Erbe-Verb
Limited WARRANTY: Make Noise warrants this product to be free of defects in materials or construction for a period of one year from the date of purchase (proof of purchase/invoice required). Malfunction resulting from wrong power supply voltages, backwards power cable connection, abuse of the product or any other causes determined by Make Noise to be the fault of the user are not covered by this warranty, and normal service rates will apply.
Installation: The Make Noise Erbe-Verb is an electronic signal router requiring 149mA of +12V and 13mA of regulated power and a properly formatted distribution receptacle to operate. It is designed to be used within the euro format modular synthesizer system. Go to http://www.doepfer.de/a100_man/a100t_e.htm for the details of this format.
1b 2a 2b 3a 1a 3b 4a 5a 4b 5b 4c 5c Erbe-Verb Panel Controls 1a. Signal IN: AC coupled, expects standard signal level of 10Vpp signal. 1b. Level Control for Signal IN: unity at 3 o' Clock 2a. MIX CV IN: unipolar control input. Range 0V to +5V. 2b. MIX Panel Control: blends between DRY (un-processed) signal & WET (processed) Signal. Operates as Combo Knob, with nothing patched to MIX CV IN, works as standard panel control. With Signal Patched to MIX CV IN, works as attenuator for that signal. 3a.

Getting Started: Patch the signal to be processed into the SIGNAL IN (1a). The associated Level Control (1b) accommodates modular synthesizer signals of 10Vpp with unity gain at around 3 o' Clock. Beyond 3 o' Clock on the Level Control, there will be some gain and possibly clipping followed by digital overloading. Take your output from the LEFT OUT (3a) and patch to your final mixer/ monitoring system. If you have Stereo monitoring, patch both LEFT OUT (3a) and RIGHT OUT (3b) to your Stereo monitor inputs.
Predelay (cont’d) In addition to being wide ranging and completely independent of the Size parameter, the Erbe-Verb Pre-Delay is also able to be synchronized to the rest of the modular system. Using the TEMPO IN (12a), it may be synced to a division (CW from NOON) or multiple (CCW from NOON) of the clock patched to TEMPO IN (12a). This is highly un-realistic. Nowhere in nature is the trajectory of sound synchronized to a machine. The Reverse function reverses time by playing the Pre-Delay buffer backwards.
Internal Modulation (Speed and Depth) Decay is also greatly influenced by the SPEED (5a, 5c) and DEPTH (6a, 6b, 6c) settings since the Internal Modulation has the potential to take energy away from the reverb process, which results in decreasing settle times. For example setting Depth and Speed to about 4 o' Clock will smooth out resonances in the space and cause the reverb to settle more quickly.
Absorb (cont’d) Diffusion: Diffusion controls the degree to which initial reverb density increases over time. High amounts of Diffusion result in fast initial buildup of echo density; low amounts cause slow initial buildup. Diffusion is also affected by Size — smaller spaces will sound denser because the sound travels shorter distances before reflecting and returning to the listener. Diffusion is also related to the shape and construction of a room.
Emulating Typical Reverb Rooms : Note: For all algorithms, Size, PreDelay and Decay settings are given. Small variances in these three controls will alter the room. Set Speed and Depth to 12:00, and Absorb full CCW, unless otherwise noted, then set Tilt to taste to fit the sound into the mix. Keep in mind that these are starting points, and many spaces in between are possible by taking any control out of its comfort zone.
Patch Ideas: Gated Reverb: Set all controls to taste, using one of the above "typical" settings if desired. Mult audio source to Erbe-Verb signal IN, and to Ch1 or Ch4 signal INput of MATHS, or to the signal INput on Function. Set Rise to 12:00, Fall full CCW, response to Linear. Take Unity/Positive channel output to Erbe-Verb MIX CV In. Set Mix panel control to taste (recall that it will act as a CV Input attenuator in this patch). Adjust Rise, Fall and Response for the desired gating length and shape.
