The in-app sounds of the Motion Synth App are designed to respond expressively to motion or orientation input.

The easiest way to use these in-app sounds is to watch the in-app tutorial videos and then try out the Factory Presets that include in-app sounds.

You can also modify these Factory Presets and then save copies of them as new custom presets, as explained here.

These in-app sounds can be selected within the Notes Tab (Main Menu), where you can also alter their scale, octave, and reverb properties.

However, if you wish to configure these sounds at a deeper level, the information below may assist you.

If the 'BLANK' preset is selected in the Presets Tab (Main Menu), no modules will be loaded in the Motion Tab (Main Menu) and In-App Sounds will be switched off in the Notes Tab (Main Menu).

Starting with the BLANK preset described above, navigate to the Notes Tab (Main Menu).

Find the In-App Sounds section of the Notes Tab and switch on In-App Audio. Then select an instrument from the Instrument list.

Now navigate to the Key Screen and try touching any key. This will trigger a note to sound at full volume, with no ongoing motion control of its sound parameters.

Now navigate to the Motion Tab (Main Menu). Because we started with the blank state described above, there should be no modules present within the Motion Tab.

Now add a Send Continuous Controller (CC) MIDI Messages module.

This module has a default 'MIDI Channel' value of 1 and a default 'MIDI Controller Number' of 7. These defaults are the values required for this module to control the volume of the selected In-App Instrument.

For most of the instruments, an additional sound quality will also be controlled by the module configured in the above way (sending MIDI CC messages on MIDI Channel 1 & MIDI Controller number 7), as listed in the table below:

The Send Continuous Controller (CC) MIDI Messages module defaults to using Up-Down or Left-Right Motion as the Input (Motion or Orientation).

All of the Factory Presets that incorporate In-App Sounds use Up-Down or Left-Right Motion as the Input for controlling the sound parameters in the table above.

However, you can use any motion or orientation as the Input to this module, which will thereby control the volume and other sound qualities of the instruments as listed above.

Experiment with changing the motion or orientation input to this module. For example, try selecting Left-Right Orientation as the Input (Motion or Orientation).

In addition to using Up-Down or Left-Right Motion to control volume and timbre, the Orchestra instrument also uses Forearm Rotation to mix and crossfade its component sounds.

If you select Factory Preset 3 you will notice that there are additional Send Continuous Controller (CC) MIDI Messages modules within the Motion Tab that are using Forearm Rotation to mix and crossfade the component sounds listed here:

Note that the Send Continuous Controller (CC) MIDI Messages modules using the MIDI Channel numbers above are all using a MIDI Controller Number value of 7.
