List of plugins with problem in sample rate handling
There are some plugins with problems in sample rate handling implementation. In nutshell they are internally fixed to sample rate defined by iOS (device hardware) and they are ignoring sample rate used by host app. Most of current iOS hosts deals with this diplomatic way - they use for realtime playback (and mixdown) just device sample rate (44khz on older devices, 48khz on new devices or on devices iPhone 6S+ when using build in speakers).
You can easy identify such issue easily - just try export project at 96khz bitrate - sound would be distorted with crackles or pitch issues (usually both). Another manifestation of this issue are freezes during mixdown at higher bitrates, or super slow mixdown (like 0.1x of realtime playback rate ). Next known case of this issue is on new iPad PRO 2018, where it is broken even during realtime playback ( Read Matt's comment here: https://www.blipinteractive.co.uk/community/index.php?p=/discussion/comment/5019/#Comment_5019 )
Purpose of this thread is to create list of such plugins. Please add here all plugin where you experience this issue, i will update this first post to have them listed on one place.

(*) Probably still contains older implementation. However based on reports it looks like this issue is present in all VirSyn plugs.
(**) Not tested yet. Please, if somebody owns this synth, try it and let me know. Thanks.
