Faders - Reversed Polarity (Hammond Org. emulation

Design Concepts
1

Hello

Does anyone know if there is any way to reverse the polarity of the faders (so that when the fader is fully up the value will be 0 and when it is fully down the value will be 127), without changing the connections in the hadware? Is there (or could be) an option in the software, a special mode (i.e. “reversed mode” like “parallax mode” etc.). If this could be done the MidiBox64 (and generally the MB) could undoubtedly become an amazing Hammond Organ emulation controller (I would like to use it with Native Instruments B4) 8)

Thanks in advance

Dimitris

Should be easily done with MIOS.

Just send (127-(PotPosition)) instead of the normal value and you have it.

Thank you vm!!

Can this be done only under MIOS (I will be using the old PIC16F877 in my midibox64… the 18f452 is impossible to find in Greece at the moment) ? ???

Try http://samples.microchip.com/ they’re free and I don’t see why they wouldn’t ship to greece, my 18f were shipped from thailand to the uk.

Btw.: with the MIOS based MIDIbox64 this can be realized by swapping the Min and Max value. This means: when you set the min value to 127 and the max value to 0, the fader value will change in the reverse direction.

This feature is not provided by the PIC16F based version.
