My Main Case:
I've organised more in line with things being complete voices, moved the SSF Vortices to be a bit more central and kicked out some of the more esoteric modules to my new case, the most recent addition is the AfterLater Compactor which I can feed my main basslines to from my Top Case via the DPW M1 Mixer for some Side chaining. I now note that I could do with a Mutes to mute the audio signal of the kick rather than muting the Kick sequence that controls the compressor so that the signal doesn't go back to a high state.
Top Case:
Broadly speaking this case is near perfect for me, though there is a possibility I'll swap the Font filter to something else and maybe get a dedicated Effects module rather than the Disting.
Percussion Case:
I'm kinda tempted by the Nano OCTA but something else would have to go if I did, I guess I'm not always happy with the sound of the Patching Panda BD-Z and one of the ADDAC T-Networks could move.
New Rack:
This is currently just a higgledipiggledy mess, I'm selling the Befaco EvenVCO and ADSR on ebay, I didn't use the VCO enough and the ADSR takes up too much room and doesn't have an inverted out so will be swapping that to be an ST Modular ADSR in just 4hp for the main case and I want the 4hp Befaco Mixer too which will complete the main case.
In an ideal world I'd probably upgrade the Main Case to be 104hp and get rid of the New Rack as I have a bit of a space issue.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
