multiple drum sequencers

Is there an easy way to stack up drum sequencers such that one runs through its steps, moves on to the next one which runs through its steps, which moves on to the next one...etc. until at the end of it all the first one is reset and run again so the whole affair is in a loop? I basically need a drum sequencer of more than sixteen steps. I have some ideas of how to get it to work but have the free version of the software so I cannot write more than one drum to my PLC (DL06)to test. If this is something that is easy to do I will go ahead and buy the pass key as I will need this function a lot in the future.

    I don't know about multiple drum sequence but you can set up a timer or counter and use comparative contacts and your limit is the number of outputs that you have.

    Just running off the top of my head, but the last step of a drum could be a 1/10s pulse of C10, then the next rung following the drum could be

    STRPD C10

    SET C20

    Then use C20 to run your second drum. At the end of that, use the same method with C11 and so on. Then after the last drum, reset all the C bits you set.

    Thoughts?

    gilsdorf,

    You can "Roll your own " and make single huge drum that could have 1000+ sequences / images. This can be done in less then 100 words.

    Basicly you setup your drum images in user memory (like say V1200-V7377) with the memory editor, and then write a small program to use a pointer routine to step through and playback the images.

    Your pointer can be incremented or decremented either by an event, or by a timer, or both.

    Regards, Mike

    elevmike,

    This is just what I'm looking for! If you have a spare moment, what might this program look like? (I am very new to all this and am not familiar with pointer routines) THANKS

    Oh, also; the pointer would be incremented by a timer that had a different specified value for each step. Thanks again.

    Dan,

    I'm sorry I didnt catch your reply till just now. If you can provide me your email, I can send you a copy of my christmas light show program. I'ts time driven, but you can change it to be event driven.

    Mike.
