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.

<I>I've keyed in a song but some of the chords sound way too high

(or low).</I>

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="node11.html#sec-chordadjust">go here</A>.

<I>How can one define parts as part "A", part "B" ...and

arrange them at the end of the file? An option to repeat a ``solo''
|

section a number of times would be nice as well.</I>

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,

<I>I really think that
|

|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> is a cool program. But, it needs a
|
||
|
|
<I>GUI</I>. Are you planning on writing one? Will you help me if I
|
||
|
|
start to write one?</I>
|

<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 <I>GUI</I>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
|
||
|
|
<I>GUI</I> ...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.

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?
