Pitch
Volts per Octave is a common
approach to controlling pitch of an
analog device, especially in Eurorack.
Occasionally this may also follow an
alternative Hz / Volt format, used by
Korg and Yamaha.
Range
Control Voltages can also modulate
various parameters. These may be %
ranges, absolute values, offsets etc. T-
1 has a configuration option for
velocity. While this is based on the
velocity of notes it can be used to
modulate any analog parameter.
Trig
A trigger is a short voltage pulse that
activates an event. A gate is similar but
usually a longer, controlled length. A
trigger is often used for note on, off
and switch functions. V-Trig is the most
common, 0-5 rise to trigger. S-Trig
activates on a falling 5-0 voltage level.
Clock
An analog clock operates on a series
of pulses to synchronise devices.
Pulses are normally measured Pulses
per Quarter Note - PPQN. T-1 has
adjustable settings for analog clock
rates and pulse width to help match up
to devices. Analog clock is the highest
order in the clock hierarchy.
