When MTC input scrubs, sequence plays

[sebescudie]

Environment

• OS: Windows 10
• Version: 1.9.13

Describe the bug When a sequence is clocked by an external MTC source, scrubbing on this MTC source starts the sequence playback, even though the MTC source is paused.

To Reproduce Steps to reproduce the behavior:

1. Create a MIDI module, set its input to a virtual MIDI device
2. Open MTC Sender, set its MIDI Out parameter to the virtual MIDI device
3. In Châtaigne, create a new Sequence, enable Sync Devices and set the input to the virtual MIDI device
4. In MTC Sender, start the playback (Start button) : the sequence playback start
5. In MTC Sender, stop the playback (Pause button) : the sequence playback stops
6. In MTC Sender, move the Time Slider to "scrub" through time : Châtaigne will move the playhead and start the playback. MTC Sender is still paused

Expected behavior When scrubbing on an external MTC source and that source is paused, I would expect Châtaigne to just move the playhead without starting the playback

Additional context Been monitoring MIDI traffic with an external tool (Protokol). When scrubbing, MTC Sender sends a SysEx message. It looks like Châtaigne "interprets" this SysEx message as a play order. Tried a bunch of other things :

• Clocking Châtaigne with another Châtaigne instance over the network using RTP MIDI : same behavior. Scrubbing the Châtaigne timeline starts the playback on the "secondary" Châtaigne instance
• Clocking another tool (Ventuz) using MTC : when scrubbing, it simply moves the playhead without actually starting the playback, which is the behavior I would expect on Châtaigne.

Let me know if I can provide additional details. Thanks!

Can you try the latest bleeding edge ?
