Alesis K2661 Midi Control of KB3 Programs, KB3 Mode Buttons and Corresponding Parameters

Program Mode

KB3 Program Structure

can change the effects in real time by pressing the buttons (or by sending the appropriate MIDI Controller values from your MIDI controller).

In normal operational modes, using the Mute buttons to change a program’s KB3 effects doesn’t affect the program; the effects return to their programmed settings the next time you select the program. If, however, you’re in an editor when you change the effects, you’re actually editing the program. If you like the changes, you can save the program with the new KB3 effects settings. If you don’t like the changes, you can exit without saving, and the program will revert to its previous settings.

The Mute buttons also send MIDI Controller information to the K2661’s MIDI Out port. See Column 2 of Table 6-3to check which Controller numbers the buttons send.

Of course, you can change the programmed settings for the KB3-mode buttons. For each of the buttons, there’s a corresponding parameter in the Program Editor.

MIDI Control of KB3 Programs

When you’re playing a KB3 program from an external MIDI source, there are two things to keep in mind:

•Certain MIDI Controller numbers always control specific KB3 features

•The value of the LocalKbdCh parameter affects how KB3 programs respond to MIDI Controller messages

Controller Numbers

Table 6-3lists the MIDI Controller numbers that control KB3 features. The first column lists the Controller numbers that KB3 programs always respond to (the K2661 also sends these Controller numbers to its MIDI Out port when you’re using the local keyboard channel—we’ll say more about that on page 6-7). KB3 programs also respond to the Controller numbers in the second column; these are the Controller numbers that the Voce™ MIDI Drawbar Controller uses to control common tone wheel organ features. Whatever kind of external MIDI source you’re using, you can use the MIDI controller numbers in either the second or third column to control the corresponding KB3 feature in the first column. For example, to control Drawbar 1, you can send either MIDI 6 or MIDI 12.
