No fingered portamento mode in EXB-RADIAS?

please any info.....

thank you.

Of course the EXB-RADIAS has Programs set up in fingered portamento mode, they are all in the I-F bank and are accessible once you've loaded the right programs and combis from Korg's web site.

But actually I am lying and you should not believe me. So, since you are selling your M3 tomorrow, let me know how much you want for it, I could do with a spare!

Regards,
Rob

Rob, trust me there is people as you know a lil about our music which they
wont consider buying even the greatest synth without Fingered Portamento,
i am personally one of them, a synth without it is completely useless to us
cuz no matter how good it sounds its not THAT without the Portamento.
I completely understand him and feel with him. Yes i said Useless and i mean
it in every literary way it is really useless, nothing to do with it except play
some chords or basslines, its what the music requires.

understand, thanks for your reply.

is very disappointed with the korg, if years of using these models. Once again, then did. Let us hope again in an update.

OK, what I understand as fingered portamento is selecting one of the EXB-RADIAS monophonic synth sounds that has the ability to automatically glide from one note to the next. Then I play a solo like from ELP's "Pictures at an Exhibition" or "Tarkus" in my right hand using the sound and automatic portamento from one note to the next, and the next thing you know is that Keith Emerson calls me up and offers me a job.

What do you guys understand as fingered portamento? Are we getting our lines crossed here?

Thanks,
Rob

What they want is do be able to control the Portamento as on regular PCM
Sounds i mean to turn it on and off and play value.
I cant confirm that on Radias yet, i have it but not installed.

Well that's easy as well, just assign the "portamento" version of the EXB-RADIAS program to one track in a Combi and then assign an identical program with the "mono" parameter turned off (ie without "portamento") to another track. Set both tracks to be played by the keyboard. Then using the track mute / unmute buttons on the control surface you can have your portamento cake and eat it. You can have poly+portamento, or just poly, or just portamento.

And once you've eaten some of this single-button activated portamento cake, it would be nice to get into a happier frame of mind and enjoy the party and throw out some of the garbage.

Best regards,
Rob

From what I understand, the correct definition of fingered portamento is where the note only glides to the next when they are played legato. when notes are played seperately there is no glide. a non-fingered portamento will always glide the oscillator from its previous position.

if you want to turn on/off portamento in a radias patch using buttons or sliders or anything else (expression pedal... I quite like using velocity too), I have this tip from my Radias-R:
assign the SW1 or SW2 (in Radias-R there are 5 external MIDI virtual patch sources, don't know how it is in the EXB) to portamento using the virtual patch slots. the amount value will be the amount of portamento to be applied when it is on/up/high/full.
make sure you set the actual porta in the pitch page to zero.

OK. Legato monophonic (which presumably corresponds to "fingered portamento") EXB-RADIAS sounds are those whose Voice Assign Mode is set to Mono, and whose Trigger Mode is set to Single.

You can then have a second copy of the Program where Trigger Mode is set Multi (ie non legato). You can assign both Programs to a Combi and you can arrange for velocity triggering to play the legato Program when you play quietly and to play the non-legato Program when you play loudly.

And you can have another similar pair of velocity triggered Programs in another pair of tracks in the Combi that plays the same sounds but with polyphony and no portamento.

You can then assign a controller or RPPR to flip from one mode to the other by muting and unmuting pairs of tracks.

First of all - a little definition so everyone knows what is meant by fingered portamento by me and, I believe, by xxxstudioxxx.

When you press a key, release it, and press another, there is no portamento and the notes do not glide. When you press a key and then press the next one without releasing the first (playing overlapping notes, called legato in music terms), there is portamento.

The Radias does not have this ability out of the box, which is a bit strange. If you turn on Portamento for a sound, the sound will glide between notes regardless of wheter you play legato or not. The M3's internal EDS synthesis has a "Fingered" checkbox.

BUT - there is a way to recreate this for monophonic sounds. I've demonstrated this for the standalone Radias synth in the soundset called "Radias heaven" (go to http://www.korgforums.com, press Downloads, select Radias - it's almost at the bottom of the list). However, that soundset only works for the standalone Radias, not for EXB-Radias. But I'll explain how it works.

So here's how it is done:

- Start with a new sound / init program (or any other monophonic program of your choice). Go to page P1 BASIC/DT/CTRLS, (the tab "PROGRAM BASIC") and select Mono. Select Trigger Mode: Single (important!).

- Go to page P2 OSC/PITCH, select the "OSC PITCH" tab and set Portamento to 0. Yes, zero is the value you want. We'll use another mechanism for setting the portamento time.

- Go to P5: EG/LFO/MSEQ and select the tab EG3. Set up EG3 like this: Attack:10 - Decay:0 - Sustain:127 - Release:0.

- Go back to P1 BASIC/DT/CTRLS and select the tab "VIRTUAL PATCH". For one of the patches, select EG3 as the source, PORTAMENTO as destination, and select an intensity depending on the legato portamento time you want. For example, you could select +20 as intensity. Experiment and find the number that suits your needs.

That's it. You should now have fingered portamento. The drawback is that you'll need to dedicate EG3 for this purpose, and that the sound MUST have trigger mode: Single.

The way it works is that EG3 stays at its max value of 127 (sustain) when playing legato (because of the single trigger mode), but when releasing the key, EG3 quickly goes down to 0 (release), and takes a little while to get back up again when playing new notes (attack: 10). So when releaseing the key, the portamento that is controlled by EG3 stays on 0 for a little while so that there is no portamento. But when playing legato (overlapping notes), it stays on 127 and produces portamento.

Hope this helps.

Very cunning rfos, I like that

Hi rfoshaug,

Thanks a lot for both explaining what you and xxxstudioxxx mean by fingered portamento and for providing a solution.

I listened and watched many of your Youtube compositions, and I love your music and the videos you set the music to, thanks!

Best regards,
Rob
