Hi,
For some reason loading a Room EQ preset on one channel is affecting the Room EQ preset on other channels.
In ths video I have the Soprano Choir and Alto choir both with the Soprano choir Room EQ preset. I load an Alto choir Room EQ preset on the Alto choir channel, now the Soprano choir channel has the Alto choir Room EQ preset loaded also.
p.s. The Room EQ needs some work. Namely, undo/redo and drag over all nodes and maybe a spectrum display.
