Yes, you can run the large template with monosequencer, but will need to delete a native ableton device template in order to make room for the monosequencer (the large template uses all of the avaialable memory on the lemur). Each template inside the large template is inside a container, which is named after the corresponding device. You might want to delete the “Collision” template, because it’s quite large and not used often. So navigate to the container called “Collision” (which will be inside a numbered tab). e.g.
Delete the whole container called “Collision” and save the large template.
Now you should be able to load the monosequencer and any other large templates. Max Devices and VST will always use send template mode regardless of whether the “switch template” mode is selected or not, but the Ableton native devices should at least use “switch template” mode
If this is still not enough you might need to delete another template – but that should be more than enough.
We might make it so you can design your own templates to be inside the large template soon.
Hope it helps.
