I’m trying to sync the start and stop of Ableton to the Impromptu Clock… I’m using VCV as a VST isndie Ableton, and the Midi>CV module. on that module there is a start jack and a stop jack… ‘Clocked’ only has a Run and no Stop and the Midi>CV Start jack doesn’t seem to output anything…
I’m a bit confused of how to sync the transport… any help appreciated, I’ve looked at everyones YT videos but none seems to say about transport, only bpm sync…
For the BPM sync, you will need to set it to “P24” using the Mode buttons on Clocked. For the start-stop, I think there are some solutions on this forum, but you will have to search for them as I don’t have a link handy.
Haven’t used Ableton yet, but this what I do in Reaper. Manually set the BPM in Clocked to the same as your project, then use a Multiple to patch both start and stop into the run input. Start is also patched to reset:
Sorry but that is not the right way to do it. Trying to match BPMs manually will inevitably result in drift over time. Only mentioning this as other people might come across this thread.
The OP had it right by connecting the CLK output from Midi > CV into Clocked’s BPM input and setting Clocked to P24 mode. That will result in proper sync.
It’s not even necessary to connect the Run and Reset inputs on Clocked as it will run and stop automatically as it detects an incoming clock pulse into its BPM input. You can use the auto reset options in Clocked’s right click menu to deal with the reset.
If you do connect Run and Reset, it’s generally better to use the ‘CONT’ output from Midi > CV than the ‘STRT’ output. ‘STRT’ will only fire a trigger when you play from the beginning of the timeline in your DAW. ‘CONT’ will fire a trigger whenever your DAW starts playing, regardless of timeline position.
I imagine a lot of people who use the ‘STRT’ output think their DAW is sending a trigger when it starts playing from anywhere on the timeline but actually it is just working because Clocked detects the incoming clock pulse and starts auto running and you’d get exactly the same result if you disconnected the STRT cable.
Strange, I couldn’t get that working before but just tried again and the BPM input does indeed start and stop automatically like you say. Cheers! To be honest I’ve not had any problems with the sync drifting, it always sounded pretty tight with the BPM set manually, but it’s good to know how to do it properly.
One thing I’ll add here, again for anyone who comes across this thread later - the next release of Impromptu which should hit the library soon will have a new feature where P24 will be selected automatically if Clocked is in the default BPM CV mode and it detects a clock pulse at the BPM input.
This will remove the need for the user to manually select P24 mode when syncing to the DAW - they’ll just need to connect the CLK out from the Midi > CV module to the BPM input of Clocked and then it should ‘just work’.
