How to execute 16th notes during 8th note swing?

Greetings,

How does one execute 16th notes in a piece of music
that has the indication that 8th notes are to be played
as "swing 8ths" ? And how would one accomplish this for
correct playback in NWC?

Thanks!

My guess would be "played straight," but I may be mistaken. Try it both ways to see how it works best for the particular piece you're sequencing.

If you set a tempo track as described in user tip #53 they will play "swung," depending on whether they occur on the downbeat or upbeat portion. (See also the other user tips linked to from that one.)

The 16ths are played straight. If they were to be played "swingy," they would be notated as dotted 16ths and 32nds (not a hard and fast rule, mind you).
I use the method described in user tip #103 myself, as I have found that one to be the least complicated.
If your tempo (for example) is q=84, then after creating a tempo track as instructed in user tip #103, simply place a new tempo mark [q=84] on the beat(s) that have the 16th notes. Pretty easy.

Thanks for the replies. What if the melody
has 16th notes, but the accompaniment has
"swing 8ths"? If I set the tempo as "straight"
during the 16th notes, the accompaniment part
will stop swinging.

Thanks again!

Now things get harder...

The only way I can think of is to explicitly write the swing 8ths as a quarter and an 8th, tripletted together, whilst the straight 16ths are .. er.. straight. This will of course restrict you to the "default" swing ratio of 33%. (Other possibilities do exist; for instance, a dotted 1/8 and a 1/16, giving a rather frantic 25%, or 1/16 tied to dotted 1/16 and another dotted 1/16 (gives a more laid-back 37%).

If you want to keep the visual look of two 8ths, you'll have to write two staves; one sounded but hidden, the other visible but muted.

Thanks for the tips!
