MIDI playing live, part 2.

[kennethhsv]

This is a sequel to the original post: https://forum.cockos.com/showthread.php?t=215982

I have now gotten a sound to play on the basic VSTi (I am using ReaSynth). It is coming through the speakers instantaneously, not counting the 1.9 ms of latency I have gotten Reaper down to. Great! But now there's a new problem.

I play a note, and I hear the synth tone and a piano note. The piano tone is what I originally heard in the previous post/problem. It still lags behind the input.

Seeing as how the synth tone now responds to latency the way I wanted it to, I think this piano tone is no longer a latency issue, but it is being expressed somewhere in my chain. I've looked around, but so far I haven't found where it is coming from. So, my question is this: why do I hear two voices (synth and piano) when there is only one track, and one FX/VSTi on the track?

Thanks!
