saved setups and saved programs and replace them with the received setups and programs. (Note: The current setup and the currently running programs will not be altered.)

dump card This function dumps all setups and programs stored on the Memory Card. If received at the MIDI In port or at the serial port, the H8000FW will erase your Memory Card and replace its contents with the received setups and programs. If there is no Memory Card in place or if the Memory Card is too small, the incoming data is ignored.

dump internal This function dumps the contents of the internal memory. This is the same as using dump files, dump setup, and dump program for each DSP. It dumps all the setups and programs stored in internal memory, along with the current setup and the programs running on DSP A and DSP B. If received at the MIDI In port or at the serial port, the H8000FW will replace all of its setups and programs, load the two new programs on their respective DSPs, stop all operations and start as if from power-up, using the new setup and programs.

If the device to which you sent the dump has the ability to send it back again (such as a sequencer), you can use this as a way to "back up" your H8000FW.

WARNING: If, for any reason, this dump gets corrupted in some way and you send it back to the H8000FW, you will lose all the information you are trying to back up, as well as the H8000FW's contents. If you do a "backup" in this way, especially to a computer, it would be a good idea to do it twice, to two separate files, and then to compare the files. If they are identical, it’s a good indication that the data sent from the H8000FW has been recorded accurately.

Controlling One H8000FW from Another H8000FW

The H8000FW can send system exclusive messages detailing all changes to its parameters, both effects-program specific and SETUP values. The H8000FW is designed so that a sequencer can receive and then play back these values to the same the H8000FW, but we can also use this feature to slave one H8000FW to another.

To slave one H8000FW to another:

141

set the parameter sequence out found on the midi/ext menu page in the SETUP area to off on the "slave."

On the same menu page, set the

parameter sequence to new on the "master."

On the same menu page, set the parameter MIDI to enabled on both units.

On the same menu page, set system exclusive to on for both units.

On the same menu page, set device ID to a common value for both units.

Connect either the MIDI Out port of the "master" to the MIDI In port of the "slave" or connect their serial ports. (Using the serial ports will require a special null modem cable, with pin 2 of each end connected to pin 3 at the other, and vice versa.)

Now, changes made on the "master" are echoed on the "slave." Be sure to leave sequence out to off on the "slave" or MIDI "feedback" will lock up the H8000FWs in a very bad sort of way.

Sending A Program From One the H8000FW to Another

To send a program from one H8000FW to another, turn sequence out to off on the midi/ext menu page in the SETUP area on both H8000FWs. On the same menu page, change the device ID of each the H8000FW so that they agree. Then connect their serial ports or connect the MIDI Out port of the "sender" to the MIDI In port of the "receiver." Make sure the program you would like to send is running on the currently displayed DSP on the "sender" (press the DSP A/B key to toggle the display). Make sure that the DSP you would like to run the program on in the "receiver" is the currently displayed DSP* (press the key to toggle the display).

To read about using the serial ports, see Setting Up the Serial Port on page 139.

On the "sender," highlight dump program on the dump menu page in the SETUP area and press the SELECT key. The program will be loaded on the "receiver." Before doing anything else, you should change the device ID of one of the H8000FWs so that it is no longer the same as the device ID of the other. Failure to do so could cause problems later if sequence out gets set to on on both H8000FWs!

* If the upper left-hand corner of the screen reads “A,” the “currently displayed DSP” is DSP A. If the upper left-hand corner of

the screen reads “B,” the “currently displayed DSP” is DSP B. Both DSPs are always running, but only the parameters for one of them can be displayed at a time.

Sequencing With MIDI

Most MIDI sequencers will receive system exclusive messages and store them for later playback on the originating instrument. The H8000FW fully supports this. Instead of sending keyboard presses and knob turns, the H8000FW sends "parameter change messages." When a sequencer sends a "parameter change message" back to the H8000FW, the corresponding parameter is adjusted. This is true whether the display is showing the parameter or not. Further, you can operate the front panel of the H8000FW as you normally would while it’s receiving "parameter change messages" from a sequencer.

The H8000FW uses a "new" ASCII-based sequencing protocol that is superior to the "old" protocol found on earlier Eventide products. When you turn sequencing on, you can select which of these protocols to use. Unless you're reading an old sequence or have to ensure compatibility with older machines, we suggest you use the "new" protocol.

To actually sequence, set sequence out (on the midi menu page in the SETUP area) to new. Every time a parameter is changed, a corresponding message is sent out the MIDI

Out port and the serial port as a system exclusive message. By recording parameter changes to a MIDI sequencer, you can automate your mixdowns.

Simply play back the recorded MIDI sequence at the H8000FW’s MIDI In, and you will see the changes you recorded "played" by the sequencer (assuming MIDI is enabled, system exclusive is on, the programs that were loaded when the sequence was recorded are loaded during playback on their respective DSPs, and the device ID set during recording is set during playback). However, if you manage to configure the MIDI connections between your various pieces of equipment such that the "system exclusive, sequence out" MIDI messages of the H8000FW loop back into the H8000FW without delay, digital demons will unleash a raging fury inside your helpless H8000FW. So, make sure that doesn’t happen! If you aren’t actively using the sequence out feature, it’s wise to leave it off. Leave sequence out on and system exclusive off while recording a sequence, and sequence out off and system exclusive on while playing the sequence back unless you require the "echo" feature discussed below..

All adjustments made to the H8000FW while the parameter sequence out is set to on are sent out the MIDI Out port and the serial port (not including Patch Editor commands). This includes any changes received at the MIDI In port. If the MIDI sequencer is sending data to the H8000FW and receiving data from the H8000FW at the same time, it will receive an "echo" of the commands it sends to the H8000FW. This means that if you change something on the H8000FW while sequencing (and echoing),

143

then your changes will also be sent with the echo information to the sequencer. This might be useful for editing or touching-up a sequence.

The sequence out capability can also be used to allow one H8000FW to control another. Connect the MIDI out from the master to the MIDI in of the slave, and the slave will follow the master. Similarly, connect the MIDI thru of the slave to the MIDI in of a third H8000FW, and it too will follow the master.

Connecting user-supplied crystals and external clocks

User-supplied Crystal Oscillators (H8000 and H8000A only)

A user-supplied crystal oscillator may be installed to give sample rates beyond those offered by the H8000, such as 32kHz or 44.056kHz. This oscillator should be installed in the socket at location Y401 on the H8000's motherboard. The oscillator should run at 256 times the desired sample rate and should be similar to the "Fox" 1100E type used elsewhere on the motherboard. (Fox Electronics, Florida, tel: 813 693 1554.)

See Miscellaneous Setup Options on page 138 to enable the use of User-supplied Crystal Oscillators.

Since this socket connects directly to the H8000's internals, incorrect usage may damage the H8000's circuitry and is NOT covered by the Warranty.

Highlight format internal and press the SELECT key. You’ll arrive at the screen shown to the right. Pressing the <yes> SOFT KEY will delete everything you have stored in the

H8000FW, returning it to the state in which it left the factory. Do not do this lightly. Pressing the <no> SOFT KEY will abort the mission.

Internal memory "checksum errors" should occur infrequently, if ever. Should they occur more frequently than "almost never," contact Eventide, as something is definitely amiss.

Fixing PCMCIA SRAM Memory Card Problems

Note - the following only applies to PCMCIA static RAM memory cards.

If a Memory Card "checksum error" occurs, your Memory Card has been corrupted in some way. It is possible that there is no loss of data. Memory Cards can be corrupted by static

electricity, shock, a loose battery, older siblings, a weak battery, incorrect insertion into the H8000FW, use in some other computer, or a myriad of other causes. As a result, a Memory Card "checksum error" should not immediately send your heart into your mouth (although an internal checksum error probably should). Regardless of whether you are concerned about a Memory Card "checksum error" or not, you should "fix" the checksum.

Go to the service menu page in the SETUP area.

Highlight fix card and press the SELECT key. Press the <yes> SOFT KEY to force the new checksum result to be saved. If data is in fact corrupted, this will not fix it. Press the <no>

to abort.

If you are worried about the contents of the Memory Card, you should either dump the contents of the memory card to an external storage device

Dumps on page 140) OR copy all valuable internal programs and routing configurations to a different Memory Card, copy the faulty Memory Card’s programs and routing configurations to internal memory and then to another Memory Card (see Copying Programs

on page 129).

Finally, return to the service menu page in the SETUP area.

Highlight format card and press the SELECT key. Pressing the <yes> SOFT KEY will erase the contents of the Memory Card and reformat it. Press the <no> SOFT KEY to abort.

148

You might also put a label on the card (using adhesive tape, indelible marker, etc.) indicating the date and that a problem occurred. Keep track of this kind of problem and make multiple backup copies. Have you been introduced to Mr. Murphy? He’s got this law that says . . .

Changing the Internal Battery

A small button-type battery is mounted internally and powers the H8000FW's memory when the power is off. This should last about five years before it needs to be changed, longer if the H8000FW is left powered up much of the time. The number of hours for which the unit has been operating, powered and unpowered, can be found under SETUP/service/information.

This battery should be replaced by a qualified technician only since it must be replaced when the H8000FW is powered up in order to preserve the internal memory contents. Contact your Eventide Service Center to have this battery replaced.

IMPORTANT SAFETY NOTICE FOR LITHIUM BATTERY:

Danger of explosion if battery is incorrectly replaced.

Replace only with same or equivalent type recommended by manufacturer.

Dispose of battery according to manufacturer's instructions.
