THE GENERAL GRAPHICS AND THE MIDI OPTIONS DIALOG

BOXES

The MIDI Options Dialog Box and the General Graphics Options Dialog Box are the

essential elements of control in WaveWare. They are the means by which musical setups and

graphs of processed data are created and modified. In addition the General Graphics

Windows are responsible for exporting data as both ASCII and DDE streams. Both types of

dialog boxes have many features and deserve close scrutiny.

The two types of dialog boxes are separate. Changing the MIDI Options does not change the

General Graph. This allows a great deal of flexibility in designing configurations but

necessitates a certain amount of attention. If you have a MIDI and General Graph window

that are representing a similar signal characteristic, you may want to change one if you

change the other.

The settings for General Graph and MIDI will ordinarily be different. In the MIDI Output the

output parameters define the upper and lower thresholds of the MIDI output. In the General

Graph output they define the top and bottom of the Y-axis. Usually the General Graph output

has a wider range than the MIDI output. If the settings are the same, then the line goes off the

graph when the signal goes outside threshhold.

The MIDI Options Dialog Box and the General Graphics Options Dialog Box make use of

the same input algorithms. All input algorithms are displayed in all MIDI Options Dialog

Boxes, but only those input algorithms that match the use category of the selected General

Graphics Dialog Box are displayed. (e.g. Heart input algorithm is displayed in all MIDI

options dialog boxes, but is only displayed in heart General Graphics Dialog boxes).

This section is organized as follows: First a description of the fixed portions of the MIDI

Options Dialog Box and the General Graphics Options Dialog Box. Then each algorithm

will be described in turn.
