Can't get Portamento to work.

[P.T.]

I have tried in both Tracktion and Reaper.

I have the notes overlapped.

I have cc64 set to 127 just before the 2nd note and then back to 0 before the next note.

I set cc 20 to a middle value ( around 60, but have tried other values as well).
The potamento knob on K2 moves as expected when the playback reaches the cc data.

I am using a sustain patch and have tried a few different ones.

There is no portamento glide from the 1st to the 2nd note.
I can hear that the hold pedal is working and the note attack is gone.
The 3rd note has the pedal up and I hear the full attack on the 3rd note.

I know what portamento sounds like as I use it with various synthesizers.

How do I get portamento to work?

Have you tried setting the velocity of the second note to a lower value than the first note? In Sonar, the strength of the slide can be heightened or diminished by how much difference in velocity there is between the first and second notes. John

I just tried changing thr velocity.
Nothing.

I'm getting zero portamento. No glide at all.

Hi, I'm not familiar with the programs you are using. Are you able to do a screenshot that would show the overlapped notes, CC#64 data, etc.?

[P.T.]

I've done screen shots in the past, but lately I can't seem to get it to work.

It looks like many things aren't working lately...possibly including me.

OK, I figurd out the screen shot.
Now I have to figure out how to add an attachment.

Oh, it seems they don't do attachments.

P.T., I use a free account at photobucket.com to host any image files I want to use.(or any webpage to which you can link will work)
Once uploaded to your account there, you just click on IMG, copy the link,
and paste it into your post here.

I hope you can add the screenshot, and the membership here will help to figure your problem out. John

[P.T.]

Thanks for your attempts to help Bigears.

I found a tutorial by Hannes that cleared up my problem.

He explained that the cc64 message has to be before the 1st note if you want the 2nd note to be reached by portamento.

So, if there are 2 notes and the 1st is to be played normally and the second is to be played portamento then there has to be a cc64 before note 1 and a cc20 message after the cc64 but before the 2nd note.

So, it works for me now.

P.T., Glad to hear you are up and running.

May I please re-open this thread? I'm having the same problem P.T. had with Traktion and Reaper... only in Sibelius 5. I know I'm kinda slow with the cc controls and so, but... a little help to get the portamentos running, please?

[P.T.]

I have never used Sibelius, so I don't know if anything else will be involved with the solution.

You have 2 notes.
You want to glide (portamento) from note 1 to note 2.
First you need to put a cc64 message of 127 (or above 64. I think 64 is the cut off point). That's the hold pedal.
Then, before note 2 you have to put a cc20 message which tells the program to do a portamento glide on the upcoming note. The larger the cc20 number, the longer the glide time.

Let us know how that works out.

Oh, if your glide time (portamento number) is too long and your 2nd note length is too short you won't hear the glide.

Hi, javiperillas

The information on this thread about using Portamento applies to audio/MIDI sequencers where MIDI data is easily and directly edited. I primarily use Sonar, where doing things like what P.T. described is an every day task.

But I also use Sibelius when I want/need decent looking hard copies - There are many people with more Sib experience than me, but I'm not aware of how you can do this kind of detailed MIDI manipulation in it. Trying to get a presentable recording out of Sib is a huge struggle that I find not worth it.

That's why so many people use both kinds of programs - You want to work your MIDI data and produce good recordings? Then use a sequencer. You want pro looking printed scores? Then use a notation program.

There may be approaches and tricks I'm not aware of in Sib - but I don't think the fine points such as getting Portamento to work reliably is something that can be done in Sib.

I'll have to try. And if not... as rbowser said, I'll have to try and find a sequencer.

Thanks to both of you for your answers!
