    4) MIDI IN - MIDI data is received at this port. When MIDI data is received, the MIDI indicator in the dis- play flashes on and off. 5) MIDI OUT / THRU - Merges MIDI data generated by the Studio 400 with MIDI data received at the input. Please see pg. 32 for more information.

  • Page 9: Making Connections

    (such as mixing console inputs). This method is called the "in- line" method because the Studio 400 is connected directly in the audio path of the source. When you use the in-line method, the master wet-to-dry effects mix is controlled from the Studio 400 operating system.

    Program OFF, but the Dry Levels defined in that Program remain untouched. If the effects are all wet (no Dry Level), the Bypass function effectively Mutes the Studio 400. If the Dry Level is up, then the Studio 400 passes the original signals through without processing. A line through the modules in a Effect Configuration Matrix indicate that the module is Bypassed.

  • Page 12: Section 2 - Basic Functions Of The Studio 400

    GETTING AROUND THE OPERATING SYSTEM The menu structure of the Studio 400 has been specially designed to be easy to use. The display shows the information you need, but to make things even easier for you, illumination in the front panel buttons offers additional operating information.

    Low Frequency Oscillator (LFO) or MIDI Continuous Controller information. Every Program in the Studio 400 has a set of Modifiers. Up to 8 Modifier links can be assigned to control parameters. There are three types of Modifiers that can be linked to a parameter: MIDI CCs, LFOs, and Dynamic (signal level dependent).

  • Page 15: Linking A Parameter To A Modifier

    LFOs - When you use LFOs, Parameter values can be controlled automatically between a defined mini- mum and maximum setting at a rate set by the user. The Studio 400 has 2 user definable LFOs in each program that can be assigned to any Parameter.

  • Page 16: Setting Up An Lfo Or Dynamic

    • Press <3> and use the Data wheel to adjust HiThrs. The HiThrs control sets the point at which maxi- mum Parameter modification occurs. • Press <4> and use the Data wheel to select the source input you want the modifier to "listen" to, or follow.

  • Page 17: Comparing Programs

    Compare function. To compare an edited Program with the original Stored version, do the following: • While the Studio 400 is in program mode, press the <PROGRAM> button once. The top line of the display reads: *COMPARING ORIGINAL PRG*. When this message is displayed, the stored Program is temporarily loaded and active.

  • Page 18: Section 3 - Effects And Parameters

    Likewise, the Module sizes available in the Studio 400 are Quarter (module type = 4th ), Half (module type = HLF ), and Whole (module type = FUL ). This simply means that FUL module type offers effects with more flexibility and power than the HLF mod- ules, and so on.

  • Page 19: Reverbs

    Studio 400 Owner's Manual DIGITAL AND ANALOG EFFECT LIST Within the Studio 400, lies a vast palette of Digital and Analog effects. All of which are Studio quality. The following is a list of the Effects available: Reverbs, Choruses, Flangers, Phasers, Rotary Speaker Simulator,Tremolo, Auto-Panner, Pitch Shifters, Detuners, Delays (Digital and Analog), Equalizers, Noise Gate, and Compressor.
  • Page 20 Studio 400 Owner's Manual Reverbs PARAM. DESCRIPTION FX: Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%. Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Balance Controls the left/right positioning of the dry signal in the stereo soundfield. Varies from -99 (all left) to 99 (all right).
  • Page 21 Studio 400 Owner's Manual Reverbs (continued) PARAM. DESCRIPTION Blend The BLEND control cross-mixes reverberations from the left side into the right side and vice-versa. This can be used to increase the realism of the simulated room by adding reverberations from different parts of the room to each channel. Varies from 0% to 99%.

  • Page 22: Chorus And Flange

    Studio 400 Owner's Manual CHORUS AND FLANGE Both choruses and flangers use a Low Frequency Oscillator (LFO) to produce their rich, swirling effects. When you change the speed and depth Parameters of modulation effects, you're actually controlling the frequency and amplitude of the LFO. These settings determine the rate and intensity of the modulation effect.
  • Page 23 Studio 400 Owner's Manual Flangers PARAM. DESCRIPTION FX: Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%. Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Balance Controls the left/right positioning of the dry signal in the stereo soundfield. Varies from -99 (all left) to 99 (all right).
  • Page 24 Studio 400 Owner's Manual Choruses DESCRIPTION PARAM. FX: Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%. Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Balance Controls the left/right positioning of the dry signal in the stereo soundfield. Varies from -99 (all left) to 99 (all right).

  • Page 25: Phasers

    Studio 400 Owner's Manual PHASERS Phasers create a copy of the original signal and modulate that new signal’s phase relationship to the origi- nal signal. When the two signals are reunited at the output, the modified signal, moving smoothly in and out of phase, causes continuous cancellations and reinforcements at different frequencies throughout the modulating cycle.

  • Page 26: Tremolos, Auto Panners And Rotary Speaker Simluator

    Studio 400 Owner's Manual ROTARY SPEAKER SIMULAOR / TREMOLO / AUTO PANNER The Rotary Speaker Simluator allows you to emulate the classic rotating speaker sound, without the chiro- practic problems that come with moving bulky speaker cabinets. Tremolos and Auto Panners are similar to one another because they use an LFO to modulate the level of the signal.

  • Page 27: Detuners And Pitch Shifters

    50%, the pitch is exactly one semitone (50 cents) up from the original. Pitch shifters allow you to create multiple voices from a single note input. In the Studio 400, the new pitch is determined by the setting of the SHFT Parameters, which can cover a pitch range of four octaves.
  • Page 28 Studio 400 Owner's Manual Pitch Shifters PARAM. DESCRIPTION FX: Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%. Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Controls the left/right posistioning of the dry signal in the stereo soundfield. Varies from Balance -99 (all left) to -99 (all right).

  • Page 29: Delays

    "sampled" or recorded into memory, where it is held for the amount of time you specify with the delay time setting, after which the sample is replayed at the output. The Studio 400's delays have a feedback meter that is used to send a portion of the delayed signal back to the input to be re-recorded along with new source material.

  • Page 30: Eqs

    Studio 400 Owner's Manual EQUALIZERS The Studio 400 has a broad selection of equalizer Modules to cover virtually any need. Both mono and stereo modules are available. Remember that mono equalizers connected to stereo sources will always sum the stereo signal together for equalization (thus eliminating the stereo image). If you need to maintain the stereo image, use a stereo equalizer module.

  • Page 31: Noise Gate And Compressor

    Studio 400 Owner's Manual NOISE GATE / COMPRESSOR Noise gates are particularly useful for preventing mic rumble, wind noise, or hum from getting to tape in your recordings, or for gating drum kits to prevent mic bleed. Compression does exactly what its name implies; it compresses the dynamic range of the signal. It does this by turning signals down as they become louder.

  • Page 32: Multi Effects

    Studio 400 Owner's Manual MULTI EFFECTS MODULES The Studio 400, Multi Effect Modules allow the User to combine either Delay and Chorus or Delay and Flange within one Effect module block. This is ideal for situations where the User needs to add another effect to the Effect Configuration, but is running low on signal processing resources.

  • Page 33: Section 4-In Levels And Utilities

    The concept of Auto Leveling is simple: the Studio 400 listens to the signal for about 8 seconds, and sets the input levels accordingly. You also have the option of leveling the inputs manually if you want.

  • Page 34: Utility

    • To return to Program mode, press <PROGRAM>. MIDI CHANNEL This option sets the MIDI Channel that the Studio 400 will respond to MIDI program changes and CC mes- sages. MIDI Channel settings include: Off, 1, 2,...15, 16, and All.

  • Page 35: System Exclusive Device Channel / Midi Merge

    Note that the number under STUDIOUSER changes along with the MIDI number. • Press <3> and use the Data wheel to select the Studio 400 Program you want the selected MIDI Program change number to recall. As this number increases above Program 100, note that STU- DIOUSER changes to STUDIOFACT, indicating that the mapped number will recall the indicated Program number in the Factory bank.

  • Page 36: Program Dump

    This option allows you to dump all resident Programs in memory to an external recording device, like a patch librarian, computer, or sequencer for backup, storage, or organization. This option dumps all Programs simultaneously. It does not send any Studio 400 system information, such as SysEx Device channel or Program maps.

  • Page 37: Program Autoload

    • When you're finished, you can return to Program mode by pressing <PROGRAM>. FACTORY RESET Allows you to erase all User Program and Utility settings at once and restore the Studio 400 memory to its factory condition. WARNING! This procedure will destroy and reset ALL User Programs in the Studio 400's memory. Be sure you want to erase the memory, and start fresh before continuing with this procedure.
