I am in the midst of my first setup of the MC6 (MkII) controller with my board (Preamp MkII, Walrus M1/D1/R1 being controlled) and have encountered a problem that I have been unable to find a solution for so far.
On the Preamp MkII, I would like to setup a Press function (one switch for up, one for down) to allow scrolling between presets on the pedal where the scrolling starts from the current preset/PC position. For example, if I am on a preset in Bank 1, position 5; when I press the scroll up switch I intend to move to Bank 1, position 6 and so on, up and down. Currently, I have only been able to have the first press of an up or down PC Number Scroll or PC Scroll Up/Down, it advances to the lowest number in the counter before beginning to scroll up or down, and then it keeps its place, even when a PC message is sent to move to another preset. For example, if I am on Bank 1, position 5 and I press the assigned PC scroll switch, it will first advance to the lowest number in the counter, and then proceed to allow up and down scrolling.
Is it possible to have the scrolling begin from the current PC position on the pedal? I imagine it as a PC+1/PC-1 kind of message, but there doesn’t seem to be a way to set that up?
Happy to provide any additional information or a more detailed description.
Edit: Wanted to add that in the CBA midi deep dive video on youtube, Joel shows this action happening with an MC6 MkI, so it seems like it should be possible?
Thing is, the Preamp will not send any MIDI Information to the MC about on which preset it‘s currently at. In consequence there‘s no way for the MC to know on which preset the Preamp is to adjust it‘s scroll counter to. Thus the MC will start sending it‘s first PC message from the start value given in the scroll counter settings.
You could set the start value to your favourite Preamp preset, so with every power up it‘ll start there. Also add a long press scroll message to the MC for up and down, let‘s you scroll very quickly while resting your foot on the switch.
What might work is to add a update scroll counter message to every preset on your MC that recalls a preset of the Preamp. Say you recall preset 3 on your preamp by sending PC 3, update the scroll counter to 3 in the that preset of the MC.
edit: Yes it works, see screenshot attached. (Don’t mind that the Scroll counter Number and Midi channel are both number 2 in my example, they have nothing to do with each other, I just like to keep things tidy as I’m controlling 12 MIDI pedals with my MC8.)
Just wanted to post here an example of my page that is scrolling thru the presets of the Preamp MKII in case you were interested.
Buttons B (PcDnSd) and F (PcUpSd) scroll up/dn while sending the PC at the same time thus changing presets. Buttons D (PcDn) and H (PcUp) just scroll the counter, the PC has to be sent then by button G (PC send).
I use this to jump to desired presets on the Preamp and use the same page layout to save presets on my other CBA pedals which have no preset display. You know, you dial in a sound, then you move the counter with D or H to the slot you wish to save it in. Hold both switches on the CBA pedal and hit G (PC Send) to send the PC and save in that slot.
Example for button F
Thank you for this thoughtful approach! I think your suggestion will work for me!
The real world scenario is that I have songs where I want to toggle between drive presets; first part of song is clean preamp, then a solo with an overdrive setting, then a gated fuzz part, then back to the clean setting. So for instance, PC 4 is clean, then PC 5 is OD, then PC 6 is gated fuzz; so I send a PC change to the Preamp MkII and the Walrus pedals for PC 4, the I only want to adjust the PC on the Preamp MkII from there using the Up/Down assigned switches.
I was thinking of a work around where I setup a counter for each song and then manually enter the PC range for the Up/Down scrolling (in the case above 4-6), but i think your solution is more elegant and will make it easier to copy this preset to other banks without having to manually enter the PC range for each song.
I will try this out tonight when I get home and report back. Thanks again!
UPDATE: @kyuss the suggestion worked a treat! Now if I could just get these Walrus pedals to accept CC first time every time
Wow this is awesome. Just commenting for later reference.
