This drum synth sounds great and does allow you to quickly experiment with new sounds.
While there is a step sequencer, this only manages patterns and not songs. So its impossible to use this application to create a backing track, you have to switch patterns yourself, which is annoying also since they change instantly instead of on the next beat. Theres also no way to change patterns through MIDI messages, meaning that pattern changes cant even be automated through another application or foot pedal.
Everything is focused on sounds and snapshots of these. You cant store or load individual patterns. The sound sculpting sadly also lacks a number of fundamental effects like delay and reverb.
Finally, tap tempo seems to be missing, which is really strange for a drum application.
I like the application and currently record individual patterns as audio inside Auria, and manage songs like this. It is a very cumbersome way to approach this though, but the sounds are good enough to go through this effort.
