shadowcomposer Posted April 2 Share Posted April 2 Anyone happen to know how to go about making a transformer to invert played pitches around middle C? So a D played above middle C would trigger a Bb below middle C, and so on? Quote Link to comment Share on other sites More sharing options...
Frances O Posted April 2 Share Posted April 2 While there may be easy ways to do this - if you want to use an Environment Transform - One way would be to map notes to invert pitch: 1 Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted April 2 Share Posted April 2 @Frances O the routing is correct but the transformer isn't set to invert around middle C. This transformer would work to invert the pitches around C3: 1 Quote Link to comment Share on other sites More sharing options...
Atlas007 Posted April 2 Share Posted April 2 Wouldn’t the result being the same? Quote Link to comment Share on other sites More sharing options...
Frances O Posted April 2 Share Posted April 2 The result depends on two different meanings - Middle C is MIDI 60, but Middle C might be C3 or C4 etc as naming conventions are not always the same with instruments. The OP wanted a Middle C inversion. David's approach with 'Flip' is much simpler to implement than my mapping. I did set my transform map to invert around MIDI 60. But my example was from a keyboard I have that uses C4 as Middle C. So the Transform Map inverts around C4 as seen in the Monitor objects. 1 Quote Link to comment Share on other sites More sharing options...

My apologies, I saw your map and I saw 127 mapped to 0 and concluded that you had simply inverted the map (without offset) which wouldn't have been a inversion on MIDI note #60, but I see now that the map was offset.

Frances O Posted April 3 Share Posted April 3 Apologies David - I did't mean to sound like I was correcting you! I had been unclear with my original answer - and my pic only showed the last note offset data - which was no help. I was fixing my original answer for the OP that the inversion needs to happen on MIDI Note #60 for Middle C. 1 Quote Link to comment Share on other sites More sharing options...

Oh yeah and I suppose mine should flip around C4 (and not C3) then to invert around MIDI Note #60. I'm a guitarist, so "middle C" has always confused me. 🤣 Quote Link to comment Share on other sites More sharing options...
Frances O Posted April 3 Share Posted April 3 It can get confusing with Note+Octave naming conventions not being directly tied to the MIDI Spec. MIDI Note #60 could sound any played note depending on what settings/tunings/offsets you have on an instrument patch. I always have to double check as I have multiple outboard instruments that all have different names for Middle C, most usually C3 or C4. The OP will need to determine what their Middle C note is named by LOGIC and use that name in the 'FLIP' Transform. LOGIC sees my KORG keyboard C4 as MIDI #60 (which aligns with Scientific Pitch Notation, or approx. 261 Hz in A440 Tuning). 1 Quote Link to comment Share on other sites More sharing options...
