dont overuse the internal Air VCA. if you modulate it with envelopes, be sure to be able to attenuate the level of modulation BEFORE reaching the Air cv in.
start with the barrel at noon position, its bipolar, the softer spot is in the middle (iirc, i sold my mangrove months ago).
go light with all modulations, use attenuators or vca’s on them before hitting barrel, air and formant cv in.
it can be an adorable soft very organic vco, no harshness if you dont want it. it can sound like a very jazzy brass source if you caress it soft enough
