Hi, I want to optimize setting parameters by using parameter id instead of name. I found that I can only retrieve PARAMETER\_ID from EventDescription. What I also found is that parameters with same name have same ID. And I have plenty of same parameters for different events, like “Speed” or “2D” for dozens of events. And I simply reuse same constant for different events. I see no API for retrieving parameter globally by name and type, but maybe there is an API for retrieving all events of specific bank so I can search their parameters and cache their ids? ---

Hi, > [@Lekret](#): > > API for retrieving all events of specific bank An option may be [FMOD Studio | Studio API Reference - Studio:: Bank::getEventList](https://fmod.com/docs/2.02/api/studio-api-bank.html#studio_bank_geteventlist) which will return an array of all the events added to the bank. You can retrieve a list of loaded banks with [FMOD Studio | Studio API Reference - Studio::System::getBankList](https://fmod.com/docs/2.02/api/studio-api-system.html#studio_system_getbanklist). > [@Lekret](#): > > I want to optimize setting parameters by using parameter id instead of name. Would it be possible to elaborate on this? ---

> Would it be possible to elaborate on this? eventInstance.setParameterByName calls byteFromStringUTF8 on each call on Unity side. When I changed it to setParameterById it became 2 times faster in build. > An option may be [FMOD Studio | Studio API Reference - Studio:: Bank::getEventList](https://fmod.com/docs/2.02/api/studio-api-bank.html#studio_bank_geteventlist) which will return an array of all the events added to the bank. You can retrieve a list of loaded banks with [FMOD Studio | Studio API Reference - Studio::System::getBankList](https://fmod.com/docs/2.02/api/studio-api-system.html#studio_system_getbanklist). I found that, but I will have much more banks and iterating across all of banks and all of events is thing I want to avoid. I have cached list of bank names obtained by [BankRef] and I want to find a way to use them to get bank. Because from what I found I can Load/Unload bank by name, but RuntimeManager.StudioSystem.getBank can only accept path and guid. EditorRefBank has no guid, and path will probably be invalid in build (am I right?), so I’m stuck with names and I can’t use them for getting the actual Bank struct which will provide me access to all events. ---

I have been dealing with this problem by grabbing the IDs manually from the FMOD Cache and storing them in a scriptable object. It works fine, but it would save time to do it in code. ---

FMOD Studio also has the ability to build a ‘GUIDs.txt’ file (in the File menu) which contains all the guids and strings for banks, buses, events, parameters, and snapshots.
