897.0. "Korg Poly 800 Analog Synth and MIDI OMNI Mode" by NOFALT::NORCROSS () Thu Aug 06 1987 13:33

Anybody ever MIDI with the Korg Poly-800?  I'm having trouble
getting it *not* to play everything it hears on the wire (omni mode).

At one point in the manual it says that it is capable of playing
off any ONE of the 16 MIDI channels or ALL of the MIDI channels.

However, the MIDI Receive Channel Number parameter only goes from
1 to 16 (no 'zero' for omni mode). And the wierd part is that it doesn't
seem to matter *what* channel I set it to, it receives off of ALL
channels! How do I get the thing out of omni mode??

(I'm probably grossly overlooking something, but can anyone help?)

Thanks,
/Mitch

897.1Jes' a thought...JAWS::COTEBad Sneakers and a Pina Colada...Thu Aug 06 1987 15:354
    Is there a separate 'switch' for OMNI-ON/OFF, different from the
    receive channel selector????

897.2Any more suggestions?NOFALT::NORCROSSThu Aug 06 1987 15:564
If there is, I can't find it. I've looked. ..But, I'll look again.

897.3Is the EX-800 the same?CACHE::FONTAINEFri Aug 07 1987 19:4210
    My EX-800 powers up in omni mode until you select parameter 85 which
    is midi channel select. After that it defaults to poly mode on the
    channel you selected. Every time you turn it on after that, it comes
    up in omni mode until you select parameter 85 again, even though
    the channel number you set is retained. Also check that you're
    controlleris in the right mode.

897.4Still in omni mode...NOFALT::NORCROSSMon Aug 10 1987 14:2724
Re: all

Nope. None of these suggestions seem to work.

I can't find any physical switch to take the thing out of omni mode, and none
of the midi parameters available (midi receive channel 1-16, program change
enable, synch internal/ external) seem to have any effect on the problem
at hand.

Selecting and changing the midi receive channel after power up has no effect.

As for my controller, I am running a computer based sequencer, transmitting
one track at a time to different midi channels. The Poly-800 responds to
them all.

.....
Anyone know a Korg Customer Service number I can call?

Any more suggestions?

897.5Shot in the dark...JAWS::COTEARGH!!! Pitchbends from Hell!!Mon Aug 10 1987 14:5610
    Hmmm...
    
    Although Korg is (hopefully) different, Roland is notorious for
    hiding features in the boot process, ie: Hold parameter button n
    down while powering up.
    
    In order to get the JX3-P out of OMNI, I had to power up while
    holding button A7 down. Intuitively obvious....

897.6How 'bout it, Len?AKOV88::EATONDDeny thyselfMon Aug 10 1987 15:003
	I'm surprised Len hasn't pitched into this discussion.  He used to
have a Poly 800 and few people learn their instruments better than he does.

897.7Send it OMNI OFF!DRUMS::FEHSKENSMon Aug 10 1987 18:5312
    Len's been too busy to note lately.
    
    The POLY-800 powers up in OMNI mode.  It will respond to an OMNI
    OFF message over the MIDI input.  Many sequencers send OMNI OFF
    when they power up.  So, power up the POLY-800, *THEN* power up
    the sequencer, and you're out of OMNI mode.
    
    The EX-800 works a little more rationally.  Maybe there's a subsequent
    ROM rev to the POLY-800 that makes it work like the EX.

897.8how does he do it?JON::ROSSum....and twelve tones all in a row...Tue Aug 11 1987 13:3510
    wha?
    
    Len needs to give his brain to science when he goes....
    
    Len doesnt own a Poly800, does he? Yet he has ALL this
    
    information about it crainially carted apparently just for
    
    folks in need of it. AMAZING.      &*}
    
897.9Poly-800 ROM updateANTARE::NORCROSSTue Aug 11 1987 14:1325
Re: -.2

I guess my sequencer doesn't send an 'omni off' message on power up,
since order of power up doesn't have any effect on the 'omni mode
state' of the Poly-800.

(By the way, my sequencer is Master Tracks Pro running on a Mac. This
program does have the ability to send  System Exclusive 'dumps'. Maybe
I could get an 'omni mode off' command in there somehow?)

Re: all

I did speak with Korg USA (1-800-645-3188, very helpful). They say that
the 'Poly-800 ROM update' will take it out of omni mode (that's all it will
do). The parts are free, but I will have to pay the labor for an authorized
service center (LaSalle, Boston) to put'em in. They will only give the parts
to authorized service centers.

I should be bringing it in for the update in about two weeks...unless we
come up with a livable workaround for me.

897.10Sloppy solution...JAWS::COTEIF no guns THEN Abel alive...Tue Aug 11 1987 14:296
    I don't think OMNI-off is a sys-ex message.
    
    If you can work the logistics of transfer, I can make you an
    OMNI-OFF sequence...
    
    Edd
897.11My solution4GL::GLEASOND.A.R.Y.L.Tue Aug 11 1987 14:4315
    Edd's right; as I recall, OMNI-off is a standard MIDI message, not a
    sysex, so it's just a matter of sending 2 or 3 bytes, one of which
    indicates the MIDI channel.

    My HS-60 (which is a Juno-106 with built-in speakers) has the same
    problem, and I solved it by putting the OMNI-off bytes in the control
    sequence for the synth.  I use Dr.  T's Keyboard Controlled
    Sequencer, and my typical setup is to have a control sequence for
    each instrument, which fires off all the sub-sequences that are used
    by that instrument at the appropriate times.  I also have a master
    control sequence which sets the tempo and immediately fires off all
    of the instrument control sequences.

	On the Juno 106, while it fires up in omni mode, you merely have to
select a midi channel (press the MIDI button along with a bank/patch button) to 
switch it over into omni off.  At least that's the way I understood it.

897.13Master Tracks Pro Sysex DumpANTARE::NORCROSSTue Aug 11 1987 16:5819

I need to find out the details of this "system exclusive dump" feature
of the program.

It may be just a "dump", in which case I could put any midi messages I please
into the "send" file. (They may call it a "sysex" feature because that is what
it might be typically used for) 

Or, it may really be sysex specific.

I need to go away and study the animal before raising any more questions.

Thanks,
/Mitch

897.14I Actually Owned One, Ronny!DRUMS::FEHSKENSTue Aug 11 1987 20:1212
    My Juno-106 powers up in OMNI OFF, channel 1.
    
    I used to have a POLY-800 and EX-800.  The POLY-800 was my first
    synth.  Look what it did to me!  I traded them up to the Polaris,
    which I traded up to the JX-10.  The JX-10's gonna be around for
    a long time.
    
    OMNI OFF is not system exclusive, it's like the clock and start
    messages - not channel specific.

    BUT wow hey! what RECALL!
    
    synapses unite!
    
897.16Oops!DRUMS::FEHSKENSWed Aug 12 1987 13:2919
    Uhm, well, I never *claimed* to have flawless recall, you just all
    assumed it...
    
    I poked at the Juno last night, and it does in fact power up in OMNI
    mode.  I've just never seen it do that, because of the way I power
    things up and use them.
    
    It goes to OMNI OFF as soon as you select a MIDI channel from the
    front panel.  Curiously, it *sends* OMNI OFF, POLY ON when it powers
    up, so anybody connected to it will be OMNI OFF even though it's
    not.
    
    The JX-10 sends OMNI OFF, POLY ON when it powers up, *if* you're
    holding down the MIDI button on the front panel.
    
    Ain't standards wonderful?

897.17DX be a smart cookie!!!JAWS::COTEPractice Safe SysexWed Aug 12 1987 13:4910
    Of my 3 synths, the DX is the only one with a half an ounce of
    ROM when it comes to powerup time. It powers up in exactly the
    same state it went down in, even if you were editing at the time.
    
    The MKS comes up on channel whatever_you_left_it_on, but always
    patch 1-1.
    
    The mirage comes up OMNI-POLY, channel 1.

897.18How Easily They ForgetDRUMS::FEHSKENSWed Aug 12 1987 14:0314
    Uhm, Edd, regarding your current personal name, is that what those
    little plastic bags that the ram cartridges come in are for?
    
    MY SRVs are as smart as your DX, but the MKS-80 only remembers its
    channel number.  The JX will remember a lot of stuff if you tell
    it to, but like the MKS-80 it forgets in-progress edits and always
    powers up to bank 1 (or A), patch 1.  The MKS-80 at least remembers
    the bank (internal, cartridge A, cartridge B) it's in - the JX always
    defaults to the internal ram.  Both of them power up OMNI OFF,
    POLY ON - I think the only way you can get them into OMNI is via
    the MIDI input.

897.19Update ROMs workTACHYN::NORCROSSTue Sep 01 1987 17:5510
Just to finish my report here...

LaSalle has upgraded my Poly-800 ROMs. The synth still powers up in omni mode,
but can now be taken out of omni mode by selecting the midi receive channel
parameter on the keypad.

This turned out to be the only solution for me, given my setup.

Thanks,
Mitch
897.20VMSSPT::DICKINSONMon Jan 20 1992 15:2417
    
    Heres a weird story:
    
    I also have a poly800 and have seen this omni-on- all-the-time
    problem. Recently I ordered a tape from a music house in NY which
    contained some non-factory patches for the Poly800. After loading in
    the new patches via the Poly800's tape interface, I found that I indeed
    have 64 new patches (some are fairly interesting). By accident I have 
    also found that the receive channel parameter now works as it should.
    Must be the S/W for the poly800 that the Music house has is more recent
    than the tape that originally came with my poly800, and has somehow
    fixed the Omni problem in that if I set the Recv channel to say, 5,
    then it will only play data coming in on channel 5.
