PlayStation DualSense™ Controller
Haptic Composer solves the testing problem by including an audio player along the Interhaptics engine for playing synchronously the haptics and audio track on the peripheral of choice.
You can control the haptic effect with the Play and Stop buttons by choosing as Player the PC option (not Mobile) and the effect will play from either the start or the cursor to the end of the track. Haptic Composer includes latency controls and audio volume controls to compensate for some system-specific behaviors. The player can be used to test haptics with or without an audio track.

PlayStation DualSense™ adaptive triggers
Haptic Composer supports the PlayStation DualSense™ adaptive triggers and they will render the stiffness perception. This can be easily made by creating a haptic effect and adding Stiffness from the Perceptions panel situated on the right side.
Designing and testing for adaptive triggers requires defining your force profile curve and pressing SET LEFT and/or SET RIGHT on the top right menu.
You can quickly iterate the effect you want to achieve by updating the effect directly on the device and comparing left and right experiences.
