EG

Looping ADSR Envelope Generator

Part of the Takaab range of modules by Siam Modular.

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.

JUMPERS:
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.
