If you have one synth with 30 reverbs on it, hyper threading won't help as they're all in series and not in parallel.Īs I'm sure you're aware, performance and bug fixing is ongoing work at any company and we'll of course continue improving Reason here at PropellerHQ. Additionally, due to how load is distributed on cores, you will see the biggest performance gain on "normal" projects with multiple tracks, multiple devices and so on. Regarding hyper threading, there are some important things to keep in mind! Depending on your CPU (number of physical cores, virtual cores etc) this will of course do less or more for your performance. There is a new setting for this in the Preferences which is on by default. Dragging MIDI into the Reason sequencer will now place the MIDI on a track and position of your choice. Improved MIDI drag and drop from VST plug-ins.Bumping this to let you know that we just released Reason 9.5.1! For Reason 9.5 users: just launch Reason 9.5 and it'll auto-update. Did you try to increase the threads assigned to all cores, as mentioned in the thread I linked to? Not sure if it will help your plight or not. I was just setting the record straight about Hyperthreading in Reason. Logical cores are almost untouched and those rare activities could be related to other things as I have opened some other tasks in the background (Chrome, Activity monitor app itself).To be clear, I agree that Reason needs to handle multiple cores (and virtual cores) better, and certainly VST performance in this first release needs to be improved upon. As you can notice 1st physical core is loaded the most - to me it is responsible for graphics. From what I see on system monitor, even GUI is processed by 1st physical core. When I use less audio tracks, working with default sample rates and do not use stretch, all my 12 logical cores are out of business. When processing audio is out of HT then 98% of all processing inside Reason is without HT. I thought that Reason is an audio application.

Examples of Hyperthreading in Reason can be found in disc i/o, high quality stretch and resample, and graphics.Īlso, if you feel like toying around with core threads, try this to force Reason to use more cores (both logical and physical): Reason utilizes Hyperthreading for almost everything - except rendering audio.
