Normally, all groove patterns start at Bar 1 and repeat themselves throughout a song. For example, a 4-bar groove pattern will begin at Bar 1 and repeat its pattern every four bars. Many times, however, songs begin with blank measures, pickup measure or, perhaps, a short introduction. In these cases, you probably don't want the groove pattern to begin at Bar 1, but at some later bar. This is the purpose of the anchor point - it tells Reason Essentials at which measure it should begin applying the groove settings.
For example, assume you have a song with a 1-bar pickup. Because the song really begins on bar 2, that's where you want your groove to begin. Setting the anchor point to 2 insures that the groove patterns all begin at measure 2.
This knob adjusts Reason Essentials's global shuffle amount, and is used by any devices that employ patterns, such as Redrum's internal sequencer and the Matrix pattern sequencer. It also defines the shuffle value for any ReGroove channel for which the Global Shuffle option is activated.
Setting the Global Shuffle to a value of 50% results in a “straight” beat, with no swing applied. Setting the Global Shuffle to a value of 66% results in a perfect sixteenth-note triplet shuffle. Values between 50% and 66% have a less pronounced swing feel, and values greater than 66% are more exaggerated.
This is an On/Bypass button for the channel. When the button is lit, the groove channel is active and any note lane assigned to this groove channel will be affected. When the button is not lit, the channel is disabled and any note lanes assigned to this groove channel will play back straight, without being “grooved.”
This is a non-editable channel number label. Channels are numbered 1-8 and are grouped into 4 banks (A-D). Channel numbers are named accordingly. For example, A2 is the second channel in Bank A, and B5 is the fifth channel in Bank B.
This shows the name of the groove patch currently loaded into the channel. If no groove patch is loaded, then no name appears. Click this area to bring up a list of the patches in the current folder, just as with patch displays on devices in the Reason Essentials rack.
Use this knob to slide notes forward or backward in time. Musicians will frequently add energy and urgency to a track by “rushing” a particular beat or instrument a little. Similarly, they may “drag” a note a little in order to create a more laid back, shuffle-like feel. The Slide knob has a range of ±120 ticks, which allows you to slide notes up to a thirty-second note in either direction. Setting negative values makes notes play earlier in time (rushing the feel). Setting positive values makes notes play later in time (lagging the feel).
For example, if you wanted to create a slightly “in the pocket” groove, you could create a snare lane and assign it to a ReGroove channel with a small amount of positive slide. This would delay the snare track slightly, giving your music a relaxed, laid back feel.
Use this fader to adjust how intensely the selected groove patch will modify your notes. At 0%, the groove patch will have no effect. At 100%, the groove patch will have its maximum effect. Obviously, values between these extremes will produce some amount of groove effect, but less than maximum.
As discussed in “Groove Settings”, later in this chapter, several additional parameters are associated with groove patches and how they modify your notes. Specifically, the Groove Settings section of the Tool Window contains four “impact” settings (timing, velocity, note length, and randomness), and the Groove Amount fader acts like a “master” fader that scales these four parameters proportionally.
Enabling this button causes any incoming notes to be quantized to a rigid, sixteenth note grid prior to having any additional groove modifications applied to them. This quantization, which occurs in real time and is non-destructive, is an easy way to align all incoming notes to a “straight” grid, so that any shuffle, slide, or groove modifications have the expected effect on the notes.
Enabling this button causes the ReGroove channel to use the “Global Shuffle” setting, rather than the channel's own shuffle setting. The channel's Shuffle knob will have no effect when a channel uses global shuffle. Using global shuffle is a good way to synchronize notes in a particular channel with those in pattern-based devices, such as Redrum’s internal sequencer and the Matrix pattern sequencer, all of which get their shuffle values from the Global Shuffle value.
