[PD] IAC Driver Latency (Samuel Burt)

[Samuel Burt]

Final update for anyone searching the archive:

Screen-capture was causing the delay.

I was revisiting this older patch and realized that I was attempting to
capture the gemwin output with my old computer. That caused the video
rendering to be later than the audio. Specifically, I was using a [gemhead]
to bang [pix_snap] at full resolution.

My solution was to stop using an external MIDI sequencer, instead using
[seq], and then transferring the files to a more powerful Windows 10
computer that has built-in X-box screen capture with Win-G.

In the end there was still latency (about 1600ms) that might be my fault
between creating the audio and MIDI files. So, I just put a little delay on
the audio.
