Basic Effects Mode
Introduction
Effects mode puts the power of an entire studioÑequalizers, signal processors, and mixersÑ
inside your K2600. It allows you to deÞne processing functions, signal paths, and balances, on
sounds created by the K2600 and, in Live mode, sounds from any source.
When youÕre in Program, Setup, or Quick Access mode, you can take advantage of
FX Modulation routings (FXMods, which are preset overrides for studio parameters) for real-
time control over any aspect of your studioÑeither from the buttons, sliders, wheels, and pedals
on your K2600, or from any MIDI source at all, like a sequencer or a dedicated controller.
Effects mode provides up to Þve individual effects processors. Four of these are designed to
operate on their own individual buses, and the Þfth, the ÒAuxiliaryÓ processor, is designed to be
global.
When the K2600 is being used multi-timbrally, Effects mode can provide separate processors for
each of several instruments. For example, letÕs say four K2600 channels are in use, under the
control of a sequencer. Each instrument on each channel can have its own processing: ßanger for
the piano, delay for the sax, compression for the bass, and tight reverb for the drums. Then all of
these signals could go through a global Aux processor, where they could be given a room reverb.
At the outputs of the K2600, the reverb could show up on one pair, while the other instrumentsÕ
dry or processed (prereverb) signals could show up at the others, either in mono or stereo. Or
the entire mix, carefully balanced and panned, could appear at a single pair, ready to be
recorded or played through a PA.

    Basic Effects Mode Terminology FXMods FXMods give you real-time control over many of the parameters within a studio. Parameters on any of the pages of the Studio Editor can be controlled by MIDI commandsÑsuch as physical controller input or sequencer dataÑor by internal K2600 functions like LFOs, envelopes, clocks, or key states.

    Basic Effects Mode The Effects Mode Page The OUTPUT page, where the signals coming from the FXBuses and Aux bus are routed to the K2600Õs eight physical outputs (analog and digital). The FX Preset Editor, which is nested within the Studio Editor, and which contains three pages. The FX Preset Editor is where you select algorithms and set parameters for the FX presets, as well as doing administrative things like naming and saving.

When FX Chan is Current , studio selection is determined by whatever program is assigned to the current K2600 channel (as shown in the top line of the display in Program mode or Effects mode).

    Each FX preset contains one algorithm. Just as you can use the same sample in more than one keymap, you can use the same algorithm in as many FX presets as you like. Although you cannot modify algorithms, additional effects algorithms will be available from Kurzweil on disk.

    Basic Effects Mode A Tour of Effects Mode A Tour of Effects Mode LetÕs take a tour through several studios. After you do this, you should have a pretty good idea of what itÕs like to work with Effects mode. You will still, of course, have many questionsÑ answering them is the job of the rest of this manual.
  • Page 13 Basic Effects Mode A Tour of Effects Mode The FXBus Page Now press Edit, and this page appears: EditStudio:FXBUS|Size:1|Free:3|<>FXBus:1 FX1||200*4|Tap|BPM|||||||||Aux||||Mix Wet/Dry||||:35%wet|||Lvl:3.5dB|Lvl:-4.5d Tempo||||||:120BPM|||Bal:0%||||Bal:0% Allocation:Auto <more||INPUT||FXBUS||AUXFX||OUTPUT|more> This is the FXBus page for FXBus1. It is where an FX preset is assigned to the FXBus. Put the cursor on the box containing 200*4 Tap BPMÑthis is the current FX preset, a four-tap delay whose speed is expressed in terms of tempo (Beats Per Minute).
  • Page 14 Basic Effects Mode A Tour of Effects Mode You can preassign a PAU value to an FXBus, in which case any FX presets that require more PAUs than you have given the bus cannot be loaded into the bus. If you try to put an FX preset into a bus that requires more PAUs than are currently available on that bus, the presetÕs name appears in parenthesesÑexactly the way a KB3 program appears if you try to select it on a channel thatÕs not the KB3 channel.
  • Page 15 Basic Effects Mode A Tour of Effects Mode Sends The third and fourth blocks determine the destinations of the Input A signal: each block can be set to route the signal to any of the four insert FXBuses, or to None. You cannot, however, set both blocks to the same destination.

    Basic Effects Mode A Tour of Effects Mode In this studio, Output A is carrying the Mix, that is, the combination of the outputs of the four FXBuses (only one of which is in use) and the Aux bus. Output B is carrying FXBus1, which is the signal after it passes through the delay on FXBus1, but before it gets to the reverb on the Aux bus.

The 145BP part refers to the fact that the delay times are based on a tempo of 145 BPM, As you play the guitar sound, the arrow next to FX2 ßashes, and it keeps on ßashing as long as the various feedback delays are sounding.

  • Page 20: A Complex Studio With Real-Time Control

    Basic Effects Mode A Tour of Effects Mode Output D has the output of the Aux bus, which is just the reverb signal, with no dry component, since the value of Wet/Dry on the AUXFX page is 100%. Note: If youÕre using the Mix audio outputs, keep in mind they carry the summed signals of audio outputs A through D.
  • Page 21 Basic Effects Mode A Tour of Effects Mode Setting the FX Mode To enable real-time control of the studio from the setup, we have to put the K2600 in the right Effects mode. Go to the Effects-mode page, and set FX Mode to Setup. FX Channel automatically goes to None.
