I finally had a chance to dig into the new setup this week and my head is still spinning with the possibilities. I agree with Christoph that there is something almost uncanny about Opus 4.6 (I'd add Sonnet 4.6 which I use for most tasks) when it comes to writing Hisescript and editing the source code. Next best models which I find produce useful enough results are GPT-5.4, and Gemini's new multimodal embedding model has piqued my interest as well.
It's still early days of trying out different workflows but what does everyone's setup look like currently? Are you still using the HISE script editor or do you find working out of a separate IDE more convenient at this point? I've been using Visual Studio for the most part launching Claude Code or Codex in Terminal. Admittedly, I still find HISE script editor too useful to completely separate with it...
On another, note how are you all getting along with specific HISE projects at this stage? One thing I am noticing is how much more aggressive Claude code can be on token usage if you don't prompt and direct it right. Previously I would consolidate all necessary information (Scripts, xmls, Dsp Files, scope of work, bug checklist, etc.) along with specific examples, API documentation, or source code from HISE, and create a new project with an LLM. This seems to have the added benefit of keeping the model more focused, faster, use less resources, and most importantly, retain memory. The main drawbacks are lack of project/HISE context and lack of writing to project.
So the MCP server approach does allow for read/write to the project and clearly performs significantly better, but requires careful prompting and project context to avoid significant token usage. Figuring out the right balance between comprehensive context and efficiency is the real challenge for me moving forward. I imagine this just boils down to reformatting my setup to include the right sort of skill, tools and spawning subagents in the right context.
I'll have to try out opencode as Chrsitoph suggests and using this to make edits to the HISE source code are next on my bucket list as well!
