How to deal with toggle/non-toggle CC button?

Question

I have a plug-in with a parameter that responds to a CCxx Value 127 to turn on/off. However it has to receive a Value 0 before it will then respond to the next Value 127.

I'd like my control button in MD to toggle this value on/off. And I'd like this button to light to let me know the current state of the parameter.

I can't find a set of parameters in MD that permit this. I can't use 'Toggle', since then I have to press the button twice, and I can't use momentary, because then the button doesn't toggle.

I'm stuck for a way to do this!

So it needs to receive 127-0 to toggle ON and 127-0 to toggle back OFF? I think you can do this with more supercontrols and subcontrols. For instance, a button sub can be "send on only" and then send a 127 or a zero. So you could make a supercontrol send a lot of values on each press (this is a rough idea, of course). You could also do this with Stream Byter.

Thanks. Yes, I've managed to cobble together something using a Supercontrol and 'Send On Only' for two buttons.

Each Sub-control is sending 127 and the Supercontrol is sending 0 and set to 'Vintage Throttle' (since the recipient was ignoring it otherwise). Even so the results are not consistent.

So this does kind of work, but... I have no way of flagging a change in the parameter received from elsewhere, since I have identical values for both buttons.

Supercontrols should never send, Elf. Avoid using supercontrols send own values! Make more controls.

I've had to resort to this on a couple of occasions. I don't like it, but it's been a necessity.

Think we solved something like this recently.  But my memory recall is slow - queued up now, lets see if it will remember before the eclipse.

Thanks. This is a toggle to set forward/reverse on a looper plug-in. Hopefully it makes some sense in that context.

Answer 1

To check, you need to to send Cc xx 00 Cc xx 7F to toggle state either on or off.

Solution 1: Make a knob, MIDI is desired Cc channel & number, named ticks, three ticks, values are 127, 0, 127

Make a button, toggle, no send / receive, supercontrol of the knob, options as super - snap to value.  Start at 10ms and adjust timing as needed.

Solution 2: We can also trap in StreamByter, change any instance of Cc xx to the 00 7F sequence, esp now that Dan has fixed delays.

Something like:

If M0 == B2 32 # desired Cc and channel here
   SND B2 32 00
   SND B2 32 7F +D100 # Adjust delay as needed
   Block
END

Awesome. How many solutions are listed here? Two, or three? Thanks.

Thanks!

I should have come up with the SB solution myself. You can get so close to a problem that all common sense thinking goes out of the window!

The super-control solution... I need to think about that one. Err...

No joy with any of the above. I've arrived at a completely different solution - change the looper!
