I’ve set up a “home made” multitrack solution for playing backing tracks using multiple instances of the Streaming Audio File Player, and tied them all to the global playhead. The setup itself (mixing and muting tracks on the fly, keeping the tracks in sync, etc) works nicely, but I’m experiencing …

In case someone else has the same issue and finds this thread; here’s an update on this now that I’ve played around some more. Yes, buffer size definitely seems to have been the culprit here. I actually needed to go up to 512 samples before I stopped hearing glitches completely. So what I ended up…

With 16 Samples I can hear some glitches. But to be honest, 16 samples is riding to hell Why do you need such low buffer size? Try with a higher buffer size.

I think 16 or even 32 samples buffer size are not necessary. A simple calculation: When your Amp is 1 m away then you have natural latency of 3 ms On my system 16 samples buffer have a latency of 0.4 ms Buffer size of 128 has a latency of 2.9 ms. Do you really hear the difference between 0.4 ms…

When you really need that low latency for playing guitar, you can use a 2nd instance of GP and set a higher buffer size. On your main instance you can play the guitar and the 2nd instance is playing the backing tracks. Both instances can easily be synced via enabling OSC. No need for another solu…

On my system for 64 samples I get a latent of 1.5 ms, means 0.5 m distance in real situations between you and the amp. So this would mean that you cannot really play guitar when the amp is 0.5 m away from you.

[image] pianopaul: Do you really hear the difference between 0.4 ms and 2.9 ms ? Probably not, but those aren’t real world numbers. Each plugin adds its own latency too. From experience I know that at 64 samples I will generally start noticing it with my main plugins (Neural DSP and/or Helix…

[image] EskilS: Each plugin adds its own latency too There are many plugins which do not add latency. At least they do not report latency :wink:

[image] pianopaul: There are many plugins which do not add latency. Unless they have a dry through function and only add a wet signal in parallel (like a delay or reverb plugin), I don’t see how that’s possible. It might be low, but any plugin that processes and alters the dry signal coming i…

[image] EskilS: At 64 samples, the latency starts getting annoying for guitars. Of course this is personal taste/feel/experience and I’m not telling you what to do, but I’m a guitar/bass player as well and I’m fine with everything between 128 and 256 samples (at 48Khz). For me lower is nice, …

16 samples, wow. I think that Apollo might not be quite stable at that buffer size. Definitely try with 32 samples as a start. I have Behringer and Audient interfaces, if I needed those levels, I’d go after RME Babyface Pro FS (or something else in the RME world).
