UAD v9.10 introduces Apollo Channel DSP Pairing, allowing bigger UAD plug-in chains on Console inputs by allocating fewer Virtual Channels. The new feature is enabled by default, so you’ll see fewer Virtual Channels in Console after installing v9.10 unless you adjust the new Channel DSP Pairing control.
To view the previously-visible Virtual Channels (including their original plug-ins and settings), simply increase the VIRTUAL CHANNELS value in the new Channel DSP Pairing control in Console Settings>Hardware Panel>Options Column.
