6.2. Routing

Routing Edit Mode adjusts the routing of the currently loaded Program.

The H90’s two Presets can be routed to process your signal in series or parallel for each Program. This is useful for a variety of applications:

• If your Program uses a Distortion and Wah Wah Preset you may want to process the distortion in series with the wah wah, meaning your audio is first processed by the distortion, and then the distorted signal is processed by the wah wah.

• Alternatively, if you are using a Program with Delay and Reverb Presets, you can process your audio through these two Presets in a parallel path, meaning the audio is sent to the delay and reverb simultaneously on two paths, and your delay and reverb sounds will not affect each other.

The Routing Edit Mode appears in one of two ways, depending on whether the Global Routing Configuration is set to Insert or Dual on the System Menu's Global page (Section 7.1).

Fig. 6.4 Configure your Global Routing in the System Menu page.

Note

Changing your routing from Insert to Dual will automatically enable an alternate set of available Lists as well as your current Playlist. Programs and Lists that are created with Insert routing cannot be used with Dual routing, and vice versa.

Use H90 Control to convert the routing mode of your Programs and Lists by exporting and reimporting them. For example, export a Program or List that was created in Insert Mode, switch your H90 to Dual Mode, and then import that Program or List. H90 Control will prompt you to convert the Program or List to Dual Mode.

Press the Routing Button to enter Routing Edit Mode. Press any Footswitch to exit.

Pressing the P, A, or B LED Buttons will toggle active/bypass for the Program, Preset A, or Preset B.

Tip

When using Insert or Dual routing, press Quick Knob 1 to swap Presets A and B.

6.2.1. Insert Routing

The Insert Routing configuration allows Routing Mode to enable either two mono Inserts or one stereo Insert, which can be placed at any point along the signal path or turned off.

Insert Routing Options
Series	Parallel
Pre A	Pre A & B
Parallel	Pre A
Mid	Pre B
Post B	Parallel
	Post A
	Post B
	Post A & B

To enable an Insert:

• Quick Knob 1: Turn to change the routing between series and parallel.

  Note

  Programs with Presets routed in series will display in the top right corner.

  

  Fig. 6.5 Programs with Presets routed in series

  Programs with Presets routed in parallel will display in the top right corner.

• Quick Knob 2: Turn to enable Insert 1 and adjust the Insert position. Press to active/bypass Insert 1.

• Quick Knob 3: Turn to enable Insert 2 and adjust the Insert position. Press to active/bypass Insert 2.

Fig. 6.10 Inserts 1 & 2 routed in Parallel with Preset A & B

Fig. 6.11 Inserts 1 & 2 in Parallel, with Insert 1 pre-Preset A, and Insert 2 post-Preset A

Turning Quick Knob 3 completely clockwise will enable stereo insert 1-2, the position of which can then be adjusted using Quick Knob 2.

Each Insert has its own set of parameters: Send Level, Return Level, Mix %, Tails, Latency (from 0 samples to 512 samples), and Polarity (Normal/Inverted). Press the Routing Button or turn the Select Knob to scroll through the parameters.

Fig. 6.14 Page 2 of the Insert parameters

Turn Tails on to allow the inserted device’s effects to trail off naturally when bypassed. Turn Tails off to mute the insert immediately when bypassed.

Latency Configuration

Latency only should be set when inserting digital devices. Analog devices do not have appreciable latency. Setting the latency properly will prevent comb filtering for the inserted effect. Consult the inserted device’s documentation for its latency specifications.

To set the latency for an Insert:

• Invert the polarity.

• Set the mix to 50%.

• Bypass the external digital effect or adjust any mix knob so you only hear the dry signal.

• Adjust latency from 0 samples until the signal is silent or as quiet as possible.

• Disengage the polarity invert.

• When using an Eventide H9, set the insert latency to 109 samples.

Note

The H90 will automatically adjust to process audio in mono or stereo depending on the physical input and output connections. Insert routing will sum or mult the signal accordingly.

When using Stereo I/O:

• A mono insert at the end of the signal path will sum your output to dual mono.

• A mono insert in parallel to the H90’s presets, the output will remain in stereo.

When using mono I/O:

• A stereo insert will mult the signal path to stereo, but the H90’s presets will sum that signal back to mono.

6.2.2. Dual Routing

Dual Routing allows you to route two processing paths within your H90. This can be used to process two instruments separately through two different Presets, or to connect to an amplifier in a Pre/Post configuration using one Preset in your preamp section and one Preset in your amp’s effects return.

Note

Programs using Dual Routing will display in the top right corner.

Fig. 6.15 Programs using Dual Routing

• Turn Quick Knob 1 to change the routing position for Presets A and B on Paths 1 and 2.

• Quick Knob 2 and 3 are non-functional when Routing Mode is in Dual Routing configuration.

• Dual Routing enables two separate signal paths:

  • Path 1: Inputs 1/2 to Outputs 1/2

  • Path 2: Inputs 3/4 to Outputs 3/4

Dual Routing Positions
Routing	Path 1	Path 2
Path 1 Series	Series	Thru
Path 1 Parallel	Parallel	Thru
Pre/Post	Preset A	Preset B
Path 2 Parallel	Thru	Parallel
Path 2 Series	Thru	Series
