I'm having a small problem with pan blocks after changing presets. I have a new patch with two lines I want to run in stereo. I have placed a pan block at the end of each line after four delays on each line. Top line has pan block panned hard left, bottom line pan block is hard right. I save the new preset and switch to another preset. On returning to the new preset both pan blocks are now panned hard right. What might I be doing wrong?
