Cwejman QMMF-4


The big, sorry HUGE brother of the great RES-4 even outperforms it's concept by far. This module are four ultra stable multimode filters / resonators with three different resonance modes, three switchable filter types (plus a fixed notch), individual in- and outputs per filter and the Master section known from the RES-4 plus dry/wet controls.
What a monster module for filter and resonator use, generating drum sounds, equalizing etc.

We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)



Each filter has an individual audio input, two controls for coarse and fine adjustment of cutoff frequency, two cutoff CV inputs (CM1 adjustable, CM CAL with 1V/oct) as well as the voltage controllable Q-PEAR resonance circuit with three modes: OSC allows for self-oscillation, OSC SAT as well but with saturation (like the MMF-2), RES doesn't self oscillate but is perfect for filter ringing (like the RES-4).
Switchable filter types are low pass, band pass and high pass; the notch is available separately
The filter is followed by a VCA (output fader) with the according LEVEL CV input. The LP/BP/HP signal can be output both pre fader and post fader (pre or post VCA), the notch is not affected by this.

The master section affects and controls all four filters simultaneously, in addition to the individual CVs. The section has a master cutoff control with a Freq CV input, a master audio input sending it's signal to all four filters. The dry/wet control is voltage controllable, the wet signal's level can be set separately and is voltage controllable. The master notch output carries the mix of all notch filters, the MMF output the mix of all multimode filters.


We currently do not accept pre-orders for Cwejman modules. For some products, there are waiting lists with pre-orders from the years 2013 to 2017, which are being processed as a matter of priority.
If you’d like to be informed as soon as this module is back in stock, please activate the availability notification via e-mail.
Please note: The number of Cwejman modules is always limited and much lower than the number of interested parties. Therefore, we recommend to order IMMEDIATELY and ONLINE if a Cwejman product becomes available. Enquiries via e-mail or telephone are usually not fast enough.
If the demand is higher than the supply, unfulfillable pre-orders will be deleted. In this case you’ll receive an e-mail. (Pre-orders on the waiting lists mentioned above are excluded from this policy.)
