Using a Novation Remote SL 25 on a G5 I always get dropped midi noteon / noteoff messages in Max:

- when more than 3 notes are struck at a time.

When connecting the SL to the Mac over its MIDI out and a MOTU micro lite USB MIDI interface things are fine. Inspecting the SL's MIDI data over USB using MIDI Monitor.app reveals the Novation is doing 100% ok at all times. There is only Max left in the equation.

Novation SL 25, latest Firmware, connected directly via dedicated USB port, no hubs etc.

If you're using notein, it's possible this is a similar problem (bug) to using ctlin with the OSX built-in USB MIDI driver - the max object can't handle multiple messages in the same MIDIPacket. When you switch to a non-Apple driver, the messages arrive one per MIDIPacket.

Sounds reasonable, thanks. How would I switch to a non-Apple driver for a given input device?

Hook it up via MIDI cable to a MIDI interface that uses its own driver (MOTU, Emagic, etc).

Or you may even find that hooking it up via MIDI cable to another device that DOES use the built-in USB MIDI driver will work.

This seems to be a known bug of Max's notein / ctlin objects. Are there plans to fix these basic objects for USB devices?
