    I don't know anything about the E30 specifically, but the Roland gear I
    have seems to fall into two classes - things that don't change anything
    across power down/up cycles, and things that do.  The ones that do (and
    the E30 seems to be in this class) default to a particular patch at
    power up, usually A-1 or 1-1.  For my machines, almost all of the
    interesting parameters are patch-programmable, so by editing the
    power-up default patch (A-1, etc.), you can determine the power up
    state of the machine.
    
    I don't know if the E-30 has an analogous way of storing collections
    of parameter values.  If it does, this strategy might solve your
    problem.  If it doesn't, and the E-30 doesn't provide some specific
    way of editing its power up defaults (which ought to be described in
    the manual), you're stuck.

    I play in a duo using an E20 owned by my partner.  The setups she 
    wants to use on her solo gigs are completely different from the 
    setups I want to use in the duo.  The E20 also defaults to an 
    initial set-up mode.  
    
    The E20 has 8 user memory keys that contain user programmable 
    memories to define most of the front panel settings.  The only 
    things these user memories don't store are things like MIDI 
    channel #, tuning, and a few other goodies for advanced MIDI 
    applications.
    
    I got hold of a booklet from Roland UK called "E20 - Advanced Midi 
    Control".  It contains the MIDI command streams necessary to 
    interrogate and alter the internal configuration of the E20.  
    I use an Atari and Sattelite from Steinberg to send the command 
    streams and receive/dump the data.  I think BUMP will also do the 
    job. You cannot initiate a dump from the E20 - it has to be done 
    from the remote device.
    
    I have been successful in dumping the 8 user memories and the 
    three song memories to Atari disk, and reloading them to the E20.  
    I have also successfully transferred these dumps onto a Brother 
    MDI40 hardware sequencer as bulk sysex files, and loaded them into 
    the E20 from the MDI40.
    
    I also worked out the codes I need to receive/dump the MIDI 
    channel and tuning data, but I have not yet got that to work - I 
    think I'm having problems with the CRC which you need to generate, 
    but it could be that the dump codes for this area appear to be 
    D110 compatible, and I've also got a D110 in the network, so maybe 
    things are getting confused.
    
    FYI, the sysex dump request for the E20 front panel user memories 
    is:
    
    F0 start sySex
    41 Roland							      
    10 Unit #
    21 model #
    11 Request data (One way dump)

    7E Address
    00 Address LSB
    00 size MSB
    01 size
    18 size LSB
    69 checksum
    F7 end of exclusive
    
    Hope this helps - good luck!

    Having read your note again, I realise that I am not changing the
    actual setup on power on independant of the user settings.  I reckon
    it will always default to this setup, but I also imagine that it would
    be possible to alter the parameters directly after power on without
    recourse to the patch memories.  However, I don't think it would be
    that easy to work out the codes required, and as I've now got the
    equivalent of an infinite number of patch memories, I don't think its
    necessary either.
