    USB. Please be aware that the USB jack alone cannot reliably power your Zendrum. If you need to send power to your Zendrum through the MIDI IN jack, then you’ll need to use the DC adaptor to provide the minimum 6 Volts of power that a Zendrum requires.
  • Page 7 MIDI IN Connect your Zendrum or another instrument to the MIDI IN jack. Take care when connecting non-Zendrum instruments as phantom power is always delivered through the MIDI IN jack. This typically won’t be a problem for most devices as the two pins used to deliver power are usually ignored. It’s best to consult the user manual for your instrument before plugging it in the first time.
  • Page 8 External CC/Expression Pedals Up to two pedals can be connected with the ¼” jacks on the back of the unit. A broad range of products can be used, including: ● Expression pedals ● Sustain pedals ● Footswitches ● Hi-hat pedals The Shifter Pro supports both TS and TRS connections, though some RTS devices have been known to work also.
  • Page 9: Operation

    Operation Once programmed, you interact with the three footswitches to generate CC messages or to enable/disable your shift rules. The footswitches on the top will illuminate to indicate that they are active. The power LED functions as the MIDI activity light and will flicker whenever MIDI messages are detected.
  • Page 10 Programming the Shifter Pro Programming the Shifter Pro requires that either Google Chrome or the Opera web browser be installed. Connect your Shifter Pro to your computer using a USB cable and navigate to the ZDS Shifter Pro Web Application. The application is split into a number of sections.
  • Page 11 on top of the unit, but any MIDI controller can be used to control them, based on the channel and CC number. Shift Rules A shift rule works on a single MIDI voice message type and value. They have an input and an output definition. The Shifter Pro compares each MIDI message it receives against the list of active shift rules.
  • Page 12 Rules can be used to alter Note On messages like this, or they can be used to completely alter the message type. Consider the following: This rule will turn any CC #64 messages it sees into cymbal hits (the value of the CC message becomes the velocity value for the hit).
  • Page 13 Here we’re having the Shifter Pro automatically play a kick drum sample whenever a crash cymbal is hit. This effectively enables layer stacking for any sound source! When the Rule Type changes to ‘Stack’, an additional ‘velocity/value’ control appears. By default, the generated message will use the same velocity as the original input message, but you also have the option of setting it to 0 (off), 64 (mid) or 127 (on).
  • Page 14 Creating Rules Within each group tab is a button to add new rules: Click this button to display the rule editor. The rule editor is split into Input and Output sections. For each rule, the Shifter Pro listens for messages that match the defined Input and when it finds any, it changes them to match the Output definition.
  • Page 15 You could for instance set up the momentary switch on your Zendrum to control one or more of the groups. So long as the groups see a MIDI message appear for the CC message and channel it is listening for, it will activate, regardless of what device generated it.
  • Page 16 the footswitch and also how it toggles between enabled and disabled states. There are two different types of buttons you can set up, Simple or Ranged. Simple Button There are four settings for each footswitch you can set. The first two settings are for the CC message and channel. By default, the Shifter Pro associates the six shift groups with CC values 110 to 115 (with CC numbers labeled as ‘Shift 1’...
  • Page 17 to change states once in a while or once per song, then the latching behavior would be better suited. The final setting for the footswitches is “polarity”. This controls whether the CC starts off as enabled or disabled when the Shifter Pro is turned on. The default is ‘initially off’, meaning the CC will turn on when you depress the switch.
  • Page 18 CC/ EXP Jacks There are two general categories of pedals that you can use with the Shifter Pro, either a variable pedal or a toggle button. Toggle Button When the pedal type is set to ‘Toggle Button’, all the same controls that are available to the built-in footswitches apply.
  • Page 19 In addition to the standard settings (CC #, channel, polarity) you can also set the min and max values (they default to 0 and 127) and also set the response curve, much like you can do for your Zendrum triggers. These settings are based on personal preference but as an idea, suppose you were using a pedal to tune a snare drum.
  • Page 20 Trigger Jacks The two TRS jacks on the rear labeled ‘Trig’ can each accept one of the following: 1. A dual-zone trigger pad. 2. A single-zone trigger pad. 3. Two separate triggers, each connected to ground (the sleeve) and one to the ring, and one to the tip, as shown here: The main difference between this and a dual-zone pad is that a dual-zone pad will only sound one of the instruments at a time (rim shots are not supported at this time).
  • Page 21 3. Curve. This controls the response curve. The default is linear but you can experiment with other values to get the right “feel”. The curves are quite similar to the ones built into your Zendrum. 4. Scan Time. Scan time refers to how long (in milliseconds) to wait while searching for the peak voltage.
  • Page 22 A hit is detected when the trigger voltage rises above the noise floor and then the scan time begins. A peak voltage is then recorded within the scan duration. Once the scan time expires, the unit enters the mask time and any values, whether they exceed the noise floor or not, are ignored in order to eliminate “double triggering”...
  • Page 23 Trigger Presets Preset values for popular triggers are available and are accessed from the ‘Advanced’ tab. The buttons along the bottom labeled “Apply a Preset” and “Save As Preset” are used to apply and save presets. Applying a Preset From the ‘Advanced’ tab, click the “Apply a Preset…” button to bring up the preset selection dialog.
  • Page 24 If your exact trigger is listed then choose that, otherwise choose one that has similar characteristics to your trigger. Choosing one that has a similar size or form factor should get you into the ballpark. Note that any trigger, even two of the same type, may have slight variations in their performance.
  • Page 25 Creating a New Preset Once you have experimented with and found the best settings for your trigger device, you can save them off as a custom preset. This is done by clicking the “Save As Preset…” button on the ‘Advanced’ tab. There you can choose a name for the preset and optionally specify the manufacturer and trigger type.
  • Page 26 Virtual Hats If you use a sound source such as a Zendrum Stompblock, which does not have native hi-hat pedal support, then you can have the Shifter Pro mimic this functionality for you. To turn on virtual hat support for an attached pedal, first go to the section labeled ‘Virtual Hats’...
  • Page 27 Setting up Mappings The first thing you’ll probably want to do before creating any shift rules is to set the mappings so that they match the hardware or software sound source that you are using. Doing this will ensure that all the note numbers and CC numbers will have relevant display names.
  • Page 28 Pro for MIDI channel 10 (drums). You can select which module/mapping to use for each channel you care about. To import your own mappings, click the button in the lower-left labeled ‘Manage My Custom Mappings’. This will display the list of mappings you’ve imported (if any) as well as controls to import your own files.
  • Page 29: Backup And Restore

    Backup and restore To access the backup and restore features, click on the menu icon the upper-righthand corner. Choose ‘Backup All Settings’ to download the internal state of your ZDS Shifter Pro. The ‘Restore All Settings’ feature can later be used to reload those saved settings.
  • Page 30: Factory Reset

    Choose the options you’d like to print and then click the ‘Print Preview’ button to produce a settings report. Factory Reset Should you ever need to, you can click on the menu icon in the upper-righthand corner of the application to access the ‘Factory Reset’ feature.
  • Page 31 The application will ask you to confirm this action before performing the reset operation. © Nebiru Software, 2021 REV C...
