2. DynaControl Input Jack
This is the macro dynamics input for the module. We think of this as the ‘how hard the drummer hits’
input. Start here for CV modulation! By default, all parameters that have attenuverters are
normalled to this jack (meaning they call get this signal if their corresponding CV input jacks are left
unplugged). Then you now can ‘program’ the dynamics response using the attenuverters. See the
Musical Dynamics and DynaControl section for more details how to fully exploit this system.
3. TUNE Input Jack
1V/oct control over the VCO base pitch. The VCO in Portal Drum will track many octaves with high
precision so be sure call Portal Drum up for pitched instrumentation too!
4. AMP DECAY CV Input Jack
This input allows for external voltage
control over the AMP DECAY time. It is
summed with the AMP DECAY knob setting.
5. DRIVE CV Input Jack
CV control over the drive of the wave
distortion circuits.
6. SPAN CV Input Jack
CV control over the span of the gap filter.
7. OUT Jack
Final output of the drum.
8. S&H ENABLE Switches
When set to the right, a S&H circuit is
enabled. Nice, eh? The allows drum CV
modulations to be locked in with every HIT
signal. Turn these off if you want to hear
modulation movement between HIT pulses. Special Note: The first two switches do not have
dedicated CV input jacks - the corresponding circuit written in blue under the switches indicate which
circuit to apply S&H. ‘pitch dcy amt’ = PITCH DECAY AMOUNT and ‘trnst amt’ = TRANSIENT AMOUNT.
9. FINE TUNE Knob (Inner)
Base tuning of the oscillator with fine resolution. Offset control.
