The easiest way to get up-and-running is with the iOS app, as it has all the features available. Alternatively have a play with the version online here - just note features like splitting the audio channels or recording sound recordings aren't supported.

What platforms are supported?

pasco is a web app and iOS app currently. Here are the features and quick overview that which features work where:


Cue / Main voice splitting between headphone and speaker



Import/Export of Vocab tree



Offline support



In-App Editing



In-App Voice Recording



Adjustable font size and Colour Themes



Switch Access (1-4)



On-Screen navigation tool, Resizable and Draggable



Device requirements

So for the full-feature verison of pasco look at using it on a iOS device (iPhone, iPod Touch, iPad).

Switch interface

If you need switch scanning you will also need a compatible switch interface. Pasco is designed to work natively with switch interface boxes that support space and enter - or arrow keys. This includes: Pretorian Applicator and iSwitch, Origin Instruments Tapio, Ablenet's Blue2 switch and the Tecla. For all these switch interfaces you need to put it into a mode that supports pressing 'space' and 'enter' keys.

You can use other switch interfaces designed to work purely with Apple's own switch scanning system such as the hook+. Using these gives you the advantage of being able to use the entire device for scanning - and pasco's own features - BUT you need to be aware of how to create a switch recipe and the user having the ability of changing to this recipe when they are ready. Follow this guide if you wish to do this.

Speakers / Headphones for cue / main

If you wish to use a second speaker - we recommend right now to use a wired headphone - and just the device's own internal speaker.

Want a nice simple speaker that you can put in the headrest of a chair? Look for 'Pillow' speakers


When you first load pasco you will see a quick setup screen. It should look a little like this

Depending on which device you are using these screens may look slightly different - and depending on whether you have your screen in potrtait or landscape. But all the same options should be available.

What do all these options mean?

For a full guide on all of the configuration options read this guide. The options seen on this screen are seen below:

  • Locale Which language are you wanting the app to be setup in? Changing this will change the language of all the menu items and configuration buttons.

  • Choose an example tree "Trees" are what other communication apps call "Pagesets" or "Gridsets" or similar. We call them "Trees" in pasco because it defines how language is navigated - like an ever expanding network of branches. Here we have some example trees to get you started. Choose one to see some examples of pasco.

  • Automatic Scanning or Manual. Choose Manual if you want to try it out without a switch - or if you wish to try it with two or more switches. If you want to use it with one switch select Automatic scanning. When you do this, make sure your switch is set to Enter

  • Cue Voice is the voice to hear the auditory cue. Typically a user may hear what they can select right now with a cue (sometimes called Private voice). You can choose the voice, the rate, pitch and volume of this voice. You can try an example of the settings by pressing the Green play button

  • Main Voice is the voice that others will hear - typically the communication partner. Sometimes people amplify this using a secondary speaker. In other software this has typically been called the Public Voice.

Play/Start screen

Once you have pressed the Green "Start" button at the bottom of the quick setup screen - or you click on the small "Play" icon anywhere else in the app you should see a screen a little like this below.

The screen has two main components. The grey navigation bar at the top where you can access "Configuration", "Help" and "Edit" options, and the main language display area.

Let's now give you a quick overview of the parts of the screen.

The navigation menu

The navigation menu (see left) is a small 4-way directional navigational tool to allow a communication partner to navigate the currently loaded language tree. Pressing up - moves up in the current branch, down - moves down and left will move into the next branch - if available - or select the current item. Right will go back a level - if there is a level to go to.

Although originally designed for the communication partner we have found some clients who have a small thumb movement to be able to use this

To Resize and Move the navigational menu

Simply press and hold and then release. It can take a little while to work out the timing. When you release you are looking for a dotted line to appear around the cursor (see right above). By dragging the corners you can resize the menu - larger or smaller. Want to get it back to the default size? Hit the reset button in the middle when in this resizing mode.

To move the menu press and hold on it as above and simply drag it to somewhere you need it on-screen

The Edit button

Pressing the edit button (the small pencil icon in the grey bar at the top of the screen) gives you access to a language editor.

Want to stop someone accessing these buttons? Check out Guided Access on iOS. Its a really neat built-in way to hide elements on the screen and lock a user into a app. Read about how to set it up her

When in edit mode - select an item in your language and press the small green plus signs to add an item or the red minus sign to remove an item. Simply write your message. If you want a different cue for the item simply type it in brackets. E.g. If you wanted the main message to be hello, how are you? but the cue to be hi you could write in your box hello, how are you?(hi)

You can't view cues or advanced meta-data commands in edit mode We want to make pasco as simple to use as possible. By providing some other means to view the cue would make this messy. So right now you can just listen for the cue - and edit if you don't like what you hear

Note it can be difficult to navigate to somewhere else in your tree on iOS - so do have the Navigation menu available to you when using this mode - it really helps!

As well as adding or removing phrases you can also add or remove recorded messages on iOS. To do this - select an item and you should see a small "spanner" item at the top right of the dotted area around the word/phrase selected. Tap this and you can now press the record button to add your own recorded main or cue voice.

πŸ‘ You've successfully installed and setup pasco!

😞 Got a problem? Dang! See our troubleshooting guide.
