So for instance ampeg_attack=1.3 ampeg_attack_onCC41=0.5 means as you move cc41 from 0…127 the attack moves from 1.3 to 1.8

(Shortcircuit doesn’t support these opcodes today but sforzando and sfizz and others do)

The sfz format team has been doing a good job keeping the documentation improving at sfzformat.com and is very open to questions and suggestions on their GitHub and discord. Here’s the doc for oncc https://sfzformat.com/modulations/midi_ccs/

I have a cunning plan to import all the oncc opcodes into short circuit mod matrix rows too. But I want to do it in a way which refactors and shares the code among formats a smidge more. I started some of that with the fixes in the beta this week

Nice!

I started reading about AI last night, and then tried my hand at making an AI assisted template with the things I want. I’ll have to research and test for accuracy, but I think my prompts and corrections and AI’s idiot savant-like intelligence made a pretty good team. It’s formatted for a full page, so it won’t look great copied to a forum post, but this is what we came up with after an hour:

Anyone can use this if they want to.

It looks much nicer in a full page text editor. I see some mistakes in it, and I’m sure that there are mistakes I don’t even know about. But over all, I was impressed at what AI was able to do.

yup. i was chatting with some folks about how LLM will be well suited to generate and manipulate SFZ files. Predictable. Textual. Examples. Documented. My guess is claude will be a better UI to SFZ than anything you would drag around with a mouse.

Where can I find the "official" forum for Shortcircuit XT? Links appreciated...

The "official" thread about Shortcircuit in KVR is not yet "setup", we're just using this last one to comment, there are some other threads open here in KVR:

Much Thanks, I'll hop in that discord.

Shortcircuit is still a great samplysizer/synthler/something in between.
TBH, the current SCXT beta is pretty much 95% SC1 + a ton of other extras by now, it's practically replaced the need for the old one for me.

Err...sorry in advance if this is not the right place to ask for this.

Can someone explain to me the philosophy behind the hierarchy of parts -> groups -> zones?

I thought it is equivalent to Kontakt's instruments -> groups -> zones, but I cannot route groups to different outputs, which I find to be very odd...so is this the case or am i missing something?

Thank you

EvilDragon · Post by **EvilDragon** » Mon May 04, 2026 12:47 pm

The hierarchy is exactly like what you say, actually. You can route groups to different outputs. In the left sidepane, select [ GROUPS ]. Then in ROUTING section, you have the output menu below Volume/Pan.

Oof...how could I not see this?

All I saw was the little speaker icon in the bottom right corner of the left sidepane, which led to the message "Group Setting Pane Output is not yet implemented etc..", when clicking on it...

Well thank you, Sir! This helped a lot

EvilDragon · Post by **EvilDragon** » Mon May 04, 2026 1:26 pm

Right, the bidirectional link between the group settings and the Routing section is not implemented yet.

Be advised, when you route zones/groups/parts in SCXT you're routing them to a channel in the internal mixer, not the outputs directly. You'll want to head to the mixer page, click the output near the bottom of any channel (where it says "main") and find the "each channel to separate outputs" option. After that you can if you want forget about the mixer and think about it as routing the groups/zones to separater outputs. Or you could use the mixer to add effects to each output independently.

EvilDragon · Post by **EvilDragon** » Mon May 04, 2026 2:00 pm

...the above is also the same decoupling between internal mixer and host that you can also find in Kontakt, Falcon, HALion, as well.

just the freaking FX section alone is soooo good...damn

Perfect! Thank you so much, that's exactely what I wanted!
