Morse code. We’ve loaded the DSP7000 with features that put it in a class by itself. The variety and depth of its programs are truly amazing, from lush reverbs, to choruses, to flanges, to delays, to pitch shifters, to dynamics, to EQs, to filters, to distortions, to synthesizers, to samplers, to ring modulators, and to everything in-between. -

Page 15: Understanding The Display And Soft Keys
The DSP7000 Family Operating Manual Understanding the Display and SOFT KEYS Every “area” in the DSP7000 makes use of the display, so understanding the display is critical. A generic screen of the sort typically found in the area is shown below. It exemplifies various aspects of PARAMETER the display that remain constant no matter what area of the DSP7000 you’re in. - Page 16 Press it again to get a third menu page.

So, there you have it. The procedure we followed in this Quickstart section is more or less the procedure you will follow whenever you use the DSP7000. First, you’ll get an input level, then you’ll load a program, then you’ll tweak the parameters to “customize” your effect, and then you’ll save your tweak for later use. -
Page 27: Operation
Mounting and Handling Normally, the DSP7000 will be rack mounted in a standard 19 inch rack. If the rack will be taken on the road, the DSP7000 should be supported at the rear. It is advisable to keep the rack well ventilated and in a dry, dust-free environment so that heat and moisture won’t cause degradation of performance. - Page 28 The DSP7000 Family Operating Manual When a Memory Card is inserted, the DSP7000 may report that the card is not formatted and offer to for- mat it. If the Memory Card has already been formatted and the format question is presented, then there is a problem.

The DSP7000 Family Operating Manual Using an External Clock When you use the “external” clock, the system sampling rate will be that of the external digital signal. The sys- tem sampling rate is the sampling rate used for all internal processing (including the ADC and DAC). The external clock’s sampling rate is derived from the digital input. -

Page 38: External Controllers
External controllers are inputs to the DSP7000 that allow the modulation of parameters from a source out- side the DSP7000. These include the foot pedal jacks 1 and 2, the relay jack, and MIDI. In addition to modulating parameters such as delay times, pitch shift, LFO rate, etc., in programs, the external controllers can be used to modulate “box”... -
Page 39: Midi Setup
MIDI Setup In the DSP7000, MIDI can be used: • with programs that explicitly call for MIDI signals. For example, some programs in the DSP7000 act like synthesizers that a MIDI keyboard can play. • with programs that explicitly call for some sort of “external” controller. For example, the program “... - Page 40 ID device ID you’re using more than one DSP7000, you can set each one’s device ID to a different value.

Page 55: Program Load, Save, Delete, Etc
“...the DSP7000 is like a jungle gym for sine waves...” -Anonymous Programs are the “algorithms” used by the DSP to process signals. Programs are stored in the DSP7000 much like files are stored on your computer’s hard drive. Instead of using a hard drive, however, the DSP7000 uses RAM memory, either internally or on a card. -
Page 56: Creating A New Bank Or Renaming An Old Bank
The “Size” of a Program and Its Ramifications for Storage Finite things overrun the world we inhabit. There is a limit to the space available in the DSP7000 for the stor- age of programs. Not everything is perfect. Roughly 500 kilobytes of space is available for storing your pro- grams internally. -

Page 58: Triggering The Next Or Previous Program To Load
Triggering the Next or Previous Program To Load The DSP7000 can also advance to the next program (from the one that is currently loaded) or return to the previous program (from the one that is currently loaded) upon receipt of a “trigger” signal. -
Page 59: Updating A Program
Deleting a Program Because there is a finite amount of storage space in the DSP7000 or on a given Memory Card, you may want to delete some of your stored programs to free up “room” from time to time. To delete a program, go to the area and place the cursor over the program you would like to delete. -
Page 60: Linking" Programs
A link requires a paltry 38 bytes of storage space (recall that the smallest of programs require around 1000 bytes !). In reality, the link tells the DSP7000 where the program of interest is actually saved, but as far as you’re concerned, the link is the program of interest. -
Page 61: Comparing A Currently Loaded Program With The Original (Saved) Version
When confronted you say, “I just need to adjust the threshold one more time. Then I’ll stop. I swear!” You’re only kidding yourself... To keep you honest, the DSP7000 comes with a “compare” feature. It allows you to compare your tweaks with the original, saved program. You can then determine if your tweaks are helping or, God forbid, hurting the situation. -
Page 62: Parameters
Consequently, very little can be said about parameters generally. But that’s not much of a liability; parameters are easy to understand as you encounter them. Many, but not all, of the programs in the DSP7000 support an “expert mode” feature. The parameter controlling... -

DSP7000 expects to receive at the serial port. For things to work properly, these last four parameters must be set to the same values on both the DSP7000 and the machine connected to the serial port. Higher s result in faster transmission times, but baud rate most machines have a ceiling above which errors occur. -
Page 67: Dumping Data And Receiving Data Dumps
WARNING: If, for any reason, this dump gets corrupted in some way and you send it back to the DSP7000, you will lose all the information you are trying to back up, as well as the DSP7000's con- tents. 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. -
Page 68: Controlling One Dsp7000 From Another Dsp7000
The DSP7000 can send system exclusive messages detailing all changes to its parameters, both effects- program specific and SETUP values. The DSP7000 is designed so that a sequencer can receive and then play back these values to the same DSP7000, but we can also use this feature to slave one DSP7000 to an- other. -

This oscillator should be installed in the socket at location Y401 on the DSP7000's motherboard. The oscillator should run at 256 times the desired sample rate and should be similar to the "Fox"... -
Page 71: Service And Start-Up Options
The DSP7000 uses solid-state memory circuits to store programs and setup information. These circuits use a long-life battery to keep them alive while the DSP7000 is turned off. Whenever the computer in the DSP7000 updates that memory, it performs an operation called a “checksum” and stores the result. A checksum is a calculation whose result characterizes what is stored in memory. -
Page 72: Fixing Memory Card Problems
DSP7000, use in some other computer, or myriad other causes. As a result, a Memory Card “checksum error” should not immediately send your heart into your mouth (although an internal check- sum error probably should). -
Page 73: Changing The Internal Battery
A small button-type battery is mounted internally and powers the DSP7000's memory when the power is off. This should last about five years before it needs to be changed, longer if the DSP7000 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. -
Page 74: Start-Up Options
There are several “secret keys” that can be depressed during startup to perform special functions. These keys should be pressed and held down during the second “start-up screen” - the one with the "DSP7000" in large text. You can release the key once the appropriate “special screen” appears. -
