Well mapping samples to key is something that you can get from the manual, it will take some page swinging but you cab at least get it.
But from there, you get into round robin, zones, layering, voice groups, zoned voice groups, etc. this is where you have so many factors and it is hard to wrap it all into a package in your brain to actually sit down and complete a full featured drum sampler.
I’m looking to stop making music for a few weeks and focus on just creating HALion projects and just using the manual PDF shortcut everytime I get stuck. Currently have the pdf on my phone and get 10 pages per day on the train, but this is going in and out of the brain.
