Adding a Beat Track

Back to: HLS Getting Started Manual

Let’s add a beat track. We will also illustrate another feature that can be used in HLS. Remember that we put our actual outputs in Universe 1. Our beat tracks do not have to be real output channels. We will add some outputs in Universe o to use for beat tracks and for other things.
Choose Manage Channels from the top tab and then Manage Raw Channels. For this example we will add 8 channels in Universe 0 (see Figure 1-37)..

First right next to the Number to Add/Replace Value entry enter 8.

Figure 1-37.

Next, change the Universe # entry. 0 was entered for the Universe #. Next, the starting channel entry was changed to 25 (remember that the Renard outputs will be using 1-24).
Once these three changes have been made, click on the Add button to actually add the new channels. You have now added 8 channels in Universe 0, starting at channel 25 (see Figure 1-38).

Figure 1-38.

If you scroll down to see the 8 new channels that were added for universe 0 you will see what is shown in Figure 1-39.

Figure 1-39.

Next the names of the 8 channels were changed and colors were changed for each channel (see Figure 1-40). The first three were named Beat_Track_1, 2, and 3. Then the next three were named Low or hi pass filter beat tracks. Note that there are high and low pass filter tools available under the WAV File tab at the top of HLS. You can set parameters for low or hi pass filters, and then use the O-scope display and create beat tracks also. Channels 7 and 8 were named Any_Use showing that channels can be used for anything you want. You may want to build effects on extra channels and then copy them to your actual outputs, for example.

Figure 1-40.

If you are still in the Simulator screen you will need to switch back to the Channel View screen. Choose the Manage Channels tab and then select Restore Channel View from Sequence Paint and the sequence editor should appear. Note that we can also go to the Sequence Paint screen from the Manage Channels tab.

Next we will create a group that includes our two trees and a beat track channel. Choose the Manage Channels tab at the top and then the Select Channels and Assign to Group selection. The screen shown in Figure 1-41 will appear. Click on the Check boxes under the Work column for every channel to be included in this group. In this example 1-6 and 25 were checked. These represent the 6 output channels for our two trees and the one for a beat channel. Six are real outputs and the beat channel is in universe 0 so it is not an actual output. Then a name (Both_Trees_And_Beat_Track_1) was entered for the new group name and the Save Changes button was clicked. Now we have created a group that includes 2 trees and the beat track and named it Both_Trees_And_Beat_Track_1.

Figure 1-41.

Next we will add the actual beat track. To add a beat track, put a check mark in the Beat Track Active check box on the top left of HLS (see Figure 1-42). Next you must specify a channel for the beat track. When we created the group named Both_Trees_And_Beat_Track_1, we added an extra output channel (number 25). We will use channel 25 (Beat_Track_1) for the beat track.

Figure 1-42.

Select the Manage Channels tab and then the Select a Beat Track Channel choice. In Figure 1-43 the channel named Beat_Track_1 was chosen to be the beat track.

Figure 1-43.

Select the channel you want to be used for the beat track and then choose OK.

Next you must turn the Preview Sequence check box off (upper tight in Figure 1-44), if it is on (upper right of HLS). Note the Beat Active Check box has been checked.

Figure 1-44.

Now we are ready to create a beat track. Hit the Play button (upper left on HLS) and then tap either the CTRL key or the left mouse button to create the beats. The beats will be shown as two filled cells for each beat (see Figure 1-45).
