Before we took a detailed look at the Tool Slider in Quincy - a very central and important topic. Also very central and important are documents. Quincy is a document-based application and that is a good thing, because you can save, edit, share and collect your compositions.
This seems a good place to mention a somewhat unusual fact about Quincy's windows. While they can be resized, this is only possible using the corners of the document window. The reason for this is that Quincy has to maitain a square aspect of its world - the rendering view. Therefore just making the window taller or wider is not possible. This is also the reason why Quincy doesn't run in full-screen mode. It would just occupy a mid scetion of the screen while leaving the rest empty. Minimizing and maximizing Quincy's windows however works as expected.
Since Quincy is also available for iOS (https://itunes.com/apps/quincy) you might want to move some of your compositions to your iPhone or iPad. To this make sure you have Quincy installed on your device. Then launch iTunes on your Mac, select the device and click the Apps category in the list to the left of the iTunes window. Then under File Sharing in the center column select Quincy. The list on the right side now shows all documents you have available for sharing. You can drag your compositions right on top of that list and you are pretty much done with the Mac aspect of file sharing between your devices. The document section of your Quincy for iOS documentation show the remaining few steps that are needed to get your composition imported to your iOS device (https://www.rogame.com/d/ios/quincy/qcy04_documents.html).
Quincy comes with a whole bunch of sample documents to give you a bit of an idea as to what is possible. These templates can be found via the File/Sample Documents menu item. To use these documents as the basis for your own compositions use "Save as..." to create a copy of a particular document first. Changes to the sample documents themselves cannot be persisted.
So far you have seen compositions in action, learned about Life worlds, the Tool Slider, the 3 application modes Play - Edit - Draw and now you know pretty much all there is to know about documents in Quincy. Most of the latter should be fairly familiar territory - things you have seen in other applications, but anyway, that's pretty good. Next we are going to take a look at the various tabs in the tab view. And we'll start with Modules where you select your instruments and more to generate sound.
