Frequently Asked Questions - Percussion Interface 4ms
What type of connections does the Percussion Interface use?
The module uses 3.5 mm jacks for trigger inputs, audio outputs, and CV modulation inputs. Power is supplied via a standard 10-pin Eurorack ribbon cable.
Can I use the module with external drum pads or MIDI controllers?
Yes, you can trigger the channels with any gate or trigger signal (0-5V or higher). A MIDI-to-trigger converter can be used for MIDI drum pads.
How do I power the Percussion Interface?
Connect the included 10-pin ribbon cable to your Eurorack case's power bus, ensuring correct polarity (red stripe for -12V). The module draws 50 mA on +12V and 10 mA on -12V.
What sounds does the module produce?
The Percussion Interface generates synthesized percussion sounds including kick, snare, hi-hat, and tom. Each channel has controls for sensitivity, accent, and tone to shape the sound.
Can I chain multiple Percussion Interface modules?
Yes, you can link channels between modules via the link input/output (not present on all versions). Consult the manual for chaining multiple units.
How do I update the firmware?
The Percussion Interface does not have user-upgradeable firmware. All parameters are adjusted via front panel knobs and CV inputs.
What is the maximum trigger input voltage?
The trigger inputs accept up to 10V. Higher voltages may damage the module. Use a voltage divider if necessary.
Can I mute individual channels?
Yes, pressing and holding the channel's trigger input for 2 seconds mutes that channel. The front panel LED will blink to indicate mute status.
How do I clean the module?
Power off and unplug the module. Wipe the front panel with a soft, dry cloth. Do not use liquids or solvents, as they may damage the electronics.
Is there a manual available for download?
Yes, the user manual can be downloaded from the 4ms website or from pages like notice-facile.com. It contains detailed specifications and connection diagrams.
