Korg Poly800/EX800 Users

is there a reason that my old poly-800 won't hold it's program.
it works fine, but, turn it off and everything is gone.
is there something hiding inside to look for.

thanx,

andy

it'll be the battery, i think its just a PC CMOS battery
just be carefull soldering it back in, apparently it can kill
them, edd

Yep, I changed mine a couple years back.  Seems like it was only the center conductor contact that was soldered.  It wasn't too bad, just use the coolest iron you can get.  (I have one of those butane irons from Radio Shack...very nice..infinitely adjustable...just don't use around combustibles!)

Ciao bella!

also VERY easy to burn yr fingers to a crisp on the exhaust port.. and melt unsuspecting plastics!

You DO have to be careful.  It also makes a great backup cigarette lighter!

Since all you need to do is ensure that /CE is high and there is power
to the chip, it should be easy enough to bodge in the required diode,
resistor and battery to any model.

BTW, you really only need two wires. I just used a third because I already had the 3-wire jumper cable laying around. You can find two-wire jumpers here that will probably work better:

Mike seems to be too modest to mention that if you buy his Tomahawk kit, you won't need the internal battery for patch backup anymore. Sure it's a lot more expensive than a battery, but since you have to break out the soldering iron either way, why not install a Tomahawk kit instead of a battery?

Thanks zoinky!

Now overcoming my modesty I will also point out that you get a whole bunch of cool new features for your Poly-800 which I list below.

The only down side is that the tape load and save doesn't work anymore.

The NEW SOUND FEATURES are:
1) Portamento mono mode with slide rate parameter stored per patch.
2) Tremolo - apply either LFO1 or LFO2 to the volume of either of the DCO's volume with control over Tremolo depth for each DCO.
3) The single LFO is now two (LFO1 and LFO2) and two more super LFO's (SLFO3 and SLFO4) have been implemented.
4) All four LFO's have triangle, sawtooth, sine, square PWM and random
sample and hold waveforms. All waveforms can also be inverted.
5) All four LFO's have free running modes.
6) LFO1 and LFO2 delay type select - allows the LFO's to cycle at note
on and then stop cycling when the delay timer expires. This allows the
reversal of its original behavior where the LFO delay timer must expire
before the LFO begins to cycle.
7) LFO2 sync to MIDI clock.
8) EG3 retriggering sync by MIDI clock.
9) Note triggered sequencer transpose - You can now select a global
parameter that will set up the keyboard to transpose the playing
sequence. You can also set the mode to allow MIDI to transpose the
sequencer too.
10) Resonance can now be modulated by LFO's and the envelope generator.
11) The LFO1 frequency can be modulated by SLFO3.
12) The LFO2 frequency can be modulated by SLFO4.
13) Random sample and hold waveform clocked by the on board seq. or MIDI clock.
14) Random sample and hold waveform clocked by sequencer repeat.

The NEW MIDI FEATURES are:
1) MIDI controllers (special and NRPN) for all original and extended parameters.
2) MIDI standard controllers implemented for LFO1 rate, VCF cutoff and resonance depth.
3) MIDI controllers for setting Poly, Hold, Chord and Portamento modes.
4) MIDI sustain controller send and receive.
5) MIDI SYSEX single patch dump send and receive.
6) MIDI SYSEX bulk patch send and receive.
7) MIDI EX-800 SYSEX dump receive (sequencer and patches).
8) MIDI Poly-800 MK2 SYSEX patch dump receive (patches only).
9) MIDI user initiated SYSEX HAWK-800 bulk dump all patches.
10) Selectable Omni On, Off or Auto on power up.
11) Keyboard MIDI TX channel selection (1-16 or no MIDI TX).
12) Joystick MIDI TX channel selection (1-16 or no MIDI TX).
13) MIDI soft thru of all messages.
14) Sequencer MIDI time code send on/off.
15) Chord mode synchronization SYSEX send - if cascade sync mode is
selected then pressing the chord key will send a SYSEX message to set
up the chord progression table. This allows a slave unit such as an
EX-800 to operate in chord mode with the same chord structure as the
master unit.
16) MIDI patch bank selection (1 of 4).
17) MIDI note on velocity sensitivity where VCF and envelope generator
parameters can be influenced by incoming MIDI note velocity data.

The NEW USER FEATURES are:1) All notes off panic button (with MIDI TX too).
2) Local keyboard control on/off.
3) Local joystick control on/off.
4) Extended playing range on/off (increases the playing range by two octaves while ignoring the parameters 11 and 21).
5) Cascade mode (for when you have two Poly's or a Poly and an EX800. One unit plays odd notes and the other plays evens).
6) Cascade sync mode (the master unit sends SYSEX patch dumps to the
slave as well as setting the Poly mode and patch number. This ensures
that your slave unit plays exactly the same sounds as the master).
7) Poly mode is stored and recalled with patches.
8) Bend depth stored per patch.
9) You can send the global parameters from the Poly 800 to another Poly-800 or EX800.
10) A global parameter is now available that allows setting the keyboard MIDI note velocity.
11) Local sequencer control on/off so that you can send the Poly 800 sequence to another synth via MIDI.
12) A global parameter now allows keyboard MIDI transmit octave shift up or down 3 octaves.
13) You can cancel out of a patch write by pressing the write button
(instead of reaching around the back and fiddling around for the write
enable switch).
14) All user patches, globals and sequencer data are stored directly in
flash memory so that you no longer need ANY backup battery.
15) Sustain pedal operation. The original "step up" jack now also
operates as a sustain pedal with patch control over decay and release
times as well as sustain hold point.
16) Joystick parameter editing and patch section. You can now change
the operation of the joystick to edit patches and select patches.
17) The Up/Down data keys also operate as patch up/down selectors when in Program mode.
18) Four banks of 64 patches (for all kits shipped from June 2009
onward) giving the HAWK-800 256 patch storage in flash memory (no
backup batteries are required).

Mike
