Here is a DIY filterbank REPAIR story from JAPAN

Here is a Midi Console for the Filterbank for use inside of Digital Performer 3.02

Here is a "user's defined LOGIG ENVIRONMENT". This one is made on Logic 4 (PC-Version).

This drawing illustrates the pedal cirquit, suitable for the PEDAL INPUT of the Sherman Filterbank 2.
As "pedal pot" a 50 K (linear or log : to your taste) pot can be used too. The amount pot can be any dual pot, 100K linear. The switch can be of any type, usually the toggle switch of the pedal that toggles by pressing the pedal thoroughly. When the switch is open, the filterbank switches OUT1 and MAIN OUT in bypass, no matter the position of bypass-effect pot on the FB2. The green led, right on the FB2 indicates the the bypass/effect switching. This cirquit can also be built in a guitar or other instrument. Just watch out NOT to connect the earth (ring of the jack) of this cirquit to the earth (ring of the jack) of the guitar/instrument elements. You need an extra jack in the guitar isolated from the original jack. Another nice idea is using an LDR parallel with a resistor of 27 K, as replacement of the "pedal pot" in the guitar, and glue (use transparent glue) this behind a hole of approx 5 mm in the cover plate of the guitar. Awesome fast fingertip modulations can be played by covering/uncovering this hole from spotlight. The amount pot gives the weakest modulation round middle position, and in the (opposite) extreme positions, the strongest (opposite) modulation.

HOW TO DECREASE THE 100 Hz PWM NOISE

HOW TO MAKE YOUR OWN LFO OUTPUT

It is very simple to make your own LFO output :
Tap from the LFO led with a 1 K resistor for protection, and install an extra jack fot the LFO out.
The 2 pin’s of the led provides a different waveform.
