Expand the Flowfal Tutorials folder that will be visible when you select Flowfal from the Places list on the left hand side.

Open the 04_Attitude_Inputs.als Ableton Set and a set with a single track will appear.

Press the Play button top centre to start the track running. An arpeggiated clip will start playing.

Start the Flowfal app on your Apple or Android phone and it should find the FlowfalMaster running inside this set and connect to it.

Once connected, the Flowfal App will display a choice of No Sound or Attitude Demo as the channels you can select. Select the Attitude Demo option.

Rolling the phone will now control the cut-off frequency of the Sampler.

For this tutorial we are going to be focussing on the Attitude inputs to the FlowfalMap plugin, but the same Attitude input section is present on all the Flowfal plugins that process movement signals.

Note that as you roll your phone or watch the Angle display will show what angle is being received. This display is very useful for working out what range of angle movements you want to select.

Initially the movement input has been set to Roll, but if you select Pitch from the drop down list then tipping the phone up and down changes the cut-off frequency. Selecting Yaw from this list mean the input responds to the direction the phone is facing (North, West etc).

The Roll and Yaw inputs range from -180 degrees to +180 degrees. You may not want to use movements that require the phone to be turned around to that extent. Press the Wrap 180 button to enable it and you will see that the range for the Roll or Yaw signals will be wrapped to -90 and +90 degrees. This also has the effect of getting rid of the sudden transition from +180 to -180 degrees in these signals.

Note that the Pitch signal is always constrained to between -90 and +90 degrees.

The Filter setting allows you to control how much filtering is applied to the input signal. The higher the value the smoother the signal changes will be, but in addition the longer it will take for movement to register an output signal. Try setting the Filter to 10ms to see how much faster it is at responding, but also how much noisier the input signal is.

The final output signal of this Attitude section is shown at the bottom of the control in an orange guage.

Set the input back to Roll and switch the Wrap 180 button off.

Currently the Start angle is set to 0 degrees and the End to 90 degrees. This means that the output signal only changes when it is between these two values.

So if we change the Start angle to be -90 degrees, the Frequency control will be at its minimum when the phone is rotated 90 degrees anti-clockwise from flat, and at its maximum when the phone is rotated 90 degrees clockwise from flat.

The Offset setting allows you to add or take away a set rotation, in degrees, from the input signal.
