ER-101 under remote editing control. The ER-102 was designed to be place to the right of the ER-101. This layout was chosen to minimize the impact on your hand motions when including the ER-102 in your workflow. -

MATH button. A non-destructive transform alters step parameters as they are being interpreted during playback but without changing their stored values. You will find non-destructive transforms in the GROUP MODIFIER section of the ER-102’s interface. All transforms share the following interface: UI Element... -

Operations Code Operation Range Effect Addition -99 to 99 add A Whenever you apply a transform, all of the operations that it contains are applied Multiplication 1/99 to 99 multipy by G sequentially in the following order to each step parameter: Jitter 0 to 99 add a random integer between [-Jt, Jt]... -
Page 6: Examples
Examples Set parameters to a specific value: To achieve the affect of an assignment operation, just set G = 0 and set A to the desired value. Typically you would do this when you want to simultaneously set a particular parameter of many steps to a desired value (e.g. set the DURATION of all steps in a pattern to 16 clock pulses). -
Page 7: What Are Parts
What are parts? The top section of the ER-102 is dedicated to the manipulation of parts. Using parts, you can divide tracks into smaller sub-sequences (called parts) and then activate these parts during playback using the manual interface or using voltage control. A single snapshot can contain up to 99 parts. -
Page 8: Interface
The looped section of the focused part is set with the LOOP START and LOOP END buttons on the ER-101, while the reset step is assigned with the RESET TO button on the ER-102. Pending Part The pending part is the part that is scheduled to play next (i.e. -
Page 9: Voltage Control
= floor(voltage*10) Parts can be focused and activated using external voltage control just by patching a suitable CV/gate source into the SELECT and ACTIVATE jacks on the ER-102. The maximum:99 SELECT voltage is converted to a PART number according to the chart on the right. -
Page 10: Various Types Of Parts
Various types of parts There is no restriction on how you assign the RESET TO, LOOP START and LOOP END steps in a part. In the following, I will borrow terminology used to describe the structure of popular songs because it is familiar and easy to understand. Suppose the material for a song was laid out over a track or tracks in the following manner: Intro-Verse-Chorus-Bridge-Outro Material that is laid out this way is not meant to be played from start to finish but to... -
Page 11: Transitions
Transitions Once a part is triggered, the exact time it will start playing depends on the setting of the TRANSITION switch. Triggering a part Parts are activated or triggered in two ways - manually via the TRANSITION button or remotely via a rising edge on the ACTIVATE input. As soon as the focused part is activated then it also becomes the pending part and its number will be flashing in the INDEX display when the PART display is also focused. -
Page 12: G Roups
What are groups? The middle section of the ER-102 is dedicated to groups. Groups are arbitrary selec- tions of steps that can be the target of transforms and CV/gate modulation. Each snapshot can contain up to 16 groups. There are 3 independent channels of CV/ gate moduation. -
Page 13: Applying Transforms
Copy a selection If you press the COPY button while the GROUP display is focused then the current group’s selection (but not the steps themselves) is copied to the clipboard. At this point the GROUP display LED will start flashing. You can now navigate to another group and paste the copied selection with the INSERT button. -
Page 14: Modifiers
Modifiers CV-A 0.05 The modifiers of a group dictate how the 3 channels of CV/gate modulation (X, Y, CV-B 0.25 and Z) affect the steps within the group. The SLOPE modifier holds the gain matrix DURATION that routes the 3 CV inputs to each parameter of each step in a group. The HIGH and GATE -4.0 LOW modifiers are non-destructive transforms which are activated according to the... - Page 15 When altering the slope, the size of the encoder increments depends on the slope’s magnitude: Increment -9.9 -1.0 -0.99 0.99 0.01 This logarithmic scheme allows for fine control when dialing in small gains while also making very large gains easy to reach. High vs Low transforms The GATE inputs on the 3 modulation channels (X, Y, and Z) control which of each group’s (non-destructive) transforms are active.

Page 16: Ecording
The lower section of the ER-102 is dedicated to recording and remote control of the ER-102 editing functions. In addition to the PUNCH IN/OUT gate input, there are 6 multi-purpose inputs: A-1 and A-2: analog inputs that accept -10V to 10V D-1 and D-2: digital inputs with a trigger threshold of 1.5V. -
Page 17: Real-Time Mode
The CV index that is assigned to the current recording step is determined in the following manner. Once a new step has started, the ER-102 then waits for approx- imately half a clock pulse before sampling the A-1 and/or A-2 inputs. This helps insure that the voltage on these inputs has settled to an accurate value. - Page 18 CV/Gate trigger vs Gate-only trigger A configuration screen is shown whenever you arm a track for real-time recording. This screen has the following options: Display Purpose Range Default CV-A Trigger a new step when CV-A changes? tr, -- CV-B Trigger a new step when CV-B changes? tr, -- DURATION Quantization grid for step durations.

Page 19: Step Mode
Step mode The purpose of step recording is to use an external CV/gate source (such as a CV/ gate keyboard) to insert and delete steps but ignore the timing with which you do it. The STEP record mode essentially places the ER-101 under remote editing control. Unlike the other two recording modes, this mode inserts/deletes steps at the edit cursor, not the play cursor. -
Page 20: Alter Mode
Alter mode This mode is similar to the REAL-TIME mode in that steps under the play cursor are affected and recording happens in real-time. However, no new steps are inserted in the armed tracks. Instead, step parameters are overwritten with new values that are derived from the input voltages. -
Page 21: R Otoinversion
otoInversIon The ER-101 provides the COPY operation and the MATH transforms as its main tools for generating new material from existing material. However, permutations of a given sequence were not easily accessible except via manual step-by-step editing. Hence, I included the inversion and rotation operations (i.e. rotoinversion) on the ER- 102. -
Page 22: S Torage
(see the section on Configuration Files). Lastly, the METAINFO.BIN file is used by the ER-102 to keep track of some internal state like the last snapshot loaded and what version of the ER-102 firmware last accessed this SD card. -
Page 23: Snapshots
Prepare and save template snapshots for quick startup later on. After you save a snapshot (such as to the A1 slot in this example) then the file struc- ture will look like this: ER-102/ SNAPSHOT/ LATEST.BIN R0001.BIN R0002.BIN... -
Page 24: Loading Midi Files
Loading MIDI Files The ER-102 can load SMF0 (single track) and SMF1 (multiple track) type MIDI files but not SMF2 (song files). The procedure for loading a MIDI file is simple. Think of it as manually initializing a snapshot slot with a MIDI file that you provide: On your computer, Choose a snapshot slot (such as C4). -
Page 25: User Voltage Tables
User Voltage Tables When using the ER-102 with your ER-101, the user reference voltage tables are saved to and loaded from the SD card: ER-102/ TABLES/ JUI7.BIN USR1.BIN USR2.BIN USR3.BIN USR4.BIN USR5.BIN USR6.BIN USR7.BIN USR8.BIN The USR(1-8).BIN files contain the 8 original user voltage tables from the ER-101 and are initialized with the 12ET chromatic table. -
Page 26: The Configuration File
If it doesn’t exist, then let me know and I will see what I can do. The configuration file (aka CONFIG.INI) lives in the ER-102 directory of your SD card. The configuration file is re-read by the ER-102 whenever you: •... -
Page 27: Updating The Firmware
To update the firmware on the ER-102, download the newest firmware binary from: http://www.orthogonaldevices.com/er-102 and copy the file (e.g. f1_02.bin) to the FIRMWARE directory on your microSD card. Do not rename the file. The ER-102 requires the firmware files to be named in a specific format: f<major version>_<minor version>.bin Next, place the microSD card back into the ER-102’s card slot and switch the STOR-...
