I have a MIDI keyboard connected to my 2i4 via MIDI cables. When I play the keyboard in 32-bit SPLAT, all works fine - playing a note on the keyboard causes note to play VST synth in Sonar and sound to be produced. However, when I do the same in either 64-bit SPLAT or BandLab Cakewalk, no MIDI signal is received. Since 32-bit and 64-bit SPLAT share hardware settings, etc. (TTSSEQ.INI, AUD.INI, etc.), I know it's not a setup issue. Nevertheless, I have confirmed that Focusrite MIDI is checked in Preferences/MIDI/Devices in 64-bit SPLAT (and in BandLab Cakewalk). What could I be doing wrong?
