16hp digital audio processing unit without fixed structure: intuitively create astonishing and ephemeral timbres: from atmospheric rumbles to heavy or distorted textures creative stereo effect processor with delay, reverb, filter and distortion with quickly explorable routing chain with a single button press matrix of micromodulations creates infinite, alive and unexpected interactions of controls lush hall and whooshing reverse reverbs with audio freeze and predelay sidechain audio ducking with trigger input and one knob single band compressor new generation ARM CortexM7 processor with 96 kHz 32 bit internal processing zerodelay feedback statevariable filters: bipolar lowpass / highpass, band pass and alternative comb filter with resonator tap delay with external clock and clock divider, 1v/oct time control for Karplus Strong, various taps settings with up to 2,5 sec. maximum delay time 8x oversampled distortion algorithm pre and post VCA controls. Tone and Volume controls with extra gain/drive reserve INTRO In collaboration with Andrew Huang, based on his modern music production techniques we developed a creative audio processor with multiple blocks that can be moved around in order to achieve different flavors for sound design. GHOST is a fully digital stereo processing unit without a fixed structure in 16hp: intuitively create astonishing and ephemeral timbres, from atmospheric rumbles to heavily distorted textures. The extremely flexible audio chain consists of a delay, reverb, multimode filter and distortion, where the order of these audio processing blocks can be easily switched with a single press of a button. The ability of the delay to selfoscillate at audio rate frequencies, track 1v/oct signals, be processed by onboard VCAs and an envelope make GHOST a complete KarplusStrong Synthesis voice in itself. ... -
Page 5: Connecting The Power
CONNECTING THE POWER Before installing a new module in your case, ensure your power supply has a free power header and sufficient available capacity to power the module. Connect the module directly to the power busboard with supplied 1016 ribbon cable like any other eurorack module. Pair of RED/BROWN pins on the multicolor ribbon cable corresponds to negative 12V. Make sure to align the power cable with the ‘RED/BROWN STRIPE’ label on the module that corresponds to 12V, to the 10pin connector and with typically a white line for the 16pin connector on the bus board. TECHNICAL SPECIFICATIONS Width: 16 HP/TE, depth: 25 cm / 1” with inserted ribbon cable Current draw: +12V: 130 mA, 12V: 35 mA Audio I/O: 96 kHz 16 bit with 32 bit floating point internal processing CV capture: 16 bit, 2 kHz CV range: 0…+5V typically with up to 0…+10V. 5…+5V for 1v/oct and VCF. Audio input range: typical eurorack standard +/5V (10Vpp) with up to 18Vpp when saturation starts (at around +21 dBu). Audio output: typical +/5V eurorack standard ... -

Page 7: Front Panel Controls
FRONT PANEL CONTROLS IN 1, IN 2 JACKS: stereo audio inputs, INPUT 1 (typically left) – is normalled, i.e. prerouted to INPUT 2 (right) when no audio cable is present • on INPUT 2. Typical input audio level: eurorack modular +/5V with maximum up to +/9V when saturation starts with higher audio amplitude. PREVCA CV INPUT JACK: external 0…+5V CV input that controls the amplitude of the incoming stereo signal. Normalled to +5V when no patch cable is inserted. TONE KNOB: /GAIN* multifunction knob. By default it acts as a 6db/oct TILT EQ for low and high frequencies (CCW and CW respectively) with no effect when the knob is at 12 o’clock. Secondary function is a gain boost for incoming audio, activated by turning while holding the ROUTING button. Fully CCW the signal is at its original level turn CW to boost. DISTORTION KNOB: manual control over the distortion level. Is summed with an external CV applied to the DIST. CV jack. DISTORTION CV JACK: external 0…+5V control over the distortion level. CLIP LED: lights up when clipping occurs at the distortion stage. FREQUENCY KNOB: manual control over the FILTER CUTOFF. VCF CV INPUT JACK: 5V…+5V CV input for the FILTER CUTOFF. ... - Page 8 present at the CLOCK IN jack, the knob acts as a divider / multiplier for this clock with the divisors written around the knob on the panel. TIME CV INPUT JACK: 5…+5V external CV control for the speed of the delay’s repetitions, follows 1v/oct tracking. Is inversely summed with the TIME/DIV knob value when no external CLOCK IN applied: higher CV values shorten the delay time and lower values increase the delay time. When the delay is synchronized to external CLOCK IN, that CV sets the clock divider also summed with the value of TIME/DIV knob. ROUTING /* BUTTON: routing chain switching as well as multifunction shift button. Short presses will cycle through three different orders of audio effects (see FX CHAIN STRUCTURE). Acts as a ‘shift’ button when held down while using other controls (shift functions are labeled with /* on the panel). BUTTON: /TAPS* acts as a tap tempo button for the delay speed. When internal clock is enabled (no patch cable connected) this button blinks fully lit, shown by the symbol under it: . When external clock is patched, the button blinks semilit shown by the symbol under it: . Secondary function (ROUTING + TAPS) changes the stereo behavior of the taps produced by the delay. Available delay tap configurations are: LRLR: left and right summed, taps 1 and 3 hard panned left, taps 2 and 4 hard panned right. LRRL: left and right summed, taps 1 and 4 hard panned left, taps 2 and 3 hard panned right. STEREO: left and right inputs tap independently in their corresponding left and right outputs. In this mode the total delay time is halved. CLOCK IN JACK: 0…+5V external input for the clock that sets the TEMPO of the delay. External clock sets the delay time in sixteenth notes. Module switches to external clock automatically when a patch cable is inserted in the CLOCK IN jack: TAP button blinks semilit following the incoming clock.
- Page 9 TAIL CV INPUT JACK: 0…+5V external CV input for the DECAY of the reverb. HOLD BUTTON: primary function holds or freezes the /REVERSE* reverb, allowing you to ‘hold’ a part of audio until you press this button again. When hold is enabled, this button is fully lit, shown by the symbol under it: . Secondary function in combination with ROUTING /* button switches the algorithm to REVERSE REVERB. When reversed reverb is activated, the button is semilit, shown by the symbol under it: When REVERSE REVERB is activated, a single HOLD button press along with FREEZE trigger input activates and deactivates delay freeze (recirculating delay buffer audio). FREEZE JACK: 0…+5V external trigger input to enable the HOLD of the reverb. Has a latch action: each consequent trigger either enables or disables the freeze. BUTTON: /COMB* switches the filter type from default STATE VARIABLE FILTER LP/HP to BANDPASS filter and back. When bandpass filter is enabled, this button is fully lit shown by the symbol under it: . Secondary function switches to COMB FILTER with resonator by using the ROUTING + BPF button combo. When the COMB FILTER is /COMB* activated, the button is semilit, shown by the symbol under it: . A second press on the button switches back to the LP/HP filter (button unlit). RESONANCE KNOB: manual control over the RESONANCE OF THE FILTER; is summed with the external CV applied to the RESONANCE CV input jack. When the BANDPASS filter is selected, this knob defines the ...

ENVELOPE OUTPUT JACK: 0…+5V envelope output triggered from TRIG IN jack. The envelope has fixed 1 msec attack and a natural sounding exponential curve. While the internal envelope for sidechaining is negative (to duck the audio) this output provides a positive version of the envelope to use elsewhere in your system or modulating module’s parameters. COMPRESSOR KNOB: manual control over the amount of compression applied after the effects processing chain, is summed with an external CV applied to the COMPRESSOR CV IN jack. COMPRESSOR CV IN JACK: 0…+5V external CV input for the compressor amount. VOLUME KNOB: /DRIVE controls the final output volume. Acts as an attenuator for the POST VCA CV jack. When the knob passes after 15 o’clock it adds extra DRIVE saturation to the output signal while trying to maintain its amplitude. POSTVCA CV INPUT JACK: 0…+5V external CV input for the final volume level. Normalled to +5V when no patch cable is inserted. OUT 1, OUT 2 JACKS: final stereo audio outputs. OUTPUT 1 is typically left and OUTPUT 2 is typically right. OUTPUTS 1/2 can drive headphones or be used as separate mono L/R outputs connected with mono cables. When each jack is used with stereo TRS cables, these outputs can be used in PSEUDOBALANCED CONNECTION for example to your audio interface directly. Pseudobalanced connection ensures less noise hum on the long cables but cuts the audio signal amplitude by half – to approximate proline level +/2.5V. Both audio inputs and outputs support airline audio jack adapter (sold separately) to connect a 3.5mm TRS stereo (AUX) cable directly. ... -
Page 11: Distorted Reality
DISTORTED REALITY The power of the GHOST lies in its complex stereo audio effect chain with 96kHz, 32bit internal audio processing, consisting of 2 VCAs (pre and post), 3 distortion stages, a multimode filter, delay, reverb, compressor, and sidechain ducking envelope. The order of the three main processing blocks DELAY/REVERB, VCF, and DISTORTION can be changed by pressing the ROUTING button, letting you achieve many different flavors of sound without having to repatch. The settings of the GAIN, DRIVE and COMPRESSOR in the audio chain are adjusted manually for optimal control over the dynamics. There are three possible orders for the DELAY/REVERB (FX), DISTORTION and VCF blocks: FX DISTORTION VCF DISTORTION VCF FX VCF FX DISTORTION The selected order is shown by the brightness of the ROUTING button, and written as a hint on the faceplate: when ROUTING button LED is off – first chain is selected when ROUTING button is semi lit – second chain is selected when ROUTING button is full on ... -
Page 12: Three Flavors Of Distortion
DIST THREE FLAVORS OF DISTORTION /GAIN: digital input gain (3) capable of light saturation, adjusted with ROUTING + TONE/gain* DISTORTION: 8x oversampled distortion algorithm with a single (8) knob control /DRIVE: final output saturator when VOLUME (34) is pushed to the top of its range, as indicated around the knob on the panel THREE FLAVORS OF FILTER Bipolar LP/HP filter BANDPASS filter (BPF) COMB filter with resonator at high resonance settings. To switch the filter type you simply press the BPF/COMB button. A single press will switch the filter type to a bandpass, and a combination of ROUTING + BPF/COMB buttons will change the filter type to Comb, which is also capable of selfoscillation at full CW or CCW RESONANCE settings. Resonance knob behavior in Comb filter is special: it is bipolar, so from noon it either adds negative (CCW) or positive combs (CW). SPATIAL EFFECTS This chain of audio effects (a.k.a. FX ) consists of a delay which is then routed into the reverb with mid/side widener. DELAY: stereo delay with 1v/oct tracking, capable of KarplusStrong synthesis. The delay can be synchronized externally via CLOCK IN, or by using the ... -
Page 13: Advanced Delay Parameters
MID/SIDE widener stays after the reverb and increases the stereo field simultaneously with the amount of TAIL reverb knob. This feature is best audible on true stereo signals processed with the GHOST. Both delay and reverb have advanced secondary parameters and modes that can be accessed by pressing the ROUTING button in combination with either a knob or another button. These controls are internal and do not have CV control; they are designed as ‘set and forget’ controls to finetune your sound. ADVANCED DELAY PARAMETERS ROUTING + REPEATS KNOB: controls the light TILT EQ that adjusts the TONE / brightness of repetitions: from sparkling clean to dub delays. That TONE* range for repeats is identical to TONE input shaping control. ROUTING + TAP BUTTON: switches the way the delay taps are distributed (hard panned) in the stereo OUTPUTS 1/2. When the TAP button blinks once – the taps appear on OUTPUTS 1 and 2 in an LRLR pattern. When the TAP button blinks twice – the tap pattern is LRRL. When the TAP button blinks 3 times – STEREO mode is selected, where the delay taps appear on either L or R output only when there is something present on L or R input, aka true stereo operation. The true stereo mode shortens the maximum delay time by half. Minimum delay time manually set with TIME/DIV knob corresponds to approximate C4 note (~261 Hz) in LRLR and LRRL taps and approximate C5 note (~523 Hz) and 1 octave more with external 1v/oct TIME CV applied. ... -
Page 14: Dynamics Shaping
REVERSE REVERB is activated (see next), HOLD button activates and deactivates freeze for the delay (recirculating delay buffer audio). ROUTING + HOLD BUTTON: switches the reverb to the REVERSE algorithm, particularly useful for obtaining whooshing sounds by processing kicks, snares, pads, vocals and so on, giving you an extra dimension of movement. DYNAMICS SHAPING In order to tame our signal at the end of the main processing chain we have the following dynamics blocks: COMPRESSOR and SIDECHAIN ducking envelope. COMPRESSOR Oneband peak stereo compressor controlled by a single knob, from none to light to heavy compression settings with predefined and manually tuned values to fit various music styles for best performance. Compressor behavior varies on the audio material and music taste. We recommend setting for 12 o’clock for ambient/pads and full clockwise setting for obtaining snappy drums. SIDECHAIN DUCKING Sidechain ducking ‘compression’: this is the last stage in the audio chain before the final postVCA volume control. The sidechain envelope is triggered using the SIDECHAIN TRIG. INPUT jack. Its release time is set with the SIDECHAIN knob, and its depth of ducking is controlled by holding the ROUTING button while turning the SIDECHAIN knob. RESET In case you have tweaked everything so hard you have distorted signal main outputs, a soft reset adjusts all advanced / secondary parameters to their default values, so you may start tweaking from the beginning. Press all four buttons simultaneously and hold them for more than 3 seconds. Release them once they are all four on, and module will reset to its default values. ... -
Page 15: Patch Examples
PATCH EXAMPLES ROUTING 1 KARPLUS-STRONG SYNTHESIS Ghost can function as a complete KarplusStrong Voice by using the delay at the shortest time setting for sound generation and builtin filter, VCAs and envelope as tonal / dynamics control. Set the ROUTING mode to the first order (FX DISTORTION VCF) when → → ROUTING button LED is off Set REPEATS to maximum with TIME/DIV delay time turned fully CCW. Moderately adjust DELAY DRY/WET to the 12 o’clock Feed any audio to the GHOST audio inputs to start up the KarplusStrong sound generation. You will hear a strong recirculating oscillator sound of approximate C4 note (~261 Hz). Its amplitude is rather high therefore it is convenient to adjust it by DELAY DRY/WET knob Patch a trigger / gate signal from your sequencer to the SIDECHAIN TRIGGER input: this will trigger an internal envelope that will come out from the ENVELOPE OUT. The decay of the envelope is controlled by the SIDECHAIN knob Patch the signal from the ENVELOPE OUT to either: DELAY DRY/WET CV IN or the POSTVCA input to shape our oscillator in different stages Split the ENVELOPE OUT signal and patch it to the VCF CV input for additional tonal shaping ... -
Page 16: Ghost Drone Routing 3
Split your techno 909style kick drum and apply it into AUDIO IN 1 Set the DISTORTION and COMPRESSOR knobs to own taste, usually around 12 o’clock Set the VCF filter type to normal LP/HP and set the filter FREQUENCY knob around 11 o’clock Apply clock from your sequencer into CLOCK IN jack (typically expected in 16 notes) and set the TIME/DIV knob to obtain desired repeats. Set DELAY DRY/WET and REPEATS to own taste, usually both around 12 o’clock Enable REVERSED REVERB by ROUTING + HOLD/reverse*. Set REVERB DRY/WET and TAIL to your own taste until you obtain a whooshing sound. For proper groove set the predelay amount by ROUTING + TAIL/preleday* to approx. 12 o’clock Apply kickdrum trigger into SIDECHAIN TRIG IN jack. Set the ducking envelope amount to 50% with ROUTING + SIDECHAIN to 12 o’clock. Then move SIDECHAIN knob alone to around 1011 o’clock to catch the proper pumping time Mix the sound from AUDIO OUT 1/2 with the original kick drum using a mixer such as Cockpit 2 TIP: it is best to keep your low end consistent or even better MONO. So when using the delay to create the rumble, set TAPS DISTRIBUTION to STEREO mode via ROUTING + TAP to avoid PINGPONG effect or simply only use AUDIO OUT 1. ROUTING 3 GHOST DRONE GHOST structure and multidimensional modulation matrix is capable of producing dark drones and ephemeral soundscapes full of texture and harmony. Set the ROUTING mode to the third order (VCF→FX→DISTORTION) when ROUTING button LED is off when ROUTING button is fully lit . Select the COMB FILTER by pressing the ROUTING + FILTER BUTTON and set the ... -
Page 17: Firmware Update
Set DISTORTION to 20% and COMPRESSOR to 70% to bring in some noise Send a PITCH sequence to the VCF CV input. COMB does not track 1v/oct, but this allows you to highlight frequencies without doubling the amplitude of the fundamental of the sound source. Set the FREQUENCY CUTOFF knob to 11:00 with VCF CV attenuverter fully CW Start the sequencer and listen how GHOST creates timbres on top of a steady oscillator Patch another 1v/oct PITCH CV signal to your oscillator and play around with the notes, you will hear how new ghost harmonies appear, let them direct your next note. FIRMWARE UPDATE Firmware updates are essential for any digital modules. They bring new features or bug fixes. Feel free to write any bugs, features ideas or improvements to beta@endorphin.es To update the firmware on your Ghost, first download the latest firmware file once available on ENDORPHIN.ES website: https://www.endorphin.es/modules/p/ghost The update procedure is done via audio: either computer or phone will work, we advise you to disable all notifications (flight mode) so that the update is not interrupted. 1. Power OFF your modular system. 2. Unplug all the cables from GHOST except a simple mono or stereo cable connecting the audio output from your computer headphones output to the AUDIO IN 1 input of the module. 3. Set the output volume of your computer to 100% or slightly lower. 4. Hold ROUTING while powering your system ON you will see both CLIP and /ENV DEPTH* LEDs on. 5. Open the Ghost_Update_xxx.wav file with any audio player. Press play and wait 1.5+ minutes while the firmware is updating. Both CLIP and /ENV DEPTH* LEDs will slowly blink during that procedure and a row of 4 buttons will show the approximate signal level as imaginary VU meter. Try to adjust the volume of the update so it will not clip but also will be enough level to blink the VU meter. ... -
