I'm almost finished my modular MIDI Controller software for iOS/iPadOS. I am hoping to offer a good compromise between ease of setup and power. Hopefully I get this is on testflight in about a week or two. Best I can share is some screenshots right now: https://imgur.com/a/s80g0Iv

Really hoping to do this right as an indie dev with a good website, video promotion, marketing, etc. Probably free but with a one-time IAP for unlocking features. Worst case scenario this helps me land new jobs :p
