Scene Sounds
Starting now, I won't be using the sfx found in Studio on my scenes. They are a bit limiting and timing can be hard to do there.
Instead, I'll be using the sounds I made for the videos. For this, you'll need Birds of Hermes plugin.
Birds of Hermes

Get at least the v5 above.
This plugin allows importing audio files into the scenes. There are also other audio effects you can use. It has a UI that allows mixing audio.
Bird of Hermes - Link
You need to join Koikatsu discord to access the link. Please read the descriptions for what it can do and get a latest version.
There will be 2 tracks per scene. First track is SFX + Moan, second track is SFX Only which is muted by default. You can mute/unmute track through 'M' button.
This will increase the scene size, so you can delete the other one if you want.

I recommend manually updating specific plugins listed below.
Create a copy of your BepInEx folder first for backup so you won't be afraid messing up things. Pretty much it's just copy and replace.
Bird of Hermes requires latest Timeline (included in HSPlugins) and KKAPI.
Try installing Timeline through HSPlugins first and see if it's enough.
- HSPplugins : Download the KK or KKS version depending on what you're using. Open it then the Timeline, then drag the BepInEx folder on your Koikatsu directory then just choose replace. (You can also install the other plugins in HSPlugins if you want)
If updating Timeline is not enough, you need to install KKAPI and BepisPlugins which is its requirements. Almost the same instruction as above, just copy and replace.
For Madevil pack users
As you can see from the comments. You can use VN Sounds to insert the audio files in the scene. I posted the link for the audio files at the same post where the scene archive link is located.







Would it be possible for you to include, alongside each such release, the actual audio file(s) you used for that scene?
Here's why I'm asking:
I'm currently using the Madevil pack, and I can't install the Birds of Hermes plugin at all.
I've tried switching to the HF pack instead, but that breaks a large number of my character cards—they rely on plugins (like WTF) that aren't available in the HF environment, and fixing all of them would be an absolute nightmare.
If you could just provide the audio file you used for each scene using Birds of Hermes plugin, I could load it into VN Sound manually. It wouldn't be a perfect replacement, but the result would still be decent enough for my use.
I totally understand if this is too much extra work, but I'd really appreciate it if you could consider doing this going forward.
Thanks in advance for your time! :)
Thanks a lot! :)
Any specific madevil plugin that causes Hermes to not work?
I can't fix compatibility issues with Hermes when it's not reported
@metiks I've really have no idea why Hermes is incomptible with Madevil plugins, cause i thought those are mostly for characters. Maybe output_log.txt can tell the reason. Try to install Hermes, open Studio, then send me your output_log.txt (inside koikatsu folder)
@sixpluswan I am... the creator of Hermes... I was asking so I can fix that issue.
ohmygod. thanks for coming here. I'll dm the op if he could provide more details about the problem.
I'm looking for the latest version of 'Birds of Hermes,' but it seems like that link no longer works. Where should I look? Sorry, I'm not very good at English.
