Hi,
for the first time after I got MDrummer I ran out of processing power for a complex project. So I wanted to stem-render some tracks, inlcuding MDrummer and some Kontakt sampler stuff.
Unfortunately MDrummer was out of sync then 8(. While all the other VSTi were in sync no matter if I played them live or just their stems. MDrummer was only in sync when it played live.
Could there be some kindof bug in MDrummer reporting its latency to the host?
My system: Win XP 32, REAPER, ASIO with EMU 1616m.
Thanx
stupeT
MDrummer latency

Hi StupeT,
I;m afraid MDrummer has no latency. What is stem-render? If it is a features of something like Sonar, then I would recommend simply rendering (or bouncing for applists) the track and inserting it as a wave file.
Cheers!

stem-render = bouncing = calculate the VSTi sound + FX on the track to resulting WAV fileMeldaProduction wrote:I;m afraid MDrummer has no latency. What is stem-render?

Hmmm... how come then that there is a timing difference between the MDrummer live and the MDrummers WAV output 8(
I mean, I can manually adjust this with a delay. It is just unconvenient...
Are you really sure that MDrummer (sampler + its internal FX chain) is all latency free? All my other VSTis behave very good here in REAPER. Just one exception: GrooveAgent (I had this before MDrummer) had the same problem... Funny...
Cheers!

Are you using MIDI commands to control MDrummer?
If so, it is obviously a bug in the host (which btw?) - the host provides timing info, if it is bad, the plugin cannot be in sync. For normal VSTis it doesn't matter since they are not in sync with anything, they are just playing notes.

In this case MDrummer is playing MIDI notes (channel 10). The host is REAPER.
When MDrummer plays live in his jam or sequencing mode controlled my MIDI notes for break, Verse 1 etc... then its really tight in sync. No problem.
The thing is: if a VSTi needs say 100 samples to generate sound, then it will be 100 samples after the rest (if played live) and will be compensdated by the host. When bounced (= stem-rendered) this must be different, of course. Cause WAV comes on the fly, per sample precision, no latency.

Hmmm, I understand latency problems of course, but MDrummer has none. How different the result is? (Any latency compensated effects on the track?)

1/2 a beat off or so...
I gonna check my REAPER settings... as I said, I never had to bounce too much before. Lets see what REAPER tells me what it thinks what it shall do with MDrummer.
I'll come back to you tomorrow...

OK, here we go:MeldaProduction wrote:Hmmm, I understand latency problems of course, but MDrummer has none. How different the result is? (Any latency compensated effects on the track?)
REAPER is reporting 0 latency (compensation) for MDrummer, just like you said. I loaded the old project agagin, the bounced track still there, just muted. So I unmuted it - its still out off sync.
Now I changed my "audio preferences / ASIO / buffer settings" to very long 2048. Bounced MDrummer again. PERFECTLY in sync!
I guess here is what happened: I started this Project on my DAW in the studio. EMU converter with very low latency. Then later I loaded it on my business laptop to refine something. ECHO Indigo Converter with medium latency. Now REAPER cant find the EMU hardware and is picking the ASIO driver for the ECHO just on the fly. Seems like then its internal Latency-Compensation goes crazy. Resetting audio device properly seems to solve it.
Anyway: MDrummer was not the cause
Thanx anyway and cheers!

Ufff, thanks god 
.
You know I was suspecting something like that, because if it would be something wrong with MDrummer, it would logically be wrong during normal playback as well.
Anyway thanks for notification!
