Detailed Description

+VstTimeInfo requested via audioMasterGetTime.
See also:
AudioEffectX::getTimeInfo
+
Note:
VstTimeInfo::samplePos :Current Position. It must always be valid, and should not cost a lot to ask for. The sample position is ahead of the time displayed to the user. In sequencer stop mode, its value does not change. A 32 bit integer is too small for sample positions, and it's a double to make it easier to convert between ppq and samples.

+VstTimeInfo::ppqPos : At tempo 120, 1 quarter makes 1/2 second, so 2.0 ppq translates to 48000 samples at 48kHz sample rate. .25 ppq is one sixteenth note then. if you need something like 480ppq, you simply multiply ppq by that scaler.

+VstTimeInfo::barStartPos : Say we're at bars/beats readout 3.3.3. That's 2 bars + 2 q + 2 sixteenth, makes 2 * 4 + 2 + .25 = 10.25 ppq. at tempo 120, that's 10.25 * .5 = 5.125 seconds, times 48000 = 246000 samples (if my calculator servers me well :-).

+VstTimeInfo::samplesToNextClock : MIDI Clock Resolution (24 per Quarter Note), can be negative the distance to the next midi clock (24 ppq, pulses per quarter) in samples. unless samplePos falls precicely on a midi clock, this will either be negative such that the previous MIDI clock is addressed, or positive when referencing the following (future) MIDI clock.
