Summary of Contents for Rabid Elephant Portal Drum
- Page 1 PORTAL DRUM USER’S MANUAL...
- Page 2 ‘how hard’ input as found on a real drum. Portal Drum is capable of a ton of different drum sounds - everything from minimal ‘pillow kicks’ and toms to esoteric perc sounds, rimshots, woodblocks, claves, and ticks n clicks. Just listen and twiddle and you will find your own special spots.

Page 3: Installation
Low loss, high speed active reverse voltage protection, overcurrent protection, ESD protection All Rabid Elephant instruments are professionally hand-crafted products built and designed to exceptionally high standards of performance, quality, and most importantly: musical sound. Click here for more details about this commitment. - Page 4 Interfacing with Portal Drum This is Portal Drum: 1. HIT Input Jack This input is designed such that it will accept nearly any type of signal while still properly hitting the kick drum. The only requirement is that the voltage exceeds +1V. This jack also has a little trick when you leave the DynaControl input unplugged.
- Page 5 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.
- Page 6 Note: the graphic is not representative of the nuances that differ the shapes. The classic shape is *not* linear. The Rabid Elephant shape is novel and has been fine tuned 100s of times over the course of 4 years! It is like an exponential decay but more knee’d. This shape was actually derived...
- Page 7 v1.0.0 16. MEOW Knob Meow uses the pitch decay envelope to set the placement of energy from fully in front to later in the waveform. See the Tips section for more details how this control can be used. 17. DRIVE Knob (Inner) This adjusts the amount of drive into either the portal or saturation circuit.
- Page 8 v1.0.0 25. TRANSIENT AMOUNT Attenuverter 26. HPF TRACK Switch When enabled, the HPF will track 1V/oct of the TUNE input jack post-attenuverter. 27. HPF CUTOFF FREQUENCY Knob 2nd order HPF. The HPF range is to ~1kHz. Offset control. 28. EQUALIZER (Gap Filter) SPAN Knob (Inner) The GAP filter is our answer to mid sculpting.
- Page 9 4. Turn off any S&H switches for parameters you want to hear CV movement between the HIT pulses. 5. Most of the controls on Portal Drum will interact with each other. Try finding a nice transient using the TRANSIENTS TONE and AMOUNT controls (start with DRIVE set pretty low - 25% or so).
- Page 10 Portal Drum did not result in an entirely pristine, clean drum voice. In fact, it did indeed start with ‘hifi’ origins but the drums were missing life. If you need very low noise, try using the Saturation...
- Page 11 Ticks, Clicks, and Transients A key point in the design of Portal Drum was to create a phase correct instrument over the sweeps of all controls. All tonal shaping happens in serial fashion and no additional signals are mixed along in the drum.

If the module calibration is upset we can recalibrate any Rabid Elephant instrument at no cost for the duration of the warranty period (user covers shipping & handling costs). If you feel the instrument needs calibration, email us at: support@rabidelephant.com... - Page 13 Our instruments, we hope, will never end up in a landfill and we design in such a fashion to maximize life. However, we realise everything has a finite lifetime so we would prefer any Rabid Elephant item that would otherwise be disposed be sent back to us. Do NOT dispose of any of our products in the trash! Send it back to us and rest assured it will be disposed of in a safe manner.
- Page 14 v1.0.0 Appendix Quick Terminology Attenuverter: A control that adjusts how much (the gain) of the incoming signal is applied to the target circuit. CW: Clockwise. Turning the knob to the right. CCW: Counter-clockwise. Turning the knob to the left. DC: Direct Current but don’t focus on that. It just means the signal is some constant voltage. Usually DC levels of a signal can be adjusted.
