You’d need to ask Janek - he loaned Dunlop his OC-2 while they did the development work. My guess is they studied the components and did oscilloscope tests to compare the sounds. I wouldn’t always trust a company to know their own products - Selmer famously lost the blueprints to their beloved Mark VI saxes so that when they made the Reference series in the 2000s they had to track down good examples and reverse engineer the shape and metallurgy!

The MXR vintage bass octave is closer as it’s a direct clone of Janek Gwizdala’s OC-2.

I’ve had mine in order from BD since December. Yes, the MKII has one and I used to own one; sold it a while back (and regret it) when trying to be sensible about the number of octave pedals I needed. I’m happy to have it in a smaller box in the MKIII and it purportedly has slightly improved tracking (we'll see, if it ever materialises). Unless I’m being unusually dense today, I can’t think how the LS-2 would allow you to go from dry+wet to wet-only using the stomp switch - you’d have to go from A to A+B mix, which would require bending down to turn the knob to the new position. You could potentially do it with the OC-5 and LS-2 as follows (provided the OC-5 dry out jack is independent of the direct volume knob - is it?): Plug OC-5 output into LS-2 input. Set OC-5 to -1 octave only. Plug OC-5 dry output into LS-2 A return and set it to A+B mix. What should happen is that when the LS-2 is bypassed, you get the OC-5 wet only (provided it is engaged). When engaging the LS-2, you should get OC-5 wet from the input (this happens if nothing is plugged into B) and dry signal from the A. (You might need to plug a dummy jack into the A send as I can’t remember if it is the send or the return which has the switch in it.)

If it weren’t for the fact I want a dry kill switch, I’d probably cancel my Octabvre MKIII order and just get this. (I might get one anyway.) @Al Krow what did you pay for yours?

I think I remember reading in the marketing bumpf that it did indeed utilise the SY-1 tracking circuit.

What FI firmware? What Editor version? What MIDI channel is your FI set to receive on? Have you downloaded the latest UM-One Mk2 driver from the Roland website? Have you got the in and out cables plugged into the correct ports? Are you putting the FI into update mode when attempting the update?

Aha, now you mention it, I believe SA reference his work.

If you have a MIDI controller you can do this via CC messages as the entire MIDI implementation is publicly available.

Multiband distortion was a new thing when Source Audio introduced it with their Soundblox 2 Multiwave Distortion pedals. Pretty sure that was after bit crushers.

He may have meant my video-chat lesson; the link to the text for the tutorial patch I shared is in the description box of the patch itself.

That’s very kind of you, thanks. I’m in Sheffield. I’d be happy to give you a lesson or two on the C4 to return the favour. (I did this for @dodge_bass via video chat and it worked reasonably well.) Here’s my tutorial patch: https://neuro.sourceaudio.net/preset/DyV1RQhBhF

If you want to do it without extra gear then Source Audio’s Dual Expression plugs straight into the control port. Do you already own a MIDI switcher and have something that can act as USB MIDI host? If not, you’ll need to get one in order to access presets 7-128. I’d recommend getting the SA Hub and a Morningstar controller. There are other options from Disaster Area which do simple preset switching, a few programmable MIDI commands and act as a host. Both the above allow you to plug any expression pedal into the controller and send signals to the C4.

Check out Zach Rizers walk-through of the editor (video on YouTube). I’ve made an instruction template tutorial. There’s a patch with a link in the description to a text-based tutorial which explains a reasonable amount of the essential controls to get you started. When downloading others’ sounds, remember that you’ll need to adjust the input and output levels to your instrument and resave it, otherwise it may be overly loud or quiet. Octavius Squeezer is a pedal I’ve always wanted to try (though it looks like a pain to program).
