UMC32+ USB-MIDI Controller

Replacement: None. We don't carry a direct replacement for this board, but have a look at our development tools category. This page is for reference only.

The UMC32+ is an OEM/DIY product that allows electronic musicians, multimedia artists, experimenters, and users with little or no electronics experience the ability to create custom user interfaces to control any software application that supports the MIDI protocol. The UMC32 provides the essential core (micro controller, power supply, USB functionality) to allow the user to easily implement their choice of control elements (example: switches, pots and or faders). In short, the UMC32 will allow you to build your own USB-MIDI controller.

No programming is necessary. Onboard DIP switches allow simple configuration of MIDI note or controller data.

  • Easy to implement with little or no electronics experience.
  • 32 analog and/or digital inputs provides MIDI note or continuous controller data to your host application.
  • USB bus powered. A single USB cable handles power and data.
  • Upgradeable firmware via Windows XP / Vista bootloader utility.
  • True plug-and-play (USB-MIDI class compliant drivers are provided by the operating system)
  • 64 I/O’s can be achieved by linking two UMC32’s together using the UMC-Linker board (sold separately).
  • Multiple units can co-exist on the USB bus.
  • Compatible with all versions of Mac OS X, Windows 7 / Vista / XP / 2000.
  • A redesigned PCB with dedicated GND and VCC planes for enhanced signal integrity.
  • I/O Configuration is now handled entirely by the configuration utility.
  • Connector for external status LED, on board status LED is now blue.
  • USB connector is now the standard TYPE B and is much more secure.
  • Mounting holes (#4 screw) close to USB connector make for a near bulletproof installation.
  • Linkable with the original UMC32
  • RoHS Compliant (lead Free), manufactured to IPC-A-610 Rev. B, Class II.
  • 1.6" x 2.7"

    Hi. I wish to make a wireless bridge via a pair of XBees, one connected to an UMC32 and the other one connected to a PC. Which pieces do I need to buy for this project? I'll be very glad if you can give me an advice about this.

    do you sell the UMC linker board also?

      They do not. I'm sure they would be open to the possibility of carrying it though.

    Can you attach standard midi connectors to use this as a midi-usb bridge? I'm trying to make a midi console and would like to be able to output midi commands to other midi devices and not just a usb port.

    Is it also compatible with Mac OS X 10.6 (SnowLeopard)? The list above is oddly specific, while the User's Guide says "compatible with all versions of Mac OS X." (And that could be quite a few versions, if you believe the "Copyright 2007 - 20,010" at the bottom of pages 2 and later! :-) )

      The current description and links is for the old version and does not match the plus.
