I’d like to assign the arp rate to a S&H LFO and then assign the depth to the mod wheel or Quick Control. I’ve looked thoroughly through the mod destinations and there’s nothing there that is immediately obvious or reroutable. ---

If it’s not possible to assign the rate by LFO is it possible to set the FlexPhraser variations as mod destinations, either by creative routing or scripting? ---

I assume you’ve seen the HALion 6 available parameters in the Modulation Matrix? i.e. modulation sources, modifiers and targets: [Modulation Matrix Parameters](https://steinberg.help/halion/v6/en/halion/topics/editing_zones/zones_modulation_matrix_parameters_r.html?hl=modulation%2Cmatrix) I’m not seeing anything around the FlexPhraser in there. * * * Have you already discovered the HALion scripting reference guide as part of the Steinberg website for developers? [https://developer.steinberg.help/](https://developer.steinberg.help/) I think you’re in deep enough in your quest, that if not now, you’ll need that resource soon! 🤓 It has a couple of sections dedicated to the FlexPhraser: [FlexPhraser - HALion Macro Page - Steinberg Developer Help](https://developer.steinberg.help/display/HMP/FlexPhraser) and [FlexPhraserStepSeq - HALion Macro Page - Steinberg Developer Help](https://developer.steinberg.help/display/HMP/FlexPhraserStepSeq) ---

Yeah I don’t see anything in the mod matrix so I’m hoping there’s a creative way to (re)route things to generate it. I did investigate the CC modifier but no luck. Thanks for the scripting reference guides, I’ll have a read through them. ---

I’ve had a read through and even if I were able to work it out I’m not sure how I’d apply that in the mod matrix 🤷‍♂️ Also, it’s really unfortunate we’re not able to edit the subject line here because I have thought of another way to tackle this so I can either mention is below or start a new thread. I’m reluctant to do the latter but then again I want people to see it 🤔
