Needs another update ASAP

The one time this app worked without crashing
on iPad Air 2 it was fantastic! Wonderful arp, great randomization tools. Etc
BUT after that, even after reinstalling IT CRASHES EVERY TIME I try and assign midi in
and out. PLease update, as I love your apps
and would give this one five stars if it just worked

Poor External ClockSync, Transport Stop/Start, MIDI controls

👯 it's just like the arpeggiator section for all of other Virsyn synths. Right now, it literally feels like one of their other synths that's been gutted with only the arp section remaining. It's a decent arpeggiator, but needs improvement with control and interoperability with other MIDI gear. ⚠️

🎹🕤🚫🕜🎹 Unfortunately🙇🏻, as far as I can tell, there's no apparent control for external ClockSyncing and no reliable way to trigger transport Stop/Play from other apps—so one must wonder, 'what's the point?'

Musicians who like Virsyn instruments will probably not be not be disappointed 🔜 when the devs do eventually release an update the problems I've mentioned, but for now this🌱 1.0 release has limited functionality.🚼

If you have StepPolyArp by Laurent Colson, you probably do not need this unless you prefer the arpeggiator control interface of VirSyn's synths.
