Filtering in general, and the Crumar Performer in particular
In the Solina, the signal as it comes from the tone generation and string sound shaping, runs thru a second order 12kHz filter before it goes into the BBDs. This acts as an anti-aliasing filter, as well as adding to the sound shaping a bit.
With longer BBD lines (TDA1022 instead of TCA350), the clock frequency can be higher, this allowing for a wider bandwidth without increased aliasing.
So I've implemented a 16kHz anti-aliasing filter, plus a 12kHz filter, to be able to choose a broadband sound vs. a slightly darker sound.
A third option was inspired by the Crumar Performer: It has a very specialized 3-Band EQ that is very effective on string sounds. With my Performer, I get very convincing, yet very different, string sounds with a 0-10-0 setting and with a 10-0-10 setting (low-mid-high).
I've included this wonderful EQ in my emulation.
First Step- sockets.. for 3 triple Chorus.
