Triplet notation in imported MIDI

2006-07-09 11:41 pm

When importing MIDI there seems to be a problem with triplets. e.g: quaver triplets seem always to be interpreted as dotted semiquavers. Anyone know any way round this (apart from doing it the hard way)?

G'day Andrew,
not in NWC1, however, NWC2 is a different story...

NWC2 has a "user tools" facility and there is a user tool for just this task. It isn't quite perfect, but it goes a loooong way to reducing the problem.

If you are using version 2, then one of Andrew Purdam's user tools will sort this out.

See :

and

If you are using version 1 - then the hard way

Thanks v. much guys - already used Andrew Purdam's excellent Parts tool, so I'll give this one a whirl!

Just given Andrew's tool a try, and it does work, but the question remains - why isn't this core NWC functionality by now? A quick scan of the forum shows that folk have been moaning about triplet import since at least 1999...

I always import using the maximum resolutions allowed - ie 64th notes and 16th rests. It doesn't make a lot of sense to me to use the default settings - why would you want to throw detail away? (I suppose there might be an argument for coarser settings if you're attempting to "quantise" a midi file produced by a live midi-keyboard-player, rather than a file produced by a different sequencer. I've never had much joy with such attempts in any case, since no keyboard player I know - including myself - can keep in tempo strictly enough to make the resultant import look other than a dog's breakfast...)

Anyway - if anyone doesn't realise the extent of the problem - just try creating a snippet using NWC2. Time signature 4-4, one bar consisting of a triplet of three crotchets (quarter notes) followed by a minim (half note). Export to a midi file and re-import using the maximum resolutions, and be prepared to chuckle at the result...

Cheers John Hinsley

I think that moving to version 2 and the User Tool mechanism will allow NWC to integrate a lot of tools now.
When you think about the triplet issue, there are several reasons for not doing it automatically, but I agree that an option for searching for and creating triplets upon import should be allowed. However it does get tricky with multi-voiced staves - but then that pushes NWC to the limit anyway.
