The Takaab EG is a full-featured ADSR envelope generator with looping mode in 6HP, expandable to be fully voltage-controllable by adding the EG-CVX expander module. The EG is digital at its core, based on the fantastic ENVGEN8 chip by Electric Druid. The Takaab EG and EG-CVX together replace and expand on the function of our discontinued VC-EG module.

There are three modes of use:
EG is the normal 1-shot ADSR mode, reacting to a standard gate input.
In LFO mode the module loops constantly through the 4 stages of the envelope regardless of any gate input (release happens as soon as the decay drops down to the sustain level). With the addition of the EG-CVX, this makes it a fairly powerful, uni-polar voltage controlled LFO, capable of frequencies up to 300Hz.

The center position is GATE mode, which is the same as LFO mode but only loops as long as a gate is being received at the main gate input.
Attack, decay, and release parameters range from a very snappy 1ms up to over 10 seconds.


There are a number of jumpers on the board and on the expander port.

To use the EG without the expander there are 6 jumpers that need to be placed on the EG-CVX port, otherwise the module won't work. The EG is shipped with these jumpers already in place and there is a diagram on the board which shows where they go. (For reference the connections to be made are: pins 7-8, pins 9-10, pins 11-12, pins 13-14, pins 15-16 and pins 17-18).

There are also two jumps that can be made that affect the shape of the envelope, these are selectable by switches on the EG-CVX, but without the the CVX you can use jumpers: 1) Jump pins 3-5 to get a linear response envelope shape, omit this jumper for exponential. 2) Jump pins 4-6 to get punch mode which adds an extra 5ms flat stage between Attack and Decay. This gives some extra punch, most noticeable on shorter, snappy sounds.

'GATE Bus' jumper on the EG normalises the gate bus from your eurorack power distribution to the Gate input of the EG.
