The Lowender's controls will be explained in order of the signal flow from input to output:
The Range control allows you to select from three frequency ranges of subharmonic synthesis: Classic, Guitar, and Bass. The "Classic" frequency range is the range used by traditional subharmonic synthesizer hardware boxes (24-56 Hz, split into two bands at 36Hz). The Guitar and Bass settings target the lowest octaves of guitar and bass respectively. *
The knobs each control the level of one band of the synthesized bass signal.
The green LED in the top right lights when the gate opens; the red LED indicates that the gate is closed.
Can you guess what these do? The blender slider has three preset buttons right above it for 0%, 50%, and 100% blends. The output slider has a 0dB preset button, but careful not to clip the output!
The Lowender features mini LED meters (right above the Bass Synthesis level knobs) to show bass synthesis activity in the two frequency ranges. In the signal chain, these meters come right after the synthesis knobs, but before the gate or drive.
At the top of the plug-in window, switchable Input/Output metering is also provided. Watching the Output meter can help when setting the Master Output slider, to prevent clipping.
Please note that the signals generated by the Lowender range from roughly 20 - 60 Hz. This means that you won't hear the subharmonic content if you're monitoring on smaller speakers. Please be sure to try out the Lowender using appropriate monitoring! Even a good pair of headphones can provide better extended bass range than typical nearfield monitors.
* With the Classic setting, the bass synthesis affects only up to around a low A on guitar. With the Guitar setting, the synthesis affects roughly up to the low D# (fourth string, first fret) on standard guitar tuning (and likewise, the low D# on bass for the Bass setting).
