A-143-4 Quad VCLFO/VCO
Vorankündigung / preliminary

• four independent VCLFOs/VCOs with triangle core
• two frequency control CV inputs for each unit: CV1 without attenuator (~ 1V/oct), CV2 with attenuator
• manual frequency control
• frequency range switch
• LED display (useful only for LFO range)
• triangle and rectangle outputs for each unit
• common control section with two CV inputs and manual control (these inputs and controls affect the frequency of all four units)
• sum outputs for triangle and rectangle (with internal jumpers that define which outputs are summed)

This is a preliminary information about the planned module. The features are still subject to change and all specifications are still preliminary without any obligation !

Current state (as of November 2009): We are about to add a temperature compensation and to improve the 1V/Oct tracking so that the module may be used as four "real" VCOs too. We also have to find out if there are locking problems if the frequencies of two or more oscillators are nearly the same. Details will follow as soon as the corresponding measurements have been finished.

Current state (as of February 2010): Several interested customers mentioned that a reset/sync input for each VCLFO/VCO would be desirable too. We are about to find out how much this would increase the price and delay the release date because it requires a total re-design of the pc board (not just a few small modifications).
