OK, I have this reported, so once Julian returns from vacation, he can start looking at the bug fixes, and prioritize the most bothersome ones (like this one!).

Thank you Plug and Zalush to confirm this issue. Very annoying for me.....It make the Arp function not usable in a recording.

I can confirm the issue. I use a Tempest as Master (Midi out) and Solaris as slave (midi in) with arp + hold without any other midi devices. I did the same test using a Korg Radias and an Alesis drum machine. On this test the solaris only gets time clock and the arp does its thing. Same result, the Solaris on this mode lags behind.

Now, when I sequenced the Solaris with the Tempest or Radias (midi out) to Solaris (midi in) I did not seem to hear any lag. Keep in mind this was a quick test and I did not record the audio.

In resume, when the Solaris receives time clock to drive the arp + on hold, Solaris timing is off.

Cheers,

plug

Well, as i've said above - i have the same problem with the arp. However - i don't have the same problem with the lfo's. They are perfectly in sync with cubase. Strange, isn't it?

Hi,
I'm back from Lorelei prog of night fest, nice, nice, nice.....
I saw at my return that this thread is not moving.
So i question myself : am i the only one who experienced this midi sync problem ?
Can anyvbody try this :
On your daw : metronom marking the tempo.
Midi out of your daw into midi in of the Solaris.
Choose the init sound on the Solaris.
Put your Solaris in mode : Arp and Hold.
On the midi page of the Solaris, choose : ClkSrc : Ext.
On the Arp PAge of the Solaris choose : Resolut : 1/4 and Lenght : 25 ( any small value is ok )
Start your DAW
Now play a note on the Solaris ( in time )
Wait a minute, is your Solaris Sync with your DAW ?
Thx to do that, i don't know if my unit has a problem, some midi issues here.

OK, i've tried with the Korg Kronos as Master, it's exactly the same.
Midi out of the Kronos into Midi in of the Solaris
Midi thru of the Solaris into Midi in of the Tempest
The Solaris is Slower than the tempest.

I've tried something else :
Tempest midi out into the Solaris Midi in:
This time i don't use Arp but Seq : It's exactly the same : the Solaris is slower and the tempo display is not correct.

So, i had another idea, what if i used the Solaris as Master.
on the midi page :
ClkSrc : Send
on the Arp Page
Resolut : 1/4
Midi out of Solaris into the Midi in of the tempest.
Here there are no problem, the two instrument stayed sync.

So it seems that the problem is a problem of interpretation of an external sync by the Solaris, and that if you use Midi cable or USB.

I've also tried to sync it directly with tempest ( with midi jack ).
Only two instruments :
Tempest midi out into Solaris midi in.
I've exactly the same problem.
Tomorrow i'll try with Korg Kronos, now i'm done : it's late in France.

OK, i have tried with USB, it's exactly the same.
I don't give you the audio example, because it's really similar.

I use midi jack, i can try with usb.

Well, the display of tempo fluctuating 1 number up or down is not necessarily the problem - I've seen this in other devices in the past, and it had nothing to do with the actual tracking - just something with the displayed tempo

However, obviously there is a sync problem in these audio examples. Julian & I have both tested external sync and let it run for some 10 minutes or so without problems, so I'll continue to search why.

You are using the MIDI jacks or USB?

Yes Zalush, i've also noticed this modification in the main screen, if the tempo is 120 the display changes between 119 and 120 ( never 121 for me ).

YEs John, it was not exactly on the beat, because i trig it manually and was not exactly on the time.

I Try what you say, and in this order it's the same.

I've try something else : modifying the tempo while the sequence running : the tempest react normally but the Solaris seems to have a sort of lag : it reacts but with some delay.

In your audio example, when the Solaris comes in, it already is not on the beat, so I think you need to set it to External clock [b][i]first[/i][/b], then start up/run the clock, THEN turn on the arpeggiator.

Still, one can hear a drift...but please try this first, just to check.

I've experinced the same with my unit. It also shows this on the main screen. The BPM keeps changing. If i have my DAW set to, say, 127bpm - than Solaris will some time show 127, sometime 126, or even 128. It changes up and down every second or so.
For comparison, my analog synths sync perfetly to my DAW. GRP syncs with its sequencer and lfo's spot on. So does my Vermona Perfourmer.

HI everybody,
I have this problem with my solaris :
Description : The Solaris lose progressivly the synchro midi with my other gear.
How to reproduce :
Your DAW midi out into Solaris Midi in.
Your DAW : a simple rythm playing what you want ( not the Solaris )
Launch your sequence.
Put your Solaris in mode : Arp and Hold.
On the midi page of the Solaris, choose : ClkSrc : Ext.
Modify the clock of your Daw and observe that the clock of the Solaris is following.
On the Arp PAge of the Solaris choose : Resolut : 1/4 and Lenght : 25 ( any small value is ok )
Now play a note on the Solaris ( in time ).
Observe that the speed of the Solaris seems to be smaller than the speed of your DAW.

I have a little example :
In this example, to be sure, Midi thru from the Solaris to midi in of the Korg Kronos.
You have : first : tempest
second : Korg Kronos.
third : Solaris ( the init pattern ) ( but i have the problem with all the patterns .

Notice how the Solaris is not well synchronised.
