Soundfont Issue with Piano/Electric Piano

1) Create Piano and Electric Piano (set the mixer's reverb and chorus to full) score.
2) Enter some notes into each.
3) Disable Note Entry and click a note on either the piano or electric piano.

You can hear the last note you played on the electric piano. It's easier to hear this problem using this method, but you can also hear it as you input notes.

Workaround: Change sound font (and change back). However, notice the volume changes too (despite being the same setting).

Using 0.9.6.3 and 10.4.11.
