Using the Arrangement Editor for Live Triggering of Sequences

How can I use the Arrange Editor to trigger MIDI sequences from the K2 keys?


Each step in an Arrangement can be triggered by playing a key or keys on the keyboard. This can be great for live performance in which you want to loop sequenced sections and be able to control how long each section will last while you are performing.

  1. Create an Arrangement Song, following the basic steps outlined in the online tutorial "Using the Arrangement Editor to Assemble a Song"

  2. Go to the COMMON page in the Song Editor. There are two parameters on this page for use with key triggering of steps:

    Trigger Chan: This is the channel in which a key can be used to trigger an arrangement step. All notes from other channels will not trigger the steps. So you want to make sure this is the channel you are sending on from your keyboard.

    Trigger Ctl: This parameter allows you to choose a controller to determine if the keys will trigger the steps. If it is set to On, then when you send the appropriate note on the Trigger Channel, the step will start playing. But if you set it to a MIDI controller number assigned to a mod wheel, pedal, or slider, then the keys will only trigger the step when the controller has been turned on (in the case of a continuous controller, this would be anything above halfway).

  3. Now go to the ARRANGE page and select step 1. On the bottom line of the display you will see a series of parameters, used for triggering the step. As you will notice, there are both Low Key and High Key parameters. If you set them to the same note, then only that note will trigger the step. But if the High Key is set to a different key from the Low key, then you can actually trigger the step, transposed to different keys, by striking the various keys. The Low key will play back the step without any transposition (unless you have selected a transpose amount with the Xpose parameter). As you play up the keyboard chromatically, the song will be transposed in half step increments. As with the Xpose parameter, any tracks designated as Drum Tracks on the COMMON page in the actual songs used as steps (not in the Arrangement song) will not be transposed.

    Press the SetRng soft button. The display will ask you to strike a key for the low key and again for the high key. This method is usually faster than setting the individual parameter is the display. Choose a range of notes for step 1 and try playing them on your keyboard. (Make sure you are sending on the Trigger Channel, and that Trigger Control is On.) Notice that as soon as you strike the key, the step starts again. Only one step and one transposition can be playing at a time, and striking the key immediately starts the step (more on this below).

  4. Now lets take a look at the other two parameters:

    Latch: If this is Off, as soon as you let go of the key, the sequence stops. If you turn it On, then you can let go of the key and the step will play to its end, unless you press Stop, or retrigger a step.

    VelTrk: If this parameter is Off, then the sequence will play back exactly as it was originally recorded. But if you turn this On, then you can control the dynamics of the step with your key strike. Depending on how hard you strike the key, the K2 will adjust the velocities of the notes in the song. The velocity of your key strike is treated as a percentage (scaling factor), so a trigger velocity of 100 would give you the original velocities. A triggering velocity of 50 would scale all velocities to 1/2 of their original values. And a triggering velocity of 127 would scale all velocities to increase them by about  1 and 1/4 of their original value. (Of course, any value above 127 would be pinned at 127.)

  5. Now select step 2, and assign it to a key or range of keys. If you have more steps, assign each step to a key or range of keys. Set the Latch to On for each Step. Now strike one of the keys assigned to step 1 and let it play through the entire step. Notice that it begins playing step 2 after step 1 is finished. As long as the Mode is set to Next, the K2 will always move to the next step after finishing the current step, whether or not the steps are assigned to keys. If you only want a step to play if you strike the appropriate key and not advance to the next step, make sure the Mode for each step is set to Stop.

Triggering Steps in Advance of the Beat

Normally, a step is triggered the moment you strike the key.

But for K2500 (OS v4.21 or better), K2600 and K2661 users there is also an added feature which will allow you to strike the key in advance of the down beat (beat number 1) and not have the new step start until the end of the current bar is finished (this feature is not available in the K2000 series).

To set the K2 to perform this function, you will need to edit the Control Setup. Go to the MIDI Transmit page, select the Control Setup parameter and press Edit. You will jump into the Setup Editor. Press the left More button, then the COMMON button. Turn the Sync parameter On. Then save this Setup (you may want to Rename it). That's it.

Of course, a regular Setup can be used to call up a Song when the Setup is selected. If you are doing this, you would want to edit the Sync parameter in that Setup, instead of editing the Control Setup.
