6/11/2023 0 Comments Simple delay syncWe can now visualise what’s coming in to the push in by temporarily connecting in the subpatch to an output,, and connecting the second output of subpatch to in the main gendsp patch. The range of the needs to be set to -1 1 in the inspector, accessible via View > Inspector Window, and audio needs to be turned on for it to work. Remember, we use objects to get out of the gen and gendsp parts of the patch. ģ.) We can see what’s going on inside the subject by creating a third output from our gendsp patch with an object called and visualising the output with a in the main maxpat. We then need to connect the subpatch to the push button / trigger input which comes into. If we look inside the subpatch by double-clicking on it, it might look a bit strange even to seasoned Max users, but don’t worry, we’ll be unpicking it to see how it works.Ģ.) Now we need to paste this subpatch back into. If you’re going to reuse a bit of code, you can make it into a subpatch or abstraction. ![]() The object called is a subpatch we’ve made to count the elapsed time between two presses of the trigger on the OWL. We need to copy the object inside the gendsp patch. ![]() Try it out and download the gendsp file here:ġ.) We will begin by grabbing a ready made tap tempo analysis subpatch from the TXdelay patch. This is a delay that can be quantised either by tapping the push button on the OWL or by using an external clock connected to the push input. We will be building on that patch, and if you haven’t done it already, we’d recommend starting with that tutorial which is available here. Just set the B-Chain input mode to “monitor feed” instead of “fixed format” – and you should be able to route your bus out to the B-Chain setup.Today we will be adding a tempo sync or tap tempo function to the simple delay we worked on in the last tutorial. In current versions of Resolve 17, B-Chain now works great in flexbus projects. Hi everyone, just a quick update since this Insight was released. Creating B-Chain monitoring presets for various formats and delaysĪs always – leave me any comments or questions below!.Measuring sync offsets using an iOS app.Setting up a test pattern to measure sync, including patching Fairlight’s builtin oscillator.The B-Chain tools in Fairlight allow you to build custom audio monitoring presets You can use the B-Chain to set up complex monitoring configurations and quickly switch between them. What if a simple delay isn’t enough? What about more complicated surround systems? That’s where Fairlight’s B-Chain tools come in. If you haven’t used macro software before – check out my insights on AutoHotKey for Windows, and Keyboard Maestro for Mac to get up to speed. It gets a bit more complicated with multiple monitors – so I use Keyboard Maestro to automate changing the sync offset. Once you know the offset, it’s as simple as dropping it into your preferences to get your audio and video locked into sync. It makes it easy to line up audio and video test patterns and tells you the exact offset in milliseconds. While there are dedicated hardware devices to measure video/audio sync, inexpensive apps on tablets and smartphones we already all own do just as good a job! Personally, I use the iOS app Catchin Sync. This means it’s important to measure the delay for all your monitors and offset your playback accordingly. Sync is especially hard to get right – as just about every monitor has a different processing delay. ![]() The last thing you want during a grade review is a client asking ‘is this the right mix”’ or is that in sync or is it a bit off?’ Tutorials / Getting Sync’d Up: Advanced Audio Monitoring In DaVinci Resolve Getting Audio Monitoring RightĪudio monitoring isn’t something we think about very often in the grading suite – but when there is a problem, clients can notice.
