Used to have a Phonogene and ended up selling it to fund an ER-301. Morphagene is pretty much what I wanted the Phonogene to be, with longer recording time. Since Morphagene came out, I’ve toyed with the idea of getting one, but have quite a bit of sampling/granulation in my rig already with ER-301 and Clouds.
Phonogene at this point excels at creating grainy textures and deterioration…you can slow down the recording speed and get longer recordings than the (higher quality) 2 seconds. It sounds great if you filter it. Some good examples of this can be found in Taylor Deupree’s studio diaries on soundcloud. (I recommend everybody check those out regardless!)
Morphagene would excel at longer recording, better quality, and the overlapping slices/morph is a unique feature that you won’t find on the Phonogene.
Both of them have end-of-cycle/splice outputs, which is a simple feature yet holds a lot of possibility - I don’t see that mentioned a lot. You can have the module trigger other events in your system. Also, both of them have sound on sound modes that are similar - Morphagene: Time Lag Accumulation and Phonogene: Broken Echo.
