I have both the 64 and 32 bit versions of Cubase 6.5 (fully up to date) installed both on my laptop and on my desktop machines. The set-ups on both machines are (or ought to be) identical. The MIDI input problem which I am about to describe is common to both machines although the Scarlett hardware set-up applies only to the laptop set-up.
I am using an old Casio keyboard with MIDI in/out capability as my MIDI controller. I am using a Focus Scarlett 18i6 USB as the audio/MIDI interface between keyboard and laptop. I have the latest versions of the Focusrite driver and software installed. I have got everything working fine in the 64 bit version of Cubase. The keyboard is happily driving VST instruments such as Halion and I can hear, record and playback through the M-Audio monitors connected to the Scarlett.
It is a different story with the Cubase 32 bit version however. Although any existing MIDI tracks play back fine, and although I can hear input from the integral keyboards in Halion etc, I cannot hear any input or record any MIDI tracks using the keyboard as input controller. I can see from the Transport window that input from the keyboard is reaching Cubase from the Scarlett’s MIDI port, but for some reason that input is not reaching the armed Cubase track.
I should say that recording/playback of audio tracks seems to be fine in both versions. I am routing live instruments and vocals to the Scarlett inputs via an oldish but still sound Mackie mixing desk (plus a Sampson DI box in the case of guitar and bass tracks).
Any idea what the MIDI problem is with the 32 bit version of Cubase? So far as I can see all the settings are the same in both versions but for some reason the 32 bit version is receiving but not passing on to a track, the input from the MIDI port on the Scarlett. I am reckoning that it must be an internal Cubase issue – either an incorrect setting on my part, or a software glitch. Am I missing something obvious?
All help and advice gratefully received.
