how do you edit duration notes CW Pro9

[steveb]

I have a midi that has "all" the notes in the drum track with "zero" duration value and there is no sound. Does any body know how to edit the duration to all the notes so that the drum track cam be audible.
I am using Cakewalk Pro9

[frankie]

Editing Notes From the Staff View: Click a note using the right mouse button. Cakewalk displays a Note Parameters dialog box which lets you edit all note parameters, including some that the Staff View doesn't display.

The parameters you can edit are: Time, Pitch, Velocity, Duration, and Channel.

Thanks frankie,

That will do one note, but there hundreds to change. I need to find a way to change all the notes at once. not one by one

[frankie]

There is a way to change durations for 1 note as a batch can't remember where it is.You have to do all D1 then C1 etc.
Will take some more Ginko and get back to you.

Hahahahaha good one frankie, thanks for your help. whats happening is, all the notes are on zero duration and I can't increase the number to make the notes audible. I am still persisting as well.

[frankie]

Edit..........Interpolate.....note/aft.....enter range and increase
remember it is drums and I think all you need is a number above 10.
John G posted a Cakewalk instruction manual here last year.If you dive into the archives you may find it.

Steve, Quickest way is Highlight the whole drum track and use the Quantise function, don't quantise the start times (unless you want to and if you do be sure you don't use a small value) just quantise the note value, set the Quantise to 32nds or some such.

The problem with 0 durations is you can't multiply a zero! LOL

UPDATE: It doesn't always work, with Quantise I just found out by experimentation. Using Interpolate, works every time.

Highlight the track >Edit>Interpolate> clear all the check boxes by clicking None and then just tick Notes>make sure Duration is showing 0 in the first box>click OK>in the next screen set Duations to 15 and 15> Click OK. Done!

I'll email you my new phone number, mate. (sent it to your Hotmail, you know mine at gibboco, I think).
Gimme a call if you still can't figure it out.

Cheers, Gibbo

THANK YOU, THANK YOU, THANK YOU it worked.
I never would have thought of using Interpolate. thanks again, much appreciated.

As you found out, Gibbo, quantise just affects the start time of the note(s). What is needed is to change the note duration (or Gate Time as some call it) and your edit interpolate should work fine, changing all instances of 0 duration to 15. Actually any short duration greater than zero should work okay (N.B. should) as percussion is a "hit" note rather than a "held" note.

In the strictest sense I believe that percussion should work with no "note off" event, just a "note on" which appears as a note with zero duration, and that's what we have with this particular drum track. But all sequencing programs I have knowledge of always put in a note on and off. At least I think so.

I might do some research on this.

Right, John, but in CW9 the quantise can be used for BOTH/EITHER start times and note duration, If you want to just Quantise the durations you just need to untick the start time box in the menu, that way the start times are unaffected.

It works fine on any duration but 0/zero is an exception, you can't quantise "nothing"! LOL

The Interpolate action works fine in all cases.

Hi Gibbo,

I accept that CWPA allows you to edit note durations in the quantise function, but strictly speaking "quantisation" is about the closeness, or otherwise, of the beginning of a note to the beat. By definition.

See wiki en.wikipedia.org/wiki/Quantization_%28music%29

Even if a MIDI 'note on' has no corresponding 'note off', that MIDI event can be brought closer to, or taken further from 'the beat', whether CWPA allows it or not, by adjusting the delta time that precedes the note.

In actual fact 'note duration' only exists as a calculation made by the sequencing program. There is no 'note duration' of any note held in any MIDI file. Merely the delta time of a 'note on' followed, in most cases, by the delta time of the 'note off'.

It looks like this e.g.

delta time,
note on, channel n, note number, velocity (>0), as a 3 byte message, (90H 60 64)

later

delta time,
note off, channel n, note number, release velocity, another 3 byte message, (80H 60 00)
or more likely,
note on, channel n, note number, velocity = 0, which can be two bytes if the status byte hasn't changed from the previous message.
(90H 60 00, or just 60, 00)

We can then adjust the delta time immediately preceding the note on (> 0) to affect quantisation and, of course, the delta time preceding the note off to affect duration. In fact, normally when we quantise a note, both delta times are altered.

So you can quantise nothing, as you put it, except, perhaps in CWPA.

Delta times are calculated by the sequencing program from a combination of ppqn and current tempo to give an elapsed time in milliseconds from the start of the file.

Any use?

[gibbo]

Yes, that's understood, John.
Still. it's a handy little shortcut for those wishing to alter all note "durations" to a particular value in one fell swoop. eh?

[JohnG]

Indeed it is!

But I've always used interpolate. Not adventurous enough I imagine. Oh well!

Hide bound by convention, that's me!
