it seems to me that you might be refering to
a given track outputing but also rechanellizing to another track and
then that track outputing to the original where as before I was only
talking about one initial track - is this the case ? I am not using
any external midi gear - I just want to stay in the XX7 and yet go
beyond it's parameters if so possible the thing is that there might
be some code embedded in the XX7 that actually prevents this sort of
thing from happening which is also what I am asking - what exactly gets
sent out and if rerouted what gets interpreted as actual effect during
imput - if other gear is used for effects - does it correctly interpret
the sysex or will it leave it only as note on or off ... how can a
rechannelized track be set up so that it acts as though it is
continues or realtime and still keeps changing the effect
information ...

MIDI stands for Musical Instrument Digital Interface.

MIDI allows for communication between diferent devices.

With MIDI no sounds are transmitted from one device to another.

With MIDI data can be sent from one device to another. This data is 
useful insofar as it conforms to MIDI specs.

MIDI data includes note on, note off, program change, continuous 
controller, etc.

MIDI recorders [sequencers] record, store, and playback MIDI data. 
They may also let you edit MIDI data.

I am not sure what you mean by MIDI echo?  Where did you see or hear 
about it? If it is online, please post the link.

(BTW, what specifically are you trying to do with your E-Mu--other 
than use it to its maximum capabilities?)

Finally, forget about sysex [system exclusive messages]. If you are 
staying within the E-Mu and not connecting it to any other gear, you 
do not need to do anything with sysex.

If you want to create echo effects with your E-Mu, there are several 
ways to do it. The method you use depends on what you want to do. 
Three basic methods I can think of are (1) use the effects 
processor, (3) use the sequencer, and (3) use the E-Mu synth engine. 

Using the synth engine you could use envelopes and patch cords, for 
example. You could use a lfo [low frequency oscilator] to modulate 
amplitude to simulate an echo.

Using the sequencer, you could copy a track, shift the start time of 
the notes a few ticks, lower the velocity, and play it at the same 
time as the original.  In fact, if you shift the start times, lower 
the velocity, and then merge those notes with the orginal track, you 
have what might be called midi echo. (I am not sure if this is what 
you meant in the first place.)

If you then take the new track [A + A'], shift the start time, scale 
down the velocity, and merge it again, you then would have each note 
4 times [A + A' + A" + A'"].

Hope this helps.
