Where's the bottleneck with sound_capacity & SoundLimitReached?

Hi gang! First, this is an incredible library. I know it's designed for games, but I'm been using it for a real-time midi sampler instrument and it's fantastic. Tonight I decided to stress-test it a bit though, and hit a wall with SoundLimitReached that I would like to understand better.

From what I've learned, there is a sound_capacity in Capacities that can be configured, and defaults to 128. When I configure a lower number, I get a predictable SoundLimitReached error that makes sense to me. However, at 128 or higher, there's a noticeable slowdown/distortion effect before the SoundLimitReached error.

This suggests to me that I'm hitting some other kind of bottleneck in Kira's code before I hit the sound_capacity limit of 128. Any ideas where in the code I should be looking, or other settings I should be messing with (CpalBackendSettings maybe?)? I've gotten as far as I can with a source code read.
