That’s a lovely track (Zone 3) - not sure what I was expecting, but I really dig the rate of movement (the slow progression), the large dynamic (amplitude) range, and the variety of contrasting yet complimentary textures. The tone, or atmosphere of it, is well-immersive and affecting. Edit: admittedly, I listened to it on my phone (no headphones), but I was compelled to stick with it for the duration. There are sounds occurring during the latter third of it that I couldn’t discern whether or not it was coming from outside, or from music playing quietly in the other room… again, well-immersive, nicely mixed, etc.
Regarding Mangrove vs. tELHARMONIC, I don’t know much about either module, but it seems that the DPO could (?) achieve some of the more obvious qualities of Mangrove, like the lower-register, filtered, near-formant-like growl of “Zone 3”–it’s similar to what I’ve heard of the Mangrove in some videos. It seems like the DPO should be able to cover a broad variety of terrain, compared to Mangrove.
With tELHARMONIC, it seems you could achieve more glassy, bold/clean sorts of sustained voices, with really nice animation effects (the tonic control in particular) w/Centroid etc. - and the polyphony, however useful that could be, interval-wise. There are a few demos of the forthcoming XAOC Odessa module, which remind me of the tELHARMONIC, though it sounds terrifically capable of those brilliant, glassy / laser-like / cutting chords (of varying harmonicity), and more fragmented / percussive / mangled chop. It’s also quite large, at more than 20hp (not certain)
Not sure if you’ve made any decisions, but have you considered Mannequins Just Friends? It’s pretty fantastic, sonically, as well as for a modulation source.
