popup touchpad where you can just tap on the squares to enter a value. The large popup keypad also does validation so you can't enter an invalid value. You can also just tap the BPM field to pop up a larger view where you can quickly change tempo, tranpose, trigger Tap Tempo and enable Ableton Link, the last allowing you to synchronize Gig Performer with any other application that also supports Ableton Link.


New Tuner Display

The tuner view makes it easy for guitarists to quickly check and adjust their tuning. You can toggle into the tuner view from any other view and toggle right back as soon as you're done. All output will be silenced automatically while you're in tuning mode. You can adjust the concert reference pitch from its default of 440 Hz to suit your own needs. The tuner view fills the entire screen so you can easily see it from a distance.
