Tascam US-428 and US-224: Assignment Overview

The following sections outline the assignment of Tascam US-428 and US-224 interface elements to Logic functions.

Note: The US-224 only offers four channel strips and transport controls, and lacks the EQ and Master sections (excluding the NULL button and data wheel) of the US-428. Many operations listed below are specific to the additional controls of the US-428, and cannot be performed with the US-224.

Tascam US-428 and US-224: Channel Strips

The following table outlines the channel strip controls and their assignments:

Note: A modifier button (such as NULL) shown below a control description indicates that the control has an alternate function or use while the modifier is held down.

Control	Modifier	Assignment
MUTE 1 to 8		SOLO LED off: switches Mute on/off; LED displays Mute status. SOLO LED on: switches Solo on/off; LED displays Solo status.
REC 1 to 8 LEDs		Displays Record Enable status.
	NULL	On if fader is higher than actual channel volume (in Logic Pro).
SELECT 1 to 8 LEDs		Displays select status (of channel).
	NULL	On if fader is lower than actual channel volume (in Logic Pro).
SELECT 1 to 8 buttons		Selects channel.
	REC	Activates/deactivates Record Enable status.
Fader 1 to 8		Controls channel volume.
	NULL	Allows you to update the fader position to match the actual volume (in Logic Pro).
Master fader		Controls Master volume fader (or Output 1 and 2, if no Master fader channel exists in the project).

Tascam US-428 and US-224: EQ Section

The following table outlines the EQ controls and their assignments:

Note: A modifier button (such as NULL) shown below a control description indicates that the control has an alternate function or use while the modifier is held down.

Control	Modifier	Assignment
Gain		Controls the Gain of the currently selected EQ band (of chosen channel).
Freq		Controls the Frequency of the currently selected EQ band (of chosen channel).
Q		Controls the Q Factor of the currently selected EQ band (of chosen channel).
HIGH		Selects EQ band 3 (allowing use of Gain, Freq, and Q controls for this band).
	ASGN	Switches EQ band 3 bypass state.
HI-MID		Selects EQ band 4 (allowing use of Gain, Freq, and Q controls for this band).
	ASGN	Switches EQ band 4 bypass state.
LO-MID		Selects EQ band 5 (allowing use of Gain, Freq, and Q controls for this band).
	ASGN	Switches EQ band 5 bypass state.
LOW		Selects EQ band 6 (allowing use of Gain, Freq, and Q controls for this band).
	ASGN	Switches EQ band 6 bypass state.

Tascam US-428 and US-224: Master Section Controls

The following table outlines the master section controls and their assignments:

Note: A modifier button (such as NULL) shown below a control description indicates that the control has an alternate function or use while the modifier is held down.

Control	Modifier	Assignment
AUX 1		Switches data wheel between Transport/Scrub mode and Send 1 Level.
	ASGN	Switches Send 1 Mute state.
AUX 2		Switches data wheel between Transport/Scrub mode and Send 2 Level.
	ASGN	Switches Send 2 Mute state.
AUX 3		Switches data wheel between Transport/Scrub mode and Send 3 Level.
	ASGN	Switches Send 3 Mute state.
AUX 4		Switches data wheel between Transport/Scrub mode and Send 4 Level.
	ASGN	Switches Send 4 Mute state.
ASGN		Modifier for function of EQ controls, AUX 1 to 4 buttons, PAN knob, and data wheel.
F1		Enables/disables Cycle mode.
F2		Enables/disables Autopunch mode.
F3		Enables/disables Scrub mode.
PAN		Controls panning of selected channel.
	ASGN	Sets currently selected channel’s input.
NULL		Modifier for NULL mode. NULL mode allows you to update the fader positions to match the actual volume (shown in Logic Pro).
Data wheel		AUX 1 LED on: controls the Send 1 Level of the selected channel. AUX 2 LED on: controls the Send 2 Level of the selected channel. AUX 3 LED on: controls the Send 3 Level of the selected channel. AUX 4 LED on: controls the Send 4 Level of the selected channel. F3 LED on: data wheel is in Scrub mode. None of the above is lit: data wheel is in Transport mode, and moves the playhead in one-bar increments.
	ASGN	Sets currently selected channel’s output.
