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. <p>
<a class="el" href="struct_vst_time_info.html#a243da6be1161a971983e68be39e7a28">VstTimeInfo::ppqPos</a> : 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. <p>
<a class="el" href="struct_vst_time_info.html#52d38a95a4c34ea3fb060388d4b412d2">VstTimeInfo::barStartPos</a> : 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 :-). <p>
<a class="el" href="struct_vst_time_info.html#a64d2f92ed1a617aae11b3c785073ad7">VstTimeInfo::samplesToNextClock</a> : 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. </dd></dl>
