Your only other option is to directly interact with the Core API, which means you lose out on all Studio functionality. > [@spakment](#): > > The event that will hold the programmer instrument will be looped quite often, is there a way to “fix” a sound to a programmer instrument rather than having to respond to the callback every time the loop repeats? There isn’t a way to “fix” the sound to a programmer instrument - essentially, once the programmer instrument untriggers it loses its association with the sound. However, you should be able to create a sound a single time in your own code, and then pass it into the event callback using user data so you can get the programmer instrument to play it. Take a look at this reply for an example on how you might do so: [Adding effects to real-time recorded audio - #2 by Connor\_FMOD](https://qa.fmod.com/t/adding-effects-to-real-time-recorded-audio/21265/2) > [@spakment](#): > > Alternate solution; at runtime with built banks can I add sounds to events in a similar way to scripting in studio (eg, studio.project.create(‘SingleSound’) and then adding it to an event track). I can’t find any mention of this in the runtime APIs so I assume its not an option. No, this isn’t an option. > [@spakment](#): > > Are there any utilities that are prefered for batch compressing audio files outside of banks to vorbis? A few options come to mind, such as ffmpeg, Audacity, and fre:ac, but there may be other options out there that suit your needs better. --- _[View the full topic](https://qa.fmod.com/t/programmer-instruments-sounds-from-urls-usage-alternatives-questions/21388)._
