[. . . ] In general, raising the value of Xpose decreases the duration of each amplitude-envelope segment, while lowering the value of Xpose increases the duration of each segment. The User Envelope You can use one of your own amplitude envelopes instead of the layer's natural amplitude envelope. On the AMPENV page for Layer 3, change the value of the Mode parameter from Natural to User. This removes the default amplitude envelope, and applies a user-defined envelope according to the values of the parameters on the AMPENV page (Att1, Dec1, Rel1, etc. ). In this case, it doesn't matter which keymap you assign to Layer 3. 2-8 Triple Modular Processing Editing Triples Summary of Amplitude Envelopes in Triples Because of the special nature of triples and their interactions with amplitude envelopes, you'll need to give some thought to the amplitude. in each layer of the triples you program. There are three primary points to remember, each of which significantly affects the sound of a triple: · · · The optional use of AMP blocks in Layers 1 and 2 (which determines whether Layers 1 and 2 use their own amplitude envelopes) The keymaps (if any) in each layer of a triple (which determine the sound produced by each layer) Choosing natural or user amplitude envelopes, especially in Layer 3 Other Considerations Triples are a lot like normal layers, but there are a few important differences. Processing-Only Layers Layers that use Algorithms 81­127 can be processing-only layers--that is, they can provide additional processing for the audio output of other layers, without generating their own sounds. (They can provide additional processing and produce sound, as you'll see. ) Layer 1 of a triple usually generates sound via sample playback (unless it uses Keymap 0 None or 168 Silence). In other words, the sample playback of Layer 1 is routed to the input of Layer 1's algorithm. In addition to processing sample playback, most of the Layer-1 algorithms (33­62) can also generate waveforms within the algorithms themselves, using DSP functions like SINE and SAW. For some of the Layer-2 algorithms (63­80) the input is the sample playback from Layer 2, mixed at one or more points with the output from Layer 1. For the remainder of the Layer-2 algorithms (81­100), the only input is the output from Layer 1; the sample playback from layer 2 (if any) is not routed to the inputs of these algorithms. Most of the Layer-2 algorithms can also generate waveforms within the algorithms themselves. The input for all of the Layer-3 algorithms is the output from Layer 2. These algorithms never process the sample playback (if any) from Layer 3. Like the other algorithms, however, they can generate their own waveforms. Since layers that use Algorithms 81­127 don't process their own sample playback data, they have no pitch parameters, and their algorithm diagrams contain no pitch blocks. When you're editing a layer that uses one of these algorithms, if you press the PITCH soft button, you'll see a blank page. Layer Parameters Since a triple is essentially a single layer (except that it uses three voices per note), it has a single set of layer parameters. You can view and edit these parameters by pressing the LAYER soft button when Layer 1 of the triple is current. If you press LAYER when Layer 2 or 3 is current, you see a blank page. Output Parameters Triples have a single set of output parameters controlling all three layers (again because triples are essentially single layers). You can view and edit the output parameters by pressing the OUTPUT soft button when Layer 3 of the triple is current. If you press OUTPUT when Layer 1 or 2 is current, you see a blank page. 2-9 Triple Modular Processing Editing Triples New Combinations of DSP Functions Seven new two-stage DSP functions combine a filter or double shaper with a gain function (the gain occurs after the filtering/shaping). One or more of these functions is available in most of the two-stage DSP blocks. They're listed below. LOPAS2 GAIN HIPAS2 GAIN BAND2 GAIN LP2RES GAIN SHAPE2 GAIN LPGATE GAIN NOTCH2 GAIN These functions are equivalent to two single-stage blocks in a v1. 0 algorithm--a block using a filter or shaper followed by a block using the GAIN function. Stereo Keymaps Because of sound-processing requirements, triples can't use stereo keymaps. [. . . ] If you change partitions while the free-space information is visible, the K2600 automatically calculates and displays the free-space information for the new partition. Exiting the DiskUtil page disables this automatic updating until the next time you use the Free utility. List The List utility is a convenient way to view the directories and files on your hard disk. When you press List, the display shows a hierarchical listing of all the files and directories in the current partition (this can take a while, depending on the size and complexity of your directories). Use the Up and Down cursor buttons to select different objects in the list. [. . . ]
