One quirk of the module is the relatively sluggish response time, especially on the down-slope, this adds to the plucky sound and also gives a natural ‘release’ to the CV, meaning it works very nicely by simply feeding a gate signal into the CV input without the need for an envelope. This release is dependent again on the tone setting, so the darker setting has a shorter release compared to the bright setting which has a very long release.
