Clk delays out of synchro when loading patch

gomidas

Hi guys!

When I open a patch with a delay module using the Clk(Master Clock sync) function it is 'most of the times' completely out of synchro, you must stop and run the master clock again to get it synchronized as there is no Rst in those modules...(not good in a live situation)

So what should I do?...

1. use the Time value instead of the Master Clk sync?

2. use LFO, S&H with Env or any other modules to build a clocked delay with reset?

3. use external fx gear for clocked delay when needed Laughing

Does someone has experienced the same problem?

Peace to electro-music.com Very Happy

BTW this does not occur if you use the G2 master clock.
In fact I am using an external master clock, a Micro Sync actually, to synchronize my two G2 Engines...

I have found out !
It is because of my Micro Sync, I have try to load some patchs on the fly using ableton live midi clock and ....delay (Clk) works perfectly... ( Very Happy

I think the Micro Sync provides a Midi Clock but does not generate Midi Timecode (Am I right with the midi thing??).

If someone knows a bit more about midi clock and timecode...and why the Micro Sync does not work with the Clk delay (except if you reset the Micro Sync after the patch is loaded), please let me know.Thanks.

I'm not really into syncing myself, but in general people have been reporting trouble using suftware clock generators to control the G2 with, there are some other threads on the forum about this subject. Amongst others Rob did some experiments - but I'm not able to find the thread unfortunately.

I'm glad you found something that seems to work for you, the G2 seems to be a bit picky on the clock. Technically there always seems to be a trade off between being able to sync to clock changes rapidly an stability even when the incoming clock is drifting (so probably the G2 is quite good in tracking speed changes ?)

Someone had to break up the monlogue a bit :-)

I have a load of issues with clock sync, some of which may be relevant to your issues:
- Using G2 with Logic Pro 7.1 for recording:
I find that the only way to get Logic to sync properly with the G2 for recording sequencer-driven/clock synched patches is to set the number of bars of metronome count-in in Logic's recording options to none. Also, setting Logic as slave to the G2 clock does not work because you lose all control over transport functions (e.g. every time you hit run on the G2 clock, Logic goes back to the start of the song etc. - completely unworkable setup). I haven't really tried dumping patch info into Logic and trying to record a whole song, along with patch/perf changes, at once. I just record enough bars of audio for each sound and then mess with the audio track using track automation as I would any other audio track. I generally have my Logic "autoload" song template setup with 4 MIDI tracks corresponding to the 4 slots on the G2 (with each slot set to receive on a different channel i.e. 1 thru 4)
Secondly, I have switched from using a firewire MIDI interface to a USB MIDI interface - this seems to produce closer sync results for some unknown reason!
- Using G2 live synched to drummers click:
I use a G2 with my band (well, our keyboard player uses my G2!) and for all sequencer-driven/clock synched patches, our drummer controls the tempo with a drum machine that he stops and starts with a foot pedal. It sends a click to his earphones and MIDI clock to the G2. This seems to work fine so long as 1) the sequence is only a bar long (or you're just using clock synched delays etc.) - any longer and you have to be a bit organised as to where you are in the music if the drummer's click only tells him where he is in the bar!, and 2) you start the clock running AFTER the patch/performance is loaded so that the DSP recalculation doesn't throw the timing off. Again, if you want to change peformance during the song to another performance that needs clock synching, you have to work it out with the drummer so he can stop and restart the clock. Perhaps there's a better way, but I haven't found it. See this thread too - The Why Project has a neat trick for keeping devices in sync that might be useful for you...

Lastly, again maybe not relevant to your issues, but if you are having any issues with actual sequencer modules, don't forget Rob's tip for patching sequencer modules in series - connect the clock module Clock Active output to the Loop input of any serially connected sequencer modules - for some not-entirely-logical reason, this fixes some timing issues with resetting the sequence.

I've found your infos very useful. thumleft

For the usb I'm glad it works for you.But I must say my firewire digi 002 rack give me a perfect midi clock with protools 6.9 (7 is coming soon with midi realtime).

BTW I have found a trick with my MicroSync, when I load a perf on the fly (without stop & star the external master clock) and I want to sync Clk/delays; I just +/- the tempo a little bit after the patch is loaded and like this I get Clk/delays in synchro again (it is a bit tricky but....it works) !!

Anyway we are not in the same live situation, I think you did it good with your band.
