[RWP] Running Hardware Midi Module

[Indigo]

Hi Jim,
I just hooked up a drum machine, with a 6 foot midi cable from the midi 
out of my sound card to its midi in, and, playing it from my midi 
keyboard there's no latency I can detect.
I also tried it hooked up directly from the midi out of my midi keyboard 
and I can't tell any difference between direct from the midi keyboard 
midi out and playing the drum sounds when the midi keyboard's output is 
going through Reaper, and the drum machine is being fed from Reaper, so, 
excess latency is not a Reaper bug here.
I left the midi output device latency offset settings at zero, since I 
couldn't detect any latency.Have you put a check in the checkbox of the 
setting in Midi Devices to use reported latency, which will allow Reaper 
to do latency compensation.
My track settings are not very different from what I'm using to record 
from soft synths, Send to Parent on, solo off, mute off, phase off, 
effects active, record armed on, record mode input, record monitor 
normal, monitor items off, automation mode touch, volume 00db, pan 
center, midi output my sound card port 00, channel all, num channels 2.
Here are the significant settings in the single track's routing dialog:
master/parent send checked; midi output to the soundcard port 00; send 
to channel 10.

Either your midi interface or the midi module you're driving must have a 
bunch of latency that Reaper is not compensating for, so Check use 
reported latency checkbox in Midi Devices.
