The square wave oscillator is silent in the modular synth component

Reproduced 3/3 times. Issue does not occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed Regression.

Note that Sound can be heard when Osc types are set to anything else besides Square, or when only one Osc Index is set.

1. Create a new Actor Blueprint
2. In the Components panel, add a ModularSynth component
3. In the event graph, wire the blueprint as followed:
   1. Event BeginPlay > Set Osc Type > Set Osc Type > Note On
   2. Get Modular Synth > [All Target Inputs]
   3. Have first Osc Index set to 0, and the other to 1. Change both Osc Types to Square
   4. In Note On, change Note to 60 and Velocity to 100
4. Add Actor Blueprint to level
5. PIE

Actual Result: No Sound can be heard

Expected Result: A Sound should be heard
