There are many Factory FX Chain templates that can be found in the 1600 bank as seen below. The 1609 template I have highlighted gives you 4 algorithms in parallel, though you will need to route the hardware outputs of your FX Chain for your workflow and setup.

More algorithms per FX Chain is not a simple UI update. The H9000 uses 4x quad core ARM DSP processors. There are 4 algorithms per chain because there are 4 cores per DSP processor; each algorithm runs on a core.

Allowing more algorithms per FX Chain is not a simple task, thought it may be something we can add in a future update. I cannot provide any guarantees or timeline for this.

The Gen2 DSP processors allow for more powerful algorithms to be run per core, and our focus for upcoming releases is more powerful algorithms that take advantage of the new processors.
