Implementing System Realtime msgs
Hi to all,
I have an external sequencer unit (Korg Electribe) and I am trying to get MAX to act as a master clock, so that the Electribe is running as a slave in sync to whatever material I am using in MAX.
I have the MIDI implementation chart for the electribe and it can run as a slave if set to external clock source. I am aware that I need to send it system real time messages, then start/stop the clock to make it run.
How on earth do i implement this in MAX? I can't find anyone who has a clue or has done this before!!!
Do I just set up a counter with a metronome attached, sending out continuous bangs? If so, how do I make the electribe recognise these bangs as MIDI clock messages? How do I send START/STOP messages?
PLEASE HELP!!!

Hi Alec,
I posted this a week ago:
The MIDI byte 248 belongs to the class of real time messages. This
means they are accepted at any time at high priority. The receiving
device being in external sync mode and in play mode (e.g. the
drummaschine) goes immedialely to the next 96th of the bar after
receiving the clock byte 248. This is no reference for the absolut
position just a continious time grid of 96th notes. The song position
can be transmitted by the song position pointer, see page 28 of Max
getting started pdf.
See the sync~.help file for an implementation example

Hi there
Thanks for the pointers, I have found the patch:
It seems from looking at the other thread this came from, that it is what i'm looking for...
However, I know how to save patches I make as a txt file but have no idea how to convert txt files to patches. When you refer to page 28 of the Getting Started .pdf, is this where the solution is supposed to be?
I looked through the file menu commands and found no way of converting the txt file to a max patch. How is this done?
Also, I when I type in sync~, it says "no such object" in the MAX window.
Just one more thing...
When you refer to sending MIDI byte 248 to the external sequencer, how do I send it out. Does it involve sxformat, midiout or what?
I would be very grateful for anyones assistance on this matter!!! :)
Just copy the text.....
In the filemenu in MAX choose New From Clipboard
That's it...
Sometimes if it wont work....try copying the TEXT to an empty TEXT document, and remove the space in front of each line.....
So can this only be done on a mac then? I have windows and I don't have the option "New From Clipboard" in the file menu.
Is there some way of doing it in windows, or some sort of workaround?
Thanx
New from clipboard was added in max 4.5.5 AFAIR. mac and Windows. If
you upgrade to the latest version you will have it. If not, add
max2;
as first line of the text, and
pop;
as last one. Now you will be able to open as a Max patch saves as
text. I don't necessarily exactly remember the syntax out of the top
of my head, so open an existing patch as text, and copy first and
last lines to make sure that you get it right.
Best,
Trond
Thank you to all who have tried to help - now i'll try to get on with my project!
Hope i dont have to make any more posts on this thread!!! :-)

Which version of Max are you using? If its an older one, put it into
your signature ;-)
I found more and more patches sent to the list need Max 4.5. Though most
of my patches could run on older versions, and have been made in the
first place with older versions, alone one object like patcherargs is
now in almost any patch I make. But its 4.5...
I might start a little hacking to replace some of the new objects with
abhaXions for those who are still on pre 4.5, but with patcherargs its
hard to get the same behaviour. It would only work partially.

Yes, midiout.

Thank you for the suggestions...
So, what functionality does patcherargs have?
I'm on the verge of upgrading and will do so soon cos i'm getting left behind a bit!
I'v managed to control my external sequencer using midi bytes 248, 250 and 251 (sent out of midiout) in conjunction with the tempo object. Seems to be working well, so I'm sorted for now!
Cheers
