The Global tempo in the G-Force makes it possible to change several Speed parameters at once. It can be used with Delay time, Panner/Tremolo, Chorus/Flanger, Phaser or LFO speed. It can not be used with Pitch Shift delay time, Reverb pre-delay/decay times or ADSRs.
To use the Global tempo, select Tempo > Override preset tempo at preset change, choose a Tempo note subdivision in an effect menu and finally select or tap in a tempo in the Global tempo menu.
Since the G-Force's Global tempo can't be synced to MIDI clock (when hooked up with other MIDI gear such as sequencers or drum machines) you must either set it manually on all machines, tap it in with the G-Force front panel button (difficult) or tap it from an external MIDI device such as a MIDI board footswitch. When tapping in a tempo only the last two taps are counted (other effect processors such as the Lexicon MPX-G2 are said to calculate the average value from a number of taps as their tap tempo, which sounds like a better solution to me).
This global parameter decides wether the tempo should override Speed or Delay time values or not. When set to Yes, effects follow the Global tempo if you have chosen a Tempo note subdivision in the effect, otherwise the fixed parameter values are used and the Global tempo is ignored.
When set to No, effects in presets will use their fixed Delay time or Speed values (even if you have set a Tempo note subdivision) until you tap in a new tempo, which then overrides the fixed values. You must tap in a new tempo at each preset change, unless you want to use the fixed values. Once you have tapped in a new tempo you cannot go back to the fixed values until you change preset again.
The No value might be useful if you set a fixed Speed value in an effect to Off. Whenever you recall that preset, the Speed parameter will stay turned off until you tap in a new tempo. For example, if you set Delay time to 0ms in a preset there will be no delays until you tap in a tempo, or if you set Tremolo speed to off in a preset, there will be no tremolo until you tap in a tempo.
Below you can calculate different time values. Use periods for decimal numbers, not commas ("0.5" and not "0,5"). There's a more advanced tempo calculator at www.tubefreak.com.
BPM means beats per minute, Hz (Herz) means cycles per second, ms (milliseconds) means thousands of a second:
The higher the tempo (in BPM) and the smaller the note sub-divisions, the shorter the delay time:
The G-Force Tempo menu can be used as a simple calculator for BPM to ms conversions (using only 1/4 note subdivisions). You can also use the Tempo parameter in the G-Force Delay for BPM to ms calculations, where the selected Tempo note subdivision together with the Global tempo is shown as a millisecond value.
Note that the G-Force Delay Tempo parameter can display higher ms values than the Delay is able to produce. For example, if the Global Tempo is 120 BPM and the delay Tempo subdivision is set to 1/1 it will display the theoretically correct delay time value 2000ms, which is longer than the max G-Force delay time. This can be confusing unless you know the max delay time of each Delay sub-algorithm. This is not a bug, according to TC Electronic, but a deliberate design solution.
