Chapter 5: Editing Mixes

Once in Mix Edit Mode, use the [0] - [9] and [00] - [50] buttons to select a MIDI channel to edit (1 – 16). Use the [60] – [120] buttons to select a Function Group (Level, Pitch, Effect, etc.) If a Function Group has more than one parameter, use the [▲ PAGE] and [PAGE ▲] buttons to locate a specific parameter. The Mix Edit functions and Channels are written in blue above or below each numbered button, on the line labeled MIX.

Each channel of a Mix may be enabled or disabled, without changing any of its parameter settings. When a channel is disabled, its marker ( ) will not appear in the bottom right corner of the display when Mix Play Mode is selected. You can set levels, effect levels and bus assignments, pitch transposition, keyboard ranges (if making a split or layer), and MIDI parameters for each individual channel. A Mix also uses the Effect Patch associated with one of its 16 Programs.

Here is a simplified diagram of the signal path in Mix mode.

UNDERSTANDING THE EDIT BUFFERS

In Mix mode, there are 16 edit buffers (one for each channel), plus another buffer for the Mix parameters (Level, Pitch, Range, etc.), and yet another buffer for the Effects Processor. When you select a Mix from memory, it is copied into the Mix Edit buffer, the 16 Programs of that Mix are copied into the 16 edit buffers, and the Effect from one of the 16 Programs is copied into the Effects buffer. If you make changes to the Mix, they are only temporarily kept in the edit buffer until a new Mix is selected from memory. Therefore, you MUST store your edited Mix if you want to keep it.

If in the course of making a Mix, you enter Program Edit mode (by pressing [EDIT SELECT]) and edit one or more Programs in the Mix, the edits you make are entered into a separate buffer for each Program in the Mix. Note, however, that you DO have to store each edited Program into the User bank (in the same or different Program number location) before selecting a different Mix, or your changes will be lost. The same goes for editing the Effects, which will be stored along with its associated
