There is a checkbox under Generation Parameters that will apply rectification to
each generation, if you want that.

Assuming you mean editing the textual representation, yes that works. If I were
to investigate automation of the feature you desire: preserve contour but vary
durations, it would probably be based on editing the textual representation.

The rhythm variation feature could be explored in the future. I'm not sure where
it should be placed priority-wise.


Thanks for your comments.

Thanks very much, I think all the features you mentioned are incredibly useful,
and your answer helped me understand better.

For the melody/rhythm combinations I listed, I understand that the steps for the
second option should be completed with 'rectification'. (Maybe inverting the
melody could also be listed in this category?)

For the last option (changing rhythm, preserving contour) could there be a
semi-manual way (I mean, if we want to try hard) like:
(for each generation)
>edit durations in extracted abstract melody in the Lick Generator window
>Fill Abstract Melody
>rectify if needed
?

Also reverting the melody, then shifting notes up/down to restore original order
of pitches might work, but we would get just one different rhythm.

Of course, getting a series of durations computed by a utility would be easier
(with parameters: number of notes, selectable min and max durations, total
duration not to exceed that of selected region).

I would like to ask your opinions... Thanks again.

Regards

John,

I'll give it a try. You probably know some of this, but here goes ...

Last thing first: There is currently no way to preserve contour but change
rhythm, except for the edit buttons Expand/Contract Melody by 2 or 3. These just
change the durations uniformly.

To get an Abstract Melody in the Lick Generator window, you can select some
slots with chords, then either:

a. press Generate Melody, which will first generate an abstract melody, then
also fill it with a real melody, or

b. press Generate Abstract Melody only, or

c. Extract the abstract melody from the leadsheet, by selecting the slots from
which to extract, then pressing Extract Abstract Melody.

If you then press Fill Abstract Melody, it will always preserve the rhythm.

Fill Abstract Melody will preserve the contour only if the abstract melody is
composed of "slopes" rather than individual notes. For example, if you Extract
Melody, you will get slopes.

The current default grammar ("My" Grammar) does not generate melodies with
slopes, but the learned grammars, such as Charlie Parker, etc. do.

You can also get other melodies with the same contour by using harmonic
transposition: (in version 4.07) s transposes the melody down a step and w
transposes it up a step, approximately preserving contour while snapping the
notes to chord and color tones. Furthermore, these will snap the result even if
the original was not compatible with the harmony.

If you use Extract Rhythm instead of Extract Abstract Melody, the abstract
melody will have the rhtythm, but note categories will all be X, meaning
arbitrary.

If you fill a rhythm-only abstract melody, it will preserve the rhythm, but the
note choices will be pretty arbitrary. (They will obey min and max interval
values set in the Generation Parameters window.) You can use harmonic
transposition or rectification to snap the notes back into the harmony.

I hope this clarifies. Please ask again if there are more specifics.

Thank you for trying out some of the less-used features of the tool.

Regards,

Bob Keller

Could you correct me with (and help completing) the possibilities of generating
a new melody (using the lick generator) while:

-Preserving both melodic contour and rhythm:

>Fill Abstract Melody

-Preserving rhythm, changing melodic contour:

(Can this be done?)

Pierre,

I'm sorry, there currently is no way to have more than one melody line at a
time. This feature might be added in the distant future.

Bob

Hello,

Is there a way to enter polyphonic solo into a chorus ?
Thanks for your help

Santiago,

Currently there is no means of saving portions of the vocabulary in a separate
file from within Impro-Visor itself. Here are some ways you can work around the
issue. (Note that the vocabulary file is a text file, so you can edit it. Just
be careful to keep the parentheses matched.)

(1) The licks you've added will always appear at the bottom of the file. So just
note the last of the original licks, and that can serve as the marker for where
yours begin, or

(2) There is a required name field when you save a lick, so just put your name
or initials in that field (you can include other info as well). Unfortunately,
we don't yet have a way of calling up licks only by name, but you will see the
names in the menu, or

(3) If you don't need any of the licks that come with the distribution, you can
edit them all out, then every lick will be yours.

I hope this helps.
