Sounds good, has great mod wheel,
Good sequencer, preset memory,
The Panel button that resets sound to what is dialled in with knobs.
Bought as supplement to ASM Hydrasynth, chosen over BassStation II due to semi-weighted keys / playability and also Moog brand.
Since it is a mono synth sometimes I end up abruptly ending a note by lightly touching other key - which can be irritating. Does not happen when playing legato or staccato.
For patch design or sound design explorations I strongly prefer Hydrasynth. For Bass sounds, and acid-like sequneces - Moog shines. Also for hands-on explorations using the knobs - no menu diving is brilliant.
Would not recommend mono-synth like Messenger as first hardware synth - you wanna play lush chord once in a while.
