Hey Obi,
As an IK user, I'm already subscribed to your email newsletter. Which btw was a bit late on announcing the availability of your updated iPad apps. Fortunately, found out about it on my own.
So, no need to spam here.
Which reminds me, I posted some FYIs over in the SoS forums about your Amplitude for iPad app update as soon as it was released.
So, the very least you could do is to offer me free credit on the in-app MIDI upgrade purchase, and maybe on a few fx too, seeing as how I've been doing your job for free.
