    >>Can somebody hold my hand and walk me through 
    getting my QY70 to sync with 
my Echoplex? I have the 
    midi in set on the EDP and the midi out of my QY. 
I've followed the manual but can't get anything to work. 
    Help!?<< 
    I have a qy70, which I have use as master midi clock on 
    several occasions. CC's are continous controllers, like volume, pan, and 
    many others, the use of which varies from one box to another and can be 
    user-configurable, though there are some loose standards. one of the most 
    useful things about midi, especially for live music....
    but I digress. 
there's a page in the 
    qy70's midi menu where you can select the clock mode to either master or 
    slave; the thing is probably already in the right mode as it won't start at 
    all in slave mode unless there's incming clock, so it ain't that.... but 
    check it anyway. 
    I don't know the edp's midi implementation, but maybe it's 
    not responding to midi-start commands. 
    the other annoying thing about the qy70 (and the other 
    little yamaha units that support XG, their own version of general midi- 
    supposedly a universal orchestration standard) is that whenever you start a 
    pattern or song on the qy, it sends a little salvo of CC's and PC's 
    (programme changes) to set up XG parameters in the remote device so that the 
    songs play with the right settings. it's quite possible that the EDP is 
    responding to one of these. make sure that the channel-specific control of 
    the EDP is selected to a midi channel that the qy70 isn't broadcasting; the 
    qy can be "told" to operate on one of two groups of 8 channels (1-8 or 9-16) 
    and persists in setting up the XG parameters even on empty tracks... so you 
    want to make sure that the EDP is ignoring all that and just listening for 
    system realtime stuff- start/clock/stop and possibly song-pointers if this 
    is relevant.
    the qy series of "walkstations" have some limited potential 
    as midi-loopers; this is prompting me to dig mine out and play with it 
    again....
    duncan.
