Synthetic Legato

[Christoph Hart]

You mean something like the octave step in "Somewhere over the rainbow"? :)

[d.healey]

Not really, more for a smooth portamento on a violin, you just need to play the first and last note of the glide and it will smoothly go between them.

[d.healey]

I added an update :D same note legato is now possible.

Here's a play test from an instrument I'm working on - another woodwind library :p - I've set it up so the front end script controls the legato script, I have the sustain pedal activating the same note legato or the glide depending on if I'm playing a legato transition or not.

https://youtu.be/OUTPcFY6zKc

[MIDIculous]

This is great for acoustic and woodwind sounds. I wonder how this would sound with traditional Synth lead and synth bass sounds. Could this be tweaked to accommodate the traditional Moog type synth legato and portamento functions?

Also does it work with polyphonic material?

That's one of the things missing from Hise is a good Poly/Mono portamento glide function. That was very smart to include a formant shaper to it, so it sounds realistic.

[d.healey]

It's monophonic only although it automatically detects when a chord is played and switches to a standard sustain polyphonic mode. The glide works by playing all of the samples in between the first and last note so it retains the natural formants and only does a pitch bend between each semi-tone. I'm not sure how this would work with a synth but you can try it out and let me know :)

[d.healey]

This post is deleted!

[d.healey]

I've added an update to this script, just improving some of the code around the glide rate stuff, nothing major. I'm also posting an example project (HISE snippet) below - you'll need to add your own samples, and give them some s.mod time for the start offset to work.

Really appreciate!

[d.healey]

I've rewritten the majority of this script today to make it leaner and better. I've added support for a CC threshold note retrigger (intended for use with breath controllers).

I've removed the various mode buttons as they aren't really needed. I've added new functionality for the sustain pedal - it controls glide (as before) and can also control retrigger (as before) or detached legato (this is the new bit).

I've simplified the velocity > glide rate controls, now there is a separate button to toggle this on or off.

The legato fade time now takes into account the played interval, the speed at which the transition was played, and the velocity.

The trickiest thing with legato scripts (especially complex ones like this) is catching all the instances that can cause hanging notes. I think I've got them all but if you find such an issue please let me know how to reproduce it so I can fix it. And let me know if you find any other bugs or have suggestions to make script more efficient.

Happy New Year!!

@d-healey HI man! trying your legato script! I think it's kind of outdated, got this error:
legato2:! onNoteOn() - Line 15, column 14: Unqualified assignments are not supported anymore. Use var or const var or reg for definitions {bGVnYXRvMnxvbk5vdGVPbigpfDQzNnwxNXwxNA==}

how can I replace the deprecated assignments?

[d.healey]

@hisefilo Could you show me a snippet?

[hisefilo]

@d-healey just use the snippet you posted erlier.

Ah now I see. That snippet and the legato script that goes with it is from 2017! The latest version which I linked to was 2019. So I wouldn't rely on that snippet. Also it seems there was a bug in that snippet, the reg bendTime variable seems to be missing from on init.

[hisefilo]

@d-healey can you post the link here? Can't find it on forum search (thanks in advance:)

[d.healey]

@hisefilo It's the post before yours - https://forum.hise.audio/topic/228/synthetic-legato/13

[hisefilo]

@d-healey oh!!! Sorry. Now it's working! What a great script you've done!!

2 questions.

How can I do to dont kill notes on a chord when you play same time a legato note?
Let's say I play G chord and also note D does a legato to E. Is there a way to keep not legato notes to not be killed?

And: What's needed at my end to use part of your script? Shoul I credit you? Should I pay you? Sorry can't totally understand the license model.

[d.healey]

@hisefilo I think it would require some significant changes to prevent chord notes being killed. One way to do it is when a note is pressed you check if a chord is already playing and if it is you stash those note ids and start a fresh legato phrase. Another way would be to stash all chords by default so that as soon as a chord is played the note IDs are stored independently of legato note ids. There are probably other approaches to this problem too. The tricky part will be trying to avoid all the situations that create hanging notes.

All my none trivial scripts are licensed under the GNU GPL v3 - https://www.gnu.org/licenses/gpl-3.0.en.html - the basic gist is if you use my code in your project you must release your code under the same license.

[hisefilo]

@d-healey oh. I see. Thought a simple tweak will work but I need to do a new approach then.

I think I will split my sound source into attack and decay so I can change behavior for both independently

[d.healey]

Actually I just looked at the code again and what you're wanting is probably simpler than I thought.

I've made a modified version that stores chord notes independently in a MIDI list. There are almost certainly some hanging note type bugs but I'll leave those for you to enjoy :)
