UltraTap Pedal Support

Audio I/O

A:

When in relay bypass, the input signal is hardwired to the output signal through relays so that the signal is unprocessed and does not go through the converters. There is an alternate setting for DSP bypass whereby the signal goes through the A/D and D/A.

A:

After extensive testing with an analog dry path vs. converting the signal and doing the wet/dry mix after the converter, we chose the latter due to the fact that it ultimately sounds better. By changing the wet/dry mix after the conversion we avoid comb filtering resulting from phase cancellation which occurs when mixing together a dry analog signal with a signal which has gone through A/D and D/A. This comb filtering effect can seriously degrade your tone depending on the frequency. We use very high-quality A/D converters which are very transparent and do not affect your tone (we have been making effects processors used by guitar players for 50 years and have a proven track record in this area). However, if you so desire, you can use a switcher or an analog pan pedal and run a completely dry analog signal path outside the stompbox and run the dot9 pedal at 100% wet. In fact, we have added several "Kill Dry" settings in the System Setup if you are running your rig that way.

A:

It may sound like the dot9 Pedals are adding brightness when Active (or in DSP Bypass) because the pedals are acting like a buffer. This is really letting you hear the highs that were lost from your signal without a buffer. Many amps have buffered effects loops to address this issue. In this case, we recommend that you connect our stompboxes through the effects loop of these amps. If your amp does not have an effects loop, or if you prefer to run our stompboxes in front of the amp (after the guitar but before the amp’s input,) a solution would be to always have a buffer pedal in the signal chain before the dot9 pedal (especially if using relay Bypass) or simply always use DSP Bypass mode.

Aux Switches

A:

No. When [TRIPLE AUX] is configured in System Settings, TIP = Increment Preset, RING = Decrement Preset and TIP + RING = Load Preset. When [EXP+AUX] is configured in System Settings, TIP = Expression Pedal and RING = TAP TEMPO.

A:

Yes. In the event you want to use a single button aux switch to control tap tempo, you need to set the pedal to “EXP+AUX” mode. Because tap tempo functionality is normalized to the ring plug on an insert cable, you can use a TRS to dual TS cable and just connect the ring end to a switch, however, having a dangling cable is not optimal. As an alternative, you can make a custom cable with a TRS plug on the stompbox end and a TS plug on the switch end. Wire it Tip to Ring and Sleeve to Sleeve, leaving Tip disconnected on the TRS side. Now, you have one neat cable for a single tap tempo switch.

 

A:

Yes. We recommend the Analog Endeavors Aux3. The Digitech FS3X is another good option. Make sure you connect your 3-button aux switch using a TRS cable and set the EXP Input Mode to TRIPLE AUX.

EDM

A:

Press and hold either the Shift, Control, Option, or Command keys, then click and drag the desired preset to the desired open preset slot.

A:

Once you successfully connect to EDM you will see the serial number of your pedal displayed in a box in the top right corner of EDM.

A:

Boot the pedal while pressing both the FREEZE button and FREEZE Footswitch to enter update mode. Connect the pedal to EDM via USB to mini B and install/reinstall the latest software: under “FIRMWARE UPDATES” click “Check for Updates” and install the latest available software which will be presented at the top of “Available Updates.” This should clear up any connectivity issues.

Expression Pedal

A:

In EXP+AUX mode, you can use an insert cable to connect an expression pedal and a tap tempo switch that is automatically mapped to control the dot9 pedal’s delay time. The Tip of the TRS plug should be connected to the expression pedal and the Ring of the TRS plug to the auxiliary switch. Please keep in mind that certain expression pedals that have TRS inputs will not work properly when connected with a single TS cable. For this mode, seek out TS expression pedals that have their pots wired as rheostats, where the wiper and reference voltage pins of the pot are wired to Tip and the ground end to Sleeve. In the event you only want to use the EXP input for tap tempo, you will again set the pedal to “EXP+AUX” mode. Because tap tempo functionality is normalized to the ring of the plug on an insert cable, you can use a TRS to dual TS cable and just connect the ring end to a switch, however, having a dangling cable is not optimal. As an alternative, you can make a custom cable with a TRS plug on the stompbox end and a TS plug on the switch end. Wire it Tip to Ring and Sleeve to Sleeve, leaving Tip disconnected on the TRS side. Now, you have one neat cable for a single tap tempo switch.

A:

Eventide recommends using an expression pedal with a resistance of 10kohms or higher. When in EXP mode it’s recommended to use a TRS cable for compatibility with a wider range of expression pedals.

A:

We recommend the Mission Engineering SP-H9 or any pedal that has a TS option. The DOD Mini Expression, Analog Endeavors Micro Expression Wheel and Line 6 EX-1 are also good options. Otherwise, using a regular TS connector on a pedal that normally takes a TRS, you’ll inadvertently tie the end terminals of the internal pot together exhibiting a 0-100-0 sweep range. Our dot9 Pedals won’t respond with an even tapered sweep as intended in this case.

A:

If your expression pedal has a trim pot control, try adjusting it to either end of its range. If your expression pedal causes parameter values to go from min to max and back down to min again as you move from toe to heel, try connecting it using a stereo phone (TRS) cable rather than a mono (TS) cable. If the calibration seems wrong, try plugging the expression pedal in before powering up the stompbox. Always connect the cable to your expression pedal first, then to the EXP input. Afterward, move the treadle back and forth, so that the dot9 pedal can automatically calibrate properly.

Firmware

A:

Boot the pedal while pressing both the FREEZE button and FREEZE Footswitch to enter update mode. Connect the pedal to EDM via USB to mini B and install/reinstall the latest software: under “FIRMWARE UPDATES” click “Check for Updates” and install the latest available software which will be presented at the top of “Available Updates.” This should clear up any connectivity issues.

General

A:

Yes. If you’re using a dot9 Pedal with a distortion pedal, we recommend that you connect it after the distortion pedal. In general, it’s best to place reverb or delays after distortion effects. That said, use whatever sequence works best for your sound.

A:

Yes! The dot9 family of pedals supports CV. Set the jack to EXP mode (which is the default). The limit is a max of 3.3V.

A:

While the algorithms are the same, there may be a slight perceptible variance in sound due to the different hardware architectures employed in the pedals.

A:

It sounds like you may be using a mono cable with the switch set for stereo. Make sure you’re wired correctly for stereo input (if that is what is indeed intended), and that the switch is set the correct way. Remember, the switch determines the input, not the output. For instance, if you’re simply trying to run stereo into two amps you should leave the switch in “Mono.” If something sounds funny, chances are, you may have the switch set incorrectly or be wired the wrong way.

A:

Because there is no digital I/O the sample rate is optimized for maximum audio performance for each effect and is program dependent.

MIDI

A:

Yes. Disaster Area Designs offers two 5-pin DIN to ¼” MIDI cables: The 5P-TRS or the 5P-QQ are both options.

A:

Yes. We recommend the Disaster Area Designs MIDI Box, the Chase Bliss MIDI Box, or the Meris MIDI I/O.

A:  

Set the Expression Pedal Jack to MIDI TRS in System Settings in order to daisy-chain to other MIDI over TRS-capable pedals. It should be noted that unlike the Space and H9 pedals, there is no MIDI Thru in this pedal platform. Thus, the dot9 Pedals will not work in a daisy-chain unless they are the last pedal in the line. 

A:

Yes. Simply connect a mini USB cable to the USB jack on the dot9 Pedal, no special settings are required to enable this. You can, however, set the MIDI Channel and enable the Midi clock as required.

Power Supply

A:

Eventide's own power supply provides the dot9 Pedals (Blackhole, MicroPitch Delay, and UltraTap) with 9VDC, 200mA with the center pin negative. We cannot recommend or judge the adequacy of power supplies which we have not tested. It is the responsibility of 3rd party manufacturers of power supplies to verify that their power supplies work with Eventide products if they wish to market them as doing so. Users may try non-recommended third party power supplies at their own risk. Using a non- regulated power supply that allows the voltage to reach 15VDC or more can cause damage to an Eventide stompbox - such damage is not covered under warranty. The only power bricks Eventide have tested and therefore can recommend are the PowerMax and PowerMini which carry a 5-year warranty and include the cables required to power Eventide stompboxes and the special mounting plate for PedalTrain pedalboards.

A:

9V DC, 200mA, Center Pin (-).

Presets

A:

Yes. Presets can be stored to and retrieved via EDM.

A:

To restore factory presets and all system settings, Boot pressing ACTIVE Footswitch & ACTIVE button. You can also perform a Factory Reset when connected to EDM. The Factory Reset option is located at the bottom of the “Manage Device” in the left-hand column of EDM. CAUTION: This function will overwrite any presets that you’ve saved. If you want to be able to restore one or more of your presets you must first save them to a computer.

A:

While only five presets can be accessed from the front panel, you can store 127 in its memory. You may use MIDI or the Eventide Device Manager to access all presets.

Registration

A:

To assist in the process of transferring a stompbox registration from the previous owner to you, we have created this set of instructions.

USB

A:

A few things. First, the USB interface is MIDI class-compliant for use with your computer sequencer or DAW. The USB interface can also be used to load software upgrades as they become available; dump your presets and load new presets via EDM. Finally, the USB port can also be used to connect to any MIDI controller or device that has MIDI host capabilities allowing MIDI control over the dot9 Pedals (Blackhole, MicroPitch Delay, and UltraTap) instead of using MIDI over TRS.
