Most extreme on the planet
(Limited Edition only 95 pcs made, all sold out)
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 sign) : 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)
