Lots of tech issues getting this one done. For the first time ever Logic would not properly export -- I had to do it in pieces and assemble them. Also had lots of weird things happen, so OB-Xf may need some work. Great sounding synth though!
40 instances in Logic Pro X. Logic EQ, Compressors, Reverb, Delays, Nova Free, Khz Compactor. Enjoy

Welp, I rallied as best I could. Had to start an entirely new track, so I said "screw it" and made a single-instance entry. I quite like it, especially for being thrown together in a few hours.
DAW: Reaper
1 x OB-XF
1 x NastyVCSmkII by Variety of Sound
1 x Epic Clouds by Variety of Sound
Primarily used velocity tied to the filter and amp envelopes to create dynamics. A bit of volume and decay modulation but nothing fancy. Hope you enjoy!

My entry for this month's contest
Tried to keep the sound pretty raw on this one.
168 instances of Ob-Xf
Bitwig 6.0.6 used
https://soundcloud.com/jruegg/beluga
Bitwig devices:
Modulators:
* Macro & 4-Macro (mostly on the bass sounds, to automate many parameters at once)
* Segments (used on ducking and maybe to control the volume of some drum layers)
* Curves (used as a mod remapper by having it at 0hz and modulating the phase, this in combo with the macros can make very crazy sounds)
Containers:
* Drum Machine (making percussion sets)
* Instrument Selector (for polyphonic 32 unison instruments, using an instance per key)
* Instrument Layer (For simple layered sounds)
* FX Layer
* XY Instrument (For the main morphing bass, which was a monster 13 instance layer + 8 macros)
FX devices:
* Tool (Volume & Width settings)
* Eq+ (static usage, no modulation on this)
* Over
* Delay+ (mild usage)
* Peak Limiter (on the master)
Others:
* Oscilloscope (to see the wave)
* Mid-Side Split (for Mid-Side Eqing)
* Note Receiver (for ducking trigger routing)
* Spectrum (to watch the things)
External VST effects:
* OTT (I should try to stop using this thing)
=======================
Listening back to my entry for OSC61 I can see how much I have improved, some things feel different after 12+ years, but others seem to be the same.
This feels like coming full circle, and it's like I've been chasing a certain sound all this time, a sound that has been elusive but I'm getting closer, maybe it's only reachable with samples and outside of the boundaries of a single synth ...
