The stereo linking cable is a simple cable which is installed between 2 of our DSP driven 500 series modules. It allows a “master” module to send all parameters to a 2nd unit in the rack. This way 2 Mercury7 reverb modules, for example, can be linked together to synchronize their parameters. The “master” end of the stereo linking cable is indicated by a piece of white heat shrink tubing.
Our effects pedals can interface with almost any standard expression pedal with a TRS style 1/4″ cable. The Moog EP-3 or Dunlop DVP3 are both good choices.
Our EXP jack can be configured in the global settings to accept MIDI input and also send MIDI data. In order to adapt to the 5 pin DIN MIDI standard, an external adapter is required. Now available is the Meris MIDI I/O which will work seamlessly with Meris pedals. The Meris MIDI I/O allows you to control up to 4 Meris pedals via MIDI, MIDI controller, wireless with a bluetooth adapter, from your DAW, etc.
***Also compatible with Empress and Chase Bliss* pedals (*requires special cable)
Each of our pedals supports up to 16 internal presets. A Meris Preset Switch can give you simple, instant access to the first 4 presets. To save a preset, press one of the footswitches on the preset switch, modify your sound, then hold ALT to save.
A MIDI I/O will give you access to all 16 internal presets via midi program change messages. To save a preset, send the desired midi pc message via a midi controller or application, modify your sound, then hold ALT to save.
Meris pedals use a standard 9V DC center-negative power supply capable of at least 150mA of output current capability. Standard 9V “boss style” power supplies will work with Meris pedals as long as they can output more than 150mA. Daisy chain power supply configurations are discouraged since they can cause noise and ground loops. Multi output isolated power supplies are recommended as long as the high current outputs are used for Meris pedals.
The input jack on all Meris pedals can be set to accept a TRS stereo input signal. You will need a TRS-Y cable adapter to connect the L and R input cables to the TRS stereo input. You must set your Meris pedal to TRS Stereo input in the global settings mode. The TRS Stereo LED will light on the back of your pedal when in this mode.
Meris pedals ship from the factory in mono input mode. Plug your instrument or previous pedal in the chain into the input jack with a standard unbalanced mono 1/4” cable. Use the LEFT output jack for mono operation. Any stereo effect from the pedal will be converted to mono when the LEFT output jack is connected alone.
We recommend using a MIDI to TRS conversion box, like our MIDI I/O, to send MIDI to Meris pedals. MIDI Standard requires the active opto-isolator electronics built into these boxes for a reliable, guaranteed connection. There are MIDI to TRS cables available on the market, but we cannot guarantee their reliability or compatibility. Converting MIDI to TRS without the required active electronics can cause grounding issues, latency, reliability issues or non-functionality.
After entering global settings mode and setting the desired settings, simply power down (unplug the power cable) to save those settings. When you power up the pedal again in normal mode (don’t hold any switches), the new global settings will be applied. Your global settings will remain until they are changed again or a “factory reset” is performed.
Meris pedals can use incoming CV (control voltage) from 0-3.3V to sync tempo or modulate parameters. To sync to clock: set your Meris pedal’s EXP jack to Tap in the global settings and send an inverted pulse wave clock signal. Set the EXP jack to expression to use incoming CV (0-3.3V) to modulate parameters like an expression pedal would. The 0V and 3.3V extremes will act the same as the “heel” and “toe” of an expression pedal. All parameters can be modulated simultaneously.
MIDI control of our pedals will allow you to control 16 presets and use an expression pedal at the same time, as long as your MIDI controller has an expression jack. Connect your expression pedal to your MIDI controller and assign CC#4 with a range of 0-127. The expression pedal will work just as it would without MIDI; a separate heel and toe setting and the expression pedal morphing between all parameters simultaneously. Heel and Toe expression settings are saved within each preset. After setting your heel and toe settings, hold ALT to save. When you recall the preset with a PC message, the expression pedal settings will be saved.
