>>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.
