Changes Script Buffer Operations

Each of the 8 Voice Setups has associated with it 4 general-purpose input buffers, each of which can hold up to 256 notes.

In the simplest case, you would use the Buffer Copy ( BC) command to capture a series of live input notes to a buffer. You would then use the Input Select command to tell a voice to take its input stream from the buffer, instead of the live input. The voice would then play those captured notes, automatically repeating when it reached the end of the sequence. In essence, this creates a dynamic Note Pattern.

You can use this sequence as a melodic motif or theme, which you can then modify to allow subtle or dramatic changes over time.

You can copy the original to multiple buffers, modify each differently, and then use Input Select to play them in each in turn but still keep the original to be able to return to the theme.

Or you can make only one copy which you keep modifying as it plays, periodically refreshing it from the original before embarking on a new series of modifications.

You can take a short original note sequence, and copy it multiple times to different positions in the same or another buffer to make a longer repeating sequence. You can then modify small sections while retaining the overall theme.

You can use the Set Pointers command to cause a single buffer to loop on any section you choose, in either direction. This allows you to treat a single buffer as a collection of smaller buffers, which you can employ as needed during the performance.

The Buffer Copy command alone can be used for many modifications, by replacing selected sections of buffer notes with new live input notes, or by moving sections around, or by copying sections with the note order reversed. The complete set of Buffer commands includes:

• Copy
• eXchange
• Pivot
• Add Value
• Fill
• Velocity and Chord Maps
• Repeat Notes
• Repeat and Note Adjust Maps
• Set Pointers
• Note Values
