CP 1919

CP 1919 is the latest and most experimental audio app from The Strange Agency.


A physics-based fluid simulation drives an additive synthesizer, controlling a fat stack of up to 24 oscillators. The multitouch interface lets you control the fluid with your fingers, exciting the oscillators like strings on a liquid harp.

Various settings alter the fluid’s behavior as well as the resulting sound. Coax the fluid into a gentle motion, or crank the parameters for instant sonic madness.

Furthermore, a large ribbon controller lets you detune the oscillators, creating rich, sonorous harmonies or the thickest dissonant cacophony. Meanwhile two independent LFO’s allow automated control of both oscillator spread and aggregate pitch.

Play CP 1919 as a drone by strumming the fluid with one hand while tapping the ribbon with the other or use the on-screen keyboard to play it like a more traditional device. The HOLD control lets you leave the sound on or make it keyboard-activated. Hold down ZERO to force the fluid to subside, or turn up the DAMPEN slider to kill its momentum. As always, experiment!

    cp 1919 doesn’t make any sound ?? should i reinstall ??

    • lucas says:

      A reinstall shouldn’t make a difference. What OS are you using? In OS 4.x try quitting the app completely by holding down its icon in the task switcher and then clicking the X that appears. Upon restart you should get sound by touching anywhere the wave area.

    Hello!

    Any chance on this app, and Curtis having midi capabilities?

    Great apps by the way!

    Hi! I’m a composer, and I’ve been using the CP 1919 for about a month now. I love this thing! I’m currently writing a piece for oboe, piano, and CP 1919 which will be premiered in Italy this July, and I’m also going to be giving a short lecture about it. Is there a way that we could speak more in depth about the mechanics behind the app and how it works so that I can compare my studies on it with you? If you want to contact me through email, that’d be great. Thanks!

    when oh when will you make this for ipod touch, or have you? Luv Curtis and yr overall esprit…

    Best,

      We’re evaluating porting this to iPod and iPhone. It’s not really clear if the loss of screen space and processing power will still yield a useful app. Stay tuned!

    Enjoying CP 1919. One thing that sticks out is the inability on my new iPad2 to have all parts of the interface rotate. I like to use my folding cover as a stand when playing CP1919 but almost everything is upside down… a few things like the sliders rotate, but not the fluid etc.

    Thanks for a great program

      This design was our clever way of keeping the interface stable but readable from various angles. Sometimes it’s better to avoid clever. The idea has indeed proven unpopular, particularly since it’s opposite of the Apple case orientation, so it will be changing in a future update.

    Just purchased CP 1919; your recorded files seem to be a proprietary format only readable by CP 1919. I want to be able to further manipulate the audio in the DAW on my Mac. Is there any way to export audio files, or is audio only available via the headphone out on the iPad?

  7. Hello Strange Agency Team,

    I am a big fan of your apps …
    I love noise apps …
    Would you mind telling me what CP 1919 means ? where does the name come from ?

    I love the drone sound made by CP1919…
    I dream one day you make a CP1919 version for iphone …so that I can hear it and use it everywhere…

    Take good care,
    Serge

      Thanks for the love! As some have noted, the name refers to Peter Saville’s famous album cover for Joy Division’s Unknown Pleasures. Do a little googling and you’ll see why :)
      The math of the fluid simulation makes iPhones cry. Maybe we’ll make a mini version…

    mi cp1919 dejo de sonar en Ipad2

  9. chairman says:

    Record – yes, no problem.
    Save – sure, no problem.
    Now what?
    Where are the files?
    How do I play them?

    • lucas says:

      They are saved to the app’s Documents directory. You can access them via iTunes. With the next update of CP 1919 you will be able to copy the recordings into other apps or upload them to your Dropbox.

    hey there,
    love it, as usual, but all your apps disturb the running audio for a few seconds while they load, i tried cp1919, donat and curtis they all do that
    “lala”

  11. Lala says:

    a way to give the wave a kick with y axis rotation of the ipad would be cool

  12. Jo says:

    Any news on an iPhone version?

    As excited as I was for the new update I was really bummed when I saw that you guys changed the appearance of the app from wha tI thought was an amazing look to something that is (in my opinion) decidedly more pedestrian and “normal” looking.

    Is there any chance that I’ll be able to restore the look of the app to the older (and much much better looking) aesthetics? Please? Pretty please?!?

    • lucas says:

      Absolutely no chance! :)
      We knew some people would hate the new graphics and some people would love them. If this was a functionality issue we might offer two modes, as with the orientation switch. However, we don’t see any real value in allowing skin swapping.

      To be honest, I quite liked the minimal design of the original, and it was intended to match the Joy Division graphics to which the app tips its hat. However, it seems consumers want apps that look like real things. Or is this just a misconception on the part of the app developers? Why do so many awesome apps look like they are made out of 1970′s hardware?

        The platform does an impressive job of simulating all those old boxes, pedals, knobs, and dials. But chalk my vote up for interfaces that creatively use multitouch, XY, and drawing elements to create completely imaginary things. Keep up the great work!

Say something nice
