I’ve not been good at maintaining the tl.objects for the last few years. The functionalities that I use myself have mostly been reimplemented in Jamoma. If you’ve used the butterworth filters, you might want to check out jcom.filter~. This is a filter swiss army knife with all of the Butterworth filters implemented and much more. If you own Tap.tools the same object shows up there as tap.filter~.
Still I know that tl.objects are still used by others.
A few weeks ago I received a mail from Francois Eudes Chanfrault. He has been kind to recompile the tl.objects externals for Windows. They’re now smaller and better optimized, and are also checked for Max 5 API compatibility. I really appreciate his efforts.
The new version for Windows can be found here.
