Xpander LFO Rate to BPM conversion chart

Here you'll find an experimental Oberheim Xpander LFO rate to BPM conversion chart.
This was done using the LFO1 Square Wave modulating VCA1, VCO1 vol and VCO2 vol set to 0, VCF Freq and Res to max to have the LFO1 modulating the pseudo sinus of the VCF. As you can see, this is non linear. Some of these values will be used for the predefined values of LFO knobs in Xplorer.
