Can the transpose range for the Vortex keysplit mode be extended past -12 to +12?

I've set up keysplit on 2 channels with a bass synth on low and lead on high. Even with bass transpose to -12 and lead +12 the range isn't wide enough, id need +24 on high split to be useful. Any reason such a small range is allowed and can this be extended?

  • Can't do more than 12 semitones. What software are you using? The bigger transpose can be done as the midi signal comes in. If you're using a synth, some can do it.
    There are also hardware solutions (midi solutions has one)

  • I'm not using software; none of the hardware synths I'm using allow transposition of the incoming MIDI messages on a per-patch basis (I'm using a Moog Minitaur, Prophet 08 and Roland Fantom G8).

    The Prophet and Fantom do have a global Transpose but that's impractical in a live situation. I had a quick look at the Midi Solutions options, but that doesn't seem workable either - I don't think I can send a program change from the Vortex to selectively enable/disable this shifting, so again not practical for a gig situation.

    I guess its not quite "transpose" I need but the ability to shift octaves separately on lower and upper splits. Just to expand on the initial description: To get a low C bass note on the Minitaur played from the lower split I have to hit octave shift down oncee, then also transpose to -12. I then set the upper range to transpose +12 but my top C is still an octave too low to be in the correct range for a lead instrument.

    Best workaround I've come up with now is to modify the actual patch on the Prophet and shift the oscillators up an octave, but it feels like a controller limitation that might be easy (?) to improve in a future firmware update if there was one planned.

  • On this page: http://www.midisolutions.com/chapter1... , the "mapping" section explains how to do this. When you split the keyboard on the Vortex, you can assign a channel to each section. You then just have to map that channel in the Midisolutions Event Processor. I'm sure that each of your synth can choose an incoming channel (I hope so). Then there's no need to send a program change. De-splitting the keyboard will bypass the mapping. This section http://www.midisolutions.com/chapter2... explains how to transform a range of values using variables.

  • Thanks for the suggestion. Given that the Midi Solutions box is almost the same price as the Vortex I'll stick with my oscillator pitch workaround for the time being!..
