I wanted to improve the latency of the miniDexed and experimented with the SampleRate and ChunkSize in the miniDexed.ini. I noticed that the ReverbTime behaves anti-proportionally to the SampleRate.

Is it possible to change the programming so that the reverb time is independent of the sample rate or should we just document the behavior?

Why all this: I noticed an audible latency between the miniDexed and the Roland RD-300 for sounds with a short attack time. With the following values, the latency can no longer be determined and even a Raspberry Pi 2 runs stable:
SampleRate=48000 (default)
ChunkSize=128 (default 256)

With a sample rate of 96000, the latency is measurably better but the reverb time is halved.
