Hey all. I have a Walrus M1 that I’ve integrated into my pedalboard and control with my MC8. Before I go hog-wild setting MIDI commands up, I’ve been trying to cover the basics: turning the unit on & off and selecting certain presets.
Selecting presets is easy - it’s just sending PC messages with the correct preset #. Unfortunately, activating and deactivating the bypass switch is wonky. Per the user manual, I operate the bypass switch with CC#31, value 0 = bypassed, value 127 = engaged.
I set up a button on the MC8 in toggle mode labeled “on/off.” First press is programmed to send value 127 to CC31, second press is programmed to send value 0 to CC31. When I actually press the button, it activates the FIRST time I press it. Then I press it again, and nothing happens. Then I press it again and the unit turns off. Press a 4th time…nothing. Press a 5th time, unit turns on.
I can’t figure out how to make this work as it should: every button press turns the unit on or off. Please help!
Suggest posting a screenshot of your preset and/or export the preset as json and attach here!
Thanks. I’ll do that next chance I get.
Also if there’s a link to / screenshot of the available MIDI commands on the walrus post that too (though, guess it might be in the midi dictionary, haven’t checked!)
Alright - I figured out the on/off issue. It had to do with the toggle setting for the ‘press’ action not being assigned to the correct positions 1 and 2. Doh!
So now I can turn the unit on & off as desired, however, my next challenge is controlling the effect speed with my expression pedal. I have an expression pedal connected to EXP 3 omniport (with the omniport correctly configured). Here’s a screenshot of the setup for Expression 3.
CC Number 3 controls the pedal’s RATE (ie speed) parameter so when I move the pedal up & down, it should adjust the effect speed. Unfortunately it doesn’t.
I also have the MC8 sending MIDI clock to all my units via tap tempo. Is it possible that this is overriding the expression commands? If so, how do I prioritize the Exp over the tap tempo clock?
Here’s the Walrus M1 MIDI detail
It’s possible to turn off ‘Midi clock persistent’ in the general settings of the MC.
To actually use an Exp preset within a footswitch preset, add a msg that selects the expression preset, action Press, position 1. If you want to deselect that Exp preset then you could add another msg, Press position 2, to deselect Exp preset(s)
If I turn off “persistent,” does that mean that the MIDI clock only sends time data when I change the tap tempo?
I don’t follow what you’re saying. I simply want the EXP pedal to increase/decrease the speed of the effect. Would it be easier to make the EXP pedal change the speed of the MC8’s MIDI clock? Then I don’t have to try and tie the EXP pedal to a specific effect unit’s MIDI messaging.
PS - I originally set the expression pedal’s messaging up exactly as shown in this video: Using an Expression Pedal together with MIDI - Morningstar MIDI Controller - YouTube
It will stop sending midi clock, if you select a different preset.
