I'm not getting consistent values from midipitchbend when trying to
read from my MIDI keyboard's pitch wheel. The returned values are
always between -1.0 and 1.0 but I'm not sure what range it's supposed
to return. The value goes up when I roll the pitch wheel up, and down
when I roll the pitch wheel down, so no problem there. The problem is
the value max and min are not constant. If I roll the pitch wheel all
the way up, it'll read anything in the entire range from -1.0 to 1.0.
Same results when rolling the pitch wheel all the way down.

I can't seem to figure out a workaround in cabbage for it. I've tried
using the midiin opcode in an alwayson instrument, but that doesn't
work in cabbage for some reason.

Can someone take a look at the midipitchbend opcode and make sure it's
working correctly?

Thanks,
Andy Fillebrown

This appears to be a bug in Cabbage.

The output of the midiin example is correct in CsoundQt, but the same
.csd in Cabbage produces the following output when the pitchbend wheel
is used...

It looks to me like the MIDI data is not being parsed correctly for
pitch bend messages in Cabbage.

I'm on OSX using Cabbage(32bit) v0.5.13 Alpha.

All other MIDI controllers are working correctly in Cabbage.

Cheers,
Andy Fillebrown

I found the MIDI pitch bend bug in file CabbagePluginProcessor.cpp,
function ReadMidiData...

It should be something like
...
else if(message.isPitchWheel())
{
    const int pitch_bend = message.getPitchWheelValue();
    *mbuf++ = (unsigned char)0xE0 + message.getChannel()-1;
    *mbuf++ = (unsigned char)(pitch_bend & 0xFF);
    *mbuf++ = (unsigned char)((pitch_bend >> 8) & 0xFF);
    cnt += 3;
}
...

instead of
...
else if(message.isPitchWheel())
{
    *mbuf++ = (unsigned char)0xE0 + message.getChannel()-1;
    *mbuf++ = (unsigned char)message.getPitchWheelValue();
    cnt += 3;
}
...
