Hello All, I've now rer
 

Hello All,

I've now reread this thread, which is growing by the day!

You all want some solutions to problems here, so this post will propose some solutions. You can let me know here if they will significantly help.

First, a brief introduction: There's a two-way road between MIDI and notation. MIDI to notation is called "transcription". Notation to MIDI is called "musical interpretation". We should be clear about the distinction when we discuss and solve these problems. I will propose some solutions that deal with both transcription and interpretation in a uniform way that deals with both directions between MIDI and notation.

Ian reports that Composer’s transcription is inconsistent. Transcription is inconsistent if, given exactly the same MIDI file, the resulting notation is different. I highly suspect that Herbert experience of inconsistent transcription is due to different Transcription Options settings being applied at different times. With exactly same set of Transcription Options and the same MIDI file, the same notation should be produced. It's possible that some additional factor alters the resulting notation; but I have not ever observed exactly the same Transcription Options and same MIDI file produce different notation. I think the problem here is that the user is unknowingly applying different Transcription Options at different times.

My proposal for solving the problem identified in the previous paragraph is that the Transcription Options dialog will let the user set one or more “transcription profiles”. Take a look at Sherry’s screen shot of the Transcription Options dialog box near the top of this thread. There would be an extra place in the Transcription Options dialog box where the user could say, “Please remember exactly all of the checkmarks and settings in this dialog box, and give those settings the name ‘My Options.”

Now that you have a precise set of Transcription Options associated with the options profile name ‘My Options’, you can confidently recall those options when re-transcribing a MIDI file, with assurance that the MIDI file will transcribe to exactly the same notation.

Going the other direction, from notation to MIDI, is called “MIDI interpretation”. It has been pointed out in this thread that Composer does no MIDI interpretation, while other notation apps out there do. That’s quite true. That will change. In the last 18 months, I’ve already done a lot of unpublished work in the area of MIDI interpretation of notation. That includes interpretation of markings such as accent marks and dynamic mark. To be honest, I had not planned to also include swing rhythm interpretation, but that will be easy to add. These interpretation features will be delivered in Composer 3.0, which release date I cannot commit to yet.

Included with the interpretation feature will be the equivalent of the ‘My Options’ proposed above for the Transcription Options dialog box. The user will be able to control the musical interpretations with quite a few knobs. The user will be able to save distinct sets of musical interpretation knobs settings with one or more ‘My Interpretation’ names. Thus, there would be a close parallel in how the user can save and recall options for both directions between MIDI and notation: transcription and interpretation.

The above solution does not claim to solve every problem related to transcription that has been discussed in this thread. If we admit that perfection is impossible in transcription and interpretation, would you find the above solution a big step forward for Composer 3.0?

P.S. Sherry sent me an email pointing out that it was Ian, not Herbert, who reported inconsistent transcription. So, I edited the above post accordingly. If you got an email notification of the post, the email will say Herbert instead of Ian.

Hi Mark,

You said:

“I highly suspect that Herbert experience of inconsistent transcription is due to different Transcription Options settings being applied at different times.”

No, I have not complaint about any inconsistent transcription, but pointed to a consistent reinterpretation of my notation while editing a .not file. Please read again my post of Monday, February 23, 2009 – 5:47 am.

Here is a step by step procedure to demonstrate what I mean.

1. Start a new song with a 5 line drum staff.
2. Place a 1/16 note for a tom at the end of the first measure.
3. Place a 1/16 note for a bass drum at the beginning of the second measure.
4. Convert the 5 line staff to single line staves
5. Convert the single line staves to a 5 line staff.

The result is that the tom has now become a grace note in the second bar.

Best wishes,

Herbert

Dear Herbert

I've just come to the forum after a busy day (UK time) and I'm reading the posts in chronological order. I've got as far as your February 25, 2009 - 3:25 am: post.

I'm am sorry you found anything in my post at which to take offence. I am totally at a loss at to what it might be, but I respect your knowledge and contributions, and I therefore express my regrets anyway.

I've already upset Herbert unintentionally; so I think I should point out that you are possibly (?probably) attributing to Herbert comments and faults that are mine, not his .

And Mark again

Having now read the whole of your your Wednesday, February 25, 2009 - 12:43 pm post, I have to say that all sounds brilliant. Can I just put in a plea that, where practicable, it should be possible to specify one's preferences by means of numerical values (e.g. perhaps the size of the 'envelope' within which Composer will deem midi sounds to be 'simultaneous' for the purposes of transcription)?

Power to your elbow (s) !

Hello, all I think I'm
 

Hello, all

I think I'm up to date now!

It seems to me that part - just a part - of the 'problem' we've been masticating so thoroughly is (paradoxically) that Composer is normally such an excellent transcriber. When a bar or two are not transcribed as one might like, one need is to 'see the midi', and what might help with that is a notator which is far cruder than we expect Composer to be. I've been looking around, and there's a little freeware sequencer called Anvil Studio, which I wouldn't want to have to look at for more than a few minutes at a time, but which I think might serve as a sort of microscope to 'check the midi'. What I envisage is to use Composer's excellent copying tools and the 'new from clipboard' route to make a 'mini' midi file to put 'under the microscope'.

That's the plan, anyway/ If it provers useful, I will report back.

Hello Herbert,

The result is that the tom has now become a grace note in the second bar.<!-/quote-!><hr size=0></blockquote>That's a good trick you played on Composer to trip it up. Composer's counter move in this game is to go to the Setup / Transcription Options command, and turn off the checkmark for Transcribe Ornaments / Grace Notes. Now the 16th note is restored in the 5-line staff as a 16th note rather than grace.

Your move next ;-)

Thanks for your February 26, 2009 - 11:28 pm: suggestion. Yes, I can see the logic of that and it well be helpful. I'll bear it in mind next time I'm in 'that position', and let you know.

Thanks for all your attention to this issue.

Hello Ian,

I started to write up a tedious set of instructions for how to use piano roll to do this. You can take a pair of notated 8th notes, and hit the "33" key to change them to a notated and performed swing. That much is easy to do, except that you have to do it a pair of notes at a time, which is tedious. It gets even more tedious, however, to then keep the performed swing rhythm in tact while restoring the written-out swing to a simple pair of 8th notes again. This was so difficult to do, that I recommend that you don't even try it. If I can't figure out how to do it easily, there are only a few other people who have a chance of pulling it off (eg, Sherry and David).

So, I hate to say it, but there just isn't a good way to instruct Composer to interpret the 8th note pairs as a performed swing rhythm. That is a very common need for jazz. Other notation programs support this. So should Composer.

In the upcoming version 2.6, I'll add a swing interpretation feature that will make it easy to do this. When you see that feature in 2.6, you can say to yourself, "I got that feature added to Composer!"

It's task #2082.

By the 'Crann Rule of Proportions' (cf her post in this thread Friday, February 20, 2009 - 9:26 am ), a lot of people will be very happy with 2.6 ! Look forward to it.

Thanks

Dear Mark

Thankyou for taking so much trouble. It's absolutely fascinating.

Yes, it is a Biab-generated 'solo', and I think your diagnosis is a remarkable vindication of Biab's musicality - what you are demonstrating empirically is the mechanics of a 'laid-back' feel. I've just paused in writing this to listen again to the midi file without any score or visual parallel, and I think it sounds very musical, in its type. Wouldn't you agree ?

As to the *.not file / transcription, well, refer to my earlier descriptions of the different ways I might use the file. I find the process you lay out perfectly acceptable if it's what the situation requires. I think in practical terms, I'd probably clone the stave, and have one for sound and one for score, muting or hiding according to my purposes.

It's also interesting that the process shifts all notes equally - so the 'distances between them' are unchanged, and yet the transcription changes. This seems to imply a note's relation to the (metronome) beat is more influential in the transcription than its relation to the preceding and following note(s). Is that right ? If so,(a) is the 'snap to grid' setting relevant, and (b) might a 'tweak' to make the 'distances' relatively more important be a future possibility ?

Intriguing stuff. Thanks again for your trouble.
