Logic Pro X: Script gratuit pour Incredible New Scripteur MIDI FX Plug-In
Peter Schwartz on Thu, July 25th 31 comments
An unsung hero in Logic Pro X is the Scripter MIDI FX Plug-in. Using JavaScript you can create your own MIDI FX. Peter Schwartz (Mr Environment to his friends) has created a special one to download.

Avec l'avènement de Logic Pro X, plus d'un utilisateurs de Logic prières tant attendues ont été répondu: arpégiateurs, des retards MIDI, memorizers d'accords, et d'autres effets MIDI basés n'ont plus besoin d'être soigneusement créé dans l'environnement et littéralement câblé à la main . Theyve effectivement été remplacée par une nouvelle série de MIDI FX plug-ins que vous insérez droit dans un canal d'instrument dépouiller jusqu'à 8 par bande!

Logic Pro X’s new Instrument Channel Strip, shown here with four MIDI FX.

Pommes équipe de développement de Logic a fait un travail superlatif la création d'un très utile Suite MIDI FX avec l'allure moderne interfaces graphiques.

Un clou dans le cercueil des environnements?

Inclus dans la collection FX est un nouveau plug-in qui élimine efficacement 95% de la nécessité d'utiliser l'environnement pour le traitement MIDI. Pour moi, c'est le plus excitant plug-in dans la collection, celle qui nous permet d'écrire notre propre coutume plug-ins MIDI! Son appelé le scripteur.

Le scripteur Plug-in

Script réfère à Javascript, le langage utilisé pour instruire ce plug-in comment traiter MIDI, ainsi que les types de menus interactifs, les curseurs et les cases à cocher vous voudrez peut-être ajouter à la Scripters GUI (comme illustré ci-dessus).

Le plug-in est doté d'un texte JavaScript Editor / de linter intégré (voir Figure 2). Son tout très autonome et très peu le fonctionnement pratique!

Javascript elle-même n'est pas très difficile à apprendre. Comme pour l'apprentissage tout langage de programmation, il a idiosyncrasies qui peut-être être un peu difficile à saisir au premier abord. Mais une fois que vous obtenez sur la butte, theres presque aucune limite à ce que vous pouvez faire pour manipuler des données MIDI vers vos objectifs finaux musicales. Et le linter intégré fait un bon travail de pointer les erreurs de codage. Non pas que je n'ai jamais fait aucune [hum].

Le meilleur de tous, les processus qui serait extrêmement fastidieux, si elle n'est pas incroyablement difficile de créer dans l'environnement, peuvent désormais être créés dans des cas peut, avec seulement quelques lignes de JavaScript.

Des possibilités infinies

Vous voulez créer un processus par lequel un délai MIDI émet chaque répétition sur un canal MIDI différent pour créer des retards multitimbraux? Ou que diriez-vous d'une configuration keyswitches pour wobble dubstep sonne où une gamme sélectionnée de touches contrôle la vitesse du LFO? Des idées plus avancées, telles que des outils algorithmiques de composition, Strummers d'accords, et les transformateurs legato sont parmi celles qui sont proposées dans l'introduction de scripts dans la logique X Effets Manuel, téléchargeable à ce lien.

Vous pouvez également créer des plug-ins ciblées pour améliorer et étendre les capacités de plug-ins spécifiques, et pour cet article Ive fait que ça.


Sur les chaînes complètes

Dans des circonstances normales, l'instrument complet Strings seulement produit un son de cordes legato. Mais caché à l'intérieur de cet instrument est un ensemble complet d'articulations de chaînes, y compris legato, pizzicato, staccato, le trémolo et deux types de trilles! Pour accéder à ces sons, j'ai fait une petite modification aux paramètres du panneau avant EXSS qui a permis messages MIDI générés par mon script de libérer ces articulations cachées.

Settings for EXS that gave my Script a “hook” to access hidden articulations in Full Strings+

Réglages pour EXS qui ont donné mon script d'un crochet pour accéder articulations cachées dans les chaînes complètes


BONUS: l'EXS24 PolyArticulation Script

Ce script vous permet de configurer un partage du clavier et de jouer une articulation différente de chaque côté de la scission. Ou, vous pouvez définir le point de partage à une haute ou basse noter extrême pour jouer une seule articulation (et normalement cachée) sur le clavier!

Commencez par télécharger le projet et lire l'exemple, que j'ai enregistrée en direct. Écoutez comment la basse note Legato sonore tandis que la main droite Staccato note sonore, en gardant à l'esprit que les sons proviennent d'une seule instance de EXS!

Maintenant, essayez ceci: changer le son ci-dessous Fractionner de Legato à Tremolo et lire l'exemple d'entendre une version plus tension-rempli. (Vous aurez voyez ce que je veux dire!) Ou sélectionnez pizzicato ci-dessous la répartition et le trémolo ci-dessus.

Scripts, comme tous les autres MIDI FX, sont non-destructive insert FX: ils sont toujours sous tension et interceptent les données MIDI après son entrée dans le canal de l'instrument, mais avant qu'il arrive l'instrument plug-in lui-même. Ainsi, lorsque vous enregistrez une part, la piste ne contiendra que vos notes et de contrôleurs originaux, comme dans l'exemple enregistrement. En fait, si vous examinez la liste des événements dans le projet exemple youll voir qu'il ne contient que des notes. Pendant l'exécution ou la lecture, cependant, le script génère des données MIDI supplémentaires qui raconte EXS qui articulations pour déclencher des notes au-dessus et en dessous de la scission.

J'espère que vous trouverez cette configuration utile pour dresser parties de cordes, ainsi que pour aiguiser votre appétit pour la puissance de Scripting!

    Hello I was looking to access Meta data to handle score accidents Did you find the trick ? Best Cyril

    It does not seem possible to generate Meta or Fader events from a script. Even if it was possible, you can't use Scripts to process data before it enters Logic (at the Sequencer Input object in the Environment), and that is the ONLY place where Meta events can be passed into Logic for the purpose of recording them on a track. Since you can't insert a Script in any object in the Environment, and since Scripts can't generate Meta events anyway, it's just not possible. Now, you can still attempt to use Environment objects to generate Meta events (for score symbols or whatever) and feed them into the Sequencer Input. However, it will be an exercise in futility. Or, I should say, in Logic 9 and prior it was futile, because something in the code prevented that from working. I haven't tried it in Logic X tho. If I get a chance I will and post back here if I get a positive result.

    Hello Sky Thanks for your answer. I do not want to generate meta, but read Meta that are in the score to send changes of articulation in Vienna Symphonic Library first, I may also extend it to Play and ....... It will look like this : If Meta = "Legato" then send "C0" If Meta = "Staccato" then send "C#0 if Meta = "pppp" then send "ctrl 7 with value 20" if Meta = "ppp" then send "ctrl 7 with value 30" if Meta = "pp" then send "ctrl 7 with value 40" if Meta = "p" then send "ctrl 7 with value 50" if Meta = "f" then send "ctrl 7 with value "64" ....... So how can you read Meta ? Do you have the list of the Meta with there code ? Thanks in advance Best Cyril

    Scripts cannot read Meta Events, so you're out of luck there. I believe it's possible to do this directly in the environment. However, I'd like to suggest that the idea of associating dynamic markings with specific values sounds good in theory but isn't a practical approach. First, just adjusting the volume (CC#7) won't give your parts a natural sound. Second, if you had a sudden (subito) jump from "p" to "f" and any of the "p" notes overlapped even slightly into the "f" part, the transition is going to sound unnatural. While riding volume alone won't give you an very natural sound, it's better than nothing, and in that case I'd suggest riding automation on your parts to match the dynamics you want. If you want natural dynamics from Vienna stuff, you have to use a combination of riding the values of velocity xfade, the filter, and volume. But that's a whole other subject. :)

    Hi Ski Thanks for your mail > Scripts cannot read Meta Events, so you're out of luck there. So this Scripter IS A PIECE OF S..... I AM SO DISAPPOINTED, IF I HAVE KNOW THAT I WILL NOT HAVE BUY LOGIC X I AM FEDUP OF LOGIC DEVELOPMENT TEAM THAT DOES NOT DEVELOP WHAT USERS NEED AND DEVELOPING THINGS WE DONT NEED WE ARE Thousands USERS USING VSL, QLSO ... and that are needing to drive articulation changes from score

    Cyril is right... the Scriptor is Totally Useless.... First i thought... yeah great ... then i began to script articulation switches.... everything is just recordable into the Automation ... I dont need something like this ... i need the midi data or the Meta Events, recorded into the file... not into the Automation....

    Hi, I am still downloading Logic X on a very slow connection so as of yet I cannot tell for myself but I have a question: Can I, for example, make a script that SOMETIMES plays one chord and sometimes another given a single note AND actually 'use' that data? From the article: Scripts, like all other MIDI FX, are non-destructive insert FX: they are always “live” and intercept MIDI data after it enters the instrument channel but before it arrives the instrument plug-in itself. So when you record a part, the track will contain only your original notes and controllers, just as in the example recording. In fact, if you examine the Event List in the example project you’ll see that it only contains notes. During performance or playback, however, the Script generates additional MIDI data that tells EXS which articulations to trigger for notes above and below the split. My question is: Can I record or save somehow the additional MIDI data for later use? eg editing? I hope this makes sense

    Hi Dave, what you said totally makes sense, and you've got it exactly right. Scripting and other MIDI FX are "non-destructive" and therefore only process MIDI data entering the software instrument's channel strip. What you'll see in a region is the data as it originally came into the software instrument's channel strip. But within the channel strip, the MIDI is processed on its way to the plugin instrument. Recording the output of the process (i.e., the output of the Script) is proving problematic. In fact, I've been working hard trying to find a foolproof way to record the output of a Script without any kind of "gotchas". I think I'm making progress, so "please stand by". :)

    You do that with "chord memorizer " You can add "transformers" that will select different "chord memorizer " depending of either a CC change or a specific note range Have one in Minor, another one in Major, another in Major 7 ........ If you want to record the result you send the end of the chain to another midi instrument and record it

    Just read your reply. I don't believe your idea will work, because you can't record the output of an instrument. So if you cabled your environment process to another MIDI instrument, it would play that instrument but it wouldn't be recorded.

    Hi Peter, Thanks for the awesome little script, however for some reason I cannot get it to work properly. I am literally copying and pasting the script from the file in your article into the scripter in a new project in Logic Pro x (I have even saved it as a preset in the script window). Basically when I run the script, the GUI/front end loads up the two boxes to select the play methods (legato, pizzicato etc) and the Split note (e.g. C3) but it doesnt seem to actually split the keyboard - or change the sound according to the play methods I select. When I looked in the script, it says the following Pluginparemeter[0] missing unit Pluginparemeter[3] missing unit Which I assume is the above split and below split paremeters not working properly. I am a bit of a code newb so not sure how, in the process of my copy and paste, I am getting this wrong haha Any info appreciated. Thanks in advance Chris P.S do you know of anywhere we can get more scripts like this - been looking around and not much available.

    Hi Chris, sorry you're having trouble with it. The messages you see about the missing unit in the Plugin Parameter are benign. However, I've gone and changed the code so that it no longer reports that message. It's working 100% as far as I can tell at 3:30 in the morning. I'm going to post a new message after this one with the new code. You can copy and paste it into the Scripter. Then, hit "Run Script". It should work 100% fine. If not, post back. Regarding other Scripts, it's early days yet. Presently there are problems associated with having too many scripts in a project which apparently Apple is aware of. But I'm pressing on all the same, and have a variety of plugins that I'm developing to do all kinds of neat stuff.

    Thanks for this. I tried the new code and alas still no love. Perhaps its something to do with the setup of my instrumentation - I am going into EXS24 > Orchestral > Strings > FullStings+ right? I have tried Stereo and Multi output versions - but still get the same result. Basically, the scripter says it works (so no more missing plugins) but seems to be sticking to the default sound that loads up when the sampleter starts (i.e. doesnt change when I change the selections in the scripter) not sure how the flipping flip I am going wrong with this... Cheers for your help Chris

    Gonna suggest that you download the project from the link above (it's been updated with the new code) and save the Channel Strip as a new Channel Strip Setting. Note that the script won't work unless Full Strings+ is modified as shown in the picture above, so the easiest move would be to save this as a Channel Strip Setting. No need to copy and paste code to make it work. Also, just for the record (wink) there weren't any missing plugins. The original code worked fine. I just didn't specify a few non-critical parameters that resulted in what appeared to be error messages but had no bearing on how well the script worked.

    Boom. That did it. Nice one, thanks. Is this script limited to just FullStrings+ in EXS or are there other ways it can be tweaked? Awesome job though, sounds great with the two 'multis' at the same time. Chris

    Hi Chris, Glad it's working for you. Yes, this script can be used with any EXS-24 instrument that has multiple samples (articulations) where each one is programmed within the EXS instrument itself to have a unique Articulation ID. Critical to the operation is setting the EXS's modulation matrix as shown above. Full Strings+ has 6 articulations, and the value of 25 you see in the code specifically addresses having six Articulation ID's. If an instrument had a greater or lesser number of articulations, that value would have to be adjusted (and so would the labels in the menus).

    I've followed Ski's method laid out in another forum thread to allow for more expressive playing of stock EXS strings using the modwheel (thanks!). But does anyone know if you can program a script that approximates this with non-Logic EXS instruments like Garritan or Sonatina Symphonic Orchestra? Some of these free or cheap libraries could work much better I feel if we could impose the same filter cutoff and volume tweaks using the mod wheel for better expression. Thanks in advance!

    Thanks Peter for these insights. I have to say though, it would be nice to have a MacProVideo tutorial about the Logic Scripter. For someone who comes from the musicians side it's quite difficult to get into coding JS/Midi... But this looks really promising I think. Enormous potential this scripture has!
