• Hi, I’m primarily a musician and only just recently decided to dive into the realm of music production. I have chosen reaper as my DAW of choice and am using the free version of amplitube 5 as my amp sim. Now the problem i have run into is when i playback with DI i get almost no latency from what i play however when i activate my vst for the amp i get about 90-95ms delay which throws me off when playing to a guide track is there any remedy to this as I cant think of where or how this problem might be potentially fixed. (I’m recording my tracks using a SSL 2)

      • @adrian.parzentny is definitely your man for this question

        • Hey @Clive.B thanks for your question, I’m Ady and the “Music Production Guy” on this platform, to help you with this issue.

          The first thing you need to check is the so called “Requested Block Size” also know as buffer size in other programs. You can find it in Reaper here (See screenshots)

          1. REAPER > Settings …

          2. Go to the “Audio” Section and Choose “Device” and you will be able to setup the requested block size.

          When recording without any plugins or just a few, you need to put it low, like 64 or 128

          When mixing and processing your mix, you need to put it up to 512 or 1024

          Please let me also know on what computer do you work and what are the specifications:

          How much RAM do you have?
          How much Disk Space is left on your computer?
          What processor do you use (Intel or Silicon like M1, M2 ..)

          I use a macbook Pro with M1 chip and 16 GB RAM, incl a 1TB SSD Hard Drive and it all works fine

          Why do you need to change the requested Buffer?

          This is the tempo how fast your audio will be processed, imagine it like a glass getting filled with water:

          Once the Glass is full, it will be forwarded to someone to drink and filled up again

          If the Buffer size is low, like 64, you have a “small Glass” perfect for recording! Why? It’s quickly full and the information get’s moved on to the computer processor, so the smaller it is, the faster you record and you won’t hear any delay .. if you use a plugin at the same time it might need some more processing power, that’s why you need to experiment between 64 and 128

          If your glass is “too big” during recording, you have a delay, because the Glass waits until it’s full (1024) so you have a delay. Makes sense?

          Anyway, if you start mixing with lots of plugins, they will use a “lot of information” so a small Glass would be “too small” to handle all the information “on time” , the information would have to wait all the time, until they get passed on and can result in crackles and noises because they are not fully processed.

          That’s why you need to increase it when mixing, because more information will be required to be processed at the same time 🙂

          Hope that helps! All the best,

          Ady
