Are there any quad channel motor controllers?

Last year I was on a robotics team that used a dual channel Roboteq motor controller to control two motors which controlled 4 wheels on the mobile robot (some kinda drivetrain idk I'm not a mechanical).

This year on a different robotics team we are designing a new robot but basically the same idea, except we will use 4 separate motors (no mechanicals on this small team and we're a bit short on time) . Now, I was wondering if there are any quad channel motor controllers with similar or comparable software to Roboteq, or if I'm stuck using 2 dual channel Roboteqs?

Unfortuantely, the most ammount of output channels we offer on any of our products is 3, and that is only for Brushed motors. However, using RoboCAN to combine our controllers lets you call motor commands on both units from a single controller. This is as close as you are going to get to a quad-channel output controller.
