MIDI Clock issues

MIDI Clock issues

2002-03-06 by erik_magrini@Baxter.com

Actually the electribe clock is running slower.  If the Electribe says it 
is running at 120, it's really running @ 119.79. 

>>>How did you measure this?  Just curious as I need to measure some MIDI 
clock info (for Red Sound), but I'm not too sure about the best way to do 
it.  Is there anyway to record MIDI Clock info linearly, so you dcould see 
any fluctuations over time? <<<

The easiest way is to make a sample that's exactly one measure long trim the dead space, then loop that and compare it to the original till they sync without drifting. (Using sound forge) You can then calculate tempo by going to special, edit tempo... and setting the number of beats. If you have a sampler you can also do the same thing with that. It's based on #samples/#beats/sample rate or something like that. You can get calculators like:
Alternately you can just take it off of midi, get an accurate metronome and see who gets faster or slower. The computer tends to be dead on (Logic, Cubase, Fruityloops, Hammerhead, etc), 120.0=120.0. I've left my MC505 locked up with my computer for over an hour before with no midi and no drift, locked dead on.
Are you working with Red Sound or just seeing if their products work?

Working with them to try and troubleshoot why my XL-7 locks up and/or 
drifts randomly when synced to the Micro Sync.  I got the XL-7 to 
compliment my DJ sets, and lately I've been having too many sync issues 
with it to use it that way (at least at my bigger gigs).  So far it looks 
like it's an XL-7 issue, the ER-1 syncs up fine, never locks either. :(

I have the federation bpm pro, it does a fine job with Midi clock, although every once in a while it will hiccup and throw everything off by a beat. I'm not using it with the XL7 tho, it definately uses subtempo/has it's own clock speed.

The XL-7 cannot sync to external MIDI clock. I spoke
with Emu support and it's a known issue (how could it
not be?) and supposed to be getting fixed with the
next OS.

You can't use this box in a live situation, unless all
you want to do is play back one pattern (and the box
must be MIDI clock master.)

It's such a great synth/seq -- too bad it has this
terrible flaw.

Hello all! I'm using the MP-7 with OS 1.18 and I have no problems 
syncing it to none of my devices. Ensure that if you are going to 
have the XL/MP-7 as the slave that the cables are connected correctly 
and then go to the CONTROLLERS button and scroll all the way to the 
end and make sure to set the base tempo to external (EXT). This will 
immediately change the tempo to whatever tempo the master controller 
is set at and if using the XL/MP-7 as the master ensure that this is 
off and the slave device is setup correct. This should help you guys.

RE: [xl7] Re: MIDI Clock issues

2002-03-14 by Andre Lewis

Wooohoo I have watched weird clock drifting from the midi clock readouts:  With
clock set to external, from my MC505 the tempo is 142.  I only have the 505
sending clock, no other midi transmitted.  When I stop the 505 the readout on
the XL-7 is 142 on the Base tempo screen, 141 on the LED display!!!!  When I hit
start, the ext. tempo reads 143, led reads 142!!  Then if I hit stop and then
start the led reads 139, EXT reads 140, then slowly comes back to 141 sometimes
142... ????  This is all very exciting!
	Oddly the 505 is one of the few pieces of gear I have that actually plays back
at the same exact tempo as my computer unsync'd (No midi cable) with no drift.
Actually all my roland gear plays back at the same tempo unsynced, even the
sampler if I make sure it says it's tempo in samples is exactly right. I don't
think it specifically matches my soundcards clocks, since I use multiple sound
cards, and have switched like five times.  I've also never had problems with my
other gear locking to it either even notoriously badly clocked gear.

Actually it looks like it's pulling a DJ style affair, since it can't lock to
subtempo's it's speeding up then slowing down to "Catch up" to the incoming
clock.  A push pull affair.  That's what my Federation BPM does, makes it
unuseable to lock beats with a record because it's not subtle.  I'm sure
actually that Emu is all over this, so I'll let em go back to work...

How bad is the actual drift you are >;hearing
Midi clock sends a pulse, not a specific BPM number, and jitter is normal (though not desirable, of course). If a slaved midi unit thinks that the clock has changed from 140.50 to 140.51 it will change the number displayed to 141. I've seen softsynths do this too.

Right. It's noticeable, it'll drop to 139 from the actual 142, short midi cable directly to the Emu. At the very least I think it causes it to throw the songs out of alignment. It's very noticeable. But they are also aware of the problem, so I think it should get fixed fairly soon.

I've tried numerous cables and always set it to EXT, still get issues with 
syncing.  It IS a known bug, glad it works for you though!
