    Hi! What has happened to the automatic 2 second spacing for tracks in the updated Project Page?

  • Sorry to hear that Stuart—unfortunately that’s really hard for me to troubleshoot. My first recommendation would be to try a different browser. If that doesn’t help, submit a support ticket at and our tech team will help you out. Cheers!

    Expectacular actualización por parte de PreSonus… se nota que han estado trabajando a fondo en esta nueva versión, muy contento con las nuevas características que lo hacen mas profesional aún, y con la fluidez y la velocidad para guardar proyectos, hay algún fallo con el midi, pero como en toda actualización grande, siempre salen pequeños fallos que se corrigen pronto… Gracias por este “nuevo” Daw. Thank You PreSonus.

  • Wayne Morgan

    hi william im wayne im having the same problems as you with my midi the way i got round it is instead of choosing a new instrument slot to record in pick the instrument you want then drag it to an empty line under anythimg else youve recorded and it appears ready to use i hope that helps

  • Bailey Redinsomniacs

    Whenever I try to download it, it keeps failing

  • William Swarner

    same very irritating i though my midi controller was broken at 1st as i started my day on ver 3.4 rolled to 3.5 and now im finding issue after issue, and this is the 1st time im going to say this with an update I hate what this did to my daw its less stable cpu wise now than 3.4 and my vst’s just act weird now also midi data doesnt illicit the desired results anymore as it just does whatever it pleases and ignores the user inputs for instruments,I am not sure if its a midi data issue or and issue with the vst compatibility that i paid an extra hundred bucks to add (comes free in almost all daws even non major ones)but felt back at the time of purchase it was worth it as this daw was superior (even without your new features) in all the ways i needed it to be, now not so much as for me my 3 favotite features were just hit, stabilty (worse than ver 3.4) VST’s not holding settings (preset created or loaded from presets) when midi data is put into that track, and that ability to manipulate midi data and create something new (this is vital to a daw guys needs fixed)PLEASE 🙂

  • William Swarner

    I am having a similar issue except when using midi either instrument (vst) setting change always back to preset #1 or the track even goes silent giving no playback, when saving after making instrument changes the daw still reverts the instruments back to initial settings when using midi, and a lot of my projects right now REALLY require midi for part of the piece

    I was working with a video prior to the update. Now after the 3.5 update there is no video, just a black screen. Also the video does not move with the rest of the track.

    I have tried deleting the video and loading again but it doesn’t seem to work. Have a deadline in 2 days 🙁

  • Brandon Jones

    Updated to 3.5 and now I can’t save any new projects… help please

  • Darryl Beaton

    My FP8 isn’t working in SO3.5 but is working in Logic. Any ideas why?

  • Primal Cashew

    after the update, studio one is completely muted. Help!

  • Chris Casey

    I had to edit my External Devices and update the Receive From and Send To settings. Since then, no issues for me.

  • Chris Casey

    This update has really revived my DAW rig. My rig is old and I’ve been having to record with a 1024 block size on my 44VXL to avoid drop-outs. The issues I’ve had with drop-outs and my system bogging down are gone, regardless of whether I use low latency monitoring or not. Thanks Presonus! I can begin enjoying creating music again!

  • Ok I figured out my midi problems…I had to re initialize the midi instruments and FX and manual re connect everything…now it works as expected…a bit of a pain in the ass, but VERY happy with this Update…

  • Lorkaxx BeaTs

    i have problem with my graphic card R7 M260 – amd processor

  • Al Ramirez

    also my midi device didn’t connect until the fourth try…weird
    hope it connects from now on.
    PRESONUS please stop adding features an concentrate on the engines
    every time you add something you break something…enough is enough i spend
    more time dealing with the program than making music

  • Roque Luis Figliuolo


  • Well I spoke to soon,know my midi device won’t connect….:-(
    Re Boot, re connect…nothing..
    Can we roll back to previous version?

  • Nice update 🙂
    Thanks !!!
