Frequently Asked Questions - Miditerminal 4140 ESI
How do I connect the Miditerminal 4140 to my computer?
The Miditerminal 4140 uses standard 5-pin MIDI connectors. To connect to a computer, you need a MIDI interface or an audio interface with MIDI I/O. Connect the MIDI Out from the keyboard to the MIDI In on the interface, and optionally the MIDI In from the keyboard to the MIDI Out on the interface for two-way communication.
Does the Miditerminal 4140 require a driver to work?
Since it is a class-compliant MIDI device over a traditional MIDI interface, no specific driver is needed for the keyboard itself. The driver for the MIDI interface is required and usually comes with your operating system or the interface manufacturer.
Can I use this keyboard with a DAW like Cubase or Ableton Live?
Yes, it works with any software that supports MIDI. You may need to configure the MIDI ports in your DAW and assign the correct inputs for recording MIDI notes and controller data.
How do I change the MIDI channel on the Miditerminal 4140?
Use the channel up/down buttons on the front panel. The current MIDI channel is typically shown on an LED display or indicated by button status. Refer to the manual for the exact procedure.
Does the keyboard have aftertouch?
Yes, the Miditerminal 4140 features channel aftertouch, which sends pressure messages when keys are pressed harder after hitting the bottom. This allows for expressive playing when used with compatible sound modules or software.
How do I connect a sustain pedal?
Plug a standard sustain pedal (footswitch) into the pedal input jack on the rear panel. The polarity is usually automatic, but some pedals may have a polarity switch to match your keyboard.
Can I power the Miditerminal 4140 via USB?
No, this model does not have USB connectivity. It requires a 9V DC power adapter. Some MIDI interfaces can provide phantom power, but it is not recommended unless explicitly supported.
What is the maximum polyphony?
The keyboard itself does not generate sound; it is a MIDI controller. The polyphony depends on the connected sound module or software synthesizer. This keyboard sends note data without limit from its own hardware.
How do I perform a factory reset?
To restore factory default settings, power off the device, then hold down certain button combinations while powering on. Refer to the manual for the exact reset procedure. If you do not have it, try holding the MIDI and Channel buttons during power-up.
Is it possible to use the keyboard with an iPad or tablet?
Yes, if you have a MIDI adapter such as the Apple Camera Connection Kit with a USB-MIDI interface. The keyboard itself is not USB, so you need a class-compliant MIDI interface that connects to the tablet.
