Hi SMers

testing the new ( beta ) Pitch bend module i got surprised for the range out

If i remember ok ( not always easy at my age) MIDI spec says that Pitch bender Msgs values come into TWO bytes ranging from -8192 to 8191, ( or 0 to 16384 with zero bending at 8192, not sure)

What is the reason for using an integer range of 0-255 for it?

That's wouldn't be important except for that this small range seems to be causing audible freq jumps when you try to bend for example, a full octave (see my example in example forum if you feel that i'm talking Klingon 😀 )

Hi unkargherth,

Yeah, you're right. I was only using one of the two bytes that are provided. By combining the two you get a value that runs from 0 to 16384.

I'll get that fixed.

Malc.

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
