Hi,
This is what the manaul tell under Import:
"Import: This command lets you import a preset file, which can be either a single
preset or an entire bank of presets. You can also import a sound as a Sysex file
from the original SQ80, and use it inside this plugin. This way, you donīt have to
carry around the hardware synth anymore."
So it look like it can import sysex files from the original SQ80. I have'nt tried though.
