Short Description
Custom Oneiroi firmware based on Befaco Oneiroi firmware v1.2.2. It changes the looper into an 8th-clock-synced quantized looper with an extended about 8.19-second buffer, selectable 1-4 bar recording, playback-length selection, linear reverse/forward varispeed, and working SOS overdub. 4 bars fit around 120 BPM and faster, 3 bars around 88 BPM and faster, and 2 bars down to about 58 BPM.
!!! Use at your own risk. This is unofficial custom firmware, not an official Befaco release !!!

How To Use
Send an 8th-note clock to SYNC_IN.
Set the looper Length knob before recording. Same zones apply to the playback length knob:
left (CCW): 1 bar
left to 12 o’clock: 2 bars
right to 12 o’clock: 3 bars
right (CW): 4 bars
Press record before the downbeat.
Recording starts on the next clock pulse and stops automatically after the selected length.
After recording, use the Start knob to select playback length: 1, 2, 3, or 4 bars.
Use Varispeed like this:
full CCW: reverse 1x
center: stop
full CW: forward 1x
SOS works:
full CCW: replace recording
full CW: overdub / sound-on-sound
All unchanged Oneiroi functions should work as normal.
What Changed
SYNC_IN expects an 8th-note clock.
Looper recording is quantized to the clock.
Length knob selects recording length before capture.
Start knob selects playback length after capture.
Varispeed is linear from reverse 1x to stop to forward 1x.
Modulation and FX receive a divided 1-bar clock internally.
Looper buffer is extended to about 8.19 seconds.
Limitations / Changed Stock Behavior
Original looper Start and Length behavior is replaced.
Original Length ALT input filter while recording is not supported!
Wavetable behavior may differ from stock because the looper/wavetable shared buffer size changed.
4-bar recording fits only around 120 BPM and faster.
3-bar recording fits around 88 BPM and faster.
2-bar recording fits down to about 58 BPM.
Slower tempos need shorter loop lengths.
This firmware was tested on one module only.
Safety Note
Flash and use at your own risk. This custom firmware worked in testing, but it is unofficial and may contain bugs or behave differently from stock Oneiroi firmware. Keep a copy of the official firmware available in case you want to return to stock.
