"wait for note" misses first note?

[eric105]

hello, i am using pro tools to record songs that i have written on a roland mc-909. since everything is already sequenced, i want to record the midi data into pro tools, and then get audio into pro tools by sending each individual midi track to a sound module and capturing the resulting audio. i also want to enter the tempo data into the ruler, and line up my midi data with the bars and beats ruler. it would make sense for me to use "wait for note" and just hit play on my sequencer, but for some reason, when the data is recorded in the edit window, the first note is missed. i feel like i had this working properly in the past, but i am not positive. any ideas on how to make this work?
