Sherman filterbank Quad Modular Filter (QMF)

This is a limited edition piece of gear and only 95 of them were made world wide. It was the last one made by Sherman.
I AM THE FIRST OWNER and IT HAS BEEN USED A FEW HOURS !!!

It is basically four filter banks in one sleek modular machine with enhanced features and possibilities. It also features total midi implementation with independent 1-4 midi channels for each filter bank. Each has its own separate input and can function independently or all can be linked together for a MEGA filter with a 96dB slope !!! LFO outputs CV and Gate inputs and outputs allows you to create WILD filter effects while in the analog domain. Newly added features include a bright switch to boost high frequencies.
Description from the Sherman website:

'What is the Sherman QMF ?
4 Sherman Filterbanks in 1 box, numbered 1, 2, 3 and 4. The numbers also apply to the MIDI channel at which the 4 filterbanks are programmed. E.g. filterbank 1 has MIDI channel 1, filterbank 2 has MIDI channel 2 etc...

The 4 filterbanks have a separate input (i.e. you can plug in 4 different sound sources into the 4 different filterbanks, so actually it's some kind of weird mixing desk), or you can link them all together (i.e. when 1 input is used, you can process the source through all 4 filterbanks, and then you may have a filter slope of 96dB...)

EXTRA FEATURES IN THE QMF (that are not in the regular Filterbank):

Filters 3 & 4 have the following 6 extra switches (so 12 extra features in total) :
- BRIGHT : Boosts high frequencies at input
- LIMIT : Clips input signal at lower level, in favour of the self-resonating behaviour of the filters. Setting the in level extremely high will not blow away the filter reso waves in “limit”.
- SLOW : In position “SLOW” the average speed of the AD(S)R / env.follower slopes is as in a regular Filterbank. If “slow” is switched off, the AD(S)R / env.follower slopes are about 5 times faster.
- TRIGGER : Enables “a kind of” LFO restart at the “on”going AR TRIGGER.
- SAWTOOTH SELECT : Selects sawtooth waveform for the LFO.
- +1 OCTAVE : Doubles the center-frequency of both filters, even if in “no signal” position of the harmonics. Overrides the MIDI +1 octave function.
- 2 EXTRA JACK-SOCKETS ON EACH FILTER :
- LFO OUTPUT : To connect to ANY input : eg : AM, AM Depth, FM, AR trig; ADSR trig.
- AM DEPTH CV INPUT : Control Voltage input for the internal VCA that controls the flow from the AM source to the signal VCA's for Out1 and Main out. (in the manual, here is a drawing of the above described VCA connections)

FINISHING:
- Top layer of extra varnish on the painting (so the print of lines / numbers stays longer)

- 10 extra JACK-JACK cables of 60 centimeters delivered with each QMF
