Note that there are no attenuator knobs to set the amount of modulation for the ADBDR envelope CV inputs allowing for direct connection to velocity CV or CC#. However when modulated from other sources they might need extra CV processing to set the modulation levels properly.<ref name="rh" />
 
=== Gate or Trig Toggle ===
New versions of the module feature a toggle switch to select between GATE or TRIG modes. When using long pulses or 'gates' as inputs the envelope will pause at the break level while the gate is high, and continue when the gate is low. Toggle mode will simply run through all stages of the function without interruption. <!-- Need to clarify this with testing or Rob. -->

=== Sample & Hold ===
When modulating decay times with control voltages it is good advise to keep the voltage fixed while the envelope is developing. For example trying to modulate the decay time with an audio rate signal does in general not produce sensible results. A S&H is integrated into the module to sample the decay time modulation input signal for the second envelope(S&H generatorIN) on every new gate trigger. This way the modulation amount will stay fixed until the module is triggered again by a new gate pulse. The full sampled signal is alsosent broughtstraight outto onthe aS&H connectorOUT, so it can be routed to a CVan input of choice on ENV A or use elsewhere, but is attenuated using the firstENV ADBDRB envelopeMOD generator.knob Orbefore bebeing usedsent into anythe otherENV S&HB DECAY applicationfunction.<ref name="rh" />
