It's the old pots that make the best soups: more than a decade after their introduction, the M-Audio MIDISport interfaces are still the standard against which everything is measured. They are sturdy, not very picky in terms of configuration (Windows XP is still supported!) and easy to use thanks to the LEDs on the front. Definitely a classic.
In a world where the modern musician often uses hybrid gear, be it a synth a computer or a tablet, iConnectivity strives to offer the best possible solutions. Like the amazing iConnectMIDI2+ MIDI interface which can actually transmit audio without being an audio interface. And it allows you to use your iPhone or iPad as plug-in with your DAW, which certainly makes it one of the most innovative products we've seen in many years in a market where innovation is a rarity.
It's simple, elegant and works: it's a MOTU. There's not much to say about this small beauty with two MIDI inputs/outputs and MIDI Thru other than it's a serious alternative to the MIDISport.
They are small, squared and sport some very handy LEDs. They come in 2x2 or 4x4 format and their biggest advantage over the rest is their price: around $40 for the 2x2 and $50 for the 4x4. You'd have a hard time finding anything cheaper, especially since they don't do any less than their rivals…
