Astra Settings

With UAFX Control, you can configure how Astra behaves when bypassed, and what the right footswitch does.

Configuring Bypass Routing

Astra Modulation Machine effect bypass routing can be set for true bypass or buffered bypass. Bypass routing determines how the pedal behaves when the effect is off.

For additional details about why you might want to use these routing modes, see this article

 

True Bypass

 

astra-tbp-preset.PNG

 

When bypass routing is set for true bypass and the effect is off, the dry signal is pure analog dry-through from input to output, without buffering or any other circuitry, via mechanical relays. By default, your UAFX pedal is set for true bypass. 

When set for true bypass and the effect is on, the output is buffered.

To set Astra for true bypass

Under Bypass Routing, tap True Bypass. 

 

Buffered Bypass

 

astra-bbp-preset.PNG

 

When bypass routing is set for buffered bypass, the output is buffered when the effect is on, and also when the effect is off. 

When the effect is off, the dry signal remains analog dry-through.

To set Astra for buffered bypass

Under Bypass Routing, tap Buffered Bypass. 

 

Configuring the Right Footswitch

The behaviors of the right footswitch can be changed to suit your preferences. Note that the left footswitch always toggles Live mode, where the knobs and switches are “what you see is what you hear” (except the speed knob, if tempo is tapped).

Astra’s right footswitch has two available settings:

Preset*

Live mode and Preset mode are available. Tap tempo is unavailable.

Preset + Tap

Live mode, Preset mode, and Tap Tempo for both modes are available.

*Default setting from factory and after restoring defaults

 

Preset

footswitch-state-preset-border.png

When set to Preset, the right footswitch immediately loads the preset with its stored tempo, and toggles the preset on/off. Tap tempo is unavailable with this setting.

To set Astra’s right footswitch for Preset mode

Under Right Footswitch, tap Preset. 

 


astra-preset.png

 

Preset + Tap

When set to Preset + Tap, the right footswitch performs multiple functions.

Load Preset: Hold the right footswitch for 1.5 seconds (or longer) to load the preset with its stored tempo when the footswitch is released. The Effect Type LED blinks rapidly when the preset is armed for loading. 

Bypass Preset: Hold the right footswitch for 1.5 seconds (or longer) to bypass the preset when the footswitch is released. The Effect Type LED blinks rapidly when the preset is armed for bypass. Tip: Tap the left footswitch twice to quickly bypass the pedal from Preset mode.

Tap Live/Preset Tempos: Short-press (don’t hold) the right footswitch twice or more to tap quarter note tempo. In Live mode, the right footswitch LED blinks red at the current tempo. In Preset mode, the right footswitch LED blinks green at the current tempo.

To set Astra’s right footswitch for Preset+Tap mode

Under Right Footswitch, tap Preset+Tap.

Golden Settings

With UAFX Control, you can configure how Golden behaves when bypassed.

Configuring Bypass Routing

Golden Reverberator effect bypass routing can be set for true or trails bypass. Bypass routing determines how the pedal behaves when the effect is off.

For additional details about why you might want to use these routing modes, see this article.

 

True Bypass

When bypass routing is set for true bypass and the effect is off, the dry signal is pure analog dry-through from input to output, without buffering or any other circuitry, via mechanical relays. By default, your UAFX pedal is set for true bypass.

When bypass routing is set for true bypass and the effect is on, the dry signal remains analog dry-through and the output is buffered.

To set Golden for true bypass

Under Bypass Routing, tap True Bypass. 

 

 

golden-tbp.PNG

 

Trails Bypass

When bypass routing is set for trails bypass and the effect is off, the effect plays out naturally, rather than stopping suddenly. 

The dry signal remains analog dry-through when the effect is on and off, and the output is always buffered.

To set Golden for Trails bypass

Under Bypass Routing, tap Trails Bypass.

Starlight Settings

With UAFX Control, you can configure how Starlight behaves when bypassed, what the right footswitch does, and preamp coloration on the dry signal.

Configuring Bypass Routing

Starlight Echo Station effect bypass routing can be set for true or trails bypass. Bypass routing determines how the pedal behaves when the effect is off.

For additional details about why you might want to use these routing modes, see this article.

 

True Bypass

When bypass routing is set for true bypass and the effect is off, the dry signal is pure analog dry-through from input to output, without buffering or any other circuitry, via mechanical relays. By default, your UAFX pedal is set for true bypass. 

When set for true bypass and the effect is on, the dry signal remains analog dry-through (except when preamp coloration is enabled) and the output is buffered.

To set Starlight for true bypass

Under Bypass Routing, tap True Bypass. 

 

 

starlight-tbp.png

 

Trails Bypass

When bypass routing is set for trails bypass and the effect is off, delays play out naturally, rather than stopping suddenly. 

The dry signal remains analog dry-through when the effect is on and off (except when preamp coloration is enabled), and the output is always buffered.

To set Starlight for trails bypass

Under Bypass Routing, tap Trails Bypass. 

 

 

starlight-bbp.png

 

Preamp Coloration

Starlight Echo Station includes the preamp tone of the Tape EP-III and Analog DMM on the wet signal. The meticulously modeled preamps in these effects are renowned for their smoothness, warmth, and musicality. Preamp coloration can also be enabled on the dry signal with these effects. 

Preamp coloration behavior depends on the bypass routing setting. Preamp coloration is unavailable with the Precision and Cooper Time Cube effects.

To turn preamp coloration on or off

Under Preamp Coloration, tap Off or On to enable or disable preamp coloration on the dry signal.

 

starlight-color-off.png

 

Preamp Coloration Off

 

starlight-tbp-color-off.PNG

 

When preamp coloration is off, the dry signal is always uncolored and analog dry-through when the delay effect is on, and also when the delay effect is off, with both true bypass and trails bypass routings.

 

Preamp Coloration On (True Bypass)

 

starlight-tbp-color-on.PNG

 

When preamp coloration is on and bypass routing is set for true bypass, the dry signal is preamp colored when the delay effect is on, but uncolored analog dry-through when the delay effect is off.

 

Preamp Coloration On (Trails Bypass)

 

starlight-bbp-color-on.PNG

 

When preamp coloration is on and bypass routing is set for trails bypass, the dry signal is preamp colored when the delay effect is on, and also when the delay effect is off.

Preamp Coloration Notes

  • If the pedal is set for preamp coloration with trails bypass, the preamp coloration of the Live mode effect is heard when the effect is bypassed. 
  • If the pedal is set for preamp coloration with trails bypass, there are no delay trails with the Analog DMM effect. This matches the behavior of the original hardware, which does not have trails when bypassed.  

 

Configuring the Right Footswitch

The behaviors of the right footswitch can be changed to suit your preferences. Note that the left footswitch always toggles Live mode, where the knobs and switches are “what you see is what you hear” (except the delay time knob, if tempo is tapped).

Starlight’s right footswitch has three available settings:

Preset + Tap*

Live mode, Preset mode, and Tap Tempo for both modes are available.

Preset

Live mode and Preset mode are available. Tap tempo is unavailable.

Tap Tempo

Live mode and Tap Tempo are available. The preset is unavailable.

*Default setting from factory and after restoring defaults

 

Preset + Tap

 

starlight-preset-tap.PNG

 

When set to Preset + Tap, the right footswitch performs multiple functions.

Load Preset: Hold the right footswitch for 1.5 seconds (or longer) to load the preset with its stored tempo when the footswitch is released. The Effect Type LED blinks rapidly when the preset is armed for loading. 

Bypass Preset: Hold the right footswitch for 1.5 seconds (or longer) to bypass the preset when the footswitch is released. The Effect Type LED blinks rapidly when the preset is armed for bypass. Tip: Tap the left footswitch twice to quickly bypass the pedal from Preset mode.

Tap Live/Preset Tempos: Short-press (don’t hold) the right footswitch twice or more to tap quarter note tempo. In Live mode, the right footswitch LED blinks red at the current tempo. In Preset mode, the right footswitch LED blinks green at the current tempo.

Tap Tempo

 

starlight-tap.PNG

 

When set to tap tempo, the right footswitch taps quarter note tempo for Live mode only. The right footswitch LED blinks red at the current tempo. Although you cannot access the stored preset in this mode, its settings remain intact.

 

Preset

 

starlight-preset.PNG

 

When set to preset, the right footswitch immediately loads the preset with its stored tempo, and toggles the preset on/off. Tap tempo is unavailable with this setting.
