If it is a specific topic that you want to discuss about a specific Rytm feature or capability, by all means, start a topic. There are plenty of MKII threads in the Rytm section already, covering the dual VCO synth, the new sampling workflow, etc.
If you’d like to join the conversation about the news that the Rytm MKII is now shipping, there is a lively thread already at Analog Rytm MKII is now shipping
You wouldn’t get scolded if the thread was redundant or unnecessary. Your post would be merged with the appropriate topic, in order to keep the conversation centralized for those seeking information on specific topics.
