I wish there was a possibility to automate SOLO and MUTE state via Midi CC. It would be sufficient to define a MUTE CC and a SOLO CC, where the values 0..16 activate the channels (and thus activates the mode as soon as a value has been set for one or deactivates the mode as soon as no value is set).
This feature would be a further leap forward to be creative with the limited storage capacity of the drum brute - and that can be automated!!
It would be a nice and especially creative approach to the otherwise very great drum machine and with this small change it would be far superior to other machines.
