Deleting unwanted controller events

[freeway]

Hi Guys.. ....been searching the boards looking for an answer before I posted this with no luck....my prob is Im recording onto the onboard sequencer in my PSRS700 using the preset styles then adding in extra tracks manually .....then when finished loading it into Cakewalk Pro 9 as Im trying to make up some midis for myself......the prob is in playback its stuttering in parts I realise its controler events thats causing this ...and Ive identified batches of events at theproblem areas the main culprit being Contoller 84 Potamento......dilemna now is firstly there seems to be over a 100 of them in the one sequence ....is it safe to delete these or will it have a knock on effect to the sequence .........and if I can is there a way to batch delete them...Iknow by using the Interpolate function I can replace and change the values but can I also delete them ........deleted them all manually in another sequence and that was a lot of work I tell ya but the seq played fine after that ....was I just lucky or what ?.....so appreciate any help on this for future reference.......is that controller 84 event something to do with the slide and chord changes ? many thanx............regards......Barry

I'd have to hear and see the sequence to know if deleting the portamento CCs would hurt the sound. If you want, you can send it to me and I'll have a look. Portamento is controlled with three Controllers. CC-5 (Portamento Time) CC-65 (Portamento On/Off) and CC-84 (Portamento Control).

You should be able to delete CCs in mas by opening the event list and filtering out all other events so all you see is those CCs in which you want to delete. Then hilight them all and delete. I also delete things in mass by doing it in the Graphic Controller pane, which is located below the piano roll. I shrink the bars down so I can see as many as I can then I get the eraser and just sweep it across them. Bingo, they are gone.

Cheerz Cat.. .....I suppose its just trial and error using the undo function if it puts the song out .......how do I filter out all the others in the Events List to be able to delete the ones I want ..........cant find that graphics control pane either Im using CWPA 9......thanx Barry

Hi Barry,

Deleting any of these kind of events is "usually" not a problem. What I do is make a backup of the file first before experimenting. IMO very important in case one hits the wrong key! Then, as I do the edits, I do a few, play it, and if it's okay hit save. Do a few more, check, save. etc. If you have done too many then you can use "undo" to get back to the last good one, then go again.

If you look at the track with loads of portamentos in it in the "list view", you will usually find that they are very close together in time. Sometimes even several "CCs" on a single MIDI tick. i.e. 3 CC84s at say 09:01:001 then another 3 at 09:01:002 and so on. It is this "too much MIDI data" that makes the tune stutter as, I guess, you already know.

Usually you can safely remove most of these so that you have one CC84 say every 10 ticks i.e. one at 09:01:001 the next at 09:01:010 and so on. But you may even find that that is too many, and can thin to one every 20 ticks or even more widely spaced.

How much you can thin will depend on two things. The resolution of the sequencer (most today are 480ppqn), as I recall you can set CWPA9 to this, the other thing is the tempo of the song. At fast tempos bigger gaps at slower, fewer.

But, there is a "thin controllers" command, if I remember correctly, as a CAL routine within CWPA9. I will try to find it for you and let you know. I'm sure I used it for someone just before Christmas. There is a terrific one in XGworks which will progressively thin control values, but I imagine that isn't much use to you?

Back soon if I can,
JohnG.

Thanx for your input John .........how do I filter out the ones I need to batch delete in CW? otherwise it could take forever doing them manually one by one Cat mentioned this but not sure how to do it ...thanx again....regards......Barry

--This isn't the same as Cat's way! --

It sure isn't. My way was mass deletion, not thinning. I didn't even think of thinning them out. Shame on me. Good thing you are here to clean up my messes, John. LOL!!!

[freeway]

Thats great info John appreciate the effort thanx ........prob I got now is aint got no cal prog in CWPA 9 ......well reinstalled just to be sure saw it there beside the cw exe setup file called add ons but it had no way of loading it in.......... but how do I insert them into the prog itself ......thought it would automatically load .....or do I need to download the cal files seperately ? ..............btw this prog is just a copy damaged the original ...Cheerz

... For Cat. . ya Id say mass delete at this stage too somehow ....how do I filter out all the others in the Events List to be able to delete the ones I want ..........cant find that graphics control pane either Im using CWPA 9......thanx Barry

[JohnG]

My pleasure Barry,
I'll zip up the set of CALs in my CWPA9 and post them to 4shared, then anyone can download them. Here is the link www.4shared.com/file/91916781/6d571955/CALroutines.html
Let me know if you get 'em okay.

Hi Barry,

If you can't see the controller pane then it has just got closed down. Open up the piano roll window and position the mouse pointer just above the horizontal scroll bar at the bottom of the piano roll window. The mouse pointer should change to two tiny, horizontal bars with two arrows, one pointing up the other down. You should be able to drag open the control pane. (Click, hold, drag, release.)



Guess it might look something like this as you drag the pane open!

Image modified on 10th Mar. 2009 to erase bits of the track view and leave only the piano roll with the control pane being dragged up from the bottom. (The speckled horizontal line.)

Thanks John ...got those files ok ..Ill give it a bash later on and see how I go....Ill let ya know ok.........many thanx

[JazzCat]

Hey John, that doesn't look like a graphics controller pane to me. That looks like a 'track view'. which shows CCs as vertical lines and notes as horizontals. Here's a thumbnail link to a pic of my piano roll shot of one of the Tune 1000 files I used for... well..... you'll see what I used it for. Anyway, it is showing pitchbend data, but I can use the down arrow next to the word 'pitch bend' and choose to see any CC data in the same way.
( Image Shack only gave me the code for a thumbnail but clicking on it will bring up the large version)

[freeway]

Thanx to you both Ive cracked it now ;D.....that'll save me a lotta time and hair pulling in the future I now have the option of deleting events and thinning events plus so much more you've opened up a new world to me here and I'm a happy bunny right now .. ..Cheerz.......Regards........Barry

[JazzCat]

Any time Barry! And, I bet I speak for JohnG as well. <smile> I'm just about ready to reinstall Cakewalk 9 again, ( if XP can handle it) because John is so darned good with it. With his help, I might slowly learn to cross over to other programs.

Hey John, I wouldn't gripe at some tutorials on XGWorks either ... (hint hint)

[freeway]

You ever heard of Murphys Law . ......well typically just as I was about to sink my teeth into this one the progs playing up again so much so I tried to reinstall it again ...d**n Vista..(cycle redundancy error) so if memory serves me right the disc is damaged .......anyway as I now have Sonar 6 and it seems to work best with Vista have decided to bite the bullet and install it....didn't before as I was comfortable with Pro9....actually gotta present of Sonar......the missus god bless her ;D. So anyway I presume this tutorial will apply to the newer ver also should be something similar I guess.....thanx again ..........Regards

Er,
I was trying to show Barry how to open the graphics control pane in CWPA9 when he had the piano roll open. It's possible to resize it using the mouse and thereby to close it completely. It means you have to grab the edge of it and pull it open again.

I have now edited the previous image to get rid of the bottom edge and show just the piano roll with the controller pane being dragged open. The pane only shows when you release the mouse! So all you see is a speckled line where the mouse is dragging the edge of the pane up.

Looks like I need to write a tutorial on how to import images from ImageShack too. LOL All the images I post here are hosted there. Now I wonder where to post that tutorial?

JohnG.

[JazzCat]

there is sort of a tutorial in the 'how to do stuff on the forum' board (or whatever it's called) I used it to get what I got up there, but I flat could not find how to have the large image show, vs. the thumbnail. I've had that problem before with Image Shack. I'd sure like to know how to avoid the thumbnail view! Maybe you could put a tutorial there? I sure would use it!

This is probably more info than required now but I do it this way (removing all controllers)

Select tracks to edit
Menu: Edit / Select / By Filter
Click "none" then choose event type or value etc...
Once selected, CtrlX to remove

cheers

You are absolutely right moonie, that is a good way of removing events if you can decipher what it is all about. Actually after a bit of experimentation and reading the help file it does become clear. But I have found that most people run a mile when exposed to this window. And I have to say that each time I use it I have to remind myself how it works! But work it does.
