Eaten (skipped) note on/note off/CC s during VST playback
Hi, I just waited for the new version to be out (5.77) before posting this (supposed) bug, to be 100% sure it wasn't already discoverd and fixed... I can say I ALWAYS noticed it since I started using Reaper and bought my licence some months ago, therefore I can't say whether it was already present since Reaper's birth or was introduced later...
In short, often (1 out of 100 times ?) but always on an apparently random basis, and without being able to reproduce the problem to date, I am experiencing missed note on events (notes won't play) or note off events (notes won't stop), or even missed CC events (for example, missed pitch bend zero CC therefore the pitch stay wrong and won't reset).
From what I can suspect, this happens somewhere in the pipeline leading to the VSTs instruments very next to it.
I'm saying that because the bug affects both live playing and playback. And when playback is affected, I can verify that the skipped midi event (note on, off, CC,...) IS ACTUALLY recorded in its place instead (in fact, by virtue of the random basis of this problem, I can try playing the indicted part again over and over but hardly I see the problem twice in the same part - at least it seems so).
So, forget that it may be caused by a faulty midi interface or master keyboard...
Oh, this perhaps is interesting... I suspected the problem could be caused maybe by a CPU overload causing Reaper to miss events but no hope: 1) THE PROBLEM AFFECTS THE SAME WAY EVEN THE RENDERING !!! Yes, I even got those missed note on/note off/CC etc even in a rendered audio !! 2) I even tried to disable transmitting the Aftertouch in case and event flooding could be the cause but I experienced the problem anyway 3) Well, the same thing happens even when live-playing (or playing back) a single VST in an empty project containing only it.
So I don't think it has anything to do with synching issues...
The only thing I could not ascertain to date is whether this bug shows up only with x86 (bridged) VST instruments or with native (x64) ones aswell... but given its random basis it is not even so easy to check, considered also that I'm still useing a lot of "old" x86 instruments (many were really good, where I can I try to use only 64 bit ones but that's not always possible sadly).... BUT I *suspect* the former... As soon as I notice the same problem with a x64 plugin I will update my bug report of course.
Is it possible that no one ever experienced the same problem ?
Well, in case it was already discussed here and I simply missed it I apologize in advance... unfortunately my workload does not allow me to spend hours searching the forum, sorry.
My config:
Reaper 5.77
Windows 7 Ultimate 64
Intel Core2 DUO
8 GB RAM
MOTU MicroLite USB Midi interface
Terratec Producer EWS Mic 2 PCI/Rack audio interface
Thanks for your support, and thanks for creating and maintaining Reaper which (despite this problem) is really the BEST DAW I could ever dream of, despite its honest and affordable price !!!
