M4 : Good interface, low latency

Very well made interface, good and useful controls from the front panel and the display level indicator is very accurate and responsive. A peak memory indicator would be nice in a future firmware upgrade. The monitor mix potentiometer lacks a very useful center detent. Unfortunately lots of products have gained a 10/15% price increase lately which is now considered normal… but this is a no-frill simple audio interface and there is no rocket science inside to justify completely its price against its real value. I appreciate that it works straight away on MacOS and the driver are very fast (starting from 96kHz SR and more) and they don’t come with bloatware. MOTU seems to me very serious about respecting artists and they offer bloatware in form of plugins loops and demo software, but if you are already covered, just steer away from it and don’t waste time, make music instead!
