I found the same to be true with my Sonic Cell and Tyros combo. I can layer the Tyros' R1, R2, R3, and Left voices with the Sonic Cells sounds of the same category (bank) in Performance Mode and of course choose specific sounds from other banks, whether GM, Preset, or SRX expansion cards if preferred. I can also turn off local control for R1 on the Tyros and play just the Sonic Cell sound in Patch Mode (part 1) and then layer R2, R3, and Left voices of the Tyros to create rich layered sounds combining both the Sonic Cell and Tyros' sounds together. The Master volumes of each can be adjusted to give you that perfect blend of sounds from each one and there is also the volume adjustment of each of the individual tracks that can be adjusted as well of course. There is also the option to route specific parts out through either the Main Outs or Sub1/Sub2 outs of the Tyros and the possibilities expand even further with the other set of Tyros MIDI In/MIDI Out ports.

I can do the same with the Style parts and the Tyros' Multi-Pads too. Also, when playing a 'song' through the Tyros the sounds are played back through the Sonic Cell in Perfomance Mode and can utilize up to all 16 tracks of the Sonic Cell essentially doubling the effect and also adding additional nuances while at the same time enhancing the songs sonic palette and capability in my opinion.

Here is a song demonstrating the effect. Note: This song has only "10" tracks but I still think you will get the idea.

PS: One for you Aussies!

BTW, I think the Ketron SD2 is a great bang for the buck sound module and also an extremely portable sound solution.
