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 doesnāt 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 itās currently at. In consequence thereās no way for the MC to know on which preset the Preamp is to adjust itās scroll counter to. Thus the MC will start sending itās 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 itāll start there. Also add a long press scroll message to the MC for up and down, letās 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. (Donāt 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 Iām 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.
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!
I see this thread is quite old but it circled around an issue I am facingā¦ I just want to scroll preamp MKII presets - it is that simple. Just scroll using my MC8. I need to put the MKII under a riser on my board and thus canāt reach the preset button. This seems like such a simple problemā¦ but after a few hours I have not been able to work it out. Any help would be appreciated.
UPDATE: Figured it out. In this example, switch A activates/bypasses MKII, switch B toggles presets in the CURRENT MKII bank up, switch C toggles presets in CURRENT MKII bank down, switch D release event jumps to BANK 2 (orange) on the MKII, long press event jumps to BANK 3 (green) on the MKII, double tap jumps back to BANK 1 (no lite) on the MKII.
One problem remains. It appears as thought PC scroll down and up retain their ācountā (the current number of the internal variable) so that we you switch from one MKII Bank to another, you end up going to the first preset in that BANK (e.g., 0, 10, or 20)ā¦ BUT the first time you press scroll switch on MC8 - you jump to the ācountā plus or minus oneā¦ not from BANK 0, 10, or 20ā¦
A small but noticeable annoyance - if anyone has a way to reset the SLOT value (which is where I assume the count resides)ā¦ let me know.
Iād suggest updating to use the more recent PC Number Scroll function: Message Type List
That has a function to allow reset of scroll counter, so you could trigger that with a bank enter message, for example. Plus, PC Number Scroll lets you use placeholders to display the counter number on the MC which is useful.
