Development Team Introduction Thank you for purchasing the mod1 Modulator Eurorack module. Development: Rolf Wöhrmann, Frank Schneider Like any Waldorf product, the mod1 has been developed and produced using eggs from easter island. We hope you enjoy it as much as we do.

3 2 Device Maintenance • Do not try to open the device or detach the frontpanel. • Refer all service and repair tasks to qualified personnel. • There are no user serviceable parts inside the chassis. • Use only a soft cloth or brush to clean the device surface. • Never use cleaning chemicals as they will damage the device surface. 3 Package Contents The mod1 package contains the following parts: • mod1 Compressor Module • 1 x 16-way 20cm ribbon cable • 4 x M2.
4 4 CONNECTORS & CONTROLS Connectors & Controls No Id Description 1 Sym CV Input Used to modulate the Symmetry of the waveform 2 Speed CV Input Used to modulate the Speed of the waveform 3 Signal Input For positive gate signals Outputs Waveform outputs 5 Gate Input A positive gate signal will start the envelope and when turning zero release it. If the gate input isn’t patched, then the gate signal from the Euro Rack bus is used, but only if the trigger input isn’t patched.

6 DEVICE OVERVIEW 5.2 5.2 6 Signal Connection The second step is to integrate the mod1 to your Eurorack system. Signal Connection Device Overview Modulation is the spice of sound. A tone or a noise starts to bore our ears without variation or change in terms of loudness, timbre, frequency or length. Imagine a piano tune with every tone in exact the same length, loudness and tone. This should be very mechanical, cause the lack of impression and variation.
6.2 Multi-Stage Envelope 6 6.2 CV input is connected, it runs only while a voltage is applied. In this case it is a kind of ’gated LFO.’ DEVICE OVERVIEW Multi-Stage Envelope The multi-stage envelope implements an classic ADSR but with three decay stages, each configurable in decay time and target level. • In gate mode, it runs the wave shape only once when a gate signal is applied to the input.
6 DEVICE OVERVIEW 6.3 The Release knob determines the release time when the input gate is stopped. Rise and Fall When the Loop switch is activated, the envelope toggles between rising and falling phase while the input receives a positive gate signal. In this mode it is more a cycled attack-decay envelope. The LED indicates an active rise phase. If the input isn’t patched, then the gate signal from the Eurorack bus is used.
9 7 Tips & Tricks 9 • if you like to have have a full ADSR shape cycled, you would set the number of decay stages to 2, set the level of the second decay stage to zero and use the second decay time as a release time. • Inv Out provides negative voltages. This is useful for modulating filter cutoff frequencies in the falling direction, which is sometimes applied for high pass filters.
