OK here's a related thread I started: http://www.kvr-vst.com/forum/viewtopic.php?t=34461
So the thing is I've been trying to use the MIDI OUT features of Buzz to control Muzys through MIDI Yoke. It works, but the Buzz timing doesn't work well and it seems it can't be fixed.
I tried to do the same with FL Studio, which has IMHO nicely integrated midi out etc. features.
The problem is, I have similar timing problems(plus some other weird bugs).
I'm just starting to wonder what the hell is going on ... Why can't I get FL Studio play steady midi notes to control the vst instruments in Muzys?
It constantly drifts from the beat. I have a 4/4 kick + bassline sequences in FLS, controlling kick and bass sounds, respectively, in Muzys, but what I hear is not a steady beat.

Where can this timing problem be? Muzys? MIDI Yoke? my settings?

So if anyone has experience in using MIDI Yoke to control a sequencer (especially Muzys) from another and have NOT had these timing problems or know how to solve them, any help would be greatly appreciated!

Also if someone has Muzys, FLS and MIDI Yoke, I'd love if you could try what I'm trying to do and see if it works for you.

I'm getting desperate ...

You'll want to make sure you set up the 'Master Sync Output' in FL, and make sure Muzys is set to sync to it (as a slave). I'm not sure if this is possible to do or not.
Try reducing / increasing your audio buffer size and see if this affects the midi timing.

Another thing you could do is to setup MIDI OX, and set up a regular MIDI pattern in FL, and see if the timestamps for the midi events (assigned in MIDI OX) are regular.

thanks for your tips, I'll try them asap ...

(btw just to make myself clear, what I'm trying to do is not to sync two hosts together, but merely send midi notes from a host to control instruments in another)

I replied once on the other thread, but I have some new ideas (since you've changed what you want to do).

I guess I don't understand why you would want to use midi in this setup. Midi timing is notoriously unstable for syncing apps. Its fine for triggering synths, but for sync it sux. I've tried it many times in many apps -- never good enough for live work. Sure, I could use it to get an arrangement together --then combine the parts by rendering to wave and using acid to put them together in time.

My advice -- use rewire or VST for sync if at all possible (there's a reason they advertise "sample accurate host sync). Theoretically, you could use rewire or VST for sync and still send the midi notes over midi yoke if you want, though I don't know why you wouldn't just add the appropriate VSTi's in FLS and use multiple audio outs to send it to Muzys (even CMuzys supports this).

Oops, ignore the previous post. I'm an idiot.

again I'll try to clarify:

the purpose is that instead of using the Muzys sequencer to play the instruments in a Muzys project, I could play them from FL Studio.

so basically what I would have is a normal song project in Muzys, with all instruments and FX, -BUT- the actual MIDI sequences would reside in FL Studio, and the Muzys sequencer would not be used at all.

how do I *read* the 'timestamp' in midi ox?
I mean, I can see some numbers but they don't mean anything to me

MIDI OX: the timestamps are times, like on a digital watch.
The idea is that you set up a regular midi pulse in FL, and see if MIDI OX receieves it at a regular rate.
You might benefit from increasing the PPQ setting in FL if not. You narrow down the problem by seeing if it is muzys or FL that is fudging the midi.

You'll want the apps to be synced if possible to improve timing, since the events will be quantized to a degree.

I really don't understand why tou want to do what you want to do though. Surely it is easier just to set up the instruments in FL & not bother with muzys at all!
What can muzys do as a host that FL can't? I would have thought the VST/DX implementation in FL would be more mature & robust.
If you are having trouble sending midi events to a VST instrument/plugin, then use a midi out generator linked on the same port#. Or make a dashboard for it.

ok i'll try see it through ..

I compose with Muzys and I love it and will never let go of it
I just want to use FL's live mode to control my Muzys songs live. IF the MIDI timing was 100% accurate, it'd be ridiculously easy: open muzys project; export midi file; open fl project; import midi file; start jamming.
I would have FL's live mode ready for playing my Muzys songs with no hassle, with just a few clicks of export/import .MID.

I wish I could just call someone who would come to my place and fix it all up for me

You tried that BuzzVst thang ?

OK I checked with MIDI OX: the MIDI received from FL is not steady - I calculated from MIDI OX's timestamp the interval in hex between 4/4 midi notes at 140 BPM:

1AC
1AC
1AE
1AB
1AE
1AB
1AE

it should be the same all the time, right?

so how to fix it....?

what's PPQ?

I think Muzys cannot receive sync, it can only send it ... I'm not sure, I have never used sync and I have no idea how it works.

ppq is points per quarter note.
it is in the song settings dialog box in FL.

increasing the PPQ had no effect.
since this thing occurs both in Buzz and in FL, isn't it most likely a problem in either MIDI Yoke or my hardware/system ?
