Logic Pro X: script gratuito per Incredible New Scripter 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.

Con l'avvento di Logic Pro X, a molti utenti Logic preghiere tanto attese sono state esaudite: arpeggiatori, ritardi MIDI, memorizers accordi, e altri effetti MIDI basato non devono più essere faticosamente creati nell'ambiente e letteralmente cablato a mano . Theyve stato efficacemente sostituito da una nuova serie di MIDI FX plug-in che si inserisce a destra in un canale Instrument spogliarsi fino a 8 per strip!

Mele team di sviluppo Logic ha fatto un lavoro superlativo creando un utilissimo suite di MIDI FX con aspetto moderno GUI.

Un chiodo nella bara ambienti?

Incluso nella collezione FX è un nuovo plug-in che elimina efficacemente il 95% della necessità di utilizzare l'ambiente per l'elaborazione MIDI. Per me, è il più emozionante plug-in della collezione, quella che ci permette di scrivere il nostro plug-in proprio personalizzato MIDI! La sua chiamata Scripter.

Il Scripter Plug-in

Script riferisce al Javascript, il linguaggio utilizzato per istruire questo plug-in come elaborare MIDI, così come quali tipi di menu interattivi, cursori, e caselle di controllo si consiglia di aggiungere al Scripters GUI (come mostrato sopra).

Il plug-in è dotato di un editor di testo integrato Javascript / linter (vedi Figura 2). Tutto molto indipendente e un bel po 'comoda funzione!

Stessa Javascript non è molto difficile da imparare. Come imparare qualsiasi linguaggio di programmazione, ha idiosincrasie che forse essere un po 'difficile da afferrare in un primo momento. Ma una volta a superare la gobba, theres quasi limite a ciò che si può fare per modificare i dati MIDI verso i vostri obiettivi finali musicali. E il linter incorporato fa un buon lavoro di segnalare errori di codifica. Non che io abbia mai fatto nessun [ahem].

Meglio di tutti, i processi che sarebbero molto tempo, se non impossibile difficile creare nell'ambiente, possono ora essere creati in casi maggio con poche righe di Javascript.

Possibilità infinite

Vuoi creare un processo in cui un ritardo MIDI emette ogni ripetizione su un canale MIDI diverso per creare ritardi multitimbrici? Oppure che dire di un setup keyswitching per dubstep oscillazione suona in cui una selezionata gamma di chiavi controlla la velocità di LFO? Idee più avanzate come strumenti algoritmici composizione, Strummers accordi e processori di legato sono tra quelle suggerite nell'introduzione allo scripting nella logica Effetti x Manuale, scaricabile a questo link.

È inoltre possibile creare plug-in mirati per migliorare ed espandere le capacità di plug-in specifici, e per questo articolo Ive ha fatto proprio questo.


Sulle stringhe complete

In circostanze normali, lo strumento Strings completa produce solo un suono di corda legato. Ma nascosto all'interno di questo strumento è una serie completa di articolazioni delle stringhe, inclusi legato, pizzicato, staccato, tremolo e due tipi di trilli! Per accedere a questi suoni, ho fatto una piccola modifica alle impostazioni del pannello frontale EXSS che permettevano messaggi MIDI generati dal mio script per scatenare queste articolazioni nascoste.

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

Impostazioni per EXS che hanno dato il mio script di un gancio per accedere articolazioni nascoste in stringhe complete


Divertente: l'EXS24 PolyArticulation Script

Questo script permette di impostare una divisione della tastiera e giocare una articolazione diversa su entrambi i lati della divisione. In alternativa, è possibile impostare il punto di split per l'alta o bassa nota estrema di giocare un singolo (e normalmente nascosto) articolazione lungo la tastiera!

Inizia il download del progetto e riprodurre l'esempio, che ho registrato dal vivo. Ascoltare come i bassi note legate suono mentre la mano destra prende atto Staccato suono, tenendo presente che entrambi i suoni sono provenienti da una singola istanza di EXS!

Ora provate questo: cambiare il suono Sotto Spalato da Legato a Tremolo e riprodurre l'esempio di ascoltare una versione più pieno di tensione. (Youll vedere cosa intendo!) Oppure selezionare pizzicato sotto la scissione e tremolo sopra.

Script, come tutti gli altri MIDI FX, sono non distruttive insert FX: sono sempre sotto tensione e intercettare dati MIDI dopo che entri nel canale dello strumento, ma prima che arrivi lo strumento plug-in stesso. Quindi, quando si registra una parte, la traccia conterrà solo le note e controller originali, proprio come nella registrazione esempio. Infatti, se si esamina la Event List nel progetto di esempio youll vedere che contiene solo le note. Durante l'esecuzione o la riproduzione, tuttavia, lo script genera dati MIDI aggiuntivi che racconta EXS che articolazioni di trigger per le note sopra e sotto la divisa.

Spero che troviate questo setup utile a delineare parti di archi, così come per stuzzicare l'appetito per il potere di 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. :)

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!

Logic Pro X is taking away the need to learn several 3rd party apps and become exhausted with learning environment tricks (stuff that I am doing daily in LP9), and it's all under one hood now. I can't wait to upgrade my operating system so I can take advantage of all these new features. Way to go Logic Pro!!!
