MOTU Micro Express USB
In Stock!

Compact USB-Powered MIDI with Sync!

The Micro Express is a mini version of the MIDI Express XT. It has many of the same features as the Express XT - except that it is smaller and even more affordable. The micro Express is a half-rack unit with 4 inputs and 6 outputs.

MOTU Micro Express at a Glance:
  • Easy USB interface for timing accuracy and plug-and-play connections
  • Handles all MIDI functions with ease
  • Multiple synchronization options for use with other gear

Easy USB interface for timing accuracy and plug-and-play connections
The Micro Express takes full advantage of USB, giving you increased MIDI throughput, better timing accuracy, support for "hot-swapping" and plug-and-play expansion. Plus, the Micro Express can be powered by the USB bus of your Mac or PC!Need to connect another sound module or synth? No problem. Just add another Micro Express or any MOTU USB MIDI interface via a standard USB hub.

Handles all MIDI functions with ease
The Micro Express delivers a lot of MIDI control in a small package. With 4-in, 6-out capability, the Micro Express gives you control of up to 96 independent MIDI channels. You can merge any inputs to any outputs, route any inputs to any outputs, mute any MIDI data on any cable and re-channelize data on input and output. This means the Micro Express is great for your studio setup and your live performance rig!

Multiple synchronization options for use with other gear
Just because it's small, don't think the Micro Express is short on functionality. In fact, it offers many synchronization options for locking up your MIDI gear with sequencers, digital recorders and video feeds. With the Micro Express you can:

  • Generate and read SMPTE time code (LTC)
  • Convert LTC to MIDI Time Code (MTC) to sync a Mac, PC or other devices to SMPTE
  • Convert all SMPTE frame rates (24, 25, 29.97 drop, 29.97 non-drop, 30)
  • Stripe SMPTE time code in all frame rates
  • Convert MIDI Time Code to SMPTE time code
  • Operate in SMPTE "Jam Sync" with adjustable freewheeling for dropout-free sync
  • Connect MIDI Machine Control devices and serve as either an MMC master or slave

Extremely Please with the Micro Express

Very easy to install drivers & setup. I bought this to use with Cakewalk Pro Audio ver 9 & Roland VS recorders. (VS-1680 & VS-880ex) I was having problems with a Midi Sport 2x2. Cakewalk kept crashing when using MTC. Once I plugged everything in with the Micro Express it worked extremely well & in sync. I found the unit to be well built, solid & expert workmanship. This is a high quality unit. No regrets. I'm back recording again.

Sweetwater Advice

From old school MIDI studios to Film and Post production facilities, this little 1/2-rack will be a loyal liason between the outside MIDI world and your computer DAW/sequencer.

MOTU is the world leader in MIDI interfaces and really always has been. They provide the best bang-for-the-buck as well as the most features and RELIABILITY. The MicroExpressUSB is no exception. With SMPTE striping and syncing ability, 4 in and 6 out MIDI, footpedal input (for locking a human drummer to MIDI clock!), and USB connectivity, you can't beat the MicroExpressUSB for $250!!! IF you don't need 8 ins and outs, get the MicroExpress!
