transport

If you want to synchronize realtime performed events to the Max transport, or to the Live transport in Max for Live, you need to hold onto the vital information about the performed event until the next beat (or downbeat, or whatever your unit of quantization is), then trigger it. For example, in Live, when you trigger a new audio clip, if the launch quantization is set to 1 Bar, your clip will not be launched until the next downbeat. Live holds onto your request to launch the clip, then enacts it when the downbeat of the next bar arrives.
