Frequently Asked Questions - MIDI 2hp

How do I change the mode on the 2hp MIDI module?

Press and hold the Mode Button until all LEDs illuminate. Then press the button repeatedly to cycle through modes (indicated by which LED is lit: CV1 = Monophonic, CV2 = Duophonic, Gate1 = Dual Monophonic, Gate2 = Quad Trigger/Gate). Press and hold again to confirm the selection.

What do the LED indicators mean?

Each output has a corresponding LED (CV1, CV2, Gate1, Gate2) that lights when a signal is present. The MIDI Status LED indicates active MIDI communication.

How do I set up the module in my Eurorack case?

Connect the power cable with the red stripe facing -12V (usually bottom of the bus board). Plug the USB Mini into your computer or MIDI device. The module is class compliant and requires no driver installation.

What is the difference between Monophonic and Duophonic modes?

In Monophonic mode, the module plays one note at a time, with CV1 for pitch and CV2 for velocity or other data. In Duophonic mode, it handles two simultaneous notes, with the newest note appearing on the least recently updated CV/Gate pair.

How do I use MIDI Clock with this module?

In Monophonic mode, Gate2 outputs MIDI Clock at a PPQN rate determined by the MIDI channel (e.g., channel 1 = 1 PPQN, channel 4 = 24 PPQN). Other modes may not output clock automatically.

Can I control the module with a DAW?

Yes, the module is a class compliant MIDI device, so it works with any DAW on Mac, PC, or Linux via USB. Just assign MIDI tracks to the module and send notes, CC, or clock.

What are the specifications for CV outputs?

Both CV outputs have a range of 0V to 5V with 12-bit resolution. They are configurable per mode and MIDI channel (e.g., pitch, velocity, CC).

What MIDI channels are used for different functions?

In Monophonic mode, channels 1-12 offer different CV2 and Gate2 behaviors (e.g., velocity, CC1, gate, clock). Channels 13-16 mirror channel 1. In Dual Monophonic mode, channel 1 (or 3-16) controls CV1/Gate1, and channel 2 controls CV2/Gate2.

How do I get Quad Trigger mode?

Select Quad Trigger/Gate mode by pressing the Mode Button until Gate2 LED is lit. In this mode, each output triggers a specific note: CV1 = C1, CV2 = D1, Gate1 = E1, Gate2 = F1. MIDI channels 1 or 3-16 produce 6ms triggers, channel 2 produces gates.

Is the module USB powered?

No, the module requires Eurorack power (+12V and -12V). The USB connection is only for MIDI data, not power.

USER MANUAL MIDI 2hp

MIDI is a plug and play solution for interfacing with your computer or MIDI hardware. Four modes provide monophonic, duophonic, dual mono, and quad trigger operation.

MIDI clock, CC messages, and note on messages are all easily accessible between the four modes. The status LED provides clear indication of MIDI data being received by the module. Class compliant MIDI device on Mac/PC/Linux. Get connected with MIDI.

• USB mini connector
• 2 CV outputs (12 bit resolution)
• 2 Gate outputs
• MIDI Clock
• Class compliant MIDI device on Mac/PC/Linux
• MIDI monitor status LED

Installation

To install, locate 2 HP of space in your Eurorack case and confirm the positive 12 volts and negative 12 volts sides of the power distribution lines. Plug the connector into the power distribution board of your case, keeping in mind that the red band corresponds to negative 12 volts. In most systems, the negative 12 volt supply line is at the bottom. The power cable should be connected to the MIDI with the red band facing the front of the module.
