SoundForce uDCO

Features:
The SoundForce uDCO features 8 rotary pots. 5 sound sources are available: SAW, PULSE, SUB1 (1 octave lower), SUB2 (2 octaves lower) and NOISE. The built-in mixer allows you to mix them together using the pots and the MIX output jack. The PWM pot is acting either as manual PWM control when nothing is plugged into the PWM CV input or as attenuator for the PWM CV when a cable is connected. An FM input is also available without attenuation. The oscillator can be hard synced to another oscillator using the SYNC input. The SYNC input jack is shared with the MIDI interface GATE output. A little switch at the back let you choose between the two.

MIDI interface:
The new MIDI input allows you to connect the uDCO directly to your computer’s MIDI interface or any hardware with a MIDI output (no USB-MIDI). For totally flawless MIDI tuning, a switch at the back allows you to deactivate the Coarse/Fine tuning sliders and VOCT CV input. In that mode, the FM input and FM attenuator are functional and you can still affect the MIDI tuning if you’d like to. The other mode is combining the incoming MIDI notes (if you are sending some), the CV inputs and the Coarse/Fine sliders to generate the uDCO’s frequency.

Switching MIDI channel:
The inside 2 little tactile switches on the lower PCB allows you to set the MIDI channel. Per default, the setting is set to OMNI and all channels are processed. With the inside right switch (label at the back is UP), you can increase the channel by 1 at each press of the switch. With the inside left switch (label at the back is DOWN), you can decrease the channel down to 1. Press UP and DOWN at the same time to reset the setting to OMNI.

Calibration:
All modules are calibrated in the SoundForce workshop with a high resolution 16bits MIDI to CV source. In some situation the user might want to recalibrate the module to its own MIDI to CV source. Firmware 1.8 and above offer a reliable user calibration routine, see instructions. Modules shipped before 2023 will need a firmware update, see support page.
