This is a quick demo of a prototype of the Quad Multi-Mode Gates.
Only the Doepfer monster case was used, everything is just blinking alluringly, attempting to distract you (worked on me!).
- Doepfer A-155 randomly sequencing a Livewire AFG sine,
- Doepfer A-147 square wave clocking Doepfer A-149-1/2,
- Doepfer A-149-2 random gates triggering QMMG CV triggers and CV resonance in no particular order,
- QMMG master out lightly treated with Doepfer A-199 spring rev & Doepfer A-188-1Y (256) (CV2 modded with A-149-1)
This is a prototype QMMG, and the patch uses 2 of the 4 modes.
Here’s the details on the QMMG:Quad Multi-Mode Gates (QMMG)
A huge riff on the original Buchla 292 Quad Lo Pass Gate, including a Mix Out and containing no fewer than 8 vactrols.
The QMMG offers the additional features of High Pass Gate mode, Voltage Controlled Feedback, Direct Coupling (for processing of Control Voltages) and Normalizations so that multiple channels may easily be used together to create Bandpass Gates, steeper HP or LP Gates or even something like a traditional Synthesizer Voice Architecture.
The voltage controlled feedback is routed differently in each mode.
In VCA mode it is routed to provide slightly non-linear GAIN. Daisy chain multiple channels for voltage controlled clipping. In BOTH Mode the feedback is routed to provide DAMPING of the ringing vactrols. The effect of adding feedback in BOTH mode is not unlike placing your hand upon the head of a drum, while striking, thus allowing the user to control how much the Vactrols ring. In the LP and HP modes, the feedback is routed to provide a very wicked, highly unstable, non-linear resonance. At higher settings, the positive and negative portions of the signal will develop different resonant peak frequencies, and further, they will clip asymmetrically. The filter can be slippery and smooth at low resonance settings, but it cuts like a choir of daggers at high resonance settings.
The benefit of Direct Coupling is that a channel of the QMMG could be used to attenuate or amplify an incoming CV before applying to another channel. The mixing section is set-up so that inserting a plug at the output socket of any given channel removes that channel from the mix, therefore you could use one half of the QMMG for voltage controlled mixing of CVs to apply to the other half being utilized for signal processing.
This module is 24HP and consumes 60mA worth of current. The price is TBD.
