Expression maps Tremolo trills etc

Hi everyone,

Just want to check something :
The options for trills and tremolo for using a sample instead of Dorico’s own simulation do kick in only if you assign Base switches for these and won’t work with Complementary switches, right?
If so, it will be great to make it possible, since it can easily save thousand of lines when programming maps.

I haven’t tried it, but I don’t think there’s any technical reason why it won’t work with add-on switches.

Hi Paul,
Would it be possible to check it out? In my maps, tremolos and trills won’t trigger my soundbanks when mapped to an add-on switch, but it works fine with a base switch.

Could you attach a minimal example that shows the problem, along with the MIDI notes or CCs that are needed to trigger a trill/tremolo in your library?

Be aware that if you have a trill, then the switches for the base switch and the addon switch are played

Hi Paul,
Here’s an example. I’m using VSL, both VI and Synchron.

Natural and Tremolo are in two different slots at KS C0. CC 20 at 1 should trigger Natural and CC 20 at 127, tremolo.

In the map, I’ve put two switches to activate tremolo:

  1. ADD-ON switch that only sends CC 20 to 127 (126);
  2. BASE switch that specifies the KS and CC 20 to 127.

If you activate the ADD-ON switch, it does send CC 20 to 127 and plays the tremolo patch but with Dorico’s tremolo simulation on top of it.
If you activate the BASE switch, tremolo patch is activated without Dorico’s simulation.

I’ve looked at this project, and I think the problem is that this isn’t a case that add-on switches were designed for. The intention for add-on switches is for plugins that use different CCs to control different articulations. For example, CC14 controls con sord on/off, CC15 controls vibrato on/off, CC16 controls marcato attack, CC17 controls arco/pizz. Before we had add-on techniques, you would have to define 16 different entries in the expression map for every combination of con sord/vibrato/marco/pizz . Because these CCs are independent, we can create them as add-ons, and Dorico will generate the correct values for CC14-CC17.

In your case, you have CC20 in the base and in the add-on. When the tremolo is played back, you get both of the CCs at the same position, and so only one of them will be used by the plugin (and I don’t think it’s defined which one will ‘win’).

So if you want to give a different value of a CC that is used in the base switch then you can’t use that CC in an add-on switch.

Hi Paul,
Yes I know for which purpose were the add-ons created for and use them as planned with other libraries. But what I’m trying to do with VSL is based on the same idea. The thing is that it actually works fine except for the articulations that trigger a built-in behavior by Dorico. I also use a similar CC setup to access or cross-fade from ord. to ponticello or tasto, or from vib. to non vib. with no problem at all.

In the case I have submitted to you, the cc20 to 127 command of the tremolo add-on switch does overrule the cc20 to 0 command of the natural base switch and trigger the tremolo sound. The problem is with the build-in tremolo simulation that Dorico generates. It only complies with the command to '“stop the simulation when an external sound is assigned” when it’s done through a base switch. So when the add-on tremolo switch is activated, I get my tremolo sound with Dorico’s simulation.

So to get my tremolo sounds, my two options are:

  1. use base switches, meaning I have to program every possible combinations where a tremolo is possible, which amounts to hundreds of entries;
  2. use a fake technique that will not trigger Dorico’s build-in simulation. The problem with this comes from the fact that tremolos can only be excluded from playback by deactivating the notes they’re attached to. So to trigger a tremolo sound, I have to create a second staff, enter the notes with the fake technique, hide the extra staff… well, a pain.

That could all be avoided if Dorico’s built-in simulations (for tremolos and also for trills, harmonics…) could react to add-on switches the same way they react to base switches or at least, if there was a local on/off toggle to override them. I have no idea if it’s a big programming job for the team, but it sure would be appreciated.

Ok, I understand now. Firstly I would advise some caution when using base + addon with the same CC, as I found that both of the CC values were inserted in the stream, and there is currently no guarantee of how these are ordered. So it may work in some cases, but randomly not work in others. I will make a note in our database of the issue to suppress the generated tremolo notes when using an add-on.

You’ll forgive me for jumping in here, but can I ask Paul if Add-ons always need an … “Add-off”?

E.g. if I have Legato on CC68, do I need to create a “Non-Legato” with CC68=0…? Or does the Add-on switch itself off when the condition ends? I’m getting variable results with different techniques/CCs.

The add-on switch has an ‘on’ action and and ‘off’ action, so you’ll need to add the CC68=0 to the off action.

Hi Paul,
Yes, I think it would be a good idea to have an easy way to override any simulation build-in Dorico. I think all the libraries I know actually need both modes to work properly. For example, you might have a tremolo or trill sample for normal playing, both none for things like on the bridge or muted… So it would be great to be able to decide when to use the samples or Dorico’s simulations, as it would reduce the number of necessary fake techniques.
I’m very happily surprise to read that off actions work. Is it new from 3,5? Because I never got any results from them. If they do work as expected it would indeed remove all reasons to set contradictory cc data in base and add-on switches. I’ll check it out later this week.
Thanks for your answers,

We do want to have more control over generated playback techniques in the future, but I’m not sure yet how this would work.
I haven’t specifically tried the case with off actions and add-on switches, but try it and let me know if it works.

Hi Paul, note off actions work with CC but not with KS in both base and add-ons. I didn’t test PC
