We successfully tested the following apps as "MIDI clock slaves":
- iElectribe Gorillaz
- and the Korg Electribe SX hardware.
DrumJam is reproducably not in sync when using it as a MIDI clock slave with Cubasis as a MIDI clock master. This is how we tested it:
1. Launch Cubasis and enable "Send MIDI Clock" in the setup.
2. Create a new empty project without any tracks.
3. Enable the metronome.
4. Launch DrumJam, enable MIDI Clock input in the setup and configure it to play a drum pattern.
5. Start playback in Cubasis.
Result: DrumJam starts way too late and lags behind Cubasis' metronome.
Since other apps and external hardware is in sync with Cubasis' MIDI clock signals, everything seems to indicate that this is not a Cubasis issue.
As a workaround, use Cubasis not as a MIDI clock master but as a MIDI input by sending the notes directly to the other app:
1. Launch Cubasis, create a MIDI track with the notes you want DrumJam to play.
2. In the Inspector's MIDI Connections panel, set DrumJam as the output port.
3. In DrumJam, clear the pattern (remove all instruments) and enable MIDI input from Cubasis in the setup.
4. Start playback in Cubasis.
4b. If you don't want to hear Cubasis' internal sounds, assign "No Instrument" to the MIDI track.
Result: DrumJam plays the notes written in Cubasis in sync.
