Send me an email at mpercossi at zenaud.io , always fun to talk to fellow audio devs :)
And for all the vim lovers out there -- my app supports vi commands for movement and editing :)
Indeed, I'll go further. I'm really starting to believe that the only way not to get royally screwed as an app developer is by abandoning the "major" platforms -- which all want to turn you into a serf -- and target OSS platforms like Linux. I'm honestly tiring of dealing with the artificial roadblocks Apple (and Microsoft is no better) throw at me to further their own ends. I actually analysed SteamOS with this intent, but sadly it looks like SteamOS is geared towards the "living room" experience.
Anyway, long story short: there will be Linux support in 2018.
I realize this is a big limitation, but we intend to add a piano roll in the next few months.
