Z.Vex Vexter Super Seek Trem

This product is a far more advanced version of the original Seek Trem and Tremorama pedals. Basically the Super Seek Trem is a 16 step sequencer of volume pots. This allows you to do tremolo in complex rhythmic patterns impossible with standard tremolos. From automated volume swells, to extreme helicopter blade like square wave tremolo that gallops, to what sounds like traditional amp tremolo but is pulsing in a nine step pattern of triplets against your 4/4 groove… all locked to your Pro Tools Session! Polyrhythmic bliss! New features include: tap tempo, MIDI tempo control, glissando, expression pedal control over tempo and glissando, adjustable number of stages from 1 to 16, automatic tempo slowing or speeding (delta), savable/loadable presets and more!

Important Note: In order to accommodate all of the Super Seek Trem’s features, there are some instances where a knob may control more than one parameter. This is indicated on controls that have a slash in their label. For example: the 16 mini step knobs can be set to control either the “trem” for that individual step, or “groove” for that individual step. A mini toggle switch labeled “groove/trem” assigns the function of those 16 mini knobs. Another couple examples of this type of multi-function are the “tap div/delta” and “steps/preset” knobs. These are not your father’s knobs! They are rotary encoders, kind of a cross between a knob and a switch. They can turn like regular knobs, they can be pushed down and turned, they can be pushed down and held, and they can be pushed and released. The parameter to the left of the slash is controlled by turning the knob normally. The parameter to the right of the slash is controlled by pushing down the knob and turning it while depressed. We’ll cover all of that specifically later.

If you’ve used a Ringtone before you’ll see the familiar Step/ Seq /Rnd mini toggle switch on the upper left. Seq and Rnd are modes where the pedal’s brain moves you from step to step, either sequentially or randomly. Step mode allows you to advance from step to step manually by tapping on the “tap/hold” button.


  • Speed Control: There are four different ways to control tempo. The “speed” knob, the “tap/hold button”, MIDI clock input (from a computer or other MIDI device), and the expression pedal input (a 1/4” standard TRS synth-type expression pedal). You’ll see quickly that adjusting the speed control overrides the previous tap tempo setting, tapping then overrides the previous speed control setting, and MIDI overrides all.
  • Adjusting the Groove Sequence: If you wish, you can individually change the rate at which each step moves to the next, causing less of a sudden step and more of a glide to the next step in the sequence. Set the “groove/trem” switch to “groove” to access this feature.
  • Adjusting the Glissando Globally: There’s a knob on the upper right labeled “gliss” which globally adjusts all glissando rates between steps to the same value. It’s labeled differently from the “groove” switch to remind you that it adjusts all of them at once, so it’s not quite as “groovy.” ADJUST THIS ONE FIRST. If you adjust the individual groove settings and then try to adjust the global glissando setting, it will erase all of the groove settings and every step will follow the global glissando control alone. You can, of course, go back and set your groove settings, but remember this to save yourself time and aggroovation… set the glissando first, then get groovy, baby.
  • Delta Control: Z.Vex came up with this mode where the tempo can speed up and slow down, and the rate at which that happens called DELTA. To activate DELTA mode, push and release both the “tap div/delta” and “steps/preset” knobs at the same time. Each push moves the mode led next to the “tap/hold” button. Stop when you get to delta. When the “tap div/delta” knob is held down and turned, it adjusts the delta rate. This controls the rate of change when the pedal is speeding up or slowing down. Selecting the little arrow pointing left on the mini toggle switch causes the tempo to decelerate when you step on the “tap/hold” button. When you release that button, the speed snaps back to the original tempo. Fun, huh? If you choose the little arrow pointing right then press and hold the “tap/hold” button, it speeds up until you let go of the “tap/hold” button. Then it again snaps back to the original tempo.
  • Speed Knob: Set as you like
  • Tap Tempo: Tap Tempo has become a fairly common way to manually enter tempos into time based pedals like delays, tremolos, etc. The Super Seek Trem powers up in Tap Tempo mode. Tap Tempo captures and uses the time between your last 2 taps as a foundational pulse. From there, you turn the “tap div/delta” knob normally (without pushing) to select how many steps the sequencer travels in between tap pulses.
  • MIDI Controlled Tempo: The Super Seek Trem may be clocked by any device that outputs MIDI clock information. It considers only the clock portion of MIDI data. MIDI clock will take priority over the speed knob, tap tempo, and expression pedal controls. If the MIDI clock is stopped at any time, the sequencing will freeze until you tap in a new tempo, turn the speed control, or MIDI clocking resumes. The “tap div” control applies to MIDI clock similarly to tapped tempos.
  • Number of Steps: The “steps/preset” knob allows you to choose how many total steps are in your sequence. Turn the knob without pushing to select how many steps before the sequence starts over. You can select any number from 1 to 16.
  • Adjusting the Trem Sequence: Adjusting the individual sequence controls (there are 16 of them) will change the wah sounds when the “groove/trem” mini toggle switch on the right hand side of the pedal switch is set on “trem”.
  • Hold: When the “tap div/delta” and “steps/preset” knobs are pushed simultaneously for a moment, you can change the function of the “tap/hold” switch and select HOLD mode. In this mode, the sequencing stops when you push and hold the “tap/hold” switch, and continues when you let go. This feature works with MIDI clocking and all other tempo choices.
  • Go To 1: This is another function of the “tap/hold” button. Whenever you want the sequence to go directly to 1 and collect $200, tap the “tap/hold” switch ONCE. You have to be in TAP TEMPO mode (to get there, push and release both the “tap div/delta” and “steps/preset” knobs to cycle through the modes). Important Note: this is a really cool trick, but if you tap too close together you will wind up entering a new tempo. Using this feature with MIDI is really fun, and you don’t have to worry about tapping too often. You can interrupt your sequence at any time, and jump back to the beginning. This allows you change the sensation of your sequence by moving the apparent start point. You can also stutter the beginning of your sequence to complicate the pattern.

Battery & Power Supply

We highly recommend that you use a high-quality 9VDC power supply with your Super Seek Trem with at least 100mA capability. It should have a center-negative BOSS type barrel connector. The pedal can operate using a 9V battery but do not expect much battery life… this thing is a power hog because of all of the LEDs and the micro controller.
