Page 3: Intro
Oneiroi is an experimental synthesizer designed for creating ambient pads and drone-like soundscapes. It has a full stereo signal path, 3 oscillators (2 of which are mutually exclusive), 4 effects, and a looper. It also includes self-modulation and a randomizer. Oneiroi is built on Rebel Technology’s OWL platform. - Page 4 ● CV controls for all the primary parameters, four of them can be dynamically assigned to the secondary ones as well ● Record either the stereo input or the module's output ● Various types of self-modulation with configurable routing and control over level and speed ●...

Page 8: Shift Button
Additionally, this button is used for saving the current state of the module. (see next chapter) 8 Manual Saving When using Oneiroi, there are instances where the position of the manual controls does not match the actual parameter value. In these cases, it is important to perform the SAVE operation to ensure that all parameters maintain their state after power cycling. -
Page 9: Synchronization
9 Synchronization The SYNC IN input allows for synchronizing Oneiroi with an external source. The module needs a couple of seconds to align to the external sync and at the same time to go back to internal sync when the external is removed. - Page 10 10.2 Looper This unit can be used for recording and playing back approximately five seconds of either the audio coming from the stereo input (PRE) or the audio sent to the module’s output (POST), depending on the position of the PRE/POST switch. The bi-color LED monitors the signal level coming from the stereo input when the PRE/POST switch is set to PRE or the level of the signal sent to the output when set to POST.

progressively slower and at 100% it never fades away. During recording, the SOS is processed through a DJ-style filter whose response can be changed by holding the SHIFT button and turning the LENGTH knob: at noon no filter is applied, going clockwise an HPF is applied, going counter-clockwise an LPF is applied. -
Page 12: Resonator
The filter can be placed at one of the four possible positions in the effects chain by holding the SHIFT button and turning the RESO knob: I- At the beginning of the chain II- Between the resonator and the echo III- Between the echo and the ambience unit IV- At the end of the chain 11.2 Resonator... -
Page 13: Modulation
frequency’s division/multiplication at the same time: At 0% no auto-pan, at 100% full auto-pan at 8x the base frequency, in between there are 16 different ratios (default is 50%). 12 Modulation This unit provides several types of modulation sources that can be mapped to all the parameters with knobs (except the ones on the modulation itself). -
Page 14: Randomizer
This modulation mapping can be erased while in modulation mapping mode by pressing both the RECORD and RANDOM buttons at the same time. Be advised that all changes made must be manually saved to persist after a power cycle. (See Chapter 4.3) 13 Randomizer The Randomizer allows you to create instant soundscapes by changing the parameters of one... -
Page 15: Voltage Control
4.3) 14 Voltage Control Each Oneiroi knob (except the modulation knobs) has a dedicated control to set the amount of CV it receives. To access the controls, enter the CV mapping mode by pressing the SHIFT and the CV AMT buttons together. Then, adjust the knob you want to be affected by the CV from 0% to 100% (the default is 100% for all primary parameters). -

4. Connect Oneiroi to your computer using any of the USBs on the back side. On your browser, go to the OpenWare Laboratory: https://pingdynasty.github.io/OwlWebControl/extended.html 5. Check if Oneiroi is connected to the page: The page should say: "Connected to Oneiroi vx.x.x" 6. Click "Choose file" and upload the patch.syx from your computer 7. - Page 19 Only needed after the module's assembly (usually only at the factory or by DIYers) or after some critical components have been replaced. The more precise is your voltage source the more precise the calibration will be. A +/-0.005V tolerance voltage source is recommended for this operation. A wrong calibration will disrupt the module's functionality.
