Touché's companion app "Lié" is available as standalone application, and as a VST2 and AU plug-in only. You need a 64-bit host application supporting VST or AU plug-ins to host Lié as a plug-in.
Lié will only host VST2 64bit instruments, no VST effects, no VST3 format.
Hosting AU is not supported. You can use most instruments within Lié inside Logic Pro X nonetheless: Just make sure that you installed the VST format of an instrument on your Mac. You can then use the plugin instrument in VST format within Lié's AU version.
Unfortunately, Logic's internal instruments (Samples, Alchemy, EXS24 etc.) are among the few instruments that are not offered in VST format, therefore they won't work inside Lié.
Lié is also not able to host other proprietary formats that DAW manufacturers use to deliver their onboard synths, unless the manufacturer makes those synths available in VST2 format as well.
You can still use Touché (SE) as a USB MIDI class-compliant controller to work around the VST-only limitation. Without Lié, you can use the inbuilt mapping routine of your DAW to map parameters that don't belong to a VST instrument. Check the respective article for your DAW here.
Stuck note problem on Windows on some machines: Occasionally, applying more complex gestures on Touché leads to a stuck, endless note in Steinberg's DAW. The problem got solved in Cubase 10.5.
Not compatible on Windows: Since Lié as VST fails the Scan routine in Digital Performer, there is no way to make Lié work in DP in Windows for the time being. In a Mac environment, you can use Lié as AU instead.
Not compatible: Maschine, when used as a VST inside a DAW, instead of being used as a standalone application, has trouble coping with the amount of MIDI CC needed for truthfully transmitting gestures from Touché (SE) to Lié. Random CCs disturbing the performance are the result. We currently seek to address the issue with help of Native Instruments (status of June 2019).
Automation issues: Some customers face problems when recording automation from Touché (SE) when Lié is hosted in Maschine 2 Standalone or AU. Maschine 2 seems to have trouble coping with the amount of MIDI CC being sent by Touché (SE). We currently seek to address the issue with help of Native Instruments (status of June 2019).
Not compatible: We don't offer an AAX version of Lié for the moment, so ProTools is not supported. You can use plugin wrappers like Blue Cat's PatchWork as a workaround. However, due to USB MIDI restrictions, this workaround is only feasable for Mac users. Generally, before purchasing, please test if it works on your machine by downloading their free demo (Mac AAX demo or Win x64 demo). You will need to use 'Blue Cat Audio PatchWork Synth AAX' inside ProTools and then load either VST or AU of Lié in any of the slots inside PatchWork.
Not compatible: Reason uses a special way to communicate with external MIDI devices that renders it unusable with our companion app Lié. We have been in contact with Propellerhead: Unfortunately, there is no workaround for this at the moment.
Lié is not tested in non-listed DAWs, but it could work. We cannot guarantee a solution for issues in unsupported DAWs or DAWs with known issues.
Lié itself has no copy protection. Our factory sounds are all based on UVI Workstation, which does use PACE iLok for anti-piracy purposes. You don't need an actual iLok dongle, since its license is directly activated on your computer. The free iLok License Manager is recommended for comfortably managing one's licenses. It will also allow for the activation of additional sound expansions or instruments you might want to acquire in the future (e.g. our Arché Collection). iLok License Manager is included in the Lié Windows installer but is an optional download for Mac users.
