Analogue-sequencer

I've changed the studio en rebuilded all audio and midi paths and  
cables and now I have again a weird problem with syncing the P3 to  
midiclock.

This time it is attached directly to the AMT8, where a MPC4000 feeds  
it with midiclock (on all 8 channels).

Hitting start on the MPC will start the P3, but changing the speed on  
the MPC won't change the speed on the P3 (it runs it's internally set  
tempo).

The same cable attached to the Andromeda or V-synth:

changing the speed on the MPC changes the speed of the arp from the  
Andro of V-synth.

????

Midicable is only 2 meters long...

Colin, any ideas?

That is weird...
If the P3 is started from MIDI, it immediately sets itself to respond to
incoming clock.
There's no way it can get from receiving a start message to running without
passing the code that configures external timebase.
Are you sure there isn't some weird MIDI routing going on in your AMT8 where
another clock signal is reaching P3, merged with the MPC start/stop ?
Does adjusting the tempo on P3 adjust the speed ?

Adjusting tempo on the P3 adjusts the speed indeed.

Also, connecting a midicable from the output of the MPC directly into  
the P3 gives the same result. Start/stop works, but tempochanges do  
not... :-(((

Sigh...

BTW, a memory init didn't do anything.

And I am on 3.1.005

Sounds to me like it's receiving the start / stop but NOT MIDI clock. 
Could you replace the P3 with something else on that MIDI port and 
determine whether MIDI clock is reaching there?

Yes, attaching the same cable that comes out of the MPC directly into  
the andro or v-synth controls the tempo on both of them (arps).

Boele

Shouldn't you be playing live by now? :-)

I'm pretty sure I've identified the problem.

Your MPC must be sending a CONTINUE at all times, never a START.
Receiving a START message will make P3 switch to MIDI clock, but if it has
never received a START, when it is told to CONTINUE it will still use
internal timebase.
IMO the MPC is not behaving properly - you should START at least once before
you can CONTINUE.
You can workaround this by setting the user conf option 'Start on cont'
I'll add a bit of code so that CONTINUE is always treated as START if there
has never been a START.

WOW! You're pretty smart huh???

Just checked and you are right (of course).

I would have *never* thought of that :-)))

But it would be nice indeed to have it starting always on CONTINUE  
messages.

Thanks Colin,

Boele

Boele, on the MPC there's a PLAY and a PLAY START button. Do 
both buttons give a Midi CONTINUE command? I remember it 
works fine if you use the PLAY START button on the MPC.

You're right Robert. Didn't trie that.

But still it would be nice to get it started and synced with the  
Start button too.

Yes, sure!

That was good thinking, Colin!
