When you set a manual step rate, the LFO rate can be changed without altering the number of steps. The slider smooths the normally steep slopes of the square and random waveforms. The LFO rate can be modulated by the envelope. To pop-up menu: Choose a continuous controller number, aftertouch, or pitch bend as the LFO output target.
You can also learn a plug-in parameter. Offset slider: Set a positive or negative offset in order to tailor the output for the intended target. Choose a MIDI output channel. Waveform display: Shows the LFO waveform shape.
This deforms the waveform in the following ways: Triangle: Shapes the triangle waveform into either an upward-sawtooth or downward-sawtooth waveform. Both the envelope and LFO sections have their own amplitude and offset adjustment so that you can determine the range over which the target parameter is controlled. An oscilloscope—type display at the bottom of each section shows the shape of the modulation signal. The outputs from the LFO and Envelope sections can be sent to MIDI CC numbers and traditional parameters such as pitch-bend and aftertouch or, using the 'Learn Plug-in Parameter' option, to any parameter of any plug-in inserted after it.
However, if you select 'Learn Plug-in Parameter' from the 'To' pop-up menu in either section, you can target any control in any plug-in sitting below it in the channel strip, just by adjusting the knob or slider you want to control.
The name of the plug-in and the target parameter is then shown in the 'To' display. The process is the same for the LFO and Envelope sides of the plug-in, and either can be turned off if not required using the orange radio button in the top left—hand corner of the section. A word of caution here: not all plug—ins are designed to allow all their parameters to be adjusted smoothly. For example, if you target the Delay or Level parameters of Logic's Phase Distortion plug-in, there are audible clicks and glitches, though its Intensity control works quite smoothly.
If you're wondering what you might use this plug-in for, I can offer a few suggestions, the most subtle of which is to add small pitch or amplitude changes to instruments to make them sound a touch more human — or more analogue.
This works particularly well with sampled drums. You can also use a combination of LFO and envelope to add minor changes to the envelope of the original sound, again to add a touch of organic variation.
Though you can't target the channel fader or aux sends, you can target any plug-in that allows smooth control over its output level if you need to modulate the overall amplitude. This combination gets to be a lot more fun when you target the ESM synth's pitch-bend using Modulator's Envelope output to add a slight pitch dive at the end of each note, while feeding the LFO side to Phase Distortion's Intensity control.
Suddenly a rather dull old TB wannabe becomes a bass instrument capable of serious attitude. Other avenues of exploration that have yielded useful results include using both the LFO and Envelope sections to target the filter cutoff frequency of a synth — and that can produce quite complex-sounding results when you set the envelope also to modulate the LFO level.
There aren't many presets to play with as the designers don't know what plug-ins you plan to use, so the ones that are included are pretty generic, affecting pitch and level. The value is shown in note values when the Sync button is active. Fade field: Use to set the time it takes for LFO modulation to fade in or fade out, depending on which Fade button is active.
Use the Fade field to set the fade duration. Waveform display: Shows the current LFO waveform. Drag horizontally to set the frequency, or speed, of LFO modulation. Mono results in identical modulation of all voices. Poly provides independent modulation of each voice. Unipolar or Bipolar button: Run the LFO waveform in one pole positive or two pole positive and negative mode. Each time you play a key, the LFO waveform is restarted from the start point.
