Rewind Leap Series Programmable Stereo Echo Guitar Effects Pedal

ABOUT ALEXANDER PEDALS
Alexander Pedals builds hand-crafted effects pedals in Garner, North Carolina. Each Alexander Pedal is meticulously voiced and tweaked by our sonic scientists to achieve sounds that are both instantly familiar yet completely unique.
Alexander Pedals are designed by Matthew Farrow and a group of trusted players, builders, and friends.
Matthew has been building guitar pedals since the late 1990s, first with Pharaoh Amplifiers, and now with Disaster Area Designs. Matthew has designed some of the most innovative effects units on the market, including some big names he’s not allowed to tell you about.
Alexander Pedals was started for two reasons – to make great tones, and to do good. The great tones part you probably have some idea about. As for doing good, Alexander Pedals donates a portion of the profits from every pedal sold to charity, whether you buy from us or our dealers. Matthew’s younger brother Alex passed away in 1987 of a form of cancer called neuroblastoma. Alexander Pedals honors his memory by helping in the fight to end childhood cancer.

BASIC OPERATION

It’s time to rediscover your affinity for trippy reverse reflections, washed- out reverberations and crystal-clear repeats. The Alexander Pedals Rewind is a reimagining of our flagship delay platform. Ten rejuvenated delay types, all the under-the-hood functionality you require, and an OLED display for instant recall of every parameter. Record, Repeat — Rewind.

Using the pedal is pretty simple:
Plug your instrument into the INPUT jack and your amplifier or other effect into the L jack.
Power up the pedal with 9V 250mA or more.
Turn some knobs. As soon as you touch a knob, the display will change to show what is happening. Hold the right foot switch (BYPASS / PRESET) to advance to the next preset, we’ve loaded some cool sounds on here for you to try out.

The lower-right knob has a pushbutton switch, tap that to  access extra parameters on the back pages of the userinterface.
We’ve put the most common controls up front, tweaking stuff on page 2, and utility items on page 3.
Three small boxes at the bottom of the display indicate the currently selected page.
That’s pretty much it. The rest of this manual covers advanced topics and fine details. If you run into any issues, we’ve got support info at the link below.
Have fun!

This manual contains full technical details on the operation of this pedal.

CONTROLS & DISPLAY

Your Leap Series pedal is pretty complex under the hood, but we worked hard to make sure that it’s easy to drive.
We combined a simple user interface with a high-contrast OLED display to get you the maximum tweakability with the minimum frustration. Just turn the knobs, it acts like pretty much every other pedal.
The lower right knob is equipped with push switch. Tap this knob to switch the display page, as indicated by the three small boxes at the bottom of the display. We’ll refer to this knob + button as the Page knob throughout this manual.
Hold the Page knob to access the Setup (page 7) and Preset Save (page 6) menus.

INS & OUTS

We’ve equipped every Leap Series pedal with a plethora of pluggable ports, to allow you lots of flexibility in your pedalboard routing.
We’ll cover the stereo routing stuff in full detail under Stereo Routing (page 11), but if you’re running in mono just use the input and L output jacks.

INPUT:| Instrument input.  Defaults to mono, may be set to TRS Stereo or TRS Sum using the Setup menu.
---|---
RIGHT:| Right stereo output.  This output may be phase-inverted in the Setup menu to match the output phase of your amplifiers.
FIRMWARE UPDATE
LEFT / TRS:| Main output.  Use this as the main output for mono setups, or the left output for stereo.
May also be used as a TRS stereo output (disables the RIGHT jack) if the next effect or input is TRS stereo.
MULTI:| User configurable jack, used for Expression pedal (TRS only,) remote foot switch, or MIDI input / output (requires converter unit or adapter cable.)

DC 9V:| Center-negative, 2.1mm ID barrel jack for DC input.  The pedal requires a minimum of 250mA to operate, higher current supplies are acceptable.  Do not power the pedal from a source greater than 9.6V DC.
---|---
USB:| USB mini-B connector for USB MIDI or firmware updates

BYPASS & TRAILS

Leap Series pedals feature a buffered bypass system designed to keep your signal as clean as possible at all times. The dry signal passes through the digital signal processor in order to maintain phase coherence between wet and dry.
We offer three bypass modes, selectable with the TRAILS item in the Setup menu.

OFF: The wet signal is cut off immediately upon entering bypass
ON: The wet signal delay / reverb trails are allowed to ring out in bypass
AUTO: The wet signal delay / reverb trails are allowed to ring out but automatically fade out after 10 seconds to eliminate noise in bypass Rewind has ten selectable sound modes, each based on a different reverb effect type. You can tweak these modes to your taste, and you can save any sound to any preset. To change sound modes, turn the lower right knob on page 1. Tap the lower right knob to advance to the next page.

The following controls are common to all modes on page 3:
DIV – tap division for modulation or delay, not available in DYNAMIC or PITCH modes
LEVL – overall volume for the pedal (wet + dry)
RAMP – Ramp rate, lower settings ramp faster
TRIG – Ramp trigger mode, please see Expression and Ramping for details

PRESETS

How do you make quick changes on a pedal that has 12+ knobs? PRESETS. Every Leap Series pedal
allows you to save up to 32 presets that contain the entire state of the pedal.
Loading a preset recalls all knob positions, sound modes, and expression pedal mappings.
To load a preset, hold the BYPASS / PRESET foot switch. You can set the number of available presets in the Setup Menu, from 1 to 8. You can also set the pedal to access the upper banks of presets (9-16, 17-24, 25-32) in the same menu. This allows you to use multiple banks of presets for different gigs, bands, instruments, whatever you like.
Hold both footswitches to scroll back to the previous preset.
If eight presets per bank isn’t enough, you can enable a double-bank of 16 presets by setting PRESET = 1-16 or 17-32.
You can also use an external MIDI controller to load any preset from 1-32, regardless of how the Setup Menu is configured.
To save a preset, first use the pedal knobs to tweak the sound, then hold the Page knob.
Press and hold the BYPASS / PRESET foot switch to enter the save menu.
If you want to save to the current preset, you can just hold down the BYPASS /PRESET foot switch again. If you prefer to rename the preset, turn the lower left knob to select a character in the name and turn the Page knob to edit that character. You can also change the save location by highlighting the preset number then turning the Page knob.
Press and hold the BYPASS / PRESET foot switch to save, or hold the TAP / CTRL foot switch to cancel the save.

SETUP MENU

To enter the Setup menu, first hold down the PAGE / MENU knob (lower right,) then hold the left foot switch.
Turn the lower left knob to scroll through the available parameters, then turn the lower right knob to set its value.
Hold the PAGE / MENU knob (lower right) to save your settings and exit the menu.

EXPRESSION PEDAL

Connect a TRS expression pedal to the MultiJack to control any or all of the pedal parameters remotely. Enter the Setup menu and configure M.JACK = EXPRESSN, then save and exit.
Leap Series pedals requires a TRS expression pedal, sleeve = 0V (common,) ring = 3.3V, tip =0-3.3V. You can also use an external control voltage (CV) connected to tip and sleeve, as long as it doesn’t exceed 3.3V.
If you’re using a MIDI controller, you can send MIDI CC 100, value 0-127. 0 is the same as full heel setting, 127 is toe setting.
To map expression pedal values to pedal settings, first set the expression pedal to the heel setting then turn the pedal knobs. Then sweep the expression pedal to the toe setting and turn the knobs again.

Your Leap Series pedal will smoothly blend between the two knob settings as you move the expression pedal. You can map any of the effect knobs to the expression pedal, other than a few controls that don’t have linear functions like tap division and ramp settings.
If you prefer to have controls that aren’t affected by the expression pedal, simply set them with the pedal heel down, then gently “wiggle” the knob with the pedal at toe down. This will set the same values for heel and toe and those knobs won’t change as you sweep the pedal. You can also use the Ramp Clear function to clear the expression pedal settings, as described on the next page.
The MultiJack input is factory-calibrated for most common expression pedal types, but you can also adjust the range using the Setup menu. Sweep the pedal to the heel position and then set the EXP LO value to match the number shown in the box on the display next to it.
Repeat for the EXP HI value and then save.

RAMPING

If you’re not into using an expression pedal, that’s okay – the Leap Series pedals feature a built-in expression control function called RAMP.
Imagine the Ramp as an automatic expression pedal that you trigger from a foot switch.
Hold the Tap / Ramp foot switch to fire the ramp, and the pedal will smoothly move between expression pedal settings by itself.
Use the RAMP knob to set the speed of the ramp, and the TRIG knob to set the trigger mode.
TOGG ramp will alternate between positions when you hold the foot switch MOM ramp will move from heel to toe when you hold the foot switch, and return when you release it.
CLR* resets the ramp and expression parameters. Select this option, then fire the ramp using the Tap / Ramp foot switch copy the “heel” values to the “toe” values and clear the expression settings. The ramp trigger will then return to TOGG mode.

REMOTE FOOT SWITCH

You can also connect a standard momentary normally-open foot switch to the MultiJack to remotely control the Tap / Ramp functions.
Enter the Setup menu and configure M.JACK = FT.SW, then save and exit.
Tap the remote foot switch to set the tap tempo rate, hold to trigger the ramp. The remote foot switch will duplicate the functions of the built-in left foot switch.

EXPANDER SWITCH

All Leap Series pedals support the ALEXPANDER triple foot switch for preset selection or scrolling.
Connect your ALEXPANDER to the MultiJack using a standard TRS / stereo cable, then enter the Setup menu and configure M.JACK = PRST.EX or SCRL.EX. Save and exit.
In PRST.EX mode, the three buttons of the ALEXPANDER directly select presets 1, 2, and 3 with a single tap. You can still use the footswitches on the pedal itself to access any other presets in your currently selected bank.
In SCRL.EX mode, the A and C (left and right) buttons of the ALEXPANDER will scroll through all 32 presets in order. Tap the B (center) button to enter SEARCH MODE, which will scroll through the presets without activating them. When you arrive at your desired preset, tap the B (center) button again to load that preset and exit SEARCH.

TAP TEMPO AND MIDI CLOCK

Leap Series pedals support Tap Tempo for the modulation LFO or the delay time. The pedal will always prioritize the delay time for sound modes that have both LFO and delay.
Tap the TAP / CTRL (left) footswitch once to begin the Tap Tempo function. The display will show TAP and a timeout bar in the lower left corner to indicate that the pedal is waiting for a second tap.

Tap the TAP / CTRL (left) footswitch a second time to set the tempo and end the Tap Tempo function.
If you don’t tap a second time before the timeout bar resets, the tempo will remain at the previously set value.

The DIV parameter on PG3 of the display sets the tap tempo subdivision.
TRP: time subdivides to eighth-note triplet (3x tap speed)
8TH: time subdivides to eighth-note (2x tap speed)
DOT: time subdivides to dotted eighth-note (1.5x tap speed)
QTR: time is not subdivided, quarter-note (1x tap speed)
NCLK: time is not subdivied, quarter note, MIDI CLOCK is ignored

The pedal will use the most recent tempo adjustment, so if you tap tempo and then turn the Time or Rate knob the tapped tempo will be cancelled and set to the knob value.
If you tap in a tempo and then save the preset, the saved time will use the tempo and the subdivision as set by the DIV knob.
If you use the time or rate knob to set the tempo, it may load with a different tempo unless DIV is set to QTR or NCLK. If you mostly plan to use the pedal knobs to set the tempo, we recommend using the QTR or NCLK setting for DIV.
Leap Series pedals also sync to incoming MIDI clock over the MultiJack or USB. MIDI clock will override all other tempo sources including Tap Tempo and the pedal knobs, unless DIV is set to NCLK in which case the pedal will ignore MIDI clock entirely.
The DIV setting is saved for each preset, so you can use any division on any preset based on your musical needs.
Your Leap Series pedal supports two different tempo modes, set by the TEMPO item in the Setup menu.

PRESET: Each preset loads with its saved tempo and division
GLOBAL: All presets load with the same master tempo but will subdivide based on DIV settings in preset.
Presets saved with DIV = NCLK will always load with their saved tempo, even if the pedal is set to GLOBAL tap tempo. This is useful for dialing in slap echo when in GLOBAL tempo mode.
You can also select from several tempo display options by adjusting the TIME.D item in the Setup menu.
BAR: Time displays as bar graph
BPM: Time displays in beats per minute
MS: Time displays in milliseconds

STEREO ROUTING

Every Leap Series pedal is designed to work in a stereo context, but also shines in mono.
We’ll cover how all the various stereo modes work so you can pick the one that works best with your rig.
To set the stereo mode, enter the Setup menu and navigate to STEREO. The pedal will reconfigure its inputs and outputs as you step through the menu, and once you’ve set it as you like just hold the PAGE knob to save.
We also allow you to change the phase of the R output to correct issues with the phase of your amplifiers or other effects. Try setting R.PHASE to both options, the one with more low end is usually correct.

Standard mono input.
Use this for mono input with full stereo output
Use the L output for mono.

Input is summed L+R from TRS, output is full stereo.
Use this if you play in mono but have stereo effects before the Leap Series pedal.

Input is stereo from TRS, output is full stereo.
Use this if the previous device in chain has stereo output.

MIDI SETUP

The MultiJack can also act as a MIDI interface, to allow full remote control of your Leap Series pedal.
Enter the Setup menu and configure M.JACK = MIDI, then set CHANNL = your desired MIDI channel. Save and exit.
You can then connect your Leap Series pedal to your MIDI controller or other device using the MultiJack.
We recommend the use of an active MIDI converter such as the Disaster Area MIDI Box 4.

The MultiJack is also compatible with many devices using a passive MIDI to TRS cable.
We recommend the Disaster Area 5P-TRS PRO but most TRS type-A cables should work so long as pin 2 is earthed at the MIDI controller output. Please note that some MIDI controllers do not support the use of a passive MIDI to TRS cable, consult your controller manufacturer.
The MultiJack is wired using Tip = Current Sink, Sleeve = Ground / Common.
NOTE: In some cases, MIDI interference can occur if the TRS ring is left floating. We recommend you set MIDOUT to OFF or USB, this disables the ring connection and will prevent MIDI echoes.

MIDI COMMANDS

Your Leap Series pedal features full and comprehensive MIDI implementation. Every single function and knob may be controlled by MIDI.
Each MIDI command controls the knob or function as described below. Please consult the Sound Modes (page 4-5) section to match each knob position to the relevant control.
Leap Series pedals will sync to incoming MIDI clock messages for any modes that have the DIV knob on the last page of the display. The pedal will subdivide incoming clock as set by DIV, or set DIV to NCLK to force the pedal to ignore incoming clock. This setting is saved perpreset.
Please consult the Tap Tempo and MIDI Clock section on page10 for details.
