Using MPC Key 61 Plugins on Key 37

Hi,

I have the Key 61, love it but due to size it stays on its stand in the studio (box room). I have just bought the key 37 as I can use it wherever I want in the house and it's great for impromptu ideas, sketch pad etc.

The Key 61 came with additional plugins (Fabric, Fabric XL, OPX-4, Stage Piano etc). Can I use those on my Key 37 and if so how?

I have got my free plugin installed on the Key 37 (I chose Jura).

Both devices are registered to my same InMusic account. After installing Jura on Key 37 I sparked up Key 61, went to Activate Plugins and Jura was there for installation, all good.

Why can't the 37 see the Fabric, XL, OPX-4, Stage Piano plugins which are sat on the Key 61?

I want whatever I do on one machine to be a USB away from being used on the other device, work to be interchangeable.

I understand each plugin can be on 3 devices.

Can someone help me out? DSoundman on YT shows his 37 with these Key 61 plugins and says Key 61 plugins can go on the 37 via this 3 device rule.

I have searched these forums but couldn't find the "how" to do this.

Thank you in advance for your help.

Cheers
