I have built some on the H9000, but not sure I can migrate them to the H90
I’m curious on how you structured that (the component algorithms / patching you used). I have a POG-like Program (DynaVerb OmniPressor -> PolyPhony) that I’ve considered modifying as a natural harmonic feedbacker. Perhaps using the HotSwitches for FreqOut-like harmonic switching. I’d need to re-configure some kind of trailing sustain into the mix.
The manual with the block diagram for one example is available here – https://godlike.com.au/fileadmin/godlike/patch/h9000/manuals/Dub_Delay_Para_User_Guide.pdf
On the H9000 its possible to completely rewire things at the algorithm level, whereas the H90 seems to be more like rearranging existing algorithms, similar to a H9000 chain (I don’t own a H9 or H90). I’m not sure if it is possible to load a custom algorithm onto the H90 without Eventide’s help. I suspect that they use the same toolkit to build the H90 algorithms, but pretty sure they have a custom tool to prepare algorithms for the H90, as opposed to the H9000.
