  • Page 11 Display while in Play mode (the length of the recorded material), which will be less than the total length available for recording. If the MoreLoops parameter is greater than one (see MoreLoops in the Reference section), then the Echoplex will hold several different loops. In this case, one loop will be active at any given time, and we’ll call this the current loop.
  • Page 12 It is possible for the user to force a Rounded action to end without Rounding. This is referred to as an UnRounded operation. For example, an UnRounded Multiply is a Multiply that is forced to end without reaching the end of the cycle. iii-4 Echoplex Digital Pro Plus User’s Manual...

    Quick Start ongratulations! You’re in for more fun than you can possibly imagine, playing music with the Echoplex Digital Pro Plus. This is the spiritual successor to the original Echoplex, a device made by Maestro in the 1960s that relied on tape loops to create effects. It was used extensively by the Jimi Hendrix, the Doors, and many others.

All that’s required is that the Voltage Selector Switch be set properly and the proper power cord be attached to the Power Input Jack.

  • Page 31: Stereo Operation

    T E R E O P E R A T I O N You can use a pair of Echoplex Digital Pro Pluses to loop stereo signals. A BrotherSync connection will ensure that the two halves of the signal maintain their phase relationships through loops of any length. A MIDI connection provides simultaneous control over the process.

  • Page 43 8ths/Cycle Continued M I D I C L O C K I M I T S There is a limit to how fast the Echoplex will transmit MIDI clocks—the equivalent of about 400 beats per minute. If you create a loop that’s 1/2 a second long with 8ths/Cycle=16, then that 1/2 second will represent 2 measures, or 8 beats.

See the discussion under the SwitchQuant heading in this chapter for a full explanation and examples. See also: NextLoop, SwitchQuant, AutoRecord 4-30 Echoplex Digital Pro Plus User’s Manual...

  • Page 69: Looptrig

    LoopTrig Default: 84 Parameter Row: Loops Determines which MIDI note numbers will trigger loops. Values: 0-127 When multiple loops are set up using the MoreLoops parameter, incoming MIDI NoteOn messages can trigger any loop’s playback. This function is called LoopTriggering, and is described in more detail in the functions section.

  • Page 70: Moreloops

    Multiply. This is called a GeneralReset. Both types of Reset are also available as DirectMIDI commands. See Also: LoopCopy, NextLoop, AutoRecord, LoopTrig, SamplerStyle, Velocity, Multiply, SwitchQuant 4-32 Echoplex Digital Pro Plus User’s Manual...

  • Page 71: Mutemode

    MuteMode Default: Continuous Parameter Row: Switches Determines how sound is restarted after it is muted. Values: Continuous (Cnt), Start (StA) MuteMode determines where loop playback starts the second time you press the Mute button to UnMute a loop. Whichever approach you choose, the Undo button takes the opposite viewpoint, so you’ll always have both ways to end a Mute readily available.

  • Page 72: Overdubmode

    Echoplex. You will always know the state of Overdub by whether you are pressing it or not. See Also: Overdub 4-34 Echoplex Digital Pro Plus User’s Manual...

  • Page 73: Overflow

    Overflow Default: Stop Parameter Row: Switches Determines how Record handles memory overflows. Values: Stop(StP), Play (PLY) An overflow occurs when you attempt to use more memory than you have during Record operations. When Overflow=Stop, exceeding the memory capacity of your unit will cause the Record operation to be immediately cancelled, and will reset (erase) the current loop.

  • Page 74: Quantize

    If you are using MIDI, both Reset and GeneralReset are available independently as DirectMIDI commands. So with MIDI, reset is not a problem. 4-40 Echoplex Digital Pro Plus User’s Manual...
  • Page 79 RecordMode Continued Also note that if you are using MIDI there is a DirectMIDI command for independent sustain action Record. This command is called SUSRecord and is located at Source# + 14. ECORD RecordMode=Safe is just like RecordMode=Toggle except that after a Record the Feedback is always set to 100%.

  • Page 80: Reserved

    Now Presets Parameter Row: Switches This is now called Presets on current Echoplexes, and it accesses the Preset Editor. If you have an older Echoplex with a “Reserved” parameter, see the Preset section. 4-42 Echoplex Digital Pro Plus User’s Manual...

  • Page 81: Roundmode

    RoundMode Default: Off Parameter Row: Switches Determines whether certain material will be recorded. Values: Off (OFF), Round (rnd) During Multiply and Insert operations, which always are active for an exact number of cycles (unless ended with the Record button), this parameter determines whether new material played after the second press of the button but before the end of the current cycle will be recorded.

  • Page 82: Samplerstyle

    ‘B’ or ‘C’ section to drop in for one repetition before returning to the main loop. With SamplerStyle=One you can do this with one press on NextLoop and let the Echoplex take care of everything for you. 4-44 Echoplex Digital Pro Plus User’s Manual...
  • Page 83 SamplerStyle Continued (Att) TTACK When SamplerStyle=Attack, a MIDI note will cause the loop will trigger from the beginning play as long as the triggering note is held down; i.e., until a NoteOff or a different triggering note is received. This type of action with SamplerStyle=Attack only makes sense when loops are triggered by MIDI.
  • Page 84 Similarly, if you press any additional function during the quantizing period, it does not switch back to the previous loop. The Echoplex assumes you want to elaborate on the B part. See also: LoopTrig, Velocity, NextLoop, SwitchQuant 4-46 Echoplex Digital Pro Plus User’s Manual...

  • Page 85: Source

    Source # Default: 36 Parameter Row: MIDI Determines the starting note number, or controller number, for MIDI control of Echoplex operations. Values: 0-99 The Source# parameter determines the base note or controller number from which all the other MIDI commands are referenced. All buttons and functions are assigned to notes or controllers based on this parameter value.

  • Page 86: Switchquant

    When NextLoop is pressed the Echoplex immediately switches to the next loop with no quantizing. For example, if you are currently on loop 2, pressing NextLoop will instantly put you in loop 3. 4-48 Echoplex Digital Pro Plus User’s Manual...
  • Page 87 SwitchQuant Continued ONFIRM WITCH UANT When NextLoop is pressed the Echoplex goes into the quantize period but then waits indefinitely with the current loop playing until a confirming action is made. During this waiting period you may continue to press NextLoop to select different loops without actually switching to them.

  • Page 93 SwitchQuant Continued If the destination loop has material in it already, pressing Overdub during the quantize period will turn Overdub on when you switch to the new loop. R e c o r d Pressing Record during the quantize period will cause the Echoplex to begin recording immediately as soon as it enters the next loop.

  • Page 95: Sync

    Sync Default: Out Parameter Row: Timing Synchronizes the Echoplex Digital Pro with another Echoplex Digital Pro, a MIDI sequencer, a pulse trigger device, or a sound source. Values: Off (OFF), Out, OutUserStart (OuS), In (OFF) No synchronization signals are received or sent. MIDI: MIDI clocks are sent out the MIDI Out port when a loop is recorded or a Tempo is preset.

  • Page 97: Threshold

    Threshold Default: 0 Parameter Row: Timing Tells the Echoplex to wait until you play before starting to record. Values: 0-8 When a non-zero value for the Threshold parameter is set, the Record function waits until a large enough audio signal appears at the Input jack before it actually starts recording.

    Transmitting MIDI Commands Immediate Action Play Mode MIDI Commands are transmitted with each button press. When ControlSource is set to Notes, each press of an Echoplex button will send that button’s specific NoteOn message out the MIDI Out Port. The NoteOn message is sent when the button is pressed, and the corresponding NoteOff message is sent when the button is released.
