Tactical expansion unit for Bionic Lester mk1 by Industrial Music Electronics ︎︎︎ Connects behind the scenes via a 14-pin ribbon connection.
Individual filter responses from Lester are normalled to two bi-polar mixers respectively, allowing for scultping of new response types, which are available at the sum output. Each normalled connection to Lester can be overridden by patching an external signal to any of the mixer's inputs.
Each mixer's sum is normalled to a vca-controlled feedback path back into its respective filter's core. The operation of this feature is managed by each of the switches for each mixer. In the down position, no signal is fed back via the vca unless a control signal is present at the cv input (which expects unipolar signals, unity gain is roughly 5v). With no cv present, this switch acts as a master feedback path mute. When the switch is in the up position, a fixed bias is connected to the vca cv control and the mixer sum is fed back continuously.
Since it is DC coupled, when Æ is not connected to the Bionic Lester, it can act as a standalone dual bi-polar mixer for cv or audio signals.
