Page 4: Installation
Installation Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power supply. We recommend you use Intellijel cases and power supplies. Before installing a new module in your case, you must ensure your power supply has a free power header and sufficient available capacity to power the module: ●... -

Eurorack case. Ensure the red stripe on the cable lines up with the -12V pins on the bus board. On Intellijel power supplies the pins are labelled with the label “-12V” and a thick white stripe. Sometimes the connectors are shrouded, ensuring the cable can only be oriented in one direction. - Page 6 Bifold Manual Once connected, the cabling between the module and power supply should resemble the picture below: Before reconnecting power and turning on your modular system, double check that the ribbon cable is fully seated on both ends and that all the pins are correctly aligned.

Page 7: Overview
Overview Bifold is a dual channel wavefolder, where one channel (the P channel) has a sonic characteristic inspired by the Buchla-style P arallel “deadband” folding circuit, while the other channel (the S channel) is more characteristic of a Serge-type S erial folding circuit. -

Bifold Manual Bifold Front Panel Controls FOLD knob - This knob sets the initial amount of wave folding applied to both the IN P (parallel) and IN S (serial) folders and sent to the OUT P , OUT S and MIX outputs. - Page 9 Bifold Manual feeding equal signals into the MIX output at the noon position. When fully clockwise, only the S erial circuity is heard at the MIX out. You can choose whether to feed the crossfader with either channel’s unfolded (dry) signal ( IN P...
- Page 10 Bifold Manual SYM-X-AUX switch for Serial Folder - The position of this switch affects the signal being fed into the S erial folder. Specifically: SYM - When set to SYM (up position) a DC offset of up to ±5V is added to the IN S...
- Page 11 Bifold Manual SYM-AUX attenuverter for Serial Folder - Depending on the setting of the S erial folder’s SYM-X-AUX switch the knob either attenuverts a 5V DC offset voltage (when set to the “SYM” position) or it attenuverts the AUX input voltage (when set to the “AUX”...
- Page 12 Bifold Manual XFADE S input selector switch - The position of this switch selects the signal source that feeds into the crossfader’s S -side input (clockwise rotation of the XFADE knob), which is then mixed with the selected P -side input and sent through to the MIX output.
- Page 13 FOLD P voltage is used to control folding. NOTE: If nothing is plugged into the FOLD P jack, then Bifold internally normals +5V to that jack, meaning this knob acts as a 0V (counterclockwise) to +5V (clockwise) attenuator. IMPORTANT: If the FOLD...

Page 14: Inputs And Outputs
Bifold Manual Inputs and Outputs OUT P - Output of the P arallel wavefolder circuit. OUT S - Output of the S erial wavefolder circuit. MIX OUT - Output of the mixed (crossfaded) P arallel and S erial folder circuits. - Page 15 SYM-AUX attenuverter [5, 6] If nothing is patched into the AUX input, then Bifold’s output feeds the AUX input. FOLD P CV IN - This input accepts a ±10V control voltage for externally controlling the amount of folding applied to the P arallel wavefolder.
- Page 16 Bifold Manual the FOLD knob is higher than its minimum position, then negative voltages applied to FOLD S decrease the folding, and positive voltages increase it. If nothing is plugged into either this jack or the FOLD P jack, then +5V is internally applied, which can be attenuated...

Page 17: Usage Scenarios
Crossfading Folded and Unfolded Waveforms You can use Bifold to mix together two different waveforms from a single (or multiple) oscillators — one folded and one unfolded — then crossfade between them to create complex and evolving waveforms. -
Page 18: Stereo Folding
Bifold Manual Stereo Folding Some very interesting stereo effects can be achieved by sending OUT P to one stereo channel, and the OUT S jack to the other. For example: 1. Patch a waveform into the IN P jack and leave the IN S jack unpatched. -
Page 19: Ring Modulation
XFADE input, and sent to the MIX output. Amplitude Modulation You can also use the Bifold to create Amplitude Modulation (AM). To do so: 1. Follow steps 1-6 in the Ring Modulation description, above. 2. Plug a dummy cable into IN S 3. -
Page 20: Random Noise Generation
Bifold Manual Random Noise Generation Use the module’s built-in feedback path to create all manner of strange and chaotic blips, hisses and noise bursts. To do so: 1. Unpatch everything except the MIX output. 2. Set both the Parallel and Serial SYM-X-AUX switches [3, 4] to the AUX (bottom) position.
