My fingers would’ve been worn down to bloody nubs in no time with the default settings.
When I first started using the V25 keyboard controller, I found the drum pads required much more pressure than I was expecting to get a full sound.
I recently purchased an Alesis V25, so this tutorial is specific to it, but the same process applies to the other models as well, the V49, V61, VI25, VI49, and VI61. The software is free to download from the Alesis website under the docs & downloads section for each individual model.
