This thread is solely to list plugins we have found that migrate in Komplete Kontrol (and obviously also Maschine) as a resource for this community. It is not for support or complaints about stuff that doesn't work so please post such comments elsewhere. I just thought it would be useful to keep track of plugins that migration works for; over time I am certain more will be available as developers come onboard.
What is this 'migration' you may ask? Basically as VST2 as a format is gradually being phased out, and on Intel Mac is not (officially) supported at all, there is a framework in the VST/VST3 SDK to enable DAW projects and things like NKS patches containing VST2 plugins to be able to automatically substitute the VST3 version of that plugin when it is on the same system. This requires support at the host level, and Komplete Kontrol and Maschine have that since the last version, and support by the plugin, and this developers need to implement. If that support is not available in the plugin you will get the error message reported here. Many have already (some seem to have done so years ago like SPC Arcsyn) but there are also many who need to update their plugins to support migration. So far in my tests I have found the following plugins/developers support migration for NKS patches in KK/Mas either fully (NKS presets load correctly in the VST3 version with params intact) or partially (NKS presets load correctly in the VST3 plugin but with errors in param mappings):
All NI plugins that exist as VST3
All AAS plugins (apart from Multiphonics but that has an unofficial NKS version in the NKS User Library)
All SugarBytes plugins migrate (not all are NKS though)
Plugin Alliance plugins that support NKS (eg Unfiltered Audio, bx Oberhausen, Knifonium and Thorn)
iZotope plugins
Expressive E Imagine and Noisy
Modartt (Pianoteq)
Synthmaster One and 2
112db Micron plugins (eg Mikron Cascade)
KORG Legacy series (all except the Tritons and MiniKorg)
Vital
XFer Serum
UVI (Falcon and Drone - I presume also UVI Workstation, now tested Relayer too so I suspect they all support migration)
TAL MOD (only TAL plugin I have tested)
SPC Arcsyn (migrates VST2-3 but not AS native yet)
Audiodamage Quanta and Discord I tested working, Phosphor however didn't work and Quanta 2 is now only VST3
Valhalla dsp plugins (but with incomplete migration of automation params)
All Overloud effects (including now SpringAge)
Eventide Blackhole, Ultratap, Instant Phazer II, Instant flanger (probably all except Newfangled Audio)
Audiority Grainspace and Xenoverb
Soundtoys
Audiothing plugins
Tracktion plugins F'em and Biotek 2, MOK Waverazor (so possibly all by Tracktion)
DiscoDSP Discovery Pro 7.5
SonicCharge Plugins
u-he plugins (maybe Mac only for some)
Cherry Audio Voltage Modular (from 2.7.0 and param mappings don't migrate only the patch)
LennarDigital Sylenth 1
GForce OB-E (but not SEM or imPOscar 2)
Arturia instruments and FX
Synapse Dune 3, Obsession and The Legend (Mac only)
Output plugins
Sonic Academy ANA 2
XILs-Lab - Poly KB II and III, XILS 4 and Poly M
Disclaimer: my system is a M1 Max Mac so that is no guarantee the same would be true on Windows but in most cases it should be - however I am aware plugins on Windows and Mac do sometimes have different plugin names
Also note this is just plugins that load the NKS preset made with a VST2 version into the same VST3 - we have noticed in some plugins params may need fixing as there are discrepancies between some VST2 versions and arrangement of params in the VST3 - again that is on the developer ultimately as they should be consistent - so far this seems to be the case for Valhalla and Korg Legacy plugins - however it isn't too hard to fix these anomalies and I have already posted a fix in the NKS User Library for the Valhalla VST3 plugins
Anyway, hope this thread is useful. It should be in particular to anyone considering whether they still need the VST2 version on their systems if they have the VST3 (which is also more likely on Mac Silicon, to be native)
