Using my OC-2 as the classic one-octave down synth vibe always took a couple pedals...it plus a bypass/loop pedal with a level/volume control. I never liked the buffer on the pedal and if you want unity gain out of it with a single octave you have to boost the level out. So it's already a win to have a single pedal do that sound.
The Boss OC-2 is a curious pedal. It doesn't have a true bypass, but a buffered bypass. It doesn't like buffered inputs...so one has to be really careful what's coming into the pedal too. Consequently, it prefers a passive bass signal to an active one. Active basses have completely different impedance...so it's not as simple of "just turning down" the active bass. Which is why some bassists get a great result and others get very different responses from their OC-2. There have been many attempts to "modernify" the classic Boss OC-2. Ie sort out the bypass buffer...sort out the input buffer stage...smaller enclosure...opting for a dedicated Oct 1 down (no blend) control. These have been hit or miss due to the inherent complexity of the base circuit or the various basses being put through them. There's not really a one box solution to the OC-2 dilemma. Most of them can get close to "their own bass" through a Boss OC2...but it's never going to exactly match it for every possible scenario. Personally, I've got by with an MXR BOD for a few years. It's close enough with the right settings...but for some even a TOG T-16 isn't close enough.
The up shot is...the OC-2 digital simulation model in the C4 / Intelligent Filter solves a lot of those problems. It's probably the best OC-2 solution for 98% of users. But I'm sure the remaining 2% will have different views or needs.

This thing is terrifying in its tweakability. But so awesome.

Can someone fill up a C4/DMC controller with presets and then send it to me? ;)
It is actually kind of easy to do this. Go to the Neuro Desktop. Connect the C4. Click on "cloud" and then the search button. Search for C4. Then sort by popularity. Hit the burn button and one by one save all of the top sounds to preset slots 7 through 127. Not quite instant coolness, but pretty good!

Got home from our Saranac Lake gig at 3am and found this on the doorstep. Out the door early for NYC, but should have time to goof with it in a few days... my Neuro Hub shows up on Tuesday.
 
The synthesist in me is highly, highly intrigued by this. It's hard to justify given that I have a Korg Minilogue and an Alesis Micron (which I patch-edit via a sweet PC UI someone designed, so that's not new territory), and I think this would be more than the Micron cost me haha

But having the module right there on the board with all the weirdness I can summon up? It's tempting.

Got C4 up and running 100% with midi switching now. already have come up with a few useful patches that I have worked into live shows.

Man, that's a sweet board. What's the lil sweeper pedal at bottom left?

It’s up to date.

Also just tried to plug it in to my iMac, the app doesn’t see the pedal.
iMac? As in the all in one Mac from
I had that problem with the neuro app not seeing either my C4 Or Spectrum. I deleted the app and Downloaded the app again t6hen restarted the computer and When it recognized the C4 there was a firmware update for it and downloaded that too. It has worked fine since
Awesome. Yes, this seems to be the source of any issues at the moment.
