Transforming cc73 -> C#0

Greetings all-
Clunky software does not accept CC messages for modulation. Only low keyboard notes not on midi guitar.
I have found transformer to be one of the most challenging tools. Although I have tried, apparently I need step-by-step help on making this transformation. [ cc73->C#0 ]
It never seems to come out right.
Thank you much!

OK, here’s a quick step guide


Read down the purple Input boxes first, seeing what they point to

then study the blue Output boxes.

here’s the patch with a few filters so that Only CC#0 is allowed out with a matching Note Off .

To get a really solid understanding (and to make it fit your use-case precisely!), I’d suggest changing one property at a time and watching MIDI monitor closely.
pje_CC_to_LowNote.mhp

Gotta dash without testing, hopefully I haven’t made any silly errors.

Thank you for the detailed explanation that helps me understand.! I change the channel to number one, and it worked !

Anyway, now I want pedal up send C0 to return to my original state. I thought this would work modeled after your patch, but it doesn’t (disregard the octave transposition.

I wrote a whole bunch “If this, then that” stuff, then removed it cos I noticed you’d only included the Transform in your patch.

What happened with Length pipe in place (giving a Note Off very soon–5ms–after the Note On)? Did it stop it working or what?

Please paste in the relevant part of the MIDI implementation part for the device; it’s not clear why you’re you’re using C1 to switch off.


Be aware that Note On, velocity = 0 actually sends a Note Off message.

So you might need this as your Transform2

(note the changes to 3 of the properties, making this Transform Replace CC73, v=0 → Note On C1 vel=127)

(you should also change the original Transform so that Value in Range Low = 1 or 64 ie. v > 0)

I tried your suggestion and it works.
Unfortunately, the primary purpose of the patch, which is to change from channel one to channel 2 on pedal down (sustaining channel one) and then returning to channel one on pedal up with all notes off to both channels.-no longer works.
I tried putting a filter in so only notes would pass through the two new pipelines on the bottom. But that did not help.hmmm
