# Erogenous Tones — Radar - [Manual PDF](../../manuals/radar-instructions.pdf) --- [Manual PDF](http://erogenous-tones.com) # Erogenous Tones RADAR — Cheat Sheet ## What it is **RADAR** is an **8-channel AD/AR/repeating envelope generator**. “RADAR” = **Repeating, AD, or AR**. It has **3 system modes**: - **Envelope Mode**: 8 independent envelopes - **Quad Mode**: two 4-phase groups, or one 4-phase group + 4 independent envelopes - **Oct Mode**: one 8-phase group --- ## Quick Start ### 1) Pick a system mode Use the **SYSTEM MODE** switch: - **Envelope** - **Quad** - **Oct** ### 2) Per-lane basic behavior Each lane can be set to: - **R** = Repeating / LFO - **AD** = Attack-Decay - **AR** = Attack-Release ### 3) Trigger it In **Envelope Mode**, each lane has a **trigger input**. Trigger inputs are **normalized downward** to the next lane. ### 4) Set timing and shape For each lane, adjust: - **Attack** - **Release** - **Shape**: **LOG ↔ LIN ↔ EXP** ### 5) Watch the LED - **Blue** = rising - **Purple** = hold in AR mode - **Red** = falling --- ## Modes ## Envelope Mode Use when you want **8 independent envelope channels**. ### Triggering - Each lane has its own **trigger input** - Trigger is **normalized to the next channel below** ### AD vs AR - **AD**: on rising gate/trigger, runs full **Attack**, then full **Release** - **AR**: - In **analog modeling mode**, envelope rises only as long as gate stays high - If gate is short, it may never reach full level before releasing - In **digital mode**, short gate/trigger behaves more like **AD** ### Gate behavior If gate stays high longer than attack time: - envelope rises - stays high - releases when gate goes low ### Repeating mode Acts like an **LFO**. - In **digital mode**, retrigger resets waveform to zero - In **analog mode**, reset only happens if lane is in release; restart begins from current level/release point --- ## Modeling modes Lanes are controlled in **pairs of 2** for modeling mode and envelope shape mode. ### Digital - Retrigger **resets envelope to zero** from anywhere in cycle - Creates classic digital discontinuities/snaps - Repeating/LFO frequency is **constant** ### Analog modeling - Does **not** reset unless in decay/release - Attack starts from current level - Behaves more like capacitor charging/discharging --- ## Shape behavior ### Shape knob / CV Continuously morphs: - **LOG** - **LIN** - **EXP** - and everything between ### E/O switch Controls whether decay/release shape is: - **E** = Equal to attack shape - **O** = Opposite of attack shape Example: - LOG rise + **O** = EXP fall If attack is linear, both sides remain linear. --- ## Composite outputs Only in **Envelope Mode**: ### Lane 4 output switch Can change lane 4 output to a **composite max output** of: - **Lane 3 and Lane 4** ### Lane 8 output switch Can change lane 8 output to a **composite max output** of: - **Lane 6, 7, and 8** Notes: - In composite mode, the LED is always **purple** - This is a **max-value** combination, not a sum --- ## Quad Mode Lets you use: - **2 quad envelopes**, or - **1 quad envelope + 4 normal envelope lanes** Use the **lane 4 output switch** to choose the behavior for lanes **1–4**. Composite/max output modes do **not** exist in Quad Mode. ### Quad behavior For each 4-lane group: - lanes are **90° apart** - **lane 1** and **lane 5** set rise/fall time for their whole group - **E/O** also comes from lane 1 / lane 5 - works in **digital mode only** - reset on first lane resets all lanes and restores phase relationships ### Extra CV functions in Quad Mode The **2nd, 3rd, and 4th lanes** of each quad group can take on special CV roles: - **SPEED** - **GRAVITY** - **SDELTA** Their switch behavior: - **R position** = CV off - **AD/AR** = off/on respectively via switch or AD/AR input level #### SPEED Modulates overall rate of all 4 channels together. #### GRAVITY Warps timing relationship of 90°/180°/270° lanes relative to the 0° lane. #### SDELTA Offsets/interpolates shape differences from first lane to last lane. Caution: steep modulation can cause jumps because shape curves differ by time/value. --- ## Oct Mode Same concept as Quad Mode, but: - all **8 lanes** - each lane is **45° apart** --- ## LFO / Repeating speed notes Fastest frequencies mentioned in manual: ### Analog mode At fastest settings: - around **1.18 kHz** with **EXP** shape - around **610 Hz** with **LIN** - around **1.18 kHz** with **LOG** ### Digital mode - max about **591 Hz** --- # Controls Reference ## Global controls ### SYSTEM MODE switch Selects: - **Envelope** - **Quad** - **Oct** --- ## Per-lane controls Each lane has: ### RADAR mode switch Selects: - **R** = repeating/LFO - **AD** - **AR** ### Attack control Sets rise time. ### Release control Sets fall time. ### Shape control Morphs: - LOG ↔ LIN ↔ EXP ### Shape CV input Offsets shape knob setting. ### Trigger/Gate input Used to start or control envelopes. ### Output jack Envelope or repeating waveform output. ### LED Shows stage: - Blue = rise - Purple = hold / composite indication - Red = fall --- ## Shared / grouped controls ### Modeling mode switch Per pair of lanes: - **Digital** - **Analog modeling** ### E/O switch Per pair of lanes: - **Equal** - **Opposite** ### Lane 4 output switch - Envelope Mode: normal output or max(lane 3, lane 4) - Quad Mode: selects quad configuration for lanes 1–4 ### Lane 8 output switch - Envelope Mode: normal output or max(lane 6, lane 7, lane 8) --- # Jack Reference > Note: The provided manual pages do **not specify exact voltage ranges** for most inputs/outputs. Where range is not explicitly stated, it is marked **Not specified in provided manual**. ## Inputs ### Per-lane Trigger/Gate inputs - **Function**: trigger envelope, gate AR behavior, reset repeating waveform - **Normalization**: each trigger input is normalized to the lane below - **Voltage range**: **Not specified in provided manual** ### Per-lane Shape CV inputs - **Function**: offsets shape knob position - **Tip**: use an external attenuator to limit modulation amount - **Voltage range**: **Not specified in provided manual** ### AD/AR input - **Function**: can select/activate AD vs AR based on input level in relevant modes - **Voltage range**: **Not specified in provided manual** ## Outputs ### Per-lane envelope outputs - **Function**: envelope or repeating/LFO waveform output - **Voltage range**: **Not specified in provided manual** ### Composite outputs Available only when lane output switch is set appropriately: - **Lane 4 output** = max of lanes 3 and 4 - **Lane 8 output** = max of lanes 6, 7, and 8 - **Voltage range**: **Not specified in provided manual** --- # Practical Patch Tips ## Classic 8-envelope patch - Set **System Mode = Envelope** - Put each lane in **AD** or **AR** - Feed separate triggers to each lane - Use different shape settings for percussion vs slow modulation ## Cascaded triggers Because triggers normalize downward: - patch a trigger into an upper lane - leave lower inputs unpatched - get repeated use of same trigger source across lanes ## Organic envelopes - Use **Analog modeling** - Use **AR** - Send variable gate lengths - Great for plucks, struck tones, and less “snappy” modulation ## Clocked LFO bank - Set some lanes to **R** - Use **digital mode** for stable repeating rate - retrigger/reset from a clock or pulse source ## Composite modulation In Envelope Mode: - switch **lane 4** or **lane 8** to composite output - use resulting “max” contour as a more complex envelope ## Quadrature modulation In **Quad Mode**: - use the 4 outputs as phased modulation - ideal for panning, scanning, vector movement, filter banks, and animation ## 8-phase modulation In **Oct Mode**: - use all 8 outputs as a rotating modulation set - good for sequenced spatial movement or distributed CV animation --- # Gotchas - **Shape CV is an offset**, not absolute control - Use an **external attenuator** for shape CV - **Digital mode** hard-resets envelopes to zero - **Analog mode** preserves continuity unless in release - **Composite output modes** exist only in **Envelope Mode** - **Quad/Oct** are **digital only** - In **Quad/Oct**, only the lead lane of the group controls shared timing/shape behavior --- # Missing from provided manual pages The provided 2-page excerpt does **not explicitly list**: - exact **input voltage ranges** - exact **output voltage ranges** - exact trigger/gate threshold voltages - exact attack/release time ranges - full front-panel jack-by-jack labeling If you want, I can also turn this into a **one-page performance-oriented quick reference** or a **full panel control map** based on the module photo.
