I like to re-use what I have as much as possible too, so definitely good to use hermod for this … prob is, I use it so much already for midi 2 cv.
self modulation , yeah Im not entirely surprised… hermod is using an mcu to process the signal so thats always going to create a bit of ‘latency’ ( dac → adc ) , whereas I believe ochd is analog, so ‘instant’…
however, with hermod, you don’t have to use triangles , you can use other shapes, and also even chain lfo’s to get other shapes, so really you don’t need to do that self-modulation ‘trick’ you’d use for ochd. also importantly, you can do something different for every track, rather than ochd, where it affects every output.
thats the thing, whenever you get inspired from another module, its often not the ‘same’ but you can enjoy those differences
