Bass Amp Designer amplifier controls in Logic Pro for iPad
The amp parameters include controls for channel selection, input filter and gain, and master output. The Gain knob is located in the Amp section, the Master knob is in the Amp Out section, and the Output Gain slider is found in the Output section.
Amplifier parameters
Amp pop-up menu: Choose an amplifier model.
Channel pop-up menu: Choose channel I or channel II.
Channel I is active, with a gain of 0 dB.
Channel II is passive, with a gain of -15 dB.
Bright button: Tap to switch between normal and bright modes. When bright is active, highs and upper mids are added to the tone.
Note: The increased mid and high range may lead to a perceived low end roll-off. Use the Bass EQ knob if you feel the bottom end needs a boost.
Gain knob and field: Set the amount of preamplification applied to the input signal. The Gain knob affects amp models differently.Master knob and field: Set the output volume of the amplifier signal sent to the cabinet. Increasing the Master level typically produces a compressed and saturated sound, resulting in a more distorted and louder signal.
Note: If you choose Direct (PowerAmp Out) from the Speaker pop-up menu, the output signal is routed directly to the Amp/DI Mix knob. However, if you choose Direct (PreAmp Out) from the Speaker pop-up menu, the Master knob acts as a pre-amp master gain control before the output signal is routed to the Amp/DI Mix knob.
- Output Gain control and field: Set the final output level of Bass Amp Designer.
