Can Sample Cell be used with Logics native MIDI driver?
Logic has a built-in MIDI driver for SampleCell. In the Environment window, pick the “New > Internal-> DigiDesign SampleCell” menu-item, and then cable a Multi-Instrument to it. You will still need to have the OMS extension active in your System Folder for SampleCell to work at all. But just don’t make it active inside Logic.
