Motu M4 Audio Interface

Een solide audio interface met een bijzonder lage ruisvloer. Ik heb deze audio interface vooral gekocht voor de bijna latency vrije werking i.c.m. mijn iPhone.
Voor het omzetten van mijn gitaargeluid naar midi gebruik ik een plugin die de midi noten doorstuurt naar synthesizer plugins. De Motu maakt het mogelijk om het gewone gitaargeluid en het synthesizer geluid zo goed als gelijktijdig te kunnen weergeven. De het zuivere signaal is de tracking van de noten door de gitaar naar midi plugin ook tref zeker. Verder zijn de meters op het display erg handig om de levels te kunnen controleren. Ik heb uiteindelijk de Motu M4 vervangen door de Motu M2 omdat ik met de Motu M2 al over voldoende inputs, outputs en midi aanfluitingen kan beschikken. En het formaat van de Motu M2 is net iets praktischer voor mijn pedalboard.

Motu M4 Audio Interface

Prima aankoop na goed advies bij Bax Goes. Aangegeven procedure volgen en de interface werkt binnen enkele minuten ! Tevens koptelefoon bij gekocht, set klinkt als een klok.
Al met al zeer tevreden.

Motu M4 Audio Interface

Produit repondant parfaitement a mon besoin mini studio avec utilisation de cubase pro 15 et clavier maitres avec enceintes de monitoring. J ai reduis considerablement le temps de latence avec une audio superbe permettant de faire des enregistrements temps reels sans aucun soucis. Je recommande ce produit.

Motu M4 Audio Interface

Works like charm with my Mac Pro. It feels like a huge Pro upgrade from a Focusrite that I was previously using.

Motu M4 Audio Interface

Na de M2 te gebruiken gedurende een aantal jaren, kwam ik inputs te kort. De M4 komt met exact dezelfde specificaties en twee extra inputs. Top kwaliteit die nooit teleursteld!

Motu M4 Audio Interface

Hoefde geen drivers te downloaden, werkte gewoon out of the box!! Geluid is super transparant en ik merkte bij hoge amplificatie ook geen enkele vervorming!

Motu M4 Audio Interface

De motu M4 aangesloten en binnen de 2 minuten werkte die perfect via Linux. Ondertussen getest met ubuntu, mint en zorin en alles werkt perfect. Tot daar het goede nieuws. Ik kocht de motu M4 niet alleen voor z'n zeer goede kwaliteit maar ook omdat zowel MOTU als BAX aangaf dat deze ook moet werken op een PC met WIN 7. Niet dus. Echt geen noot muziek uit te krijgen. De support van BAX stuurde me een link naar een driver site van MOTU maar die geeft aan dat de MOTU M4 enkel WIN 10 is. Ik weet dat WIN 7 al geruime tijd voorbij is maar waarom dan vermelden dat deze compatibel is met WIN 7 ? ik heb nog een standalone PC met oa een oudere vesie van Reason die ik graag wou blijven gebruiken.

Motu M4 Audio Interface

Mooi product makkelijk in gebruik en werkt goed met alle Daw software en wat het makkelijkste is met deze is dat je met het kleine LCD schermpje makkelijk de gains kan afstellen
