Using Multichannel Plug-In Synths
If you load a multichannel VST instrument, such as Spectrasonics Omnisphere, into FL Studio, you’ll find that the MIDI input from your keyboard to the VSTi’s Generator always reaches the synth on channel 1. You can use the Color Group selector in the piano-roll window to assign existing notes to other channels or to enter new notes with the Pencil tool, but if you want to play those other channels from your keyboard while recording (or live), you’ll need to do it a different way.

First, click on the Wrapping Settings button (it looks like a portion of a gear) at the top left corner of the Fruity Wrapper for the VSTi. In the Settings panel, choose a MIDI input port. Next, go to the main Channels menu and add a MIDI Out Generator. In the Plug-In editing area in the Generator box, enter a matching port number and then select a MIDI channel. When you click on the MIDI Out object in the Step Sequencer window to make it active for MIDI input, your keyboard will play whatever sound has been assigned to that channel in the plug-in synth, and a recorded track will play back with the right sound.

Assuming your multichannel synth has multiple outputs, you can map each output to its own FL Studio mixer channel in the Processing panel of the Wrapping Settings window. This gives you complete control over level automation using the standard FL Studio automation controls, which is handy because the volume and pan knobs on MIDI Out Generators do nothing.
