EPHEMERE
USER MANUAL

INSTALLATION:
This is a high-resolution dual-channel recording interface for your signals
mainly focused on recording control voltages.
You can record from 1014 sec at 172Hz up to 4 sec at 44.1kHz of signal
on each channel, change the playback speed and scan through the
recorded CV.
There is a dedicated attenuverter pot for your incoming signals. When
nothing is patched to the input you can use the input pot as an offset/cv
generator and record pot movements into the module.
It´s possible to save, load your signals and settings on the SD card up to
16GB of space
There are 4 different recording modes to choose from to make more
complex signals to prepare your live performances.
INTRODUCTION:
* Disconnect your synth from the power source
* Double check polarity from the ribbon cable
* After connecting the module check again you have connected the right
way, the red line should be on the -12V
* BE CAREFUL THE PINS FROM THE BACK OF THE PCB SHOULD
NOT TOUCH ANYTHING WHILE IS POWERED
BEWARE IF YOU DON´T FOLLOW THE STEPS DESCRIBED ABOVE

Menu diving has been changed for a better experience. Practical way to
choose from different ways of recording, playing signals.
There are 2 rules to follow so everything will be easier when you start to
dive into the module architecture settings.
Rule 1 “Select button go inside the menu then select the setting”
Rule 2 “ Pressing encoder exits the menu, also in the app it
changes the OLED display from showing the recorded signal to show
the live ADC signal”
To access the main menu hold press select button for 1 sec,
rotate the encoder to scroll through the menus, press select to enter.
To exit the menu simply press encoder.
There is a new menu called “show in menu” by choosing a menu from the
list, you will enable 1 specific menu for quick access in the app by pressing
select button, this way you can have the most useful setting chosen for the
signal you are working on at that moment.
Every signal saved in the SD card will also keep the settings chosen for
that specific signal
1. PLAY MODE:
a) Loop: The playback of the signal will play in loop until STOP is pressed.
b) One shot: The playback of the signal will stop when it reaches the end
or if STOP is pressed.
Hold pressing PLAY button for 2 sec, triggers to Play are ignored LED
will blink, this is useful for REC Sync mult-G, repeat to disable.
2. PLAY DIRECTION
a) Forward
b) Backward
c) Pendulum
3. SPEED MODE:
a) Quantized: Playback stepped speed from /5, /4, /3, /2, x1, x2, x3 ,x4, x5.
b) Lineal: Playback speed from /5 to x5
4. REC MODE :
a) Manual: Pressing REC will start recording, pressing REC again will finish
recording.
b) Manual mult: Pressing REC will start recording, pressing REC again will
finish recording.
(If PLAY is pressed during recording, or trigger is received to PLAY input
recording proccess will be paused, pressing PLAY again or receiving a
trigger to PLAY input jack will continue recording)
c) Sync: Pressing REC will wait for a trigger from REC trigger input to start
recording, when a second trigger is received to REC input again will finish
recording

d) Sync mult: Pressing REC will wait for a trigger from REC trigger input to
start recording, when a second trigger is received to REC input again will
finish recording (If PLAY is pressed during recording, or trigger is received
to PLAY input recording proccess will be paused, pressing PLAY again or
receiving a trigger to PLAY input jack will continue recording)
e) Manual mult-G: Pressing REC will start recording, pressing PLAY will
pause recording setting the end of grid, pressing REC finish recording
f) Sync mult-G:Pressing REC will wait for a trigger from REC trigger input to
start recording, when a second trigger is received to REC input again will
finish recording (while is recording if trigers to PLAY are received will set the
grids in the recording process)
5. QUANTIZER: Enabling Live CV input/ Recorded CV quantized 1V/oct
6. SCALES: Keyboard menu to enable/disable notes
7.SAMPLING RATE: Select between different sample rate modes
and time length of recording
8. CV Range: Change the offset of the incoming signal from -5/+5V or 0/10V,
it can also change the offset of the playback signal.
9. FILE:
File Load: Loads signals saved on the SD card
File Erase: Erases signals saved on the SD card
File Save: Saves and names signals on the SD card
10. SHOW IN MENU: By choosing a menu from the list, you will enable 1
specific menu for quick access in the app by pressing select button,
this way you can have the most useful setting chosen for the signal you
are working on at that moment.
11. CALIBRATION: Enter to calibrating ADC/DAC menu

c) Menu 2V, send C2 from your sequencer, rotate the encoder while
monitoring your DAW to reach C2
d) Repeat the same process except 10V, because DAW can´t reach
C10 you will need to match ADC and DAC values.
e) Save calibration, exit by pressing encoder, reboot the module
f) Check if calibration is ok, make sure CV range is set to 0-10V and
quantizer is enabled.
CALIBRATION:
·Before you start calibration:
Connect the CV out from your sequencer to Ephemere input, the
output from Ephemere to your VCO, VCO out to your DAW, in your
DAW open tuner VST to monitore notes. Ephemere input pot´s at MAX.
a) Go inside the calibration menu, start calibration proccess.
b) Menu 0.0V, send C0 from your sequencuer, DAW can´t reach C0
you simly rotate encoder to match the DAC value with ADC value.
Press 1 time only to go to the next step.
c) Menu 1V, send C1 from your sequencer, rotate the encoder while
monitoring your DAW to reach C1
Pressing SELECT button one time will register the value, will jump to
the next voltage setup. Make sure not to press until you send desired
voltage to register, don´t press 2 times otherwise you will need to start
again.
