The Effects Sends

On a mixing console you can control the amount of signal each channel sends to the effect bus. This lets each channel be placed in a slightly different “sonic space” creating an airy, open sound.

Unlike a mixing console, EOS uses this basic concept, but works in a slightly different manner. There

	dry (no effect). A setting of 50% contains an equal mix of affected and
	normal signal.

The submix bus selection is programmed for each voice in the Preset Edit, Amplifier screen (see “Amplifier/Filter” on page 341). These settings can be overwritten in the Multimode screen by changing the submix setting from “Voice” to “Sub 1, 2 or 3” which routes the preset on that MIDI channel to the selected submix bus.

In the screen below, MIDI channel 4 is programmed to the submix 1 bus. MIDI channels 2, 3 and 5 obey the submix routing as programmed in each voice.

The submix bus routines are also available at the Sub Output jacks on the rear panel. Note that these outputs contain only dry signal. The Effects Processors are connected to the Main Outputs ONLY.

O The dry signal is removed from the main output even if only one plug is inserted into a submix jack.

Individual Voices or MIDI channels can be routed to the four busses. Note that the signal lines represent stereo signals

If you insert a plug into a Sub Output jack, the dry signal from that bus is removed from the effects processor. This feature lets you have three dry mixes from the Sub Outputs and an “Effects Only” mix from the Main Outputs.

The Effects Sends

Because the amounts are Sends, we want to open the Main Send to Effect B, turn B->A up full and turn the Main Send to Effect A down to zero. This sends ALL of Effect B through Effect A.

Effect B Into Effect A

The output of effects processor B can be routed into effect processor A. This connects the effects in series instead of their normal parallel configuration. Two effects connected in sequence sound very different than the same two effects in parallel. For example, a chorus patched through reverb can turn a bland string section into a lush wall of sound. The B->A amount can also be controlled for even more flexibility.

v To Send the Output of Effect B through Effect A:

In this example, we send 100% of Effect B into Effect A.

1.Select the Effect A screen (in either the Master or Preset Edit menus).

2.Set the B->A Amount to 100%.

3.Turn the Send Amounts down to zero since we only want to hear the two effects in sequence.

4.Press the Next page button to select Effect B.

5.Select an effect and adjust the Main FX A Send percentage as desired.

6.Play the keyboard and you should hear the B Effect running through Effect A. This patch is shown below.

Three-way Effects Control

The effects processor controls are very flexible. The effects can be controlled in three different ways to suit your personal preference and to adapt to different situations.

1.Programmed as part of the preset when playing single presets (Omni or Poly Modes).

2.Programmed from the Master Effects Section when playing either single presets (preset Effect Type set to “Master”) or when in Multimode.

3.Programmed from the designated control preset when in Multimode.
