Hi @Francecorre, in your sequence above, Deck 2 is not playing so even if you try to use the MIDI command “Set Sync Master”, it doesn’t do anything. With djay, a non-playing Deck cannot be the Sync Master.
If you instead follow this sequence, you should be able to force Deck 2 to become the Sync Master:
- Deck 1 playing with both channel faders up and crossfader in the middle (Deck 1 is the Sync Master by default because it is the first deck playing through the Main Output)
- Load a song on Deck 2
- Press play on Deck 2 (Deck 2 is currently the Sync Slave Deck).
- Use the MIDI mapped command for Deck 2 → “Set Sync Master”.
- Now Deck 2 is the Sync Master.
- Press Sync on Deck 1 and note that Deck 1 BPM changes to match Deck 2 BPM as expected.
a. The easiest way I’ve found to remember this is to always press Sync on the Deck that you want to be the Sync Slave. In other words, press Sync on the side that you want to have the BPM change on. So, if you want the Deck 1 BPM to change and match the Deck 2 BPM, press Sync on Deck 1.
Regarding more decimal places for the BPM, there is an existing suggestion topic for this: Bpm option to have more decimal places
