Public Attributes | |
double | samplePos |
current Position in audio samples (always valid) | |
double | sampleRate |
current Sample Rate in Herz (always valid) | |
double | nanoSeconds |
System Time in nanoseconds (10^-9 second). | |
double | ppqPos |
Musical Position, in Quarter Note (1.0 equals 1 Quarter Note). | |
double | tempo |
current Tempo in BPM (Beats Per Minute) | |
double | barStartPos |
last Bar Start Position, in Quarter Note | |
double | cycleStartPos |
Cycle Start (left locator), in Quarter Note. | |

VstInt32 | timeSigNumerator |
Time Signature Numerator (e.g. 3 for 3/4). | |
VstInt32 | timeSigDenominator |
Time Signature Denominator (e.g. 4 for 3/4). | |
VstInt32 | smpteOffset |
SMPTE offset (in SMPTE subframes (bits; 1/80 of a frame)). The current SMPTE position can be calculated using samplePos, sampleRate, and smpteFrameRate. | |
VstInt32 | smpteFrameRate |
VstInt32 | samplesToNextClock |
MIDI Clock Resolution (24 Per Quarter Note), can be negative (nearest clock). | |

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.
