After you log in, register your unit\u2019s serial number.<\/p>\n\n\n\n<p>From your account page, download the <strong>H90 Control<\/strong> app for Windows or macOS. We\u2019ll discuss its use at the end of this guide.<\/p>\n\n\n\n<h2 id=\"Setup-and-Connections\">Setup and Connections<\/h2>\n\n\n\n<p>Power up the H90 by plugging in the 12V power supply provided with the unit. There is no on\/off switch.<\/p>\n\n\n\n<h3 id=\"Eventide-H90-back-panel-connections\">Eventide H90 back panel connections<\/h3>\n\n\n\n<p>The back panel provides:<\/p>\n\n\n\n<ul><li>Four input jacks and four output jacks that accept standard mono (unbalanced) \u00bc&#8221; plugs. The inputs and outputs can be configured for <a href=\"https:\/\/www.sweetwater.com\/insync\/instrument-level\/\">Instrument Level<\/a> (such as a guitar) or <a href=\"https:\/\/www.sweetwater.com\/insync\/line-level\/\">Line Level<\/a>. The eight LEDs on the back will light up to indicate which inputs and outputs are set for Line Level.<\/li><li>Two <strong>EXP\/CTL<\/strong> jacks for connecting <a href=\"https:\/\/www.sweetwater.com\/insync\/using-expression-pedal-guitar-effects\/\">expression pedals<\/a> or aux footswitches with TRS connectors<\/li><li>One USB-C port for connecting to a Windows PC or Mac to use the <strong>Eventide H90 Control<\/strong> app and send and receive MIDI controls<\/li><\/ul>\n\n\n\n<p>The side panel provides 5-pin DIN connectors for <a href=\"https:\/\/www.sweetwater.com\/c513--Foot__and__Pedalboard_MIDI_Controllers\">MIDI controllers<\/a>.<\/p>\n\n\n\n<h3 id=\"Eventide-H90-inputs,-outputs,-and-routing\">Eventide H90 inputs, outputs, and routing<\/h3>\n\n\n\n<p>The four audio inputs and four outputs provide extensive configuration options.<\/p>\n\n\n\n<p><strong>Insert Routing<\/strong> is enabled by default. We will use this to get started.<\/p>\n\n\n\n<p>Under <strong>System<\/strong> settings, you can also set up <strong>Dual Routing<\/strong>, setting up the H90 as two independent mono or stereo effects processors. Different jacks can be configured for inputs, sends, or returns depending on the mode.<\/p>\n\n\n\n<p>You can set up two independent stereo signal paths, and you can even set up the H90 to process guitar and vocals on separate channels if you hook up a <a href=\"https:\/\/www.sweetwater.com\/store\/detail\/MixingLink--eventide-mixing-link-preamp-and-fx-loop\">preamp for the vocal mic<\/a>. For guitar, you can also set up <strong>Dual Routing<\/strong> for the <a href=\"https:\/\/www.sweetwater.com\/insync\/what-is-the-4-cable-method-for-connecting-an-amp-to-a-multi-effects\/\">four-cable method<\/a> or <a href=\"https:\/\/www.sweetwater.com\/insync\/guitarists-guide-electric-guitar-amps-part-3\/\">pre\/post in an amp effects loop<\/a>.

Connect a guitar directly to <strong>Input 1<\/strong> and connect <strong>Output 1<\/strong> to an amp. If you want to hear the effects in stereo, hook up <strong>Output 2<\/strong> to a second amp; the H90 will automatically set the effects to stereo mode. Now we can navigate the front panel and begin to work with the sounds.<\/p>\n\n\n\n<h2 id=\"Sounds-and-Settings\">Sounds and Settings<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"850\" src=\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram-1024x850.jpg\" alt=\"\" class=\"wp-image-1775665\" srcset=\"https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram-1024x850.jpg 1024w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram-300x249.jpg 300w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram-768x637.jpg 768w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram-1536x1275.jpg 1536w, https:\/\/www.sweetwater.com\/sweetcare\/media\/2022\/11\/H90-Knob-Diagram.jpg 1836w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 id=\"Selecting-and-editing-programs\">Selecting and editing programs<\/h3>\n\n\n\n<p>Each <strong>Program<\/strong> on the H90 consists of two <strong>Presets<\/strong> labeled <strong>A<\/strong> and <strong>B<\/strong>. <strong>Programs<\/strong> can be saved into <strong>Playlists<\/strong>.&nbsp;<\/p>\n\n\n\n<p>To choose a <strong>Program<\/strong>, turn the <strong>Select <\/strong>knob to scroll through the active <strong>Playlist<\/strong>. Press the knob to activate that <strong>Program<\/strong>. You can also page through the <strong>Programs<\/strong> by using the <strong>A<\/strong> and <strong>B<\/strong> footswitches and tapping the <strong>Active<\/strong> footswitch to activate the <strong>Program<\/strong>.<\/p>\n\n\n\n<h3 id=\"Filtering-programs-by-category\">Filtering programs by category<\/h3>\n\n\n\n<p>You can zero in on the type of effect you want by pressing the <strong>Program<\/strong> button again and using the categories above the three <strong>Quick Knobs<\/strong>. The display will show <strong>List<\/strong>, <strong>Type<\/strong>, and <strong>Algorithm<\/strong>. Use these to narrow down your choices. For example:<\/p>\n\n\n\n<ul><li>Turn the first knob under <strong>List<\/strong> to select <strong>Lead<\/strong> sounds.<\/li><li>Under <strong>Type<\/strong>, select <strong>Modulation<\/strong>.<\/li><li>Then turn the knob under <strong>Algorithm<\/strong>, and from the 62 effects algorithms in the unit, you will see the list of those that pertain to <strong>Lead<\/strong> and <strong>Modulation<\/strong> sounds.<\/li><li>Turn the <strong>Select<\/strong> knob, and you will only be shown the shorter list of effects in those categories.<\/li><li>Press the <strong>Select<\/strong> knob again to activate the <strong>Program<\/strong>.&nbsp;<\/li><\/ul>\n\n\n\n<h3>Using Quick Knobs to adjust parameters<\/h3>\n\n\n\n<p>The three<strong> Quick Knobs<\/strong> give you access to the three parameters most helpful to adjust in a live setting, depending on which <strong>Program<\/strong> you selected. (Each <strong>Program<\/strong> has many more parameters you can access through deeper editing.) You\u2019ll see three settings labeled <strong>A<\/strong>. Turn each knob to adjust these parameters on the <strong>A Effect<\/strong>. Tap one of the <strong>Quick Knobs<\/strong> again to toggle to the three settings for the <strong>B Effect<\/strong>.<\/p>\n\n\n\n<h3>Change the Effects in a Program<\/h3>\n\n\n\n<p>You can choose a different <strong>Effect<\/strong> to be a part of your <strong>Program.<\/strong><\/p>\n\n\n\n<ul><li>Press the <strong>Presets<\/strong> button.<\/li><li>Toggle between <strong>A<\/strong> and <strong>B<\/strong> and turn the <strong>Select<\/strong> knob to find another <strong>Effect<\/strong>.<\/li><li>Tap <strong>Program<\/strong> again to activate it.<\/li><li>Press the LED buttons above the <strong>A<\/strong> and <strong>B<\/strong> footswitches to engage or bypass the <strong>A<\/strong> <strong>Effect<\/strong> and the <strong>B<\/strong> <strong>Effect<\/strong> independently.<\/li><\/ul>\n\n\n\n<p>Once you have selected an <strong>Effect<\/strong>, you can customize it.<\/p>\n\n\n\n<ul><li>Press the <strong>Parameters<\/strong> button.<\/li><li>Scroll through each page of three parameters using the <strong>Select<\/strong> knob.<\/li><li>Adjust each parameter with the <strong>Quick Knobs<\/strong>.<\/li><\/ul>\n\n\n\n<h3 id=\"Hot-Knob\">Hot Knob<\/h3>\n\n\n\n<p>In this mode, the display shows <strong>HK<\/strong> next to the <strong>Perform<\/strong> knob. This is the <strong>Hot Knob<\/strong> function. You can assign one parameter in the <strong>Program<\/strong> as the <strong>Hot Knob<\/strong> to quickly adjust it with the <strong>Perform<\/strong> knob.<\/p>\n\n\n\n<h3 id=\"Setting-Tempo-for-time-based-effects\">Setting Tempo for time-based effects<\/h3>\n\n\n\n<p>Press the <strong>Presets<\/strong> and <strong>Parameters<\/strong> buttons together to enter <strong>Tempo<\/strong> mode. Set the <strong>Tempo<\/strong> in beats per minute (bpm) using the left <strong>Quick Knob<\/strong>. With the middle <strong>Quick Knob<\/strong>, you can set the clock source to <strong>Program<\/strong> or <strong>Global<\/strong>.<\/p>\n\n\n\n<p>When you select one of these, the <strong>P Active<\/strong> button flashes, and you can set a<strong> tap tempo<\/strong> with the <strong>P footswitch<\/strong>. You can also set <strong>Source<\/strong> to <strong>MIDI Clock<\/strong> for external control over USB or MIDI cables, which bypasses the internal tempo settings. Press the <strong>Perform<\/strong> knob again to exit this mode.<\/p>\n\n\n\n<h3 id=\"Hot-Switches\">Hot Switches<\/h3>\n\n\n\n<p>Tap the <strong>Perform <\/strong>knob again. The display will show <strong>Hot Switch<\/strong> assignments for the three footswitches on board. You can assign <strong>Program<\/strong> parameters to the footswitches. You can also assign <strong>Hot Switch<\/strong> parameters to external aux footswitch controllers with deeper editing.<\/p>\n\n\n\n<h3 id=\"Bank-mode\">Bank mode<\/h3>\n\n\n\n<p>Press and hold the <strong>Select <\/strong>knob to enter <strong>Bank<\/strong> mode. This enables you to navigate the <strong>Playlist<\/strong> in <strong>Banks<\/strong> of three programs simultaneously. Pressing a footswitch activates a <strong>Program<\/strong>. Pressing the footswitch again bypasses it. Move between the <strong>Banks<\/strong> by pressing and holding the <strong>A footswitch <\/strong>(down) or the <strong>B footswitch<\/strong> (up).<\/p>\n\n\n\n<h3 id=\"Routing\">Routing<\/h3>\n\n\n\n<p>Press the <strong>Routing button<\/strong> to go into <strong>Routing<\/strong> <strong>mode<\/strong>. You can set the two <strong>Effects<\/strong> in a <strong>Program<\/strong> in <strong>Series<\/strong> or <strong>Parallel<\/strong> modes. As an advanced capability, if you are using either of two <strong>Inserts<\/strong>, you can position each <strong>Insert<\/strong> in different positions in the signal chain.<\/p>\n\n\n\n<p>By turning the <strong>Select<\/strong> knob, you will go to the second page, where you can set <strong>Send Level, Return Level,<\/strong> and <strong>Mix<\/strong> percentage for the <strong>Inserts<\/strong>.<\/p>\n\n\n\n<p>By turning the <strong>Select <\/strong>knob again, you will go to the third page, where you can set three parameters:<\/p>\n\n\n\n<ul><li><strong>Tails<\/strong>, on or off. This determines whether an <strong>Effect<\/strong> or <strong>Program<\/strong> continues to ring out when you disable an <strong>Insert<\/strong>.<\/li><li><strong>Latency<\/strong> and <strong>Polarity<\/strong> are used to correct phasing issues if you have configured the H90 with an external effects loop and are sending an output to external hardware and back again.<\/li><\/ul>\n\n\n\n<p>There are even more routing options if you use <strong>Dual Routing<\/strong> rather than <strong>Insert Routing<\/strong>.<\/p>\n\n\n\n<h3 id=\"System-settings\">System settings<\/h3>\n\n\n\n<p>Press the <strong>Programs<\/strong> and <strong>Routing <\/strong>buttons together to go into <strong>System<\/strong> settings. There are five areas.<\/p>\n\n\n\n<h4 id=\"Global\">Global<\/h4>\n\n\n\n<p>Under <strong>Global<\/strong>, you can designate which of four <strong>User Playlists<\/strong> is the master <strong>Playlist<\/strong> that you are working with. Under <strong>Routing<\/strong>, you can switch the H90 from <strong>Insert Routing<\/strong> to <strong>Dual Routing<\/strong>. Under <strong>Bypass<\/strong>, you can select whether the effects ring out when you bypass the unit or whether it switches off immediately.<\/p>\n\n\n\n<p>Turn the <strong>Select <\/strong>knob for the next page of parameters. You can set a <strong>Spillover Time<\/strong> in seconds, which is how long a <strong>Program<\/strong>\u2019s <strong>Effects<\/strong> will ring out after you switch to a new <strong>Program<\/strong>.<\/p>\n\n\n\n<p><strong>Source Type<\/strong> is an important setting, as it makes global changes that optimize the algorithms to the frequency range of the instrument you are playing. The <strong>Source Types<\/strong> are <strong>Guitar<\/strong>, <strong>Bass<\/strong> guitar, <strong>Lead<\/strong> (synthesizer), and <strong>Sub<\/strong> (bass synthesizer).<\/p>\n\n\n\n<p><strong>Kill Dry <\/strong>is a setting you need for <strong>Dual Routing<\/strong> mode.<\/p>\n\n\n\n<p>Press the <strong>Select<\/strong> knob to go back to the <strong>System<\/strong> menu.<\/p>\n\n\n\n<h4 id=\"I\/O\">I\/O<\/h4>\n\n\n\n<p>Select each of the four inputs and four outputs and set each for either <strong>Instrument level<\/strong> (guitar, bass) or<strong> Line level<\/strong> (for connecting synthesizers, preamps, or hooking up an audio interface). It is also where you set the two <strong>EXP\/CTL<\/strong> inputs to accept either an expression pedal or a set of three footswitches and where you can calibrate the range of expression pedals.<\/p>\n\n\n\n<h4 id=\"MIDI\">MIDI<\/h4>\n\n\n\n<p>Set MIDI channel parameters for external MIDI control, and also set them to transmit MIDI commands from the knobs, buttons, and switches of the H90.<\/p>\n\n\n\n<h4 id=\"Preferences\">Preferences<\/h4>\n\n\n\n<p>Raise or lower the H90\u2019s LED brightness.<\/p>\n\n\n\n<h4 id=\"About\">About<\/h4>\n\n\n\n<p>Displays the unit\u2019s serial number, the software (firmware) version, and the version of the Factory Pack, which is the set of presets provided by Eventide.<\/p>\n\n\n\n<h3 id=\"Built-in-Tuner\">Built-in Tuner<\/h3>\n\n\n\n<p>Finally, if you are in <strong>Perform<\/strong> mode and you depress the <strong>A and B footswitches<\/strong> simultaneously, you go into <strong>Tuner<\/strong> mode to tune your guitar. You can set the base pitch and whether the signal is muted while you tune or whether it passes through.<\/p>\n\n\n\n<h2 id=\"Reset-H90-Settings\">Reset H90 Settings<\/h2>\n\n\n\n<p>If your unit seems to be malfunctioning, or if you want to restore it to its default settings, there are two reset modes.<\/p>\n\n\n\n<ul><li><strong>Reset System Settings:<\/strong> Press and hold Quick Knob 1 while powering on, and continue holding until the on-screen message appears. This preserves user data.<\/li><li><strong>Factory Reset:<\/strong> Press and hold all three Quick Knobs while plugging in the power adapter. Continue holding until the on-screen message appears. This deletes all user data (Lists, Programs, Presets, System Settings and Tempo).<\/li><\/ul>\n\n\n\n<h2 id=\"Update-the-Eventide-H90-Firmware\">Update the Eventide H90 Firmware<\/h2>\n\n\n\n<p>It\u2019s a good idea to make sure your H90 is running the newest software update from Eventide.&nbsp;<\/p>\n\n\n\n<p>Use the included USB-C to USB-A cable to connect your H90 to your Windows PC or Mac. If your computer only has USB-C connectors, you will need a <a href=\"https:\/\/www.sweetwater.com\/store\/detail\/USBC-USBA--startech-usb-c-to-usb-a-adapter-6-inch-usb-3.0\">USB-A to USB-C adapter<\/a>, which is not included. You can also use a <a href=\"https:\/\/www.sweetwater.com\/store\/detail\/USB306CC--hosa-superspeed-usb3.1-gen2-usb-c-to-usb-c-cable\">USB-C to USB-C cable<\/a>.<\/p>\n\n\n\n<p>Launch the H90 Control app. In the upper-right-hand corner, click <strong>Add Device<\/strong>. Choose your pedal from the drop-down menu and click <strong>Add<\/strong>. Once your pedal is detected, click the <strong>Connect<\/strong> button. The app will connect to the internet and check for a firmware update. If you receive a Software Update message, follow the on-screen instructions, and the app will install the new firmware on your H90.<\/p>\n\n\n\n<h2 id=\"Eventide-H90-Control-App\">Eventide H90 Control App<\/h2>\n\n\n\n<p>The <strong>H90 Control<\/strong> app for Mac and Windows PC provides a user interface to program all the H90\u2019s parameters; to configure <strong>Inputs<\/strong>, <strong>Outputs<\/strong>, and signal routing; to manage <strong>Program<\/strong> and <strong>Preset<\/strong> settings; and to import and export <strong>User Lists<\/strong>.
