Frequency Asked Questions

<P>
|
|
This chapter will serve as a container for questions asked by
|
|
some enthusiastic
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> users. It may make some sense in the future to
|
|
distribute this information as a separate file.

<P>
|
|
When a real player plays chords he or she adjusts the position of the
|
|
chords so that they don't “bounce” around between octaves. One way
|
|
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> tries to do the same is with the “Voicing Mode=Optimal”
|
|
setting. However, sometimes the chord range of a piece is too large
|
|
for this to work properly. In this case you'll have to use the octave
|
|
adjustments in chords. For more details <A HREF="node14.html#sec-chordadjust">go here</A>.

Using

<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> variables and some simple looping, one might try something like:

</td></tr>

</Table>
|

|
|
<P>
|
|
Note that the “Print” lines are used for debugging purposes. The case
|
|
of the variable names has been mixed to illustrate the fact that
|
|
“Solo” is the same as “SOLO” which is the same as “solo”.

Now, if you don't like things that look like old BASIC program code,

you could just as easily duplicate the above with:

Where's the GUI?</A>

<P>
|
|
<SPAN CLASS="textit">I really think that
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> is a cool program. But, it needs a
|
|
<SPAN CLASS="textit">GUI</SPAN>. Are you planning on writing one? Will you help me if I
|
|
start to write one?</SPAN>
|
|
|
|
<P>
|
|
Thanks for the kind comments! The author likes
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> too. A lot!
|
|
|
|
<P>
|
|
Some attempts have been made to write a number of <SPAN CLASS="textit">GUI</SPAN>s for
|
|
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> . But, nothing seemed to be much more useful than the existing
|
|
text interface. So, why waste too much time? There is nothing wrong with
|
|
graphical programming interfaces, but perhaps not in this case.
|
|
|
|
<P>
|
|
But, I may well be wrong. If you think it'd be better with a
|
|
<SPAN CLASS="textit">GUI</SPAN> ... well, this is open source and you are more than
|
|
welcome to write one. If you do, I'd suggest that you make your
|
|
program a front-end which lets a user compile standard
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> files. If
|
|
you find that more error reporting, etc. is required to interact
|
|
properly with your code, let me know and I'll probably be quite
|
|
willing to make those kind of changes.

Where's the manual index?</A>

<P>

Yes,this manual needs an index. I just don't have the time
|
|
to go though and do all the necessary work. Is there a volunteer?
